Firefighter cancer-related death statistics continue to rise.
Additionally, statistics show that more than 50 percent of all firefighter line-of-duty deaths (LODDs) in the past decade were caused by cardiac failure following excessive heat stress exposure. The numbers don’t lie, and I’m pretty confident that our jobs are dangerous enough dealing with the life-threatening hazards we respond to. The life-threatening hazards that we as firefighters need rescue from are those that we can’t see, like occupational cancers and heat stress-related cardiac issues. We owe it to ourselves, and especially our loved ones, to become educated and do what we can to minimize our exposure on the fireground (while still committing to aggressively fighting fire).
The science also shows that we are routinely exposed to the carcinogenic toxins of smoke and soot not only through inhalation but also through exposure via bare skin - on the head, face, and neck. Think about it: When we come off of air at a fire, we are typically hot and sweaty from exertion and heat exposure, right? We get clear (best practice), pull our helmet and our hood, and remove our self-contained breathing apparatus (SCBA) mask prior to “opening up” our personal protective equipment (PPE). As you envision this process, where is the least protected part of your body while you fight fire? The only thing that protects our face, ears, and neck is that single-layer hood. Most everything else that we wear has some combination of thermal and moisture/particulate barriers built into it, such as our turnout gear, our helmets, and our SCBA masks.
Since the beginning of (firefighting) time, we used this to our advantage. When we felt our ears starting to roast, it was time to back off or back out. That’s because that thin hood we wear allows us to feel excessive heat on our faces. Unfortunately, those hoods are also permeable enough to allow the aforementioned toxins to permeate the fabric and come in regular contact with the skin on our faces and necks.

Extreme Heat Stress
When tones drop in the firehouse or volunteers’ pagers go off for a response, our heart rates automatically increase. Endorphins are released into our body, and we are off to the races. We then turn out in bunker gear that is designed to protect us from the properties of fire. As soon as we don our gear, our core body temperature rises, even before we begin to physically exert ourselves on scene. From that moment on (provided we are wearing our gear properly), there is very little opportunity for that heat (and increase in core body temperature) to be released or reduced until the call is over or we get a chance to “open up.” But what about those areas of the country where “opening up” doesn’t really help, in part because of the hot and humid weather conditions?
