“Physical activities of fire suppression, rescue or both that are beyond the incipient stage. This includes firefighting to control or extinguish a fire in an advanced stage of burning that is producing large amounts of smoke, heat, and toxic products of combustion.
Firefighting is a complex activity requiring clear definition of roles and responsibilities on the incident ground and is normally undertaken by teams of firefighters. It is important that command and control discipline is maintained to ensure the safety of firefighters and others.
Firefighter training standards are set by the Occupational Safety & Health Agency, which is part of the U.S. Department of Labor. OSHA standards apply to all private employers who establish fire brigades, such as oil companies operating refineries. The standards may also apply to municipal or volunteer fire departments, depending on the state law where the department is located.”
