Laboratory
Safety Program is an "Occupational Exposure to Hazardous Chemicals which
requires that facilities engaged in laboratory use of hazardous chemicals
develop and implement a written "Chemical Hygiene Plan". The plan
must set forth procedures, equipment, personal protective equipment (PPE), work
practices, and policies. These must be implemented and used to protect
employees and students from the potential health hazards presented by use of
hazardous chemicals used in laboratories.
Initial
training and annual refresher training thereafter is required for all employees
who work in chemical utilizing laboratories. Laboratory safety training will
vary from year to year depending upon necessity of emphasis as the need arise.
This can be the following:
a.
Material
Safety Data Sheets (MSDS) Requirements
b.
Orphaned
Chemicals
c.
Chemical
Spills/Spill Clean Up
d.
Hazardous
Waste (Shipment and Disposal)
e.

Maintenance
The
following are minimum laboratory essential criteria:
- Emergency Phone Numbers
Must
be clearly and visibly posted adjacent to lab phones. Emergency phone numbers
and emergency procedures must also be posted.
b.
Appropriate Warning Signs Posted
i.
Warning
signs must be posted outside of the laboratory for use by firefighters in
emergency conditions and the names and telephone numbers of responsible
laboratory personnel.
ii.
Laboratories
that utilize radioactive materials must also be posted with radiation warnings.
iii.
Researchers
working with or storing biosafety level 2 or higher organisms should also label
the laboratory with the universal biohazard warnings.
c.
Food or Drink Rules
i.
No
food or drink is allowed in any laboratory.
ii.
Application
of cosmetics in a laboratory is prohibited.
iii.
Smoking
is prohibited in laboratories and in all buildings that house laboratories.
iv.
Ice
in the ice machines in science/research facilities is not safe for human
consumption and is placarded as such.
d.
Material Safety Data Sheets (MSDS)
MSDS
must be on hand or on order for all chemicals within the lab. They should be
maintained in a single binder or location, and be available to all employees
within the lab, and for individuals reviewing lab safety procedures.
e.
Ventilation of Laboratories
i.
Laboratories
must be areas of controlled occupational exposure regarding indoor air quality.
ii.
Fume
hoods or bio safety cabinets are to be utilized as controlled areas for
applicable experimentation.
iii.
Laboratories
must be maintained under negative air conditions.
f.
Fire Extinguishers
i.
Fire
extinguishers must be charged and inspected.
g.
Paths Of Egress
i.
It
is imperative that all laboratories have unobstructed means of egress.
h.
Electrical/Gas Safety Issues
i.
Electrical
1.
Electrical
cords must be of good condition. Repair with electricians’ tape is not
acceptable.
2.
Cheater
plugs are not authorized.
3.
Access
to electrical sources must be kept clear of obstructions.
4.
There
must be no visible overloading of electrical circuits.
5. All electrical equipment must
be appropriately
ii.
Gas
1.
Bunsen
burners and burner tubing must be routinely inspected and free of defects.
2.
Access
to gas shut offs must be kept free of obstructions.
i.
Compressed Gas Cylinders
Compressed
Gas Cylinders must be appropriately secured. All compressed gas cylinders
inclusive of lecture bottles, EMPTY CYLINDERS, and cylinders in transit, must
be secured. Cylinders are appropriately secured by a number of means including
clamps and straps, chains, straps, stands, racks, and any acceptable means that
eliminates the possibility of tipping over of a tank.
j.
Personal Protective Equipment (PPE)
i.
The
individual responsible for the laboratory is also responsible for insuring that
adequate PPE is on hand and in good condition for use by lab workers.
ii.
PPE
will include at minimum, but not be limited to:
- Gloves appropriate for type of
research conducted
- Lab coats/aprons (as required)
- Safety glasses/goggles and face
shields as required
- Long sleeved clothing and long
trousers/slacks to cover as much skin as possible is encouraged.
- Short pants/short skirts are
prohibited.
- Open toed shoes/sandals are
prohibited. Solid rubber soled shoes are encouraged.
l.
Machine Guarding
Machines
and equipment with rotating gears, belts, and or functions that may allow
entrapment of fingers, hair, clothing, etc. must be guarded.
m.
Proper Labeling of Chemicals
All
chemicals in laboratories must be labeled with hazard information inclusive of
chemical nomenclature, physical and health hazard information and manufacturer.
n.
Segregation of Chemicals
Stored
chemicals must be separated and stored based upon compatibility and reactivity.
(i.e. separate acids from bases, flammables from oxidizers, and reactives from
air or water).
o.
Refrigerator Storage
i. Do not store flammables in refrigerators.
ii. Explosion proof and flammable refrigerators
and/or freezers are to be utilized only for the intended purpose stated by the
manufacturer.
p.
Physical Storage of Chemicals
i. Do not store chemicals on shelves above eye
level.
ii. Do not store chemicals in fume hoods as bulk
storage in hoods impedes airflow.
iii. Store flammables in flammable storage
cabinets.
iv. Do not store chemicals or chemical waste on
floors unless they are in secondary containment.
v. Avoid storing chemicals in direct exposure to
sunlight, excessive heat, or excessive cold.
q.
Chemical Waste
i. Ensure that all chemical waste containers
are kept closed, appropriately marked and labeled to include start date of
collection.
ii. Outdated, expired, and/or unknown chemicals
must be disposed of as waste through coordination with the Chemical
Coordinator, EH&S.
iii. Chemicals that may no longer be used, or of
questionable purity, or that are past expiration date should be removed from
the labs.
r.
Biological Waste
Common
methods for appropriate disposal include disinfecting, autoclaving, and for
liquid disposal in the sanitary sewer. Be sure that the container is properly
labeled, and decontaminated before disposal. Note the method of disposal for
each liquid and solid waste. Observe that biohazard waste is stored in
secondary containment.
s.
Sharps Disposal
Contaminated
sharps include needles, syringes, scalpels, exposed dental wires, broken glass
if contaminated with human blood, and other potentially infectious material(s).
These items must be collected in a sharps container of other puncture resistant
container that is color coded or labeled with the universal biohazard symbol.
