I'm doing it.

In addition, when looking at the driving characteristics of diesel cars at the fire department, firefighters complain of pain mainly due to the exhaust gas caused by emergency checks (fire fighting vehicles, various communication equipments, etc.) in the morning, and especially, start in the cold state in the morning. In the early stages, white smoke is produced due to the combustion characteristics, and blue smoke is generated after a short time. These smokes are mainly aldehydes, so the eyes are tingling and gastrointestinal, which acts as a danger to the human body. When completely burned, NOx and graphite (Black smoke) are generated. As it turns into a weighting material, it generates fine dust.

As we have seen, the exhaust gas of diesel fire-fighting vehicles contains many harmful factors to the human body, and these residual gases are circulated in the garage, so they are inhaled into the human body through the respirators of firefighters who spend most of their time indoors. This can lead to health hazards.
