  3. 3. The Department of Environment, Health & Safety (EHS)  Mission Statement:  We support the University’s core mission of teaching, research, and service by providing comprehensive environmental, health, and safety services to the University community including:  Education through training and consultation  Maintaining a safe work environment  Ensuring regulatory compliance  Controlling recognized health and safety hazards  To achieve this mission we must rely on the Division of Laboratory Animal Medicine employees to understand and recognize safety policy and procedures.
  4. 4. Purpose and Responsibility of EHS  EHS is responsible for developing and maintaining a comprehensive program to comply with the following agencies and regulations:  Environmental Protection Agency (EPA)  Occupational Safety and Health Administration (OSHA)  NC Department of Environment and Natural Resources (NCDENR)  Joint Commission on Accreditation of Healthcare Organization (JCAHO)  NC Radiation Protection Section (NCRPS)  Office of State Personnel (OSP)  NC Fire Prevention Codes  NFPA 101 Life Safety Codes  NC Medical Waste Policy  EHS performs periodic inspections of UNC-CH facilities to identify problem areas and to assist departments in identifying needs  EHS staff is also available for consultation on recognized or suspected hazardous conditions.
  5. 5. Sections of EHS  EHS provides comprehensive support for the University community in the areas of environmental compliance and occupational health and safety.  To learn more about each section, click on the buttons below: Director Biological Safety Environmental Affairs Fire Safety and Emergency Response Occupational and Environmental Hygiene Chemical Safety Radiation Safety Workplace Safety
  6. 6. Workplace Safety Program  According to University policy and North Carolina General Statute Article 63, each state agency must have a written Health and Safety program with clearly stated goals or objectives that promote safe and healthful working conditions.  The Environment, Health and Safety Manual along with other specific manuals, such as Biological, Laboratory and Radiation Safety Manuals serve as the University’s written Health and Safety program.  These manuals provide University employees with the necessary guidance in maintaining a safe work environment. Each of these manuals can be viewed in more detail by selecting “Manuals” from the EHS web site.
  7. 7. Elements of Workplace Safety Program  Conduct new employee training to help with the identification of and correction of hazards.  Review workplace incidents and develop ways to eliminate or minimize hazards.  Employee input through safety committees.
  8. 8. Workplace Safety Committees  Duties and Responsibilities:  Perform workplace inspections  Review injury and illness records  Make advisory recommendations to the administration through committee structure shown  Perform other functions determined by the State Personnel Commission  UNC employees should contact EHS or any committee member regarding safety concerns  The Hazards Management Safety Committee oversees issues related to DLAM employees  Two representatives from DLAM sit on this committee  If you are interested in serving on one of the committees please feel free to contact the EHS office at (919) 962- 5507.
  9. 9. Investigations  Request for Special Safety Investigation  The Occupational Safety and Health Act of North Carolina provides that employees may request an inspection or evaluation of conditions which they believe may constitute a health or safety hazard.  University employees are encouraged to request a “Special Investigation” into the need for corrective action by contacting EHS at (919) 962-5507.  Employees are also guaranteed the right to request an inspection from the State Department of Labor (1-800-LABOR NC) by giving notice to them of a violation of a safety or health standard that he/she believes threatens physical harm or constitutes immediate danger.  The rights of an employee in reporting complaints of matters affecting environment, health and safety shall be exercised without retaliation on the part of any other person.  Anonymous Investigations  Persons requesting an inspection by EHS may request confidentiality and, by law, their name will not appear on any record published, released, or made available to the public or to the immediate supervisor or department head.
  10. 10. Fire Safety Program  UNC’s Fire Safety program is based on NFPA 101 Life Safety Code, N.C. Fire Prevention Code, and OSHA 1910 Subpart E.  Understanding fire safety is the key to an effective fire protection program for the University.  Regularly inspect your work area for the following:  Electrical hazards  Storage in hallways  Blocked exit ways  Adequate lighting of exits  General housekeeping  Inspecting your work area can prevent a fire from occurring and provide employees with a safe passage in the event of a fire.  Report any fire hazards or other safety concerns immediately to the department of Environment, Health and Safety at (919) 962-5507.
