Every fire is different. Each structural or vehicle fire involves different hazards and exposures. These exposures depend on:
- building material
- materials stored within
- fire conditions, such as temperature and oxygen availability
The phase of a fire can influence exposure level. Knockdown typically has higher exposure to heated gas, vapors, and particulate matter compared to overhaul. Respiratory protection is more likely to be worn during knockdown. Though exposures may still exist at lower levels during overhaul, respiratory protection is less often used.
