  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.

  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
