Did you know most fires release dangerous chemicals? Despite advances in technology firefighters are regularly exposed to benzene, formaldehyde, asbestos and other harmful substances. Deadly combinations of gases and particles during and long after a fire is put out can be inhaled, absorbed through the skin, or ingested.
Research shows human beings perform at the optimal when they follow the circadian rhythms - physical, mental, and behavioral changes that follow a 24-hour cycle. Our body's internal clock, also known as the suprachiasmatic nucleus (SCN), regulates these rhythms, responding to light and darkness to synchronize bodily functions with the day-night cycle. Irregular work hours can weaken the immune system and increase cancer risk. Many first responders rotate between working day and nightshifts through their careers which disrupt their sleep patterns, limit exposure to daylight and increase stress.
Fire departments go to great lengths to develop, improve and secure the latest personal protective equipment (PPE). However, this equipment may not fully prevent exposure to carcinogens. Dangerous particles can linger on gear and be absorbed over time.
Carcinogens such as polycyclic aromatic hydrocarbons (PAHs) and other toxic compounds are present in dangerous levels in smoke and soot. Therefore, firefighters are exposed to many health risks including different types of cancers.
