What items would be considered potential ignition sources at hazardous materials incidents?

The correct choice focuses on potential ignition sources that can contribute to the escalation of a hazardous materials incident. Radios and flashlights are common items that, if not specifically designed for hazardous environments, may produce sparks or generate heat that could ignite flammable vapors or gases present at the scene.

In hazardous materials contexts, it’s essential to consider the specific environments in which these items may be used. For example, a standard flashlight may not be safe to use in a flammable atmosphere, while specialized equipment designed for such conditions is needed.

Other choices listed, such as respirators, gloves, fire extinguishers, hoses, safety cones, and barriers, do not present ignition risks. Instead, they serve protective, containment, or signaling functions during a hazardous materials incident. Recognizing potential ignition sources is vital for maintaining safety and preventing ignition of flammable materials in emergency response situations.
