What does the term 'exposure' refer to in the context of hazardous materials?

In the context of hazardous materials, the term 'exposure' specifically refers to the process of contact with hazardous materials. This involves coming into physical interaction with dangerous substances, which can occur through various routes such as inhalation, ingestion, skin absorption, or eye contact. Understanding exposure is critical, as it can lead to harmful effects on health, depending on the nature of the material and the duration and amount of contact.

This understanding is fundamental for personnel dealing with HAZMAT situations, as it informs how to identify risks, implement safety measures, and respond appropriately during incidents. For example, recognizing how individuals could be exposed allows responders to prioritize protective measures and ensure the health and safety of everyone involved.
