Which of the following can be considered an ignition source at hazmat scenes?

• A. Radios
• B. Water bottle
• C. Safety goggles
• D. Paper clip

Answer: (A)

Ignition sources at hazmat scenes are anything that can provide enough energy to ignite a flammable vapor-air mixture. Radios fit this category because they are electrical devices powered by batteries and circuits, which can produce sparks or electrical arcing, especially if damaged or malfunctioning or when turning the device on or off near vapors. That energy can ignite a nearby flammable cloud.

A water bottle does not generate energy or sparks. Safety goggles are protective equipment, not energy sources. A paper clip is just a metal object and is not a deliberate ignition source in this context; it would only spark under unusual circumstances and is not the typical hazard at hand.
