What form of exposure is dangerous when handling Class 6 poisons and infectious substances?

When handling Class 6 poisons and infectious substances, it is crucial to recognize that multiple routes of exposure can pose serious dangers. The correct option identifies that inhalation, ingestion, and skin/eye absorption are all significant forms of exposure.

Inhalation is particularly dangerous because it allows toxic substances to enter the respiratory system directly, where they can quickly affect the lungs and even enter the bloodstream. Ingestion poses a risk as well; consuming contaminated materials can lead to internal poisoning or infection. Skin absorption can occur when hazardous substances come into contact with the skin or mucous membranes, which can lead to systemic effects.

Each of these routes offers a pathway for potentially harmful agents to enter the body, emphasizing the need for proper handling and safety protocols when working with Class 6 materials. Understanding these exposure routes helps ensure appropriate protective measures are implemented during the handling and transportation of these dangerous substances.
