What are some common routes of exposure to hazardous materials?

The correct choice highlights the primary routes through which individuals can be exposed to hazardous materials. Inhalation is a significant route because many hazardous substances can be absorbed directly into the bloodstream or tissues through the respiratory system when they are airborne. This exposure can occur in various environments, including occupational settings and areas near hazardous waste sites.

Ingestion occurs when hazardous materials enter the body through the mouth. This can happen if contaminated hands, food, or water are consumed. It poses significant risks since ingested toxins can affect various bodily systems, potentially leading to severe health consequences.

Skin contact is another important route of exposure, particularly in cases where hazardous substances can penetrate the skin barrier. Many chemicals can cause dermal absorption, resulting in systemic toxicity or localized effects, such as burns or rashes.

Recognizing these routes emphasizes the need for proper safety protocols and personal protective equipment to minimize exposure risks in environments where hazardous materials are handled or stored.
