Final answer:
The RIC UAC is a standard fitting on firefighter SCBA gear that allows intervention teams to replenish air supply for individuals in distress without removing their equipment.
Step-by-step explanation:
The Rapid Intervention Crew/Company Universal Air Connection (RIC UAC) is a system used by firefighters to provide an external connection to an intervention team's air supply. This connection allows for the replenishment of air to a downed or trapped firefighter without the need to remove their personal self-contained breathing apparatus (SCBA). The RIC UAC is typically a standardized fitting that can be found on firefighter SCBA equipment, allowing for compatibility and ease of use across different departments and units when a rapid intervention is necessary.
