Personal fall arrest equipment (mandatory)—(1) Scope and also application. This section establishes the applications of and also performance criteria for an individual fall arrest systems which are required for usage by all employees making use of powered communication under chapter 296-870 WAC, powered platforms.
Anchorage. A secure suggest of attachment for lifelines, lanyards, or deceleration gadgets which is capable of withstanding the pressures specified in the applicable part of chapter 296-24 WAC, and independent of the way of supporting or suspending the employee.
Competent person. An individual knowledgeable of loss protection equipment, consisting of the manufacturers recommendations and instructions because that the appropriate use, inspection, and maintenance; and also who is capable of identify existing and potential autumn hazards; and also who has actually the authority to take it prompt corrective activity to get rid of those hazards; and who is knowledgeable that the rules had in this section regarding the erection, use, inspection, and also maintenance of loss protection equipment and also systems.
Connector. A machine which is supplied to pair (connect) parts of the personal fall arrest system and also positioning device systems together. It may be an independent ingredient of the system, such as a carabiner, or it may be an integral component of component of the system (such together a buckle or dee-ring sewn into a body belt or body harness, or a snap-hook spliced or sewn to a lanyard or self-retracting lanyard).
Deceleration device. Any kind of mechanism, such as a rope grab, ripstitch lanyard, particularly woven lanyard, tearing or deforming lanyards, automatic self retracting-lifeline/lanyard, etc., which offer to dissipate a substantial amount of energy during a loss arrest, or otherwise limit the power imposed on one employee during fall arrest.
Deceleration distance. The added vertical distance a fallout’s employee travels, not included lifeline elongation and free fall distance, prior to stopping, from the allude at i m sorry the deceleration an equipment begins to operate. It is measured as the distance in between the ar of one employee"s full body exploit attachment point at the moment of activation (at the beginning of fall arrest forces) that the deceleration device during a fall, and also the ar of that attachment point after the employee pertains to a complete stop.
Equivalent. Different designs, products or approaches to protect against a peril which the employee can show will administer an same or greater degree of security for employees than the methods, products or designs mentioned in the standard.
Free fall. The action of falling before a an individual fall arrest system begins to use force come arrest the fall.
Free autumn distance. The vertical displacement of the fall arrest attachment point on the employee"s human body harness between onset that the fall and just prior to the system begins to apply force come arrest the fall. This distance excludes deceleration distance, and also lifeline lanyard elongation, but includes any kind of deceleration device slide distance or self-retracting lifeline/lanyard extension prior to they operate and fall arrest forces occur.
Full body harness. A configuration of linked straps to distribute a autumn arresting force over at least the thighs, shoulders and pelvis, with provisions because that attaching a lanyard, lifeline, or deceleration device.
Lanyard. A flexible line of webbing, rope, or cable provided to for sure a human body belt or exploit to a lifeline or one anchorage suggest usually 2, 4, or 6 feet long.
Lifeline. A vertical heat from a solved anchorage or in between two horizontal anchorages, independent of wade or working surfaces, come which a lanyard or device is secured. Lifeline as described in this message is one which is component of a fall protection system used as back-up security for an elevated worker.
Personal autumn arrest system. A mechanism used come arrest an employee in a fall from a working level. It is composed of an anchorage, connectors, human body harness and also may encompass a lanyard, deceleration device, lifeline, or suitable combinations the these.
Qualified. One who, by possession the a well-known degree, certificate, or skilled standing, or that by extensive knowledge, training, and also experience, has efficiently demonstrated his/her ability to resolve or resolve troubles related to the subject matter, the work, or the project.
Rope grab. A fall arrester the is designed to relocate up or under a lifeline suspended from a addressed overhead or horizontal anchorage point, or lifeline, to which the belt or harness is attached. In the occasion of a fall, the rope grab locks top top the lifeline rope with compression come arrest the fall. The usage of a rope grab device is restricted for all restraint applications.
Self-retracting lifeline/lanyard. A deceleration an equipment which includes a drum-wound line which might be progressively extracted from, or retracted onto, the north under slight tension during normal employee movement, and also which ~ onset of a fall, instantly locks the drum and arrests the fall.
Snap-hook. A self-closing connecting an equipment with a gatekeeper latch or similar arrangement that will remain closed till manually opened. This includes single action snap hooks the open once the gatekeeper is depression and twin action snap hooks that call for a 2nd action ~ above a gatekeeper prior to the gate can be opened.
Tie-off. The plot of an employee, wearing personal fall security equipment, connecting directly or indirect to one anchorage. That also way the condition of one employee being associated to one anchorage.
(b) Connectors must have a corrosion-resistant finish, and all surfaces and also edges need to be smooth to prevent damages to interfacing components of the system.
(c) Lanyards and vertical lifelines which tie-off one employee must have actually a minimum breaking toughness of 5,000 pounds (22.2 kN).
(d) Self-retracting lifelines and also lanyards which instantly limit complimentary fall street to 2 feet (0.61 m) or less must have components capable of sustaining a minimum revolution tensile pack of 3,000 pounds (13.3 kN) used to the maker with the lifeline or lanyard in the totally extended position.
(e) Self-retracting lifelines and lanyards which perform not limit totally free fall street to 2 feet (0.61 m) or less, ripstitch lanyards, and also tearing and deforming lanyards should be qualified of sustaining a minimum tensile fill of 5,400 pounds (23.9 kN) used to the an equipment with the lifeline or lanyard in the completely extended position.
(f) Dee-rings and also snap-hooks should be capable of maintain a minimum tensile pack of 5000 pounds (22.2 N).
(g) Dee-rings and snap-hooks need to be 100% proof-tested to a minimum tensile fill of 3600 pounds (16 kN) without cracking, breaking, or taking permanent deformation.
(h) Snap-hooks need to be size to it is in compatible v the member come which lock are connected so as to prevent unintentional disengagement the the snap-hook by depression the the snap-hook keeper by the associated member, or should be a locking kind snap-hook designed and also used to protect against disengagement of the snap-hook by the contact of the snap-hook keeper by the linked member.
(i) Horizontal lifelines, wherein used, have to be designed, and installed as component of a complete an individual fall arrest system, i m sorry maintains a safety factor of at the very least 2, under the supervision the a default person.
(j) Anchorages come which personal fall arrest equipment is attached need to be capable of sustaining at the very least 5,000 pounds (22.2 kN) per employee attached, or should be designed, installed, and used as component of a complete personal fall arrest device which maintains a safety variable of at least two, under the supervision that a standard person.
