What is a basic method to reduce inhalation of toxic gases?

• A. Breathing through wet towels
• B. Running through a contaminated area
• C. Wearing a scarf over the mouth and nose
• D. Holding your breath until the danger passes

Answer: (A)

When toxic gases are present, the goal is to reduce how much of the polluted air reaches your lungs. A damp towel over the mouth and nose creates a simple barrier that can trap some of the gas particles and slow the flow of air into your lungs, lowering your exposure long enough to get to fresh air. Running through the contaminated area would push you deeper into the gas and increase exposure. Holding your breath isn’t reliable and can lead to dizziness or loss of consciousness before you can escape. A scarf might help slightly, but without moisture it’s less effective at filtering and can have gaps that let gas through. The damp towel is the quickest, most practical way to reduce inhalation among these options.
