5. Introduction
 Health:
A state of complete physical, mental, and
social well-being and not merely the absence
of disease or infirmity.
 Safety:
The state of being safe; freedom from the
occurrence or risk of injury, danger, or loss.
5

6. CONT,,
 Laboratory:
 A place, building or part of a building used for scientific and
related work that may be hazardous.
 The work conducted in a laboratory may include teaching or
learning, research, clinical or diagnostic testing and analysis.

7. LABORATORY HAZARDS
 Anything that may cause injury, harm or damage.
 The laboratory environment can be a hazardous place to work
 The hazards encountered in a laboratory are many and varied.
 May result in short term or long term health effects if individuals
are exposed to these hazards.
 Many workers are unaware of the potential hazards in their work
environment, which makes them more vulnerable to injury
7

8. CONT,,
 Laboratory hazards may generally are
 Biological - eg pathogenic microorganisms, animals, biological
tissues, blood and other body fluids (human and animal)
 Chemical - eg corrosive, flammable, toxic substances
 Physical hazards – eg ergonomic hazards associated with manual
material handling and equipment use, handling sharps
 Electrical/Mechanical - eg high voltage apparatus, machinery
with moving parts
8

9. Laboratory Safety
 Laboratory safety rules and safe work practices or standard
operating procedures (SOPs) should be established by Faculties,
Schools and Disciplines to meet specific operational needs and to
reduce the risks associated with laboratory hazards.
 As a condition of entry to a laboratory, all individuals must
complete a laboratory safety induction and receive specific training
in local safety rules and laboratory procedures relating to their
work (including relevant SOPs).
 Individuals are required to comply with laboratory safety rules and
procedures at all times whilst in the laboratory. Individuals who act
contrary to the rules and procedures should be excluded from the
laboratory.

10. Personal Protective Equipment (PPE)
 The department or laboratory shall provide PPE to each staff
member.
 The laboratory supervisor must determine the appropriate
PPE needed for procedures in the lab by conducting.
 Eye protection
 Respiratory protection
 Clothing
 Hand protection
 Chemical handling
10
 Food and drink
 Accidents and injuries
 Heating substances
 Sharps
 Fume Hoods and Other
Engineering Controls

11. Eye Protection
 Eye injuries are horrifying, but preventable
events.
 Wisconsin law requires eye protection for all
laboratory workers, so no one should work or be
inside a laboratory without proper eye protection.
 Be aware of the hazards of contact lenses. They
are difficult to remove if your eyes must be
washed in an emergency.
11

12. Respiratory Protection
 The Occupational Safety and
Health Administration (OSHA)
has strict requirements for
respirator (e.g., full-face mask or
N-95 filter mask) use.
 Always work in a well-ventilated
area.
12

13. Clothing
 Wear clothing that protects your skin.
 Shoes should completely cover your feet.
 Use a lab coat for further protection. The coat
sleeves keep splashes, aerosols and dusts from
touching your forearm and wrist.
 Long hair, dangling jewelry, and loose or
baggy clothing are a hazard in the laboratory.
13

14. Hand Protection
14
 Vinyl and latex gloves should be a common sight in all
laboratories.
 They are inexpensive, comfortable and provide a nominal barrier
to common hazards.
 Check them for holes and change them frequently.
 Be aware that vinyl and latex gloves offer no protection from
many corrosives and organic solvents.

15. HANDLING CHEMICALS
 All chemicals in the laboratory are to be
considered dangerous.
 Avoid handling chemicals with fingers.
Always use a tweezer.
 When making an observation, keep at
least 1 foot away from the specimen.
 Do not taste, or smell any chemicals.
 Never return unused chemicals to their
original container.
15

16. Food and Drink
16
 Food and drink should not be stored or
consumed in areas where chemical, biological or
radioactive substances are being used or stored.
 Laboratory refrigerators and cold rooms may
not be used for the storage of foods.

17. ACCIDENTS AND INJURIES
 Report any accident (spill, breakage, etc.)
or injury (cut, burn, etc.) to the teacher
immediately, no matter how trivial it
seems. Do not panic.
 If a chemical should splash in your eye(s)
or on your skin, immediately flush with
running water for at least 20 minutes.
17

18. HEATING SUBSTANCES
18
 Take care that hair, clothing, and hands are a
safe distance from the hot plate at all times.
 Heated glassware remain very hot for a long
time. They should be set aside in a
designated place to cool, and picked up with
caution.
 Never look into a container that is being
heated.
 Do not place hot apparatus directly on the
laboratory desk. Always use an insulated
pad.
 Allow plenty of time for hot apparatus to
cool before touching it.

19. SHARPS
 Sharps (needles, broken glass, scalpels,
razor blades, etc.) must not be disposed
in the regular waste stream.
 Needles and scalpels must be placed in
red plastic “sharps” boxes and disposed
of as biomedical waste, no matter if they
are contaminated with a biological
substance or not.
 Syringes must be disposed of in the red
sharps box for biomedical waste
disposal whether or not they are
contaminated.
19

20. FUME HOODS AND OTHER
ENGINEERING CONTROLS
 Examples of engineering
controls include chemical
fume hoods, glove boxes
and remote automation
that keeps a worker away
from a dangerous process.
 A fume hood must have an
adequate face velocity
(measured at the work
opening) to ensure the
proper removal of toxic
materials
20

21. SAFETY EQUIPMENT
 Maintain all safety related equipment and information
clearly labeled and stored in the same area so it can be
easily found in an emergency.
 First Aid Kits
 Spill Kits
