• Act effectively in an emergency
3. What You Need to Know
• MU Chemical Hygiene Plan
• Required PPE
• Safe work practices
• Emergency response
4. Chemical Hygiene Plan
• Chemical hazards
• Safe work practices, procedures, and controls
• Proper PPE to use with specific chemicals
• Emergency procedures
5. Chemical Hygiene Plan (cont.)
OSHA requires MU to:
• Evaluate control equipment and perform annual
laboratory inspections
• Establish standard operating procedures
• Perform exposure assessments
• Provide medical consultations and exams to
Faculty and Staff
• Provide proper training
• Manage safety information
6. MSDS and Labels
The MSDS tells you:
• Physical and chemical
properties
• Health hazard information
• PELs and symptoms of
exposure
• How to safely handle
substances
• First aid and treatment for
overexposure
8. Health Hazards: Chemicals
• Short-term health effects
• dizziness, nausea, and
headache, irritation to the
eyes, nose, throat, or upper
respiratory tract; persistent
cough, wheezing, or tightness in the
chest; chest pain; and difficulty
breathing or shortness of breath
• Long-term health effects
• internal organ damage, reproductive
problems, and cancer
9. Hazards
• Do you understand the
information that has been
presented so far?
10. Chemical Fume Hoods
Chemical fume hoods serve
three functions:
• Isolate chemicals and
apparatus that present
physical hazards
• Contain spills
• Control inhalation
exposure
Use a hood for operations
that require it’s use based
on the chemicals MSDS
11. Chemical Fume Hoods (cont.)
When using a hood:
• Confirm that it is working properly
• Keep chemicals and lab equipment 6 inches
inside
• Keep glass door between your face and
materials
• Avoid swift hand or body movements
• Make sure items don’t block air flow
12. Required PPE for Eyes
• Eye protection
• ANSI – Z87 Approved
Laboratory Chemical Splash
Goggles are required for all
laboratory classes where
chemicals are present.
• Laboratory Goggles are
available for purchase in the
campus bookstore
• NO COMMUNAL USE
GOGGLES ARE AVAILABLE
IN LABS
13. Required PPE (cont.)
• Gloves
• MU Chemical Hygiene Plan
will list what type of gloves
to use for certain chemicals.
• Most laboratories on
campus will allow for
general Latex or Nitrile
gloves
• Other skin protection
• Respirators
• SEE EHS before using!
• Footwear
14. Safe Hygiene
ALWAYS:
• Wash your hands after direct exposure and
before leaving the lab
NEVER:
• Smell or taste chemicals
• Eat, drink, chew gum, smoke, or apply
cosmetics near chemicals
• Store food in chemical storage refrigerators
• Use lab equipment to handle food
15. Laboratory Equipment
• Glassware
• Electrical equipment
• Hot Plates
• Stir Plates
• Equipment with moving
parts
• Compressed gas
cylinders
16. Chemical Storage: Basic Segregation
• First, segregate by state:
solids, liquids, and gases
• Then segregate by hazard
class
• Never store chemicals
alphabetically
• Date incoming containers
of chemicals with a specific
shelf life
17. Chemical Storage: Where to Store
• Volatile toxic or odiferous chemicals in a vented
cabinet
• Flammable solvents in a flammable storage
cabinet, under a fume hood, or in a safety can
• Highly reactives in locked cabinets Corrosives in
cabinets or under fume hoods on trays
• Solids on shelves or in a cabinet
• Gas cylinders secured close to area of use
18. Safe Housekeeping
• Keep surfaces
clean, dry, and uncluttered
• You are responsible for
keeping your lab space clean!
• Never store chemicals on
the floor
• Never store chemicals
open to the air
• Be sure to have clear
access to emergency exits
and equipment
19. Inspections
• MU EHS conducts regular lab inspections
• Correct and document safety problems
• Include:
• Emergency equipment
• Chemical storage areas
– Satellite Accumulation Areas
• Chemical fume hoods
• Electrical equipment
• Compressed gas cylinders
• Emergency exits
20. Controls, PPE, and Safe Work Practices
• Do you understand the
information presented
about engineering
controls, PPE, and safe
work practices?
21. Basic First Aid
• Chemicals in eyes
• Chemicals on body
• Inhalation
• Swallowing
22. Basic First Aid (cont.)
• Know where eyewash
stations and emergency
showers are located
• Notify your instructor
immediately if contaminated
• If required Call 911
• After calling 911 contact MU
Police and Public Safety x7577
• Get medical attention after
washing off chemicals
23. Spill Control: Minor Spills
• Alert people in the immediate area
• Increase ventilation
Using the MU Chemical Spill Kit
• Don PPE
• Absorb spill with kit absorbents
• Collect residual chemical and cleanup materials
in sealed black bags for disposal
• Clean spill area with water only
24. Spill Control: Major Spills
• Alert everyone in the area to evacuate
• Attend to injured or contaminated co-workers or
students and remove them from the area
• If chemical is flammable, turn off ignition
sources, if you can do so safely
• Evacuate, closing doors as you exit
• Contact emergency response team
• Methodist University Police and Public Safety x7577
25. Fire Emergencies
• Activate alarm and call
911 then x7577
• Notify everyone around
• Shut down equipment, if
safe
• Use a fire extinguisher, if
appropriate
• Isolate the area by
closing doors and
windows
• Evacuate
26. Key Points to Remember
Remember these four basic principles of laboratory
safety:
• Familiarize yourself with the MU Chemical
Hygiene Plan
• Select appropriate PPE
• Maintain a safe laboratory environment
• Prepare for emergencies
