Antonio did NOT read and follow the label directions on the foggers (or bug bombs). According to the instructions, he should have used two foggers instead of nine based on the size of his home (see below for calculations). This increased the amount of flammable vapors in the air (i.e., vapors that burn easily) and increased the risk of an explosion and a fire. Antonio did not turn OFF the pilot light for the water heater in the utility room and the flame ignited the vapors, causing the explosion and fire.

Labels provide important information about the proper use of pesticide products, so please Read The Label Carefully - It's the Law! Do NOT use more foggers than necessary and turn OFF all ignition sources (e.g., pilot lights, open flames, or sparks from electrical appliances that cycle on and off like refrigerators or thermostats). Refer to the label of the fogger for complete instructions. For more information, visit EPA's webpage about "Should I Use a Fogger?"

Look for the graphic symbol for fire on product labels and the hazard warning statements; e.g., "This product contains a highly flammable ingredient. It may cause a fire or an explosion if not used properly."

Remember, using too many foggers may not only increase the risk of an explosion or a fire, but may cause residents to become sick. To learn more about how to reduce your risk of getting sick, refer to NPIC's Common Pesticide Question: One or Three? Too many foggers can hurt me.

Cubic Feet (volume of living area) = Width x Length x Height of each room. Next, add the volumes of all the rooms together. Labels for most foggers state that no more than 1 ounce of product per 1,000 cubic feet should be used. Read the label directions - do not use more foggers than necessary.

Consider contacting the manufacturer of the fogger for detailed information on its use, including how many foggers to use.