  11. 11. Egress  If a fire or other emergency occurs in your building, employees must know two Means of Egress (exit).  OSHA defines Means of Egress as “A continuous and unobstructed way of exit travel from any point in a building or structure to a public way.”  The three main components of Means of Egress are:  The way of Exit Access  The Exit  The way of Exit Discharge
  12. 12. Components of Egress Exit Discharge is the exit from a building to a public way. Exit is the protected way of travel to the exit discharge. Exit Access is the area in which an employee uses as their means of exiting to an exit.
  13. 13. Emergency Action Plan  EHS has a general Emergency Action Plan for the University to follow  An Emergency Action Plan is a “plan for the workplace describing what procedures the employers and employees must take to ensure employee safety from fire and other emergencies”.  This plan includes the following:  Posting of planned evacuation routes  Procedures to follow in the event of a fire or emergency  Procedures to account for employees after evacuation  Procedures for employees who remain to operate critical equipment in an emergency
  14. 14. Building Evacuation Procedures  Building evacuation procedures should be posted on the office bulletin board and at all elevators.  Employees should know at least two evacuation routes for their designated work area and in any area they frequent often.  Employees are encouraged to evaluate the building evacuation areas daily to ensure that there are no obstructions.  If obstructions are found, please report it to EHS immediately at (919) 962-5507.
  15. 15. Fire Emergency Procedures  If a fire emergency occurs in your workplace, it is vital that you are prepared to react.  The acronym RACE provides the basic steps of the Emergency Action Plan:  Remove or rescue individuals in immediate danger  Activate the nearest fire pull station and call 911  Confine the fire by closing windows, vents and doors  Evacuate to a safe area (know the evacuation routes for your area)
  16. 16. Emergency Coordinators  Emergency Coordinator(s) have been designated for all occupied buildings.  Each EC is responsible for assisting in the safe evacuation of employees.  Prior to an emergency, the EC completes an information card that includes:  Evacuation monitors’ names  Employee names and phone numbers occupying building  Location of employees needing assistance  Rooms containing hazardous material  Equipment needing special attention  To obtain the name of your building’s Emergency Coordinator contact the Fire Safety section at EHS at (919) 962-5507.
  17. 17. Fire Extinguishers  Extinguishing a fire requires the appropriate determination of which type of fire extinguisher to use. There are three classes of fire extinguishers to choose from:  Class B A fire extinguisher labeled with letter "B" is for use on Class B fires. Class B fires are fires that involve flammable and combustible liquids such as gasoline, alcohol, diesel oil, oil-based paints, lacquers, etc., and flammable gases.  Class C A fire extinguisher labeled with letter "C" is for use on Class C fires. Class C fires are fires that involve energized electrical equipment.  Class D A fire extinguisher labeled with letter "D" is for use on Class D fires. Class D fires are fires that involve combustible metals such as magnesium, titanium and sodium.  DLAM areas are equipped with ABC type extinguishers.  Fire Extinguisher Maintenance  Insure the extinguisher is located in its proper location, properly located in plain view and its access is unobstructed.  Lab personal should ensure monthly that the pressure gage pointer (ABC type only) is within the green operable pressure range.  Ensure safety pin and inspection tamper seal are in place.  Annual hands-on fire extinguisher training is not required for DLAM employees but can be requested by contacting EHS at (919) 962-5507.
  18. 18. Using the Fire Extinguisher  The acronym PASS will assist in remembering the proper use of a fire extinguisher:  Pull the pin between the handles  Aim the nozzle at the base of the fire  Squeeze the handles together  Sweep the extinguisher from side to side  Stand six to eight feet away from the fire with your back to the exit.  If the fire does not begin to immediately go out, evacuate the area.
  19. 19. Fire Prevention  Electrical Hazards include the following:  Defective outlets  Broken plugs and frayed cords  Plugs with missing ground prongs  Missing covers on junction boxes  Missing covers on wall receptacles  Use of electrical “octopuses” to obtain more outlets  Do not use extension cords through doorways or in place of permanent wiring  Make sure all electrical outlets are covered before spraying room or floors with water based cleaners/disinfectant
  20. 20. Workers Compensation Program  Workers Compensation benefits are available to any University employee (whether full-time, part-time or temporary) who suffers disability through accident or illness arising out of, and in the scope of, his or her employment, according to the North Carolina Workers Compensation Act.  The benefits provided to University Employees include medical and leave:  Medical Benefits – include all authorized medical services such as physician visit, prescriptions, physical therapy, rehabilitation, etc.  Leave Benefits – are provided to employees when an authorized medical provider places an employee out work.  For further information concerning University policies on workplace injuries and illnesses, refer to the Workers Compensation section on the EHS web site.
