What does WHMIS stand for?
Explanation:
WHMIS stands for Workplace Hazardous Materials Information System. This system is designed to provide information about hazardous materials in the workplace, including their potential health effects, safe handling procedures, and necessary precautions. It is important for employees to be aware of and understand WHMIS in order to work safely with hazardous materials and protect their health.
What is the purpose of WHMIS?
Explanation:
The purpose of WHMIS (Workplace Hazardous Materials Information System) is comprehensive and includes all of the listed options. It is designed to identify hazardous materials within the workplace and ensure they are handled safely, reduce accidents and health hazards, and increase safety for everyone in the workplace. WHMIS achieves these goals through proper labeling, the provision of safety data sheets, and effective worker training. This system helps to create a safer work environment by informing workers about the risks associated with materials they may encounter and how to properly manage those risks.
What are the routes of entry for a chemical?
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.

Which WHMIS class includes flammable materials?
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.
What does the following WHMIS symbol warn you about?

What type of information does the WHMIS pictogram with a flame over a circle represent?
Explanation:
The WHMIS pictogram with a flame over a circle warns of oxidizing hazards. Oxidizers can dramatically increase the rate of 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.
