1. “Never trust an atom; they make up everything.” 

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 or apron.
Gloves will be available if required.
(Wear goggles if risk of splash. )

5. General Precautions
It is important to wash hands thoroughly before leaving the lab or if you have spilled on your hands.
Best way to prevent spread of infectious disease and cross contamination from lab to other areas or persons

6. General Precautions Spills
Report all spills to the teacher, whether they are on the bench, floor, equipment or on your person.
Very important to notify if anything is spilled so appropriate cleanup can occur. (acids or bases need to be neutralized to avoid burning others, solvents may cause fires if a burner is lit etc.)

7. General Safety Precautions
Disposal

No eating or drinking in the lab.
Suitable footwear: no open toes or heels.
Keep fingers and objects away from your mouth and eyes.
Important to report injures so proper medical action is taken if required
Fingers pens etc near eyes may result is spread of biohazardous or chemical bench contaminants to eyes or mouth
Food is to be eaten in hallways

Familiarize yourself with the location and proper use of the following:
Safety showers
Fire extinguishers
Eye wash stations
Fire alarms
Electrical shutoff (not in all rooms)
Familiarize yourself with the procedure for emergency drill, evacuation and meeting area outside.
Demonstrate or explain proper procedure for use and where each is located

10. WHMIS Hazard Classifications
Class A: Compressed Gas
Class B: Flammable & Combustible
Class C: Oxidizing Material
Class D: Poisonous & Infectious Material
Compressed gas any gas in tanks, oxygen, carbon dioxide
Flammable, alcohol, other solvents
Oxidizing material reactive with other chemicals perchloric acid
Poisonous and infectious materials
Skull and crossbones division 1: materials causing immediate and serious toxic effects (sodium cyanide)
Division 2 (“T”) materials causing other toxic effects These can cause severe immediate reactions or life threatening long term health effects such as immediate eye or skin irritation, allergic sensitization, cancer, reproductive problems (xylene, asbestos)
Division 3 biohazardous infectious materials (bacterial cultures or specimens such as blood that may contain potentially dangerous bacteria or viruses

11. WHMIS Hazard Classifications
Class E: Corrosive Material
Class F: Dangerously Reactive Material
Corrosive example acids
Dangerously reactive sodium