  21. 21. Medical Treatment  If you have an occupational injury or illness report directly to the University Employee Occupational Health Clinic (UEOHC).  The UEOHC is located at 145 Medical Drive and is open from 8:30am to 4:30pm Monday through Friday, except holidays.  For after hours needlestick/human blood or body fluid exposures, please call UEOHC at 966-9119. The UEOHC line will automatically forward your call to Healthlink in order to gather the appropriate information and put you in contact with the Family Practice physician covering the needlestick hotline.  For all other after hours work related injuries that require immediate medical care, go directly to the UNC Emergency Department. If immediate medical care is not needed, then please report to the UEOHC the following day.  For a life-threatening injury or illness, call 911 or report to the Emergency Department located in the Neurosciences Hospital on Manning Drive.
  22. 22. On-the-Job Injury or Illness  Report the incident to your supervisor immediately no matter how minor.  Once the injury or illness is reported, an accident investigation will occur to determine the cause of incident and corrective action taken to prevent the incident from reoccurring.  A NCIC Form 19 must be completed  Please note: Failure to report an incident could result in denial of a workers compensation claim.
  23. 23. Hazard Communication Background What is OSHA’s Hazard Communication Standard? OSHA’s Hazard Communication standard (29 CFR 1910.1200), promulgated 1994, requires that employees be informed of the hazards of chemical(s) that they work with or are present in their work area.
  24. 24. OSHA Hazard Communication Standard (continued) The four elements of the program include:  Ensuring chemicals are labeled  Maintaining departmental/work unit/laboratory chemical inventories  Maintaining Material Safety Data Sheets (MSDS)  Training of personnel by Supervisor on the chemicals that are used or in the workplace
  25. 25. OSHA collaborates with United Nation To view details of this report, double click picture. Understanding the need for consistent classifications of hazards chemicals, OSHA decided to better align with the United Nations’ Globally Harmonized System by adopting a common classification and labeling of chemicals.
  26. 26. Benefits of Adopting GHS There are several benefits for OSHA in adopting the Globally Harmonized system. In particular, it will provide a common and coherent approach to classifying chemicals and communicating hazard information on labels and safety data sheets. Thus resulting in: • Consistency of information provided • Increase comprehension of hazards • Help address literacy problems • Facilitation of international trade of chemicals
  27. 27. OSHA Publishes Revised Standard In March 2012, the revised Hazard Communication Standard became law and included an established timeframe for implementation. The table below outlines the effective dates, requirements and responsible parties. Effective Completion Date Requirement(s) Who December 1, 2013 Train employees on the new label elements and SDS format. Employers June 1, 2015* December 1, 2015 Comply with all modified provisions of this final rule, except: Distributors may ship products labeled by manufacturers under the old system until December 1, 2015. Chemical manufacturers, importers, distributors and employers June 1, 2016 Update alternative workplace labeling and hazard communication program as necessary, and provide additional employee training for newly identified physical or health hazards. Employers Transition Period Comply with either 29 CFR 1910.1200 (this final standard), or the current standard, or both All chemical manufacturers, importers, distributors and employers
  28. 28. Benefit of HazCom2012 With the University’s mission to “serve North Carolina, the United States, and the World through teaching, research, and public service,” the new requirements under HazCom 2012 will enhance clarity for University employees positioned on campus as well as abroad.
  29. 29. HazCom2012 Requirements By December 2013, all University employees are to have received general training regarding “definitions”, “label” and “Safety Data Sheet” for chemicals under new HazCom 2012 standard. Supervisors are still required to provide job specific training to employees on the chemicals used in their area at least once and every time a new chemical is added. The training must cover proper use, handling, and personal protective equipment required for the safe handling of the hazardous chemicals.
