This is the WHMIS hazard symbol for what material?

• A. Class A. Compressed Gas
• B. Class B. Flammable and Combustible Materials
• C. Class C. Oxidizing Materials
• D. Class D. Poisonous and Infectious Materials

Answer: (C)

The WHMIS hazard symbol representing Class C materials pertains to oxidizing substances. Oxidizing materials are those that can enhance the combustion of other materials, meaning they can cause or increase the intensity of a fire. These substances can release oxygen or other oxidizing gases when they decompose, leading to dangerous fire conditions when in contact with combustible materials.

Identifying oxidizers is crucial for safe handling and storage, as they can pose significant risks in various industrial settings. In terms of WHMIS training, this classification emphasizes the need for proper labeling, safety data sheets, and appropriate protective measures when working with these materials.

Conversely, the other classes—compressed gases, flammable and combustible materials, and poisonous and infectious materials—target different hazards, such as pressure risks or toxicity. Understanding oxidizers as a distinct category helps workers recognize specific safety precautions necessary when managing these chemicals.
