Rescue life air bags are specialized equipment used by firefighters and rescue teams to lift heavy objects or vehicles in emergency situations. The statement that you must crib as you lift is true because cribbing provides necessary stability and support after the lift has commenced. While the air bags can lift heavy loads by providing a substantial amount of force through air pressure, they need a solid and secure base to work effectively. Cribbing ensures that once the load is lifted, it remains stable and does not shift or fall back due to unforeseen circumstances.
The importance of cribbing lies in its ability to counteract the potential hazards of relying solely on air bags, which can inadvertently collapse if not supported properly. This practice enhances safety for both the rescuers and the victims by providing multiple layers of support and preventing any accidents during the lifting process.
In contrast, the other statements are misleading. Air bags do require additional support, training is essential for safe and effective use, and their performance may be affected by various weather conditions. Proper training equips operators with the knowledge to deploy and use rescue life air bags appropriately, ensuring safety.