  30. 30. Definitions HazCom 2012 will use a “specification” approach rather than a “performance-oriented” approach. Hazards will be classified thus providing a specific criteria for classification of health and physical hazards, as well as classification of mixtures. Specifically:  Appendix A defines health and physical hazards  Appendix B includes additional parameters to evaluate health hazard data  Appendix F pertains to Carcinogens
  31. 31. Labels HazCom 2012 requires chemical manufacturers and importers to provide a label that includes a harmonized product identifier, pictogram, signal word, and hazard statement for each hazard class and category. Precautionary statements must also be provided.
  32. 32. Labels - Pictograms Pictograms are required on labels to alert users of the chemical hazards to which they may be exposed. Each pictogram consists of a symbol on a white background framed within a red border and represents a distinct hazard(s), such as health, physical, and environmental . The pictogram on the label is determined by the chemical hazard classification. There are nine pictograms with only the environmental pictogram being optional.
  33. 33. Labels – Distinct Hazards As previously stated, “Distinct hazards” are chemicals in which there is scientific evidence that a health, physical, and/or environmental hazards may occur.  Health Hazard - acute or chronic health affects may occur if exposed.  Physical Hazard - a combustible liquid, a compressed gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or water-reactive  Environmental Hazard – pose risk or danger to the environment
  34. 34. Labels – Pictograms (Health)  Acute Toxicity (fatal and toxic)  Fatal in contact with skin  Fatal if inhaled  Fatal if swallowed  Toxic if swallowed  Toxic in contact with skin Examples: Carbon Monoxide, Ammonia, Acrylonitrile, Arsenic Skull and Cross Bones will appear on the most severely toxic chemicals. Depending on the toxicity of the chemical, the skull and crossbones indicates that the chemical may be toxic or fatal. Specifically it can mean:
  35. 35. Labels – Pictograms (Health)  May be corrosive to metals  Causes severe skin burns  Causes serious eye damage Examples: Sodium Hydroxide (lye) and Sulfuric Acid Corrosive will appear on chemicals that have corrosive properties. Depending on the properties of the chemical(s) in the product, the corrosion pictogram can mean:
  36. 36. Labels – Pictograms (Health)  Harmful if swallowed  Acute Toxicity (harmful)  Harmful in contact with skin  Skin Sensitizer  Harmful if inhaled  Respiratory Tract Irritant  Causes skin irritation  Irritant (skin and eye)  Causes serious eye irritation  May cause allergic skin reaction  Hazardous to Ozone Layer Examples: Isopropyl Alcohol, Ethyl Alcohol, Acetone Exclamation Mark will appear on chemicals with less severe toxicity. This symbol will never be used with “skull and crossbones” symbol. Depending on the health hazard, it can mean:
  37. 37. Labels – Pictograms (Health)  Carcinogen  Mutagenicity  Reproductive Toxicity  Respiratory Sensitizer  Target Organ Toxicity  Aspiration Toxicity Examples: Carbon Monoxide, Hexanes Health Hazard will appear on chemicals with less severe toxicity. This symbol will never be used with “skull and crossbones” symbol. Depending on the health hazard, it can mean:
  38. 38. Labels – Pictograms (Health/Physical) Gas Cylinder can cause fires, explosions, oxygen deficient atmospheres, toxic gas exposures as well as the innate physical hazard associated with cylinders under high pressure  Gases under pressure  Compressed gases  Liquefied gases  Refrigerated liquefied gases  Dissolved gases Examples: Butane and Propane
  39. 39. Labels – Pictograms (Physical) Exploding Bomb symbol will appear on chemicals that have explosive properties.  Unstable Explosives  Self-reactive substances and mixtures  Organic peroxides Examples: Nitroglycerine and TNT, Gunpowder, Rocket propellants, and Pyrotechnic mixtures (fireworks).
  40. 40. Labels – Pictograms (Physical)  Extremely flammable gas  Extremely flammable aerosol  Self-Heating  Flammable aerosol  Extremely flammable liquid and vapor  Highly flammable liquid and vapor  Flammable liquid and vapor  Flammable solid Examples: Butane, Pyrophorics, Organic Peroxides Flame symbol will appear on chemicals that are flammable. Depending on the properties of the chemical(s) and the product, the flame can mean:
  41. 41. Labels – Pictograms (Physical) Flame over circle symbol will appear on chemicals that are:  Oxidizers  Oxidizing gases, liquids, and solids Examples: Hydrogen Peroxide and Nitrous Oxide
  42. 42. Labels – Pictograms (Environment) Environment symbol will appear on chemicals which are acutely hazardous to fish, crustacean, or aquatic plants. This is the only symbol that is not mandatory.  Aquatic Toxicity  Acute hazards to the aquatic environment  Chronic hazards to the aquatic environment
  43. 43. Label – Signal Word A Signal Word is used to indicate the relative level of severity of hazard and alert the reader to a potential hazard on the label. The signal words used are:  "Danger" - used for the more severe hazards  “Warning" - used for less severe hazards.
