Which action is NOT recommended during a pesticide fire?

• A. Use water jets to put out the pesticide fire
• B. Evacuate the area
• C. Use a foam extinguisher
• D. Call emergency services

Answer: (A)

When a pesticide fire happens, safety and avoiding spread of the material are the top priorities. Using water jets is not recommended because many pesticide fires involve flammable liquids; water can spread the pesticide, spread the fire to a larger area, and may not effectively cool or smother the fuel. Water can also cause splashing and vaporization that increases exposure to toxic fumes.

Evacuating the area and calling emergency services are essential steps to protect people and bring trained responders with the right protective gear and equipment. A foam extinguisher is a good choice when appropriate, because foam blankets the fire and creates a barrier between the fuel and air while helping to cool and suppress the fire.
