What should be done immediately after pesticide application to ensure safety?

Securing the area immediately after pesticide application is crucial for safety to prevent exposure to humans, pets, and wildlife. This involves restricting access to the treated site until it is safe to enter. Properly cordoning off the area helps to ensure that individuals who are not involved in the application process are kept away from potentially harmful substances that could pose health risks if inhaled, ingested, or come into contact with the skin.

Securing the area can involve placing barriers, signs, or using other forms of communication to inform people that pesticide application has occurred. This action is in line with safety protocols designed to minimize risk and promote the safe use of chemical products. Implementing this step also aligns with environmental protection measures to prevent unintended ecological consequences in nearby areas.

Other options do not prioritize the safety of individuals nearby. Leaving the area unmanned does not actively protect the site, inviting others to observe could expose them to pesticides, and opening all windows may not be advisable if it increases the risk of drift or contamination.
