If you are not sure what to use to put out hazardous materials fires, you should:

• A. Wait on qualified firefighters
• B. Use water immediately
• C. Use a standard fire extinguisher
• D. Try to fight it yourself

Answer: (A)

Hazardous materials fires require trained responders with the right protective gear and knowledge of the specific material involved. If you’re unsure what to use, you should not try to fight the fire yourself. Different chemicals react differently with water or with common extinguishing agents, and using the wrong method can make the fire worse, release toxic fumes, or endanger you and others. Qualified firefighters will identify the substance, assess the risks, and choose the appropriate suppression technique and agent, plus take steps to contain the spread and protect people and the environment. In the meantime, evacuate if you can do so safely, stay upwind, and call emergency services so trained personnel can handle the situation. Waiting for those professionals is the safest course of action.
