16. How can I be infected at work?
• Contact between mucous membranes and
infected blood or body fluids (eyes, nose, or
mouth)
• Contact between broken or damaged skin and
infected blood or body fluids
• Injury with a contaminated needle or sharp
17. Always Use Universal Precautions
OSHA defines universal precautions as an
approach to infection control in which all human
blood and certain body fluids are treated as if
known to be infectious for bloodborne
pathogens
18. Handling Sharps
• Always point sharps away from yourself and others
• Do NOT bend, break, shear off, or attempt to recap needles into the sheath
• Sharps must be disposed of in an appropriate sharps container
– Made of heavy duty plastic
– Able to be closed with a tight fitting, puncture resistant lid that does not allow sharps to
come out
– Upright and stable during use
– Leak resistant
– Properly labeled outside to warn of sharps/hazardous contents
• Do not overfill sharps container (no more than ~ ¾ full)
• If you have contaminated broken glass, do NOT use your hands to pick up,
use a broom and dustpan for disposal
• Request pickup of full container through EHS website
19. Sharps with safety features
When possible, use devices with safety controls built in, such as syringes with
Luer lock fittings.
Retractable needle system
Luer-lock systems
20. If no alternative to recapping or removal of the needle is
possible, a one-handed technique or mechanical device must be
used and justified to the Institutional Biosafety Committee
One-handed
technique
21. Engineering Control:
Biosafety Cabinets (BSC’s)
• Provides laminar/directed air flow, creating an air curtain behind the sash
• VERY IMPORTANT not to block airflow and to work behind the curtain (~6”
behind sash)
• Class II provides personnel, environmental, and product protection
• Must be certified annually or whenever moved
22. Clean Air Bench (not appropriate)
• Directed airflow TOWARD the
user
• Provides only product
protection
DO NOT USE WITH
INFECTIOUS MATERIAL
23. Personal Protective Equipment (PPE)
Always wear appropriate PPE, which, at a minimum, includes:
• Gloves when hand contact is expected
• Protective clothing (laboratory coat) when the potential for
splattering body fluids exists
• Eye protection when the potential for splashes or sprays exist
General rules for using PPE:
• Make sure it fits properly
• Check for damage before use
• If damaged during use, remove and replace immediately
• Do not wear sandals or perforated shoes
• Remove PPE when leaving the laboratory
24. Gloves
• Glove selection should be based on resistance to the materials you
are working with
• They are intended for incidental contact, not extended contact. If
extended contact with a hazardous material is anticipated, consider
thicker reusable, purpose-specific gloves
• Gloves frequently used in labs are disposable (thin, sold in boxes,
for single use). Some lab operations require use of thicker reusable
gloves (cryogenic, heat-resistant, cut-resistant, etc)
• Do NOT reuse thin single-use gloves. Do not blow on them to
reinflate, twirl around rapidly to reinflate, pull on the potentially
contaminated outside to reinflate, wash and dry to use again
• Dispose of all used disposable gloves in a biohazard box
25. When not to wear your PPE
• In the lunchroom
• In the bathroom
• Using your office
computer
• Using your cellphone
• On the UM shuttle
26. What about between lab spaces?
If you are moving materials or equipment between labs or
buildings,
• Where possible, use secondary containment like a bucket
• “one glove policy”- one glove on to hold the material, one
ungloved hand to open doors, push elevator buttons, etc.
• If you cannot hold the material in one hand, use a cart and/or
request help from a lab mate
27. Work Practice Controls
• Wash your hands immediately after removing your gloves
• Do not eat, drink or apply cosmetics in the laboratory
• Follow University guidelines for disposing of biomedical waste
• Maintain the laboratory in a clean and orderly manner
• Promptly clean-up spills of biological material
• All procedures involving blood or OPIM must be performed in
a manner that minimizes spraying, splattering or generation of
aerosols
28. Labeling and Waste
Equipment, containers, and waste must be
properly labeled; this includes
• Containers of regulated waste
• Refrigerators & freezers
• Containers used to store, transport or ship blood or
OPIM
• Centrifuges
• Any potentially contaminated waste should be
disposed of through the special medical waste
stream at UMB EHS; biohazard boxes and bags
are provided by request at 6-7055 or on the EHS
website
• No chemical, radioactive, or liquid waste should
be placed in the biological waste disposal
containers
29. Decontamination
Anything that comes in contact with blood or OPIM must be
decontaminated or sterilized before next use or in the event of a
spill. Always wear appropriate PPE when cleaning up.
