Safety

Before You Begin...• Learn to recognize the safety symbols and the

warning symbols for hazardous materials • These include the:• 1) WHMIS symbols

(Workplace Hazardous Materials Information System)

2) HHPS(____________________________________)

What is WHMIS?• Provide information on the

safe use of hazardous materials in Canadian workplaces.

• It has been in effect since October 31, 1988.

Why was WHMIS created? • WHMIS was created to

help stop:-injuries,-illnesses,-deaths-medical costs, and fires

caused by hazardous materials in the workplace.

Classification• WHMIS covers six classes of controlled products,

that are lettered A through F. • Eight hazard symbols are used for these different

classes.• Some products can fall under more than one class

WHMIS labels• The purpose of labels is to:

- alert workers to the main hazards of material- provide instructions for safe handling-to direct workers to the Material Safety Data

Sheet(MSDS) for morenformation.

• The two types of WHMIS labels are:-the supplier label -the workplace label.

WHMIS Symbols: have circle with a drawing in the center

COMPRESSED GAS

FLAMMABLE & COMBUSTIBLE MATERIAL

OXIDIZING MATERIAL

POISONOUS AND INFECTIOUS MATERIAL CAUSING IMMEDIATE AND SERIOUS TOXIC EFFECTS

POISONOUS AND INFECTIOUS MATERIAL CAUSING OTHER TOXIC EFFECTS

BIOHAZARDOUS INFECTIONS MATERIAL

CORROZIVE MATERIAL

DANGEROUSLY REACTIVE MATERIAL

All supplier labels have a broken lined border

What does HHPS stand for?

• H = Hazardous• H = Household • P = Product• S = Symbols

What is the use of the HHPS?

These symbols were created to indicate exactly why and to what degree a household product (e.g. bleach) is dangerous.

Frames indicate the level of danger

Icons display the specific type of hazard

Note: WHMIS symbols have a

circle around the drawing. HHPS do

not

Flammable Hazard• The product could ignite (catch on fire) if exposed to

flames, sparks, friction, or heat.

Poison• The product is very poisonous and could have

immediate and serious effects, including death, if eaten or drunk. Smelling or tasting some products can also cause serious harm.

Explosive Hazard• The container can explode if it is heated or

punctured.

Corrosive Hazard• The product will corrode clothing, skin, or other

materials and will burn eyes on contact.

Laboratory Safety Rules

NO HORSEPLAY IN THE LAB:

PLAYING AROUND IN THE LAB WILL RESULT

IN BEING BANNED FROM LAB ACTIVITIES.

What to wear

• Closed toe shoes.• Pants (no shorts)• Eye protection,

gloves, and apron where indicated.

• Long hair tied back.

Fire Blanket: Use to extinguish small starting

fires.

Fire extinguisher: Can be useful on a person but this

should be avoided as it can cause frostbite and

suffocate.

Eyewash station: Used

to flush eyes if chemical/toxin is splashed into

them.

Broken Glass Bin: Sweep up broken glass (never pick it up with hands) and put it in

broken glass bin, not the regular garbage!
