WHMIS - Workplace Hazardous Materials Information System Rights and Responsibilities Questions and Answers 1 — Questions and Answers
Question 1: Under WHMIS, which of the following is a primary responsibility of the employer?
- Classifying hazardous products and creating initial SDS for suppliers.
- Independently testing all hazardous products before they enter the workplace.
- Ensuring workers are educated and trained on the safe use of hazardous products. (Correct answer)
- Selling personal protective equipment to workers who handle hazardous materials.
Correct answer: Ensuring workers are educated and trained on the safe use of hazardous products.
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?
- Guess the contents based on the container's shape and color.
- Report the damaged label to their supervisor immediately. (Correct answer)
- Continue using the product since they have used it before.
- Create a new label with the information they can remember.
Correct answer: Report the damaged label to their supervisor immediately.
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?
- The right to conduct their own chemical hazard assessments.
- The right to choose which brand of hazardous product to use.
- The right to refuse work they have reasonable grounds to believe is unsafe. (Correct answer)
- The right to modify supplier labels with additional information.
Correct answer: The right to refuse work they have reasonable grounds to believe is unsafe.
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?
- Provide on-site training for every workplace that purchases the product.
- Classify the product's hazards and provide a compliant label and Safety Data Sheet (SDS). (Correct answer)
- Offer a discount on personal protective equipment with every purchase.
- Ensure the product is used correctly by the end-user.
Correct answer: Classify the product's hazards and provide a compliant label and Safety Data Sheet (SDS).
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?
- Ensuring the SDS is readily accessible to all workers who may be exposed to the product.
- Updating the supplier's SDS with workplace-specific information. (Correct answer)
- Training workers on the specific hazards and safe handling procedures for this new product.
- Creating a workplace label if the product is decanted into a different container.
Correct answer: Updating the supplier's SDS with workplace-specific information.
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.
Question 6: The 'Right to Know' is a fundamental worker right within WHMIS. This right is primarily fulfilled through which of the following employer-provided elements?
- Annual performance reviews and safety bonuses.
- Company-wide meetings about production targets.
- Access to the workplace's financial statements.
- Worker education programs, accessible SDSs, and proper labelling. (Correct answer)
Correct answer: Worker education programs, accessible SDSs, and proper labelling.
The worker's 'Right to Know' is fulfilled by ensuring they have access to information about the hazards they may encounter. Employers achieve this through the core components of WHMIS: providing comprehensive worker education and training, ensuring all hazardous products are correctly labelled, and making up-to-date Safety Data Sheets (SDSs) readily available.
