What is the primary goal of the "two-in, two-out" rule?

The primary goal of the "two-in, two-out" rule is to ensure that a backup team is ready outside a hazardous area. This safety protocol mandates that when two firefighters enter an IDLH (Immediate Danger to Life and Health) environment, there must be at least two firefighters stationed outside who are prepared to initiate a rescue if needed.

This rule emphasizes the importance of safety and risk management during firefighting operations. By having a dedicated backup team, the safety of rescuers is prioritized, ensuring that if something goes awry inside the hazardous area, there are personnel available outside to provide immediate assistance. This strategic approach not only protects the lives of firefighters but also reinforces the idea that no one should operate alone in dangerous situations without adequate support.

The other options, while they address various aspects of incident management, do not capture the essence of the "two-in, two-out" rule's commitment to firefighter safety and effective rescue abilities.
