70% to passThe flame screens installed on sewage system tank vents prevent explosions by _______________.
Aallowing the escape of flammable vapors
Bdissipating the heat of a flame
Cabsorbing any flammable vapors in the vicinity
Dpreventing flammable vapors from entering the tank
AI Explanation
The correct answer is B) dissipating the heat of a flame. Flame screens installed on sewage system tank vents are designed to prevent explosions by dissipating the heat of a flame, rather than allowing the escape of flammable vapors, absorbing vapors, or preventing vapors from entering the tank. The flame screen acts as a heat sink, absorbing the energy of a flame and preventing it from reaching the flammable vapors inside the tank. This effectively extinguishes the flame and prevents an explosion from occurring. The other answer choices do not accurately describe the primary function of the flame screen in this application.
