Separate Chemicals to Prevent Cross Contamination Separate chemicals by class to minimize risk. For example, keep combustibles away from flammables, and prevent cross contamination with seed, fertilizers and other materials such as fuel or oil. If possible, use secondary containers, including concrete curbing, to further prevent cross contamination and minimize environmental contamination in case of spills. Add Ventilation if Necessary Keep hazardous fumes to a minimum by ensuring adequate ventilation of all chemical storage areas. This will minimize the risk of explosion, fire, environmental contamination and human exposure.
Natural ventilation works best when vents are near the floor and ceiling.
Mechanical ventilation, however, offers more control over the air quality and temperature of your storage facility. Protect from Flames and Temperature Extremes Keep crop protection chemicals out of direct sunlight and temperature extremes. This is especially important for liquid formulations. Be sure not to weld or cut with acetylene torches near storage of flammable products or vapors. Aggressively enforce no-smoking rules among employees and visitors whenever entering or working in pesticide storage areas.
