Within the field of firefighting, National Fire Protection Association (NFPA) created a standard used at all incidents to which firefighters respond. It is called LIPE: Life Safety, Incident Stabilization, Property Conservation, and Environmental Protection. Whenever responding to some sort of fire, firefighters face smoke, which in turn is a large cause of cancer for this riskful job.
Within firefighting, there have been many improvements made to the safety of firefighters; one place where this is lacking is within the hoods of turnout gear. When firefighters face intense heat, large amounts of pores in their skin open up, letting in carcinogens that are from the smoke and soot left on the hood. Within some departments, hoods are rarely washed; in others, they only give out one hood to each person due to the expensive cost.
