Question 96Safety & Environmental - QMED

The correct answer is D) All of the above. The explanation is as follows: 1) The fire produces smoke, which contains toxic gases that cause breathing difficulties and irritation of the respiratory tract. 2) The fire consumes oxygen, which may lead to asphyxiation. 3) The fire produces carbon monoxide, which causes an oxygen deficiency in the brain and body, leading quickly to death. All of these factors make it essential to wear a self-contained breathing apparatus (SCBA) before entering a closed compartment to fight a fire. The SCBA provides a reliable supply of clean, breathable air, protecting the firefighter from the hazardous conditions created by the fire.
