Which of the following is NOT a WHMIS hazard class?

Skin corrosion/irritation
Carcinogenicity
Acute toxicity
Sharp objects

The correct answer is: Sharp objects

The choice regarding sharp objects is correct because it does not fall under any of the recognized WHMIS (Workplace Hazardous Materials Information System) hazard classes. WHMIS is a comprehensive communication system for hazardous materials used in Canadian workplaces, categorizing substances that pose specific types of risks to health and safety. The other options represent established classes under WHMIS. Skin corrosion/irritation pertains to substances that can cause damage or irritation to skin tissue. Carcinogenicity relates to materials that have the potential to cause cancer in humans upon exposure. Acute toxicity refers to substances that can cause adverse effects following a single exposure, encompassing a range of chemicals. Unlike these defined categories, sharp objects do not represent a hazard class within WHMIS, as they are categorized based on mechanical injury risk rather than chemical hazards.
