# How do you find the horizontal lifeline?

## How do you find the horizontal lifeline?

The installer or supplier of the horizontal lifeline system, has to take into account the following variables when calculating a lifeline system:

1. The surface on which the HLL is mounted.
2. The distance between the anchor posts.
3. The height of the anchor posts.
4. The tension of the anchor line.

## How many workers can tie to a horizontal lifeline?

HLL capacities vary by manufacturer, but a common HLL capacity is two workers in fall arrest and four workers in fall restraint.

What are the two requirements for a horizontal lifeline?

Installation of Horizontal Lifeline Systems Temporary and permanent horizontal lifeline systems require user equipment such as a full body harness, a shock-absorbing lanyard, or an anti-ratcheting self-retracting lifeline, to ensure 100% fall protection at all times.

How long is a horizontal life line?

60 ft.
2.1 HORIZONTAL LIFELINE SPAN: The maximum horizontal lifeline span length is 60 ft. (18.3 m). The system length can be extended by using Intermediate Stanchions to create multiple spans (see Figure 1). The span length must be reduced when clearance is limited (see Figure 5 and Figure 6).

### What should be an angle of Life Line?

The maximum installation inclination of the system should be 15º including the angle of attack to the intermediate points. A prior study of the best layout must be carried out so that the user can access the system safely.

### What is the thickness required for a wire rope lifeline?

A lifeline must be wire rope of at least ½ inch (1.20- centimeter) diameter, not more than two persons shall be permitted to attach their lanyards to a single horizontal life line, at one time.

How many anchor points should a horizontal lifeline be connected to?

two anchor points
Components of a horizontal lifeline The system consists of a wire rope which is attached to at least two anchor points.

How do horizontal lifelines work?

At their most basic, horizontal lifelines incorporate a simple fiber or wire rope connected to a series of anchor points. A shuttle runs along the length of the rope, and workers connect to the shuttle using a lanyard and hook, in order to safely move along the line.

#### What is the safety factor for a horizontal 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.

#### How does a horizontal lifeline work?

Which line is life line in hand?

The life line is one of the five main lines read in palmistry. It extends around the thumb. The life line is usually in an arc around the base of the thumb, starting between the index finger and the thumb and ending near the wrist.

What is the minimum diameter of lifeline?

## What is minimum length of the lifeline?

Lifelines must be a minimum of 3/4 inch manila or equivalent, with a minimum breaking strength of 5,400 pounds. Occupational Safety and Health Administration.

## Do horizontal lifelines have to be engineered?

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.

How do you convert free fall to minimum?

Self-retracting lifelines and lanyards that automatically limit free fall distances to 2 feet (0.61 m) or less shall be capable of sustaining a minimum tensile load of 3,000 pounds (13.34 Kn) applied to a self-retracting lifeline or lanyard with the lifeline or lanyard in the fully extended position.

What is the maximum length between two secure points of a wire rope life line?

60 feet
Maximum distance between two anchor points cannot exceed 60 feet. If the work area to be traveled exceeds 60 feet intermediate support of the lifeline is required.