Use a 1:10 dilution of household bleach, let stand for at least 10
minutes, then clean off with water or 70% ethanol. An EPA-
approved disinfectant may also be used.
(https://www.epa.gov/pesticide-registration/selected-epa-registered-disinfectants )
30. What to do if you have an exposure
• Stop work immediately, inform others in your area
• If a splash or spill: Wash exposed area with soap and water for
15 minutes; irrigate mucous membranes with water for 15
minutes
• Seek medical care if needed.
During business hours, on or near campus
UMB Immediate Care (UMIC) 408 W. Lombard St., (667)214-1899,
Open M-F 7am to 5pm.
After hours, seek attention from the UMMC Emergency Room,
your personal physician, or a local hospital
• Report the incident to your supervisor/sponsor and EHS ASAP,
but do not delay medical treatment if needed
In an emergency, call 911 (campus phone campus police;
personal phone Baltimore police)
31. Institutional Biosafety Committee (IBC)
Any work with any human materials (including human cell
lines)/recombinant DNA/viruses must be registered with the IBC.
All personnel working on these materials must also be listed.
Does my research need to be registered with the IBC? Contact
EHS at 6-7055, we’ll let you know!
How do I submit a protocol? Use the CICERO research
evaluation portal at https://cicero.umaryland.edu
Note for ANIMAL work: please be aware that the IACUC will not
approve your protocol until you have received IBC approval

These elements are summarized in the University CHP, available online, which includes:
35. The GHS
As of March 2012, the U.S. adopted the UN’s Globally
Harmonized System of Classification and Labeling of Chemicals
(GHS). Subsequently, OSHA revised the Hazard Communication
Standard (HCS) to align with the majority of the elements of the
GHS.
The GHS is an internationally standardized approach to hazard
communication that provides a harmonized system of
classification and labeling and revised organization of safety data
sheets (SDSs).
36. What does this mean to you?
Three main areas of standardization:
• Classification of hazards
• Labeling requirements
• Safety data sheets
37. GHS Labeling
Chemicals will now be labeled using the following
elements when applicable:
• Pictograms (9) – graphic element encompassed by a red
diamond
• Signal Words – “Danger” or “Warning” to signify relative
severity of the hazard
• Hazard Statements – to describe the nature and degree of the
hazard
• Precautionary Statements - to describe recommended
measures to minimize or prevent adverse events

• Ethylene glycol
• Ethers such as diethyl ether and
tetrahydrofuran
• Acetone
• Ethyl acetate and butyl acetate
48. Handling flammable liquids
• Keep away from sources of ignition
• Refrigerators used to store flammables
must be explosion proof
• Cold rooms are not appropriate
storage locations for flammable liquids
• Should be stored in a flammable
storage cabinet
49. Oxidizers
• Oxidizers are chemicals that support
combustion
• Oxidizers should never be stored with
flammable liquids
• Examples include
– Oxygen, chlorine, peroxides, nitric acid,
perchlorates, and permanganates
50. Cryogens
• Cryogens are chemicals that have temperatures
below NEGATIVE 100oF. Examples include helium and
nitrogen
• Can cause severe damage to your skin or eyes
• Wear gloves designed for working with cryogens and
a face shield
51. Peroxide-Forming Chemicals
• Can be an explosive hazard
• Examples include:
– Diethyl Ether
– Tetrahydrofuran
• Should be dated upon receipt and opening, stored away from
light, heat, and contact with atmospheric oxygen
• Should be disposed of within 6 months of opening or by the
expiry date, whichever comes first
If you use peroxide-forming chemicals in your lab,
please take EHS training on Working with Reactive
Chemicals
52. Formaldehyde

• Valve protection caps should be installed on cylinders at all times
when not in use
• NEVER stick anything into the cylinder cap holes in an attempt to
loosen the cap
• Use an adjustable strap wrench to remove stuck caps
• If the cap is still difficult to remove, attach a tag or label to the
cylinder identifying the problem and return the cylinder to the
supplier
• Report a leaking cylinder
• CO2 and N2 are oxygen displacers- do not use in confined spaces,
ensure adequate ventilation
• N2 is a cryogen
• O2 is an oxidizer (will make other material more likely to explode or
react)
55. Engineering Control: Fume hoods
• Used for chemical work
• Do not store material in a fumehood
• Tested annually by EHS
– If fume hood fails testing, remove all
materials from the hood, discontinue use,

signed, with emergency contact information, and appropriate
hazard symbols
New or updated door signs may be requested for free at MyEHS
58. Labeling Chemical Containers
• Anytime you transfer a chemical into a separate container, the
new container must be labeled with the full name and
percentage of all components and any hazard information
associated
• Ensure that labels on chemicals are not removed or become
illegible
59. General Good Practices when
Working with Chemicals
• Read and understand the University CHP
• Learn about chemical hazards associated with your research
by looking up the SDS

