1. Safety in Biological Sciences
Laboratories
For newcomers, the
laboratory may at first
seem like a maze with a
myriad of things to
learn, safety
procedures to follow,
rules to be obeyed,
hazards to contend
with, new safety
equipment to use, etc,
etc ..
This presentation will
introduce you to such
procedures.

2. Safety in Biological Sciences
Laboratories
It is important to
remember and
comply with these
safety instructions.
Students not
working according
to these precautions
may be asked to
leave the lab.

3. General Safety Precautions
Protective clothing
All students must wear
a lab coat during lab
sessions
Leave the lab coat in
the room if you must
leave the lab before its
completion
Gloves or bandaids will
be available if required
Wear goggles if risk of
splash

4. General Precautions
It is important to wash hands
thoroughly before leaving the lab or
if you have spilled on your hands

5. General Precautions
Spills
Report all spills to the lab instructor, whether
they are on the bench, floor, equipment or on
your person

6. General Safety Precautions
Disposal
Ensure you have disposed
of wastes in appropriate
containers
Biohazardous material: red
autoclave bags
Biohazardous sharps
(anything that may puncture a
bag): yellow sharps containers
Ensure broken non
contaminated glassware is
disposed of in proper
containers

7. General Safety Precautions
No eating or drinking

8. General Safety Precautions
Familiarize yourself with the location

Safety showers
Fire extinguishers
Eye wash stations
Fire alarms
Electrical shutoff (not in all rooms)

9. General Safety Precautions
Familiarize yourself with the location
and proper use of:
Gas shutoff
Spill kits
MSDS (material safety data sheets)
Familiarize yourself with the procedure
for emergency drill, evacuation and
meeting area outside

10. WHMIS for Biology Students
WHMIS
Workplace Hazardous Materials Information
System
Federal legislation to protect workers by
supplying information about hazardous
materials they may be using
Goal is to reduce injury and disease by
communicating specific health and safety
information that can be used to reduce
exposure to hazardous materials

11. WHMIS Hazard Classifications
Class A: Compressed Gas
Class B: Flammable & Combustible

Class C: Oxidizing Material
Class D: Poisonous & Infectious Material

12. WHMIS Hazard Classifications
Class E: Corrosive Material
Class F: Dangerously Reactive
Material

13. Material Safety Data Sheets
(MSDSs)
provides specific hazard information, safe handling
information, and emergency procedures for a
controlled product.
Key source of information for developing safe
working procedures.
Accessed online at TRU
Bookmarked on all Biology computers
ThompsonMSDS
Msds
Read before using new chemicals

14. MSDSs Provide
1. Product Information
2. Hazardous Ingredients
3. Physical Data
4. Fire and Explosion Hazard
5. Reactivity Data
6. Toxicological Properties
7. Preventative Measures
8. First Aid Measures
9. Preparation Information

15. Safe Handling Instructions
In addition to WHMIS classification
workplace labels must include safe
handling information and personal
protective clothing and equipment
required
This information may be written or
included as symbols

16. Acetone Workplace Label
Keep away from heat, sparks, and
flames
Wear safety goggles and butyl rubber
gloves
Use in fumehood
MSDS available