  44. 44. Labels- Hazard Statement A Hazard Statement describes the nature of the hazard(s) of a chemical, including where appropriate the degree of hazard. All of the applicable hazard statements must appear on the label.
  45. 45. Labels – Precautionary Statement A Precautionary Statement is a statement that describes recommended measures that should be taken to minimize or prevent adverse effects.
  46. 46. Label – What do UNC Employees need to do? Effective June 1 2015, all chemicals received at the University should have the required label. Any material transferred to another container must also have the same label versus just chemical/product name.
  47. 47. Safety Data Sheets HazCom 2012 requires Safety Data Sheets - SDS (formerly known as Material Safety Data Sheets – MSDS) to use a specified 16-section standardized format. Under the new format, employees wanting information regarding Exposure Controls/Personal Protection will always refer to Section 8 of the Safety Data Sheets.
  48. 48. Safety Data Sheets To improve employee understanding, information listed on the label, like Precautionary Statement, will be same information the employee will find on the Safety Data Sheet. The standardize 16 sections is broken down as follows:
  49. 49. Safety Data Sheet – 16 Sections 1. Identification of the substance or mixture and of the supplier 2. Hazards identification 3. Composition/information on ingredients Substance/Mixture 4. First aid measures 5. Firefighting measures 6. Accidental release measures 7. Handling and storage 8. Exposure controls/personal protection 9. Physical and chemical properties 10. Stability and reactivity 11. Toxicological 12. Ecological information (non mandatory) 13. Disposal considerations (non mandatory) 14. Transport information (non mandatory) 15. Regulatory information (non mandatory) 16. Other information including information on preparation and revision of the SDS
  50. 50. Safety Data Sheets – What do UNC Employees need to do? By December 2015, distributors must provide the new format of Safety Data Sheets. Supervisors need to update the Safety Data Sheet notebooks and/or computer links in their job specific area to the newly format sheets. Remember SDS(s) must be accessible to employees at all times.
  51. 51. NC OSHA– Enforcement By June 2016, NC OSHA will begin to enforce compliance with HazCom 2012 by conducting site evaluations. Environment, Health and Safety will continue to assist University departments with the implementation of the specific requirements covered in this training.
  52. 52. Resources - OSHA’s HazCom2012 Web Page OSHA has developed an extensive web page to provide additional resources for employees at http://www.osha.gov/dsg/hazcom/index.html
  53. 53. Resources - Guidance & Outreach Supervisors can find printable guidance material that can be utilized when training employees. • Guidance » OSHA Briefs » Fact Sheet » Quick Cards
  54. 54. Asbestos on Campus  As an employee of UNC, EHS is informing you of the presence of asbestos- containing materials in residence halls and campus buildings. Provided the materials are in good condition, they pose no health risk to the building occupants. http://ehs.unc.edu/ih/asbestos  UNC has an Asbestos Control Policy and Program to manage asbestos on UNC's campus.  Materials containing asbestos may include flooring, ceilings, walls, thermal system insulation on tanks, pipes and other miscellaneous materials.  UNC maintains asbestos-containing materials so they do not release asbestos fibers into the air. When asbestos containing materials become damaged, isolation, repair and/or removal are implemented immediately.  The University has a staff of accredited professionals that conduct building inspections, coordinate and supervise asbestos related construction activities, perform air monitoring and provide employee training.  If you have any questions concerning asbestos in a specific building on campus, please feel free to contact EHS at 919-962-5507 to make an appointment to review the building inspection reports.
