Firefighting is the act of extinguishing fires. A firefighter suppresses and extinguishes fires to protect lives and prevent the destruction of property and the environment. Firefighters may provide many other valuable services to their communities including emergency medical services. Firefighting requires professionals with a high technical skill who spend years training in both general firefighting techniques and specialized areas of expertise.
One of the major hazards associated with firefighting operations is the toxic environment created by combustion materials. The four major hazards associated with these situations are smoke, the oxygen deficient atmosphere, elevated temperatures, and toxic atmospheres. Additional risks of fire include falls and structural collapse. To combat some of these risks, firefighters carryself-contained breathing apparatuses.
