True or False: After a spill is contained, securing the area from bystanders is necessary.

Securing the area from bystanders after a spill is contained is imperative for safety. This is because even after containment, the spilled material can still pose hazards, either from toxicity or the potential for re-exposure. By ensuring that the area is secured, you prevent accidental contact with individuals who may not be aware of the dangers that remain. This is especially critical in pest control, where many substances can be harmful if inhaled or absorbed through the skin.

In addition, securing the area allows for proper cleanup procedures to be conducted without hindrance and ensures that only trained personnel are handling the situation. It also provides an opportunity to assess the spill thoroughly and evaluate any potential risks associated with cleanup.
