Chemical Hazards
Chemicals are found in many products used at construction sites. Workers may be exposed to dangerous chemicals during construction activities. These include asbestos, lead, silica, carbon monoxide, and spray paints. The chemicals can exist in several forms, including:
- dusts, fumes, and fibers (solids);
- liquids and mists; and
- gases and vapors.
These chemicals can enter the body in several ways. Let's take a closer look.
Inhalation (breathed in): Inhalation is generally the most common way chemicals can enter the body in a work situation.
Ingestion: Accidental swallowing through eating, drinking, or smoking.
Absorption: A chemical is absorbed through contact with the skin or eyes.
Injection: A chemical enters the body when the skin is punctured.
