This litter is designed for use in mass casualty incidents where terrorists using Weapons of Mass destruction, mass casualty evacuation from hospital or other building or any other Haz-Mat incident requiring level A protection occur. The HMH Sked is extremely versatile. It can be dragged over virtually any terrain including stairways. It requires less effort from rescuers wearing level A protection. Patients can be rolled or dragged onto the HMH Sked rather than lifting. This creates less rescuer fatigue and allows many more victims to be saved. A downed rescuer can be roll loaded by using his air tank for leverage and evacuated before the standby rescuers can zip up and be duct taped. This allows his rescue without committing the standby team.
