What is the safety factor for lifeline?
two
“Horizontal lifelines shall be designed, installed, and used, under the supervision of a Qualified Person, as part of a complete personal fall arrest system, which maintains a safety factor of at least two.”
What are the two types of lifelines?
There are two types of lifelines, vertical and horizontal. A vertical lifeline typically holds only one employee. The lanyard moves with the employee, and will hang vertically in the event of a fall. A horizontal lifeline connects to anchorages at both ends to stretch horizontally.
What is the capacity of lifeline?
Some lifelines have a minimum breaking strength of 5,000 to 11,000 pounds and a capacity of 310 pounds (ANSI) and 400 pounds (OSHA). All lifelines should meet OSHA Regulations 29 CFR 1910.66 and 1926.502.
What is the thickness of Life Line?
Lifeline wire has traditionally been available in 1/8″ and 3/16″ wire diameters, with a soft but durable vinyl coating increasing the effective diameters to 7/32″ and 5/16″ respectively.
What is the minimum diameter of lifeline?
Lifelines used on rock-scaling operations, or in areas where the lifeline may be subjected to cutting or abrasion, shall be a minimum of 7⁄8 -inch wire core manila rope. For all other lifeline applications, a minimum of 3⁄4 -inch manila or equivalent, with a minimum breaking strength of 5,000 pounds, shall be used.
What is the thickness of lifeline?
Lifeline wire has traditionally been available in 1/8″ and 3/16″ wire diameters, with a soft but durable vinyl coating increasing the effective diameters to 7/32″ and 5/16″ respectively. It should be inspected on an annual basis for signs of corrosion or breakage of wire strands.
Which rope is used for lifeline?
Nylon, polyester, polypropylene, and polyethylene are common materials used when making rope. For lifelines, nylon, polyester, and a polypropylene/polyethylene blend are good, but rope made of only polypropylene is not. Nylon is a good choice for a lifeline because of its strength and durability.
What are the safety requirements for lifelines?
Lifelines must not be made out of natural fiber rope. Polypropylene rope must have an ultraviolet (UV) light inhibitor. When used as fall protection, all lifelines must be protected from being damaged e.g. cut, melted, abraded, etc.
When is a lifeline system suitable for fall protection?
Not every situation is suitable for guardrailing. In circumstance where a fall cannot be prevented, fall protection lifeline systems are your next line of fall protection. Lifeline systems can be used to arrest workers in the event of a fall (active system), or restrain workers from reaching a fall hazard (restraint).
What is a lifeline and how does it work?
A lifeline is a component of a personal fall protection system consisting of a flexible line and is used to mitigate falls while working at height. Lifelines, when properly anchored, can prevent a fall from occurring or in the event that the fall has already happened, can arrest or stop the person mid-fall, prior to them reaching the ground.
What is a self retracting lifeline line OSHA?
OSHA 1910.140 (b) defines a self-retracting lifeline/lanyard as “a deceleration device containing a drum-wound line that can be slowly extracted from, or retracted onto, the drum under slight tension during normal employee movement, and which, after onset of a fall, automatically locks the drum and arrests the fall.”
