WHMIS - Workplace Hazardous Materials Information System Rights and Responsibilities Questions and Answers

Question 1

Under WHMIS, which of the following is a primary responsibility of the employer?

Accepted Answer

Ensuring workers are educated and trained on the safe use of hazardous products.

Answer

Employers have a crucial responsibility under WHMIS to provide workers with the necessary education and training to understand the hazards of the materials they work with and how to handle them safely. This includes understanding labels, SDSs, and safe work procedures.

Question 2

A worker discovers a container with a torn and illegible supplier label. According to their WHMIS responsibilities, what is the most appropriate first step for the worker to take?

Accepted Answer

Report the damaged label to their supervisor immediately.

Answer

A worker's responsibility includes participating in identifying and controlling hazards. When a label is illegible, the product's hazards are unknown, creating a risk. The worker must report this to their supervisor so that the product can be properly identified and a workplace label can be created before it is used.

Question 3

Which of the following best describes a key right granted to workers under WHMIS legislation?

Accepted Answer

The right to refuse work they have reasonable grounds to believe is unsafe.

Answer

WHMIS is part of the broader Occupational Health and Safety legislation, which grants workers three fundamental rights: the right to know about workplace hazards, the right to participate in health and safety activities, and the right to refuse unsafe work without fear of reprisal.

Question 4

A chemical manufacturing company creates a new cleaning solvent that will be sold to various industrial workplaces. What is this company's primary responsibility as a WHMIS supplier?

Accepted Answer

Classify the product's hazards and provide a compliant label and Safety Data Sheet (SDS).

Answer

The primary duties of a WHMIS supplier are to classify hazardous products according to specific criteria, and then to communicate those hazards to their customers by providing compliant supplier labels and Safety Data Sheets (SDSs) at the time of sale.

Question 5

An employer has just received a new hazardous product with a WHMIS 2015 supplier label and SDS. Which of the following is NOT a direct responsibility of the employer in this situation?

Accepted Answer

Updating the supplier's SDS with workplace-specific information.

Answer

While employers must provide workplace-specific training and create workplace labels when needed, they are not responsible for altering the original SDS provided by the supplier. The supplier is responsible for the accuracy of the SDS they provide. Employers must ensure the supplier SDS is accessible, not modify it.
