WHMIS - Question and answers- is a national hazard wide communication system
- Created to inform workers of the hazardous materials they work with
Why was WHMIS created? - Question and answers- inform about the safety and health
hazards associated with the hazardous materials they might use at work
- Reduce injuries and illnesses associated with handling hazardous materials in the
workplace
GHS - Question and answers- Global Harmonized System
-Move to standardize communication about hazardous products internationally
GHS consists of... - Question and answers- Health hazards
- Physical hazards
- Environmental hazards (NOT ADOPTED BY CANADA)
WHMIS 2015 - Question and answers- Canada's response to Globally Harmonized
System (GHS)
Consists of
- Labels (provides info about product and hazards)
- SDS (detailed info about hazards)
- Education (Training on how to safely handle hazardous products)
Suppliers - Question and answersClassifying products
Establishing health and safety information
Labelling products
Preparing and providing SDS's
Employer - Question and answersEnsure proper labels
Provide access to SDS's and update
Educate workers, and evaluate competency
Train workers on how to handle, use, store, wear PPE for hazardous products, assess
competency
,Provide control measures, adhere to Routine practices
Employees - Question and answersParticipating in education and training
Following prescribed safe work procedure
Identifying and controlling hazards
Hazardous Product - Question and answers- Hazardous products are materials,
products, or substances that meet any of the criteria for one or more of the 32 GHS
Hazard Classes as defined in the Federal Hazardous Products Regulation
- Grouped into physical and health hazards
- WHMIS does not provide a comprehensive list of hazardous products, only a list of
hazard criteria.
Exclusions from WHMIS - Question and answers- WHMIS may not apply if another act
or regulation is in place
- The following are exempt from the supplier responsibilities of WHMIS (no label or SDS
required):
•Consumer restricted products: products sold in stores that already have labels in
accordance with the Canada Consumer Product Safety Act
•Explosives: covered by the Explosives Act
•Cosmetics, drug, food, or devices: covered by the Food and Drugs Act
•Pesticides, herbicides, and insecticides: covered by the Pest Control Products Act
- Employer still responsible for for training employees on the safe use, handling, and
storage of these materials
more exceptions - Question and answersRadioactive materials: covered by the Nuclear
Safety and Control Act
Wood and wood products•Manufactured articles that will not release chemicals
•Tobacco or tobacco products•In-house generated hazardous waste
•Hazardous materials transported under the Transportation of Dangerous Goods act
(TDG)
,Radioactive Materials - Question and answersGHS labels and SDS's are still required
when there are mixtures of radioactive nuclide(s) and non-radioactive carrier material
whereby:
The carrier material is greater than 1 mL / 1 g
•The carrier material poses a carcinogenic, toxic, or infectious hazard
Health Hazard Class - Question and answersbased on a products ability to result in a
health related issue
Acute toxicity - Question and answersProducts that are fatal, toxic, or harmful if they
come in contact with the skin, are inhaled, or swallowed
Skin corrosion/irritation - Question and answersProducts that can cause severe skin
burns or irritations
- Both physical and health hazard
Respiratory or skin sensitization - Question and answersProduct that may cause
asthma or allergy like symptoms or difficulty breathing
Germ cell mutagenicity - Question and answersProducts that may cause or are
suspected to cause genetic defects
Carcinogenicity - Question and answersProducts that may cause or are suspected to
cause cancer
Reproductive toxicity - Question and answersProducts that may cause damage or are
suspected to damage ones fertility or an unborn baby
Specific target organ toxicity - single exposure - Question and answersproducts that can
cause damage to organs following a single exposure
Specific target organ toxicity - repeated exposure - Question and answersProducts that
can cause damage to organs following prolonged or repeated exposures
Health hazards not otherwise classified - Question and answersProducts that may
cause health hazards following single or repeated exposures, including risk of injury or
death
Physical Hazards Group: - Question and answersbased on physical and chemical
properties of a given product
Flammable gases - Question and answersProducts can readily ignite, creating hazard
for fire or explosion
, Oxidizing gases - Question and answersOxidizers that can cause a fire or explosion or
intensify a fire
Gases under pressure - Question and answersGases under high pressure in a cylinder
or container that have potential to explode and cryogenics that can cause severe burns
Self-reactive substances and mixtures - Question and answersProducts which may
react to create a fire or explosion, or upon heating cause a fire or explosion
Pyrophoric liquids - Question and answersProducts that ignite spontaneously in the
presence of air
Self-heating substances and mixtures - Question and answersProducts that can ignite
in the presence of air after a duration of time
ORGANIC PEROXIDES - Question and answersUpon heating, products that can cause
a fire or explosion
Combustible dust - Question and answersFinely divided particles that, if in air, can catch
fire or explode upon ignition
Simple asphyxiants - Question and answersGases that displace air, causing suffocation
Environmental Hazards Group: - Question and answersbased on a products ability to be
harmful to the environment
- Question and answersGroup and classes NOT adopted in the Hazardous Products
Regulations
Classifying Hazards - Question and answersBoth Physical & Health Hazards are
subdivided into:
Categories are assigned a number (e.g. 1, 2, 3)
Subcategories (e.g. 1A, 1B, 1C)
Categories can also be referred to as types (e.g. A, B, C)
The lower the category number, the higher the hazard
- Question and answersHazzard group: Health or Physical
Hazzard class: Skin corosion
Hazard category: 2