68. What is Hazardous Waste?
Resource Conservation and Recovery Act (RCRA),
regulated by the US Environmental Protection Agency
(EPA)
• defines hazardous waste as any waste that exhibits at least
one of four hazardous characteristics or appears on one of
the four hazardous wastes lists
• Generally applied to “solid wastes”, which has a very broad
definition, so consider most chemical waste generated in your
lab to fall under this regulation
69. Four Characteristics and Four Lists
Characteristics:
• ignitable
• corrosive
• reactive
• toxic
Lists:
• P and U list: Hazardous waste
from pure or commercial grade
chemical products; P is “acute”
hazardous waste – generated in
labs
• F and K list: Hazardous waste
from manufacturing or industrial
processes, where K generated
from specific processes and F
from non-specific – not
generated in labs
70. Characteristic: Ignitable
• A liquid that has a flash point of less than 60oC (140oF),
• Non-liquids capable of causing fire through friction,
absorption or moisture, or spontaneously changes and
when ignited burns so vigorously and persistently that
it creates a hazard,
• An ignitable compressed gas, or
• An oxidizer
Note that some aqueous solutions (at least 50% water by
weight) that have less than 24% alcohol content lose their
ignitability designation by EPA standards so do not need to
be sent to EHS
72. Characteristic: Corrosive
• Aqueous or liquid wastes with a pH
less than or equal to 2 or greater
than or equal to 12.5; or
• Liquid that corrodes steel at a rate
greater that 6.35 mm per year at
55oC
74. Characteristic: Reactive
Materials that, under normal conditions,
are:
• Unstable and readily undergo violent
change;
• React violently with water;
• May give off toxic gases; or
• May be capable of detonation or
explosion
75. Examples of Reactive Wastes
• Butyl Lithium
• Lithium Aluminum Hydride
• Potassium Cyanide
• Nitrophenylhydrazine
• Sodium metal
• A cyanide or sulfide bearing
waste which when exposed to
pH conditions between 2 and
12.5 can generate toxic gases,
vapors or fumes
76. Characteristic: Toxic
• One of 41 chemicals in a
concentration equal to or
greater than the respective
value listed in 40 CFR 261.24
• 8 metals (As, Ba, Cd, Cr, Hg,
Pb, Se, Ag)
• 33 herbicides, pesticides,
other organics
77. Examples of Toxic Wastes
• Paint wastes containing lead, chromium or
silver
• Mercury waste from dental amalgams
• Silver waste from x-ray processing equipment
• Chloroform
78. P & U Listed Wastes
Many of the chemicals used in University research labs may fall
under the P or U-listed waste categories, as discarded
Commercial Chemical Products
Examples include:
• Osmium Tetroxide (P)
• Cyanide salts (P)
• Sodium Azide (P)
• Phenol (P)
• Nitrophenol (U)
• Acrylamide (U)
• Lead Acetate (U)
• Tetrahydrofuran (U)
79. Waste Mixtures
The EPA also regulates waste mixtures, which are
defined as:
• A mixture of a non hazardous solid waste and one
or more listed hazardous wastes
• A mixture of a non hazardous solid waste and one
or more characteristic hazardous wastes, unless
the mixture does not exhibit any of the hazardous
waste characteristics
80. Hazardous Waste Accumulation
Requirements
Hazardous Waste may be accumulated at the site of generation
until either…
• 55 gallons of hazardous waste are accumulated; or
• 1 quart (~1L) of acutely hazardous waste (P-listed) are
accumulated
81. Hazardous Waste Accumulation
Requirements
• All waste generated in the laboratories must be under the control of the
operator of the process generating the waste.
• Waste containers must be at or near the process generating the waste.
• Incompatible wastes cannot be placed into the same container if the
placement could lead to a hazardous chemical reaction
• Containers holding hazardous waste must be kept closed except when it is
necessary to add or remove waste.
