Terms Beginning with P

Penstock

A penstock is an enclosed pipe that delivers water to hydroelectric turbines. Penstocks in hydroelectric installations require regular maintenance and inspections which are often well suited to rope access and confined space applications.

Post Job Debrief

The post job debrief is an all employee meeting focusing on: What went well and what could be improved for efficiency, Any near misses or great catches and specific measures to improve safety.

PPE - Personal Protective Equipment

PPE is equipment worn by a worker to minimize exposure to specific occupational hazards. Examples of PPE include respirators, gloves, aprons, fall protection, and full body suits, as well as head, eye and foot protection. Using PPE is only one element in a complete safety program that would use a variety of strategies to maintain a safe and healthy occupational environment. PPE does not reduce the hazard itself nor does it guarantee permanent or total protection.

Probe (Avalanche)

The Avalanche probe, or snowpack probe is a specialized piece of rescue equipment designed to be carried by workers who are exposed to an avalanche hazard and to be used in avalanche search and rescue. The avalanche probe is used in conjunction with the avalanche transceiver and avalanche shovel to quickly and efficiently perform a rescue of a buried worker. Avalanche probes are a tube 2.5m to 3m long which is pushed into the snow and used to pinpoint the location of the buried worker. Often marked with depth increments these devices allow for the utilization of strategic shoveling techniques to increase the overall speed of a rescue. Usually collapsible and made of lightweight materials like aluminum they are designed to be carried by workers in avalanche terrain. Probes are also used for snowpack analysis and in glacier travel to locate snow covered crevasses not visible from the surface.

Prusik Hitch

A prusik hitch is a friction hitch used to put a loop of cord around a rope creating a movable rope grab. The prusik hitch has been used in mountaineering and rope rescue for ascending ropes, building progress capture systems and many other applications since its invention in the 1930’s. It is still used today although modern mechanical rope grabs are becoming more common.
