When is it necessary to perform tasks over a spill containment surface?

The necessity to perform tasks over a spill containment surface primarily relates to the potential environmental impact and safety concerns involved in handling large quantities of active ingredients. When mixing and loading more than 1,500 pounds of active ingredient, the risk of a significant spill dramatically increases, necessitating stringent containment measures to prevent contamination of soil and water resources.

Additionally, the regulation to use spill containment surfaces becomes even more critical if these activities occur within 100 feet of a water source, as runoff or accidental spills in this zone could have immediate and lasting effects on aquatic ecosystems. Hence, employing a spill containment surface in these situations is an essential practice to mitigate potential environmental hazards, ensuring compliance with safety standards designed to protect both public health and the environment.
