Question | Answer |
---|---|
Load Releasing Hitches (LRH) | Often placed in line with TPB systems to release a bound and loaded prusik |
Vector definition | Changing the primary rope system by pushing down, lifting up or pulling it to the side in order to place the load on the primary system |
Single Line Lowering System definition | Employs one rope attached to an object to be lowered, usually either a harness or a litter |
Rappel system difference from a lowering system? | Rappel system uses an anchored (fixed rope) with a traveling brake (the descent control device) |
Lowering system difference from a rappel system? | Lowering system uses an anchored (fixed brake) with a traveling rope (the lowering line) |
What are the manpower requirements a single line lowering system? | 4 man team (a team leader, brakeman, tag man and belay man) |
Team leader definition | Responsible for having system checked before allowing life loading and communicating with the brakeman for lowering operations |
Brakeman definition | Person operating the descent control device |
Tag man definition | Person responsible for operating tag lines to keep lead from contacting obstacles or projections |
Belay man definition | Responsible for minding the belay system |
What are the atmospheric hazards? | Oxygen enrichment, flammability and toxicity die to introduced products or materials (TICs/TIMs) |
Rescue definition | Initial response, in an all-out effort, to conduct lifesaving operations |
Recovery definition | Patient survivability is deemed to low and where the risk to rescue personnel is deemed too high |
Rigid litter definition | Basket or stokes litters usually made of structural metal or combinations of metal and plastic components |
Flexible litter definition | Made of flexible high-tech plastic components which allow the victim to be reduced to his or her lowest profile for passing through narrow openings (SKED) |
Mechanical Advantage definition | Simply a way of reducing the amount of force required to lift a load and usually expressed in ratio the weight of the load as compared to the force required to lift it |
What are the two types of Mechanical Advantage Systems? | Simple and compound systems |
Simple rope/pulley definition | a rope mechanical advantage system containing a single rope and one or more moving pulleys |
Progress Capture Device (PCD) | This device is nothing more than a rope grab placed in the system to act as a progress capturing device |
Compound MA systems definition | A system created by stacking the load end of one or more simple systems onto the haul line of another to multiply the forces created by the individual simple systems |
