What is the purpose of setting boundaries during a toxic gas incident?

The purpose of setting boundaries during a toxic gas incident is primarily to protect personnel from possible exposure. Establishing these boundaries helps to create a safety zone that minimizes the risk of individuals coming into contact with harmful substances. By clearly defining a perimeter, authorities can effectively limit access to hazardous areas and reduce the likelihood of accidental exposure or injury to both responders and the public.

In this context, while other factors such as confining the area, providing access for emergency responders, and ensuring proper evacuation are relevant considerations, the main objective centers around safeguarding individuals from the dangers posed by toxic gases. The priority during such incidents is always the health and safety of personnel, which underscores the importance of setting boundaries effectively.