• Containers must be managed to avoid releases
• Do not completely fill containers
• Keep ignitable and reactive wastes away from ignition sources
• Use secondary containment as required
82. Hazardous Waste Labeling
Any container used to contain or accumulate hazardous waste
MUST be labeled with:
• The words “Hazardous Waste”
• The date waste was initially added to the container
• All chemical constituents and their concentrations (% by weight,
add up to 100%)
• no abbreviations, chemical formulas, or trade names
• written in English
84. Containers to hold Hazardous Waste
Commercial containers may be reused to hold hazardous waste
if:
• The container is in good condition;
• Waste placed into a container is compatible with the container;
• The original label has been completely obscured or removed; AND
• The original container did not contain a P-listed waste
EHS can also provide hazardous waste
containers (plastic only)- call 6-7055 or
request on the chemical waste removal
online form
85. How to Dispose of Waste
Submit a request for hazardous waste removal from
EHS at
http://www.umaryland.edu/ehs/
Waste will be removed within three working days
86. Special Instructions for Removal
• Make sure to include both building name and room
number on your request form
• Do not place hazardous waste in areas accessible to
the general public, in the general trash or an area
where it may be mistaken for trash
• Segregate hazardous waste from chemicals in use, in
a safe but conspicuous location
87. Special note: Unknown Waste
Without an accurate description, chemicals can not be
disposed of in a safe manner.
• Analysis of unknowns can cost several hundred
dollars.
• EHS does reserve the right to institute a charge-back
program for the charges associated with the analysis.
To prevent costly analysis, always make sure all
containers in your lab are appropriately labeled
88. Special note: Ethidium Bromide (EtBr)
While EtBr is not regulated by the EPA, the
University does handle disposal as though it is
regulated
• Turn contaminated aqueous solutions into EHS for
disposal
• For contaminated solid gels, they can be disposed of
in the red biohazard bags, to be collected by EHS
89. Special note: Broken Glass
• EHS does not provide broken glass boxes;
they can be purchased from multiple
vendors
• Do NOT use Biohazard boxes for broken
glassware
• Do not dispose of special medical waste or
biohazards in broken glass boxes as they
enter the regular waste stream
90. Special note: Empty chemical bottles
In general, empty chemical containers that are not
broken may be disposed of through regular
housekeeping streams, provided:
• They are completely empty
• All labels have been obscured and can no longer be read
• They do not contain any potential biohazards
• They never contained an acutely toxic chemical (P-list)
91. University Policy on Waste Minimization
The reduction to the extent feasible, of hazardous wastes generated
prior to treatment, storage, and disposal, through any source
reduction or recycling activity that results in
• reduction of the total volume of hazardous waste, or
• reduction of the toxicity of the hazardous waste.
What this means to you?
• Consider if your research activity can be performed without
generation of hazardous waste
• Only purchase what you need for your work for a reasonable
amount of time
92. University Policy on Pollution Prevention
Relates to the use of raw materials, processes, or practices that reduce
or eliminate the creation of pollutants or wastes at the source,
including practices that reduce the use of hazardous and non-
hazardous materials, energy, water, or other resources as well as those
that protect natural resources through conservation or more efficient
use.
What this means to you?
• Consider if your research activity can be performed without the use
of materials that may pollute or cause waste streams to the
environment
• Use your resources efficiently and make sure you dispose of
materials appropriately to reduce impact on the environment
93. Chemical Spill Response
For small spills:
• Notify others in your area of the spill
• Leave the room and close the door to control
access
• Wear appropriate PPE (eye protection, lab coat,
gloves, respirator if needed)
• Control the source of the spill
• Control the spread of the spill
• Absorb any free standing liquid that has spread
behind or under equipment
• Dispose of any spill debris and clean up material
as hazardous waste
• Restock spill response supplies
If anyone is injured
CALL 911
94. Special Medical Waste Disposal
Special Medical Waste (SMW) is defined as :
• Cultures and stocks of infectious agents and associated biologicals, or
• Human pathological waste including tissues, organs and body parts
and body fluids and specimens of body fluids and their containers
• Human blood and blood products including items saturated and/or
dripping with human blood and their containers (intravenous bags)
• Sharps that have been used in animal or patient care or treatment
and broken or unbroken glassware that were in contact with infectious
agents (slides and cover slips)
95. Special Medical Waste Disposal
• Sharps must be placed into a puncture
resistant sharps container
