Poisonous and infectious material

The correct answer is: Poisonous and infectious material

The Workplace Hazardous Materials Information System (WHMIS) is Canada's national hazard communication standard. It is divided into different classes based on the nature of the hazards the materials present. Class D specifically refers to poisonous and infectious material. This means these materials can cause death or permanent damage as a result of single or repeated exposure. This classification includes substances that are biohazards causing diseases, like HIV, as well as toxic substances that could lead to immediate and serious toxic effects or even death. Hence, the correct answer is Poisonous and infectious material.
