Q

What is the procedure for a work refusal?

A

First stage
Worker:
-considers work unsafe.
-reports refusal to his/her supervisor or employer.
-may also advise the worker safety representative and/or management representative.
-stay in safe place.
Employer or supervisor investigates in the presence of the worker and the worker safety representative.
Either:
Issue resolved. Worker goes back to work.
Issue not resolved. Proceed to the second stage

Second stage
With reasonable grounds to believe work is still unsafe, worker continues to refuse and remains in safe place. Worker or employer or someone representing worker or employer calls MOL.
MOL Inspector investigates in company of worker, safety representative and supervisor or management representative. Pending MOL investigation:
Inspector gives decision to worker, management representative/supervisor and safety representative in writing.
Changes are made if required or ordered. Worker returns to work.

The refusing worker may be offered other work if it doesn’t conflict with a collective agreement

Refused work may be offered to another worker, but management must inform the new worker that the offered work is the subject of work refusal. This must be done in the presence of:
a JHSC member; or
a health and safety representative, or
a worker who because of his or her knowledge, experience and training is selected by the trade union that represents the worker or, if there is not trade union, by the workers to represent them.

Q

What happens when a worker refuses unsafe work? (first stage of work refusal procedure)

Worker must immediately tell the supervisor that the work is being refused and explain the circumstances for the refusal.

Supervisor must investigate the situation immediately, in the presence of the worker and JHSC member, certified member if possible

The refusing worker must remain in a safe place near workstation, and remain available for the purposes of the investigation, until completed. If the situation is resolved at this point, the worker will return to work.

Q

Why do we need WHMIS?

A

Prevents injuries from chemicals

Need to know about the chemicals you work with

3x more deaths every year from exposure to chemicals than from traumatic injuries

Many people cannot work (or play) due to work related diseases e.g. asthma, dermatitis

Q

What are the 4 key elements of WHMIS?

A
Classification
Hazardous products divided into 2 major groups
Physical Hazards (e.g. combustible, flammable)
Health Hazards (skin irritation, acute toxicity)
Groups then split into classes, depicted by pictograms

WHMIS labels
Identifies products, their hazards, precautions to be taken
Must display some elements in a certain order
Hazard statements and precautionary statements have been standardized

SDS
Detailed hazard and precautionary information
16 section format, information in each section has been standardized

WHMIS education and training programs
Workers need to know:
How WHMIS works
Hazards of products in the workplace
Safe work procedures that must be followed

A

Class A
Wood, paper, cloth, trash, plastics
Solid combustible materials that are not metals

Class B
Flammable liquids
Gasoline, oil, grease, acetone
Flammable gases

Metals

25
Q

How can you prevent fires for each class?

A

Class A:
keep storage and working areas free of trash
Place oil rags in covered containers

Class B:
Don’t refuel gas-powered equipment while its hot or in a confined space
Keep flammable liquids stored in tightly closed, self-closing or spill proof containers

Class C
Look for old wiring, worn insulation and broken electrical fittings
Prevent motors from overheating - keep clean and in good working condition
Don’t misuse fuses
Utility lights must have a wire guard
Don’t overload wall outlets

26
Q

What are the 3 types of fire extinguishers?

A

Air-Pressurized Water extinguishers (APWs) - Silver
For Class A fires only
large (2’), silver, approx. 25 lbs when full
Filled 2/3 water, 1/3 pressurized air
Essentially a giant squirt gun

Dry Chemical extinguishers - Red
DC = dry chemical
ABC = for Class A, B and C class fires
BC = for Class B and C
Important to identify which types are in your area
Coat fuel with thin layer of dust
 = separates fuel from air/O2

Carbon Dioxide extinguishers - Green
Non-flammable CO2 under extreme pressure
Identified by hard horn and lack of pressure gauge
Displaces O2
Very cold as it comes out = cools the fuel
May be ineffective for Class A

27
Q

What would you keep in mind before considering fighting a fire

A

You don’t know what is burning

If spreading quickly, best to:

  • Evacuate building
  • Close doors and windows behind you as you leave
