What hazard can occur to a firefighter standing in a pool of flammable liquid or contaminated runoff?

• A. Personal protective equipment can absorb the product and endanger the firefighter.
• B. Product can break down the rubber in the firefighter's boots.
• C. Runoff is pressure sensitive and can ignite.
• D. Toxicity of foam.

Answer: (A)

When a firefighter stands in a pool of flammable liquid or contaminated runoff, the liquid can saturate and be absorbed by turnout gear and other protective clothing. Gear isn’t completely impermeable—many liquids can permeate the fabric or cling to the moisture barrier—so the product can be carried against the skin. This keeps the chemical in contact with the body longer, increasing the risk of skin burns, chemical exposure, or toxicity. If the liquid remains absorbed, it can also vaporize near the body and create a higher ignition or inhalation risk when heat or an ignition source is present. So, the main danger is the product being absorbed into and carried by the firefighter’s protective equipment, rather than simply acting on the outside or degrading components of gear.
