Learn why cigarettes won't burn in submarines due to low oxygen levels designed to prevent fire hazards in confined spaces.

423 views

Cigarettes won't burn in submarines primarily due to the controlled atmosphere that's maintained to ensure the health and safety of the crew. In a submarine, the oxygen levels are kept lower than at the surface to reduce the risk of fires. Since fire needs oxygen to burn, the reduced oxygen levels mean that cigarettes simply cannot sustain combustion in this environment. This control is vital in the confined spaces of a submarine, where a fire could be disastrous.

FAQs & Answers

  1. Why is oxygen level lowered inside submarines? Oxygen levels are kept lower inside submarines to reduce the risk of fires, ensuring the confined environment remains safe for the crew.
  2. Can any types of fires occur inside submarines despite precautions? While precautions minimize risk, fires can still occur, which is why strict protocols and controlled atmospheres are maintained onboard.
  3. How does reduced oxygen affect human health on a submarine? Oxygen levels are carefully regulated to balance fire safety and crew health, maintaining levels sufficient to support normal breathing.