  55. 55. Minimizing Hazards  There are three main controls used to eliminate or minimize workplace hazards:  Administrative – policies and procedures that control the time and amount of exposure.  Rest breaks  Standard Operating Procedures (SOPs)  Engineering – physical changes to the workplace to reduce or minimize a hazard.  Biological safety cabinets  Chemical fume hoods  Ventilated dumping stations  Personal Protective Equipment (PPE) – equipment you wear to protect the head, face, eyes, feet, respiratory system, hearing and body from injury.  Where possible, engineering and/or administrative controls should be attempted before requiring PPE.  When PPE is necessary, it is provided to employees at no cost.  Your supervisor should issue the appropriate PPE for your job duties.
  56. 56. Fundamentals of PPE  Each DLAM facility supervisor is responsible for reviewing the use and care of PPE required for each job function.  This required training is documented by the supervisor and employee signing the “Certificate of Personal Protective Equipment Training” as part of the facility Hazard Management Plan (HMP).  PPE should always be inspected prior to use to make sure it is sanitary and in good working condition (check for holes, scratches, cracks, frayed parts).  A good work practice is to clean reusable PPE before storing it.  All PPE should be stored in a cool, dry, secure area.  Earplugs and N-95 respirators should never be shared among employees.
  57. 57. PPE Required for Lab Entry  DLAM areas should have a sign posted on the door describing what PPE is necessary to be worn in order to access the room.  If a sign is not posted or if you are unsure of what PPE is required, contact your supervisor.
  58. 58. Eye and Face Protection  If you are exposed to flying particles, liquid chemicals, acids or caustic liquids, chemical gases or radiation then safety glasses, goggles or a face shield are required.  Sometimes eye and face protection may be required to be worn together (i.e. goggles & face shield).  Note: Contacts DO NOT protect the eye from injury!  The University has a prescription safety glasses program for employees that wear glasses. Contact EHS at (919) 962-5507 for further information
  59. 59. Hand Protection  Gloves should be worn to prevent contact with chemicals, cuts, abrasions, punctures or exposures to temperature extremes  Types of gloves:  Nitrile – used with acids  Latex – used with weak chemicals  Heat resistant – used in areas where autoclaving is conducted  Cryogenic – used for removing objects from ultra-cold freezers
  60. 60. Foot Protection  Foot protection is required if there is the potential in your job for injury to the foot due to:  falling or rolling objects  working around wet surfaces  working with large animals  electrical shock  objects that can pierce the sole of your shoe  The University policy is that anyone lifting more than 15 pounds is required to wear safety shoes.  The University will pay up to $80 for safety shoes in accordance with the Office of State Personnel.
  61. 61. Respiratory Protection  A surgical mask which is standard PPE in DLAM areas is not a respirator!  A respirator is worn to prevent exposure to harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors.  Wearing a respirator is a last resort and should never be a first line of defense.  Our first line of defense is to “engineer out” the need for a respirator. Thus, a respirator is required in areas where exposure cannot be fully controlled.  At UNC-CH we have a written respiratory program in place which offers the following:  Selection of respirators  Annual medical evaluation  Annual training  Annual fit testing
  62. 62. Respirator Use and Storage  Before each use, inspect your respirator for damage and defects and check for:  Tightness of connections  Condition of all parts  Face piece for pliable or deteriorated parts  After using be sure to clean it according to the manufacturers guidelines.  Store your respirator in a sealed bag or plastic container to protect it from:  Damage  Contamination  Dust  Sunlight  Extreme temperatures  Moisture  Chemicals
  63. 63. Noise  Excessive noise can damage your hearing and cause fatigue and stress.  Hearing protection should be used when working around loud noises for extended periods of time.  Our first line of defense is to evaluate the area to see if the noise can be “engineered out”.  Using engineering controls might include erecting sound barriers, insulating the equipment, or closing off the equipment entirely.
