1 LOWERING

2 HIGH ANGLE LOWERING OBJECTIVES: DISCUSS ELEMENTS OF A HIGH ANGLE LOWERING SYSTEM. SELECT EQUIPMENT MEDICAL CONSIDERATIONS FUNCTION OF FOLLOWING POSITIONS: LITTER TENDER,BRAKEMAN,ROPE HANDLER,BELAYER AND EDGE TENDER NEED FOR REALIABLE COMMUNICATIONS

3 TERMS AUXILIARY TENDER: THE PERSON WHO RAPPELS ALONGSIDE THE LITTER AS IT BEING LOWERED IN ORDER TO ASSIST IN THE RESCUE. BRAKEMAN: THE PERSON WHO OPERATES THE BRAKING DEVICE FOR CONTROLLING THE RATE OF DESCENT OF THE LOAD. DOUBLE STRAND LOWERING: THE USE OF TWO ROPES ATTACHED TO THE LITTER IN A LOWERING LITTER RIGGED. DOUBLE STRAND LOWERINGS USUALLY INVOLVED TWO LITTER TENDERS.

4 TERMS EDGE TENDER: THE PERSON CONNECTED TO A SAFETY ATTACHMENT WHO WORKS AT THE EDGE. LOAD: THE OBJECT / PERSON BEING LOWERED BY ROPE IN A HIGH ANGLE LOWERING. PIG TAIL: A SHORT PIECE OF ROPE WITH WHICH THE LITTER TENDER ATTACHES TO THE LITTER SYSTEM. SINGLE STRAND LOWERING: THE USE OF ONE MAIN LOWERING ROPE WITH A BELAY IN LITTER LOWERING. SPIDER: THE SYSTEM OF ATTACHING A LOWERING ROPE TO A LITTER.

5 THE HIGH ANGLE LOWERING HIGH ANGLE LOWERING IS ALSO SOMETIMES CALLED VERTICAL LOWERING OR TECHNICAL LOWERING. IF THE SUBJECT`S INJURIES ARE SEVERE ENOUGH,THE LOWERING IS DONE WITH THE SUBJECT PACKAGED IN A LITTER. IN SOME CASES WHERE THE SUBJECT IS UNINJURED OR ONLY SLIGHTLY INJURED, IT MAY BE POSSIBLE TO LOWER HIM WITHOUT THE LITTER, BY ATTACHING HIM TO A RESCUER.

6 SOME OF THE ENVIRONMENTS IN WHICH A HIGH ANGLE LOWERING MIGHT BE EMPLOYED INCLUDE: CLIFFS BUILDINGS OTHERS STRUCTURES SUCH AS CRANES,TOWERS,STACKS,OR SILOS VERTICAL CAVES
