What are the routes of exposure to toxic substances?
Workers can be exposed to toxic substances through inhalation, skin contact, ingestion, and injection. Inhalation is a common route of exposure in environments where toxic substances are airborne, such as in spray painting or welding. Skin contact can occur when handling chemicals without proper protective gear. Ingestion is less common but can happen if food or drink is contaminated. Injection is rare and typically occurs in specific scenarios such as needlestick injuries in healthcare settings.