  64. 64. Hearing Conservation Program  The University has a Hearing Conservation Program (HCP) which requires annual training and annual audiometric testing to prevent the loss of hearing.  The OSHA standard requires anyone who is exposed to a noise level of 85 decibels or higher over an 8 time weighted average (TWA) hour period to be part of the HCP.  OSHA also requires the employer to provide training in the use of all hearing protectors provided to employees.  At UNC-CH the following hearing protectors are available:  Earplugs  Earmuffs  Ear Bands
  65. 65. High Noise Areas Within DLAM  Hearing protection may be needed when performing certain activities such as:  Working in cage wash areas  Working in dog run areas  Working with/around large animals  If you have concerns about noise levels in your area contact EHS at (919) 962-5507
  66. 66. How to Insert Earplugs  Ensure that hearing protection is properly used as improper use of hearing protection can reduce its effectiveness and put your hearing at risk.  Steps to take when donning (putting on) ear plugs:  Make sure your hands are clean. Dirt and moisture in your ear canal have the potential to cause an infection.  Compress the plug between your thumb and forefinger.  With the opposite hand, pull outer ear backward and upward, then insert plug as far into ear as possible.  Hold your finger against the plug until it starts to expand.  For preformed plugs, pull outer ear backward and upward. Insert plug by twisting and pushing until it fits snugly and you feel a vacuum-like seal.  When doffing (taking off) hearing protection, again be sure your hands are clean.
  67. 67. Animal allergies  Exposure to animals or animal products (dander, hair, scales, fur, saliva and body wastes) in the workplace can cause asthma and allergies.  DLAM employees have prolonged and close contact with animals on a daily basis and are at greater risk of developing animal allergies.  If you have a pre-existing animal allergy, disclose this on the animal handler form.  If you develop signs of an animal allergy, contact the UEOHC for an appointment.
  68. 68. Ergonomics  The goal of ergonomics is to find ways to arrange the workstation, work tools and work practices to minimize potential for musculoskeletal disorders.  Ergonomics is concerned with eliminating or minimizing the following “Ergonomic Stressors” found in routine tasks:  Force – High force tasks involve heavy exertion for the muscles involved.  Repetition – Performing the same movements over and over with little change in motions or muscles used.  Extreme/Awkward/Static Postures – Prolonged or repeated time spent holding joints in an awkward or fixed position.
  69. 69. Musculoskeletal Disorders  Musculoskeletal disorders are disorders of the muscles, nerves, tendons, ligaments, joints, cartilage and spinal discs.  Musculoskeletal disorders are gradual-onset injuries that usually occur after repeated micro-trauma to a specific body part. They may take weeks, months or years to develop and are often ignored in the beginning due to a slow onset of symptoms.  DLAM personnel may be at risk for developing musculoskeletal disorders during routine tasks such as:  Lifting feed bags  Adding and removing bedding material  Cleaning and stacking cages, bottle, etc.  Prolonged periods of standing/walking
  70. 70. Safe Lifting  Lifting incorrectly can increase your risk of developing a back injury.  If it looks heavy and awkward it probably is – ask someone to help you or use a mechanical lift.  Think about the distance and height to the destination before lifting.  Do not carry more than 30 pounds by yourself.  Get help for objects with a width 18 inches or greater.  If possible, break the load down and make several trips with more manageable loads.
  71. 71. Proper Lifting Technique  Feet shoulder width apart  Crouch don’t stoop  Get a good grip on the object  Keep the object close to your body  As you grip the load, keep your back straight, shoulders back and stick your buttocks out.  Let your legs push your body up slowly and smoothly, no jerking motions.
  72. 72. Lifting in Awkward Places  If you must lift or lower an object from a high place:  Stand on a platform instead of a ladder  Lift the load in smaller pieces if possible  Push the load to see how heavy and stable it is  Slide the load as close to yourself as possible before lifting up or down  Get help when needed to avoid injury
  73. 73. Lockout/Tagout  DLAM facilities contain equipment that may require general servicing or maintenance.  Workers performing service or maintenance on equipment may be exposed to injuries from the unexpected startup of the equipment.  The OSHA Lockout/Tagout standard requires workers to shutdown equipment, isolate it from its energy source(s), and perform lockout/tagout to prevent injuries while maintenance and servicing activities are being performed  For example, prior to working on cage wash equipment, employees should shut down the washer, turn off the main power supply and perform lockout/tagout.
  74. 74. Slips/Trips/Falls  DLAM employees should be alert for the following Slip/Trip/Fall hazards:  Wet floors  Pipes protruding from wall or floor areas  Missing floor drain covers  Dogs running free in dog run areas  Steps that do not have a slip resistant coating on them
  75. 75. Who Cleans Up Spills?  DLAM employees are capable of cleaning up the majority of small spills.  Control the spill area  Assess whether you can clean up the spill  Place waste in disposal containers and submit an online waste pickup form.  If the spill is large, a high hazard chemical or you are not comfortable cleaning it up contact EHS immediately at (919) 962-5507.  Call 911 if a large or high hazard spill occurs after 5:00pm or on the weekends.
