What does the "Two In / Two Out" rule require?

The "Two In / Two Out" rule is a critical safety procedure designed to protect firefighters during operations in potentially hazardous environments, such as structure fires. This rule stipulates that two firefighters must enter a dangerous area, such as a building that is on fire, while at least two additional firefighters remain outside to provide support and initiate a rescue if necessary. This approach ensures that there is always a team ready to respond to emergencies, enhancing the safety of personnel involved in firefighting operations.

The emphasis on having a minimum of two firefighters both inside and outside reflects the importance of teamwork and mutual support, which are essential for maintaining safety during high-risk situations. This rule is especially pertinent in situations where rescuing a downed firefighter may be required. Implementing the "Two In / Two Out" rule helps to minimize risk and reinforces safety protocols within fire departments.

The other options do not accurately reflect the intent or requirements of the "Two In / Two Out" rule.
