And so can you talk about that and how firefighters can also mitigate their exposure?

Yeah.

So PAHS, PHAs are combustion byproducts.

So basically it's the soot, um, and the smoke that firefighters encounter typically during structural fires.

Crews oftentimes are trai- ... and we're trained to actually use SCBAs, which are basically gas masks, for lack of better terms.

However, they're, they are made to minimize exposure, but despite the, the mask, oftentimes men and women are exposed to the smoke and the soot regardless, whether it's directly through the mask and or after exposure after the mask is removed.

A lot of times the men and women in the fire service, you know, they, they are doing things in a quick manner, oftentimes even afterwards, after the fire's put out, and they expose themselves to a lot of these things as a result of not following protocol per se.

How do you identify these invisible exposures, and how do they affect the firefighter's career?
