When a chemical spill occurs, time is of the essence because of the harmful effects on human health and the environment. First, you should evacuate the area to minimize the risk of personnel exposure. Chemical spills can cause fires, explosions, leakages, and the release of toxic or hazardous materials that can cause illness, injury, disability, or even death. You will need someone knowledgeable about the chemical and its specific properties to take charge of the situation and keep your personnel safe from danger. Anyone not involved in the chemical spill cleanup should stay uphill or upwind of the area.
