The Diagnose Early breath test looks for toxins

You are exposed
to toxins daily

Every fire releases a noxious cloud of toxins. Some you breath in, others are absorbed through your skin.

Get tested regularly for toxins

Regular breath tests help you see what you are being exposed to

toxins exposure timeline

Your body metabolizes some toxins in days but chemicals like PFAS stay in your body forever. In both cases, it can take years before you realize the negative health impacts.

Benzene is a good example: it is metabolized in hours, however, long term exposure leads to aplastic anemia, leukemia, and multiple myeloma.

We recommend tests every 3-4 months to ensure timely detection

SCBA reduces your toxin exposure

Firefighters wearing SCBA

Many toxins are absorbed by breathing them in. But not all of them are visible as smoke. Your SCBA is designed to protect you against these toxins.

  • Mask up before you are exposed to toxic smoke

  • Change hoods before re-entry in the fire scene

  • Decontaminate gear before getting in the truck

  • No gear allowed in the living quarters of the station
