1.

What does WHMIS stand for?

Answer: Workplace Hazardous Materials Information System
Explanation:
WHMIS stands for Workplace Hazardous Materials Information System. It is a Canadian system designed to give employers and workers information about the hazardous materials they may be exposed to at work. WHMIS helps ensure safety by providing details on the use, storage, handling, and emergency procedures related to hazardous materials. The system includes labels on containers, safety data sheets, and worker education programs.
2.

What are the 3 components of WHMIS?

Answer: Labels, MSDS, Worker Training & Education
Explanation:
The three core components of WHMIS are labels, Material Safety Data Sheets (MSDS), and worker training and education. Labels on hazardous products provide immediate information about the dangers and necessary precautions. MSDS offer detailed information on each chemical, including its hazards and how to handle it safely. Worker training and education ensure that employees understand the information on the labels and MSDS and know how to work safely with hazardous materials. This comprehensive approach helps protect workers' health and safety in the workplace.
3.

What are the routes of entry for a chemical?

Answer: Inhalation, absorption, ingestion, injection
Explanation:
The routes of entry for a chemical into the body are inhalation, absorption, ingestion, and injection. Inhalation occurs when chemicals are breathed in through the nose or mouth. Absorption happens when chemicals penetrate through the skin or eyes. Ingestion is when chemicals are swallowed. Injection refers to chemicals entering directly into the bloodstream through a puncture in the skin. Understanding these routes helps in managing and preventing exposure to harmful chemicals.
4.

What three items should be included on a workplace label?

Answer: Product identifier, precautionary measures, MSDS reference
Explanation:
 A workplace label should include a product identifier, which clearly names the chemical or product; precautionary measures, which detail the safety precautions and procedures for handling, storage, and disposal of the product; and a reference to the Material Safety Data Sheet (MSDS), which provides comprehensive information about the chemical. These components ensure that workers have immediate and clear information necessary to safely manage and work with hazardous materials.
5.

A worker has been told to clean the floor with liquid from a drum. The supplier label has been torn off. What should he do?  

Answer: Not work with the liquid; tell his supervisor immediately about the missing label.
Explanation:
 If the supplier label on a drum containing a liquid has been torn off, it's crucial for the worker to not proceed with using the liquid, as the label contains important safety information including the product identity and hazard warnings. The correct course of action is for the worker to stop and report the missing label to his supervisor immediately. This ensures that all necessary precautions are taken and that the substance is correctly identified before any use, preventing potential accidents or exposure to harmful chemicals.
6.

A Material Safety Data Sheet expires after how many years?

Answer: 3 years
Explanation:
A Material Safety Data Sheet (MSDS), now more commonly known as a Safety Data Sheet (SDS) under the globally harmonized system, does not have an expiration date. However, it is important for employers to ensure that the SDS is kept up to date. Manufacturers or suppliers should update the SDS whenever new information becomes available about the chemical's hazards or safety information changes. Employers should check regularly for updates to ensure that the most current information is available in the workplace for the safety of all employees.
7.

How would you recognize a supplier label?

Answer: Hatched border
Explanation:
A supplier label can be recognized by its hatched border. This means that the label will have a border that is made up of small, diagonal lines. This feature helps to distinguish supplier labels from other types of labels. The other options mentioned in the question, such as being written only in one language, red in color with black writing, and rectangular in shape, may or may not be true for a supplier label, as these characteristics can vary. However, the hatched border is a consistent feature that can be used to identify a supplier label.
8.

What does MSDS stand for?

Answer: Material Safety Data Sheet
Explanation:
MSDS stands for Material Safety Data Sheet. This document provides detailed information about the potential hazards and safety precautions for a specific chemical or product. It includes information on the composition, physical and chemical properties, handling and storage guidelines, emergency procedures, and disposal methods. MSDS is commonly used in workplaces to ensure the safe handling and use of hazardous substances.
9.

What type of information does the WHMIS pictogram with a flame over a circle represent?

Answer: Oxidizing hazards that may cause or intensify a fire.
Explanation:
The WHMIS pictogram with a flame over a circle warns of oxidizing hazards. Oxidizers can dramatically increase the rate of a fire by supplying oxygen, making them extremely dangerous in combustible environments. Recognizing this symbol helps prevent potential disasters by enforcing strict storage and handling guidelines that keep oxidizers away from flammable materials. This ensures a safer working environment, reducing the risk of fire outbreaks and promoting safe practices around substances that could otherwise exacerbate fire conditions.
10.

In WHMIS, what is the primary purpose of a safety data sheet (SDS)?

Answer: To provide information on the hazards, handling, storage, and emergency measures of chemicals.
Explanation:
The primary purpose of a Safety Data Sheet (SDS) in WHMIS is to inform users about the hazards associated with a chemical, along with detailed information on how to handle, store, and react in emergency situations involving the chemical. SDSs are critical for maintaining safety in environments where chemicals are used, ensuring all personnel are well informed about the substances they might encounter. This information helps prevent accidents and injuries, making it an indispensable safety tool in any workplace that handles hazardous materials.
11.

Which WHMIS class includes flammable materials?

Answer: Class B
Explanation:
WHMIS Class B is designated for flammable materials, which include any substance that can ignite easily under normal conditions. This class is vital for workers to recognize as it encompasses flammable gases, liquids, and solids. Proper identification, handling, and storage of Class B substances are crucial in preventing fires and ensuring workplace safety. Workers trained to recognize and respect the properties of flammable materials contribute to a safer working environment, reducing the likelihood of fire-related incidents.
12.

What should be done if a WHMIS label becomes illegible?

Answer: Replace the label with a new one that is readable.
Explanation:
When a WHMIS label becomes illegible, it is essential to replace it immediately with a new, clear label. Proper labeling is a cornerstone of WHMIS regulations, providing crucial information on the handling and hazards of chemical substances. An unreadable label can lead to misuse or mishandling, posing significant risks to health and safety. Replacing the label ensures continuity of information and maintains safety standards, helping to prevent accidents and ensuring that all personnel are aware of the necessary precautions when dealing with hazardous materials.
