What does the term "exposure" refer to in the context of Hazard Communication?

The term "exposure" in the context of Hazard Communication specifically refers to the contact that an individual has with a hazardous substance, which can occur through various routes such as inhalation (breathing in), dermal absorption (contact with skin), or ingestion (swallowing). Understanding exposure is crucial in assessing health risks related to hazardous materials, as it enables workers and employers to implement appropriate safety measures and protective equipment to minimize the risk of harm.

Recognition of these pathways of exposure informs the development of safety protocols and helps in the preparation of Safety Data Sheets (SDS), which provide essential information regarding the hazards associated with chemicals, safe handling practices, and necessary precautions. By accurately identifying and controlling exposure, the health and safety of individuals in a work environment can be significantly improved.
