WHMIS - Workplace Hazardous Materials Information System Supplier and Workplace Labels Questions and Answers 1 — Questions and Answers
Question 1: Which of the following elements is required on a WHMIS supplier label but NOT on a workplace label?
- Product identifier
- Safe handling precautions
- Supplier identifier (Correct answer)
- Reference to the Safety Data Sheet (SDS)
Correct answer: Supplier identifier
A WHMIS supplier label must include the name, address, and telephone number of the manufacturer or importer. This information is not a mandatory requirement for a workplace label, which focuses on the product name, safe handling, and a reference to the SDS.
Question 2: An employee decants a hazardous cleaning chemical from a large drum with a supplier label into a smaller spray bottle to use over the next few days. What type of label is required on the spray bottle?
- No label is needed if it's for immediate use.
- A hand-written note with the product name is sufficient.
- A full supplier label must be duplicated.
- A workplace label with key safety information. (Correct answer)
Correct answer: A workplace label with key safety information.
When a hazardous product is transferred to a new container and is not for immediate use by only that person during their shift, a workplace label is required. This label must include the product name, safe handling precautions, and a reference to the SDS.
Question 3: According to WHMIS regulations, what are the three mandatory pieces of information required on a workplace label?
- Product identifier, supplier name, and hazard pictograms.
- Product identifier, safe handling precautions, and a reference to the SDS. (Correct answer)
- Signal word, hazard statements, and precautionary statements.
- Date of decanting, employee's name, and pictograms.
Correct answer: Product identifier, safe handling precautions, and a reference to the SDS.
A WHMIS workplace label must contain three key pieces of information: the product name (identifier) that matches the SDS, information about safe handling (which can include pictograms), and a statement indicating that a Safety Data Sheet is available.
Question 4: A supplier label on a newly received hazardous product has become torn and is now unreadable. What is the employer's responsibility?
- Return the product to the supplier immediately.
- Use the product anyway, as long as the SDS is available.
- Attach a workplace label to the container. (Correct answer)
- Contact the manufacturer to request a new supplier label.
Correct answer: Attach a workplace label to the container.
If a supplier label becomes lost or illegible, the employer is responsible for replacing it with a workplace label to ensure workers have the necessary hazard information.
Question 5: Which statement accurately describes the language requirements for WHMIS supplier labels in Canada?
- They must be in English only.
- They can be in either English or French.
- They must be in the primary language of the workplace.
- They must be in both English and French. (Correct answer)
Correct answer: They must be in both English and French.
WHMIS regulations mandate that supplier labels must be bilingual, providing all required information in both of Canada's official languages, English and French. This can be on a single bilingual label or two separate labels.
Question 6: A workplace label is NOT required when an employee transfers a hazardous product into a portable container if...
- the container is smaller than 100 mL.
- the product is only moderately hazardous.
- the employee who filled it will use it all during that same shift. (Correct answer)
- the product is transferred in a well-ventilated area.
Correct answer: the employee who filled it will use it all during that same shift.
An exception to requiring a full workplace label exists for decanted products if the person who poured it will be the only one using it, and it will be used completely during their current work shift. The container must still be identified with the product name.