  76. 76. Handling Cages with Chemical Hazards  In the course of research, laboratory animals may be dosed with toxic chemicals.  Use of all chemicals in animals must be documented in a protocol approved by the UNC Institutional Animal Care and Use Committee (IACUC).  The animals may excrete toxic chemicals or toxic metabolites of these chemicals, particularly during the first 48 hours after dosing.
  77. 77. Handling Cages with Chemical Hazards  Prior to dosing animals with toxic chemicals, research staff must communicate with the DLAM Facility Manager regarding dosing schedule, location of animals and chemical to be used.  When these dosed animals are returned to their cages, research staff will place Chemical Hazard- Incinerate Bedding cards (provided by DLAM) on each cage.  A Chemical Hazard sign will also be placed on the room door by the research staff.

  79. 79. Handling Cages with Chemical Hazards  All bedding used within 48 hours of dosing will be considered contaminated.  Cages with contaminated bedding must be changed in a ventilated cage changing station or a biological safety cabinet.
  80. 80. Handling Cages with Chemical Hazards  The Chemical Hazard-Incinerate Bedding card will be placed on the dirty cage when sent to cage wash. This will identify cages that need to be dumped separately into a bag that will be sent to the incinerator, instead of the landfill.
  81. 81. Handling Cages with Chemical Hazards  In addition to the usual PPE required in their cage wash area, all staff dumping this contaminated bedding must wear an N-95 (or better) respirator.  Respirator use requires medical clearance, fit testing and training.
  82. 82. Biohazard Waste  Biohazards are infectious microorganisms that can affect the health of humans.  Biohazard materials also include any equipment that was used such as syringes, pipettes and scalpel blades.  Biohazardous waste has to be autoclaved prior to disposal in the landfill  Autoclaving provides sterilization through super heated steam under pressure.  Autoclaving has the ability to destroy microorganisms rendering the waste harmless.
  83. 83. Cage Dumping  The dumping of animal cages has the potential to produce aerosols.  Cages should be dumped in front of the Biobubble at all times to capture aerosols.  The waste bin should be within 5 inches of the pre- filter of the Biobubble.
  84. 84. Biobubble Maintenance  The ventilation balloon in the back of the Biobubble must be fully inflated at all times when dumping cages.  A shrunken balloon indicates restricted airflow through the pre- filter.  The pre-filter must be cleaned after each dumping session or when the balloon indicates restricted airflow.  The Biobubble must be certified annually.
  85. 85. Broken Glass and Sharps  Non-contaminated or decontaminated glassware and sharps are placed in a plastic bag within a cardboard box.  The box should be labeled, “CAUTION, GLASS and SHARPS, NON-HAZARDOUS MATERIAL ONLY”  When ready to dispose, tape securely and place in dumpsters.  Sharp objects such as needles, scalpels, or razor blades are to be disposed of in metal cans and labeled appropriately.
  86. 86. Chemical Waste  Chemical waste is used, obsolete or unwanted chemicals such as:  Formalin  Alcohols  Expired pharmaceuticals  Batteries  Chemical waste should be disposed of by requesting a Chemical Waste Pickup online under the Chemical Disposal button on the EHS web site.  UNC-CH is concerned that chemicals not make their way into our creeks and rivers.  You should not pour chemicals, cleaners or mop water outside on the ground or into outside storm drains.  For mop water, the best practice is to pour it into sink drains or animal room floor drains which go directly into the sanitary sewer system.  If you see anyone pouring liquids down the storm drains please notify EHS at (919) 962-5507.
  87. 87. Other DLAM Training  Based on the facility you work in or the types of hazards you encounter during your work operations you might be required to take the following safety trainings:  Bloodborne Pathogen  Biosafety Level 2  Biosafety Level 3  Occupational Noise Exposure  Respiratory Protection  Supervisor Led Hazard Communication  Supervisor Led Personal Protective Equipment  Your supervisor or DLAM training coordinator will inform you if any of these are required for your specific job.
