What is a formal RIT crew established to replace?

A formal Rapid Intervention Team (RIT) crew is established to specifically take over the responsibilities of the Immediate Rescue Intervention Crew (IRIC) team. The IRIC is typically a temporary measure designed to provide immediate support if firefighters become endangered or trapped. However, as the situation evolves, the RIT takes over for a more structured and dedicated response aimed at ensuring the safety of personnel operating within the hazardous environment.

RIT crews are trained specifically for the purpose of rescuing downed or trapped firefighters, and they follow a set protocol for their operations. By formally recognizing the RIT's role, it allows incident commanders to maintain an organized and efficient approach to firefighting operations while ensuring that specialized rescue personnel are available if a situation arises that requires immediate response to a safety emergency. This approach improves the overall safety of all personnel involved by ensuring that dedicated resources are always on hand to perform rescues if necessary.

The other options do not directly relate to the specific role and function of a RIT crew, which is focused on rescue operations rather than command, safety oversight, or overall incident management.
