Which of the following strategies can reduce fire hazards in pesticide storage?

Using foam-type fire extinguishers is an effective strategy for reducing fire hazards in pesticide storage because these extinguishers are designed to smother fires, particularly those involving flammable liquids, which can include some pesticide compounds. Foam extinguishers create a blanket over the burning material, cutting off the fire's oxygen supply and cooling the flames. This method is vital in a pesticide storage environment where the risk of combustion exists due to the chemical properties of the pesticides.

In contrast, the other strategies listed do not contribute to fire safety. Keeping pesticides in bright light can increase temperatures and potentially contribute to igniting vapors. Storing pesticides near steam lines can create a risk of overheating and increased pressure within containers, leading to catastrophic failures. Stacking containers in direct sunlight can further elevate temperatures, increasing the chances of chemical reactions or vaporization that could lead to a fire. Therefore, using foam-type fire extinguishers is a proactive measure that addresses fire risks effectively in such settings.
