[Chapter 2] Section 2

1. Method of selecting and using fall arrest equipment

1. Select equipment to suit the nature of work

Since the full harness type comes in different variations, select an appropriate type suited to the nature of the work. (See “Full harness types and structures” above)

2. Select equipment suited to the worker’s weight, etc.

A maximum usable weight is specified for fall arrest equipment (85 kg or 100 kg, excluding special-order products). Therefore, select equipment so that the total weight of the person using the equipment and their tools/accessories does not exceed the maximum usable weight.

In addition, characteristics such as size standards and size adjustment points/methods for each strap may differ between manufacturers, so it is necessary to select equipment that suits the user.

[Reference: Applicable size table]

At right is an example of a quick reference chart for finding the approximate size of a harness type safety belt that fits based on the worker’s height and weight.

Avoid use of any size that is significantly too large.

Sizes may differ depending on the manufacturer, so size must be checked when purchasing. す。

3. Wearing fall arrest equipment

Check the instruction manual and make sure the parts necessary for safety are all present.
For the full harness type, wear the equipment snugly and without any looseness so the full harness does not ride up and lose the ability to maintain a safe posture when arresting a fall.
Also, do not remove any parts necessary for safety such as the chest strap.
The body belt type should be worn snugly, as close to the hipbone as possible, at a position where it will not come off toward the feet and will avoid slippage toward the chest as far as possible when arresting a fall.
Buckles should be used correctly, and the end of each belt or strap should be securely passed through the belt loop.
To fasten buckles properly, it is desirable to use a structure that does not allow incorrect fastening, such as a one-touch buckle.
The full harness type usually has two or more buckles, so be careful not to mistakenly fasten them in the wrong combination.
For work positioning equipment, correctly attach the length adjuster to the ring, check the operation of the latch unit, and visually check that belt end and work clothes are not caught.
To prevent the hook, etc. from being mistakenly attached to anything other than the ring during work via work positioning, do not attach any equipment to which the hook, etc. can be attached to the ring or a belt/strap near the ring.
After wearing work positioning equipment, the user should place his/her weight on the equipment under the conditions of use, while still on the ground, and inspect each part to make sure there is nothing wrong.
If fall arrest equipment is not used after its worn, prevent the lanyard from hanging down by attaching the hook, etc. to a ring or putting it in the storage pouch, etc.
Keep the rope of the work positioning equipment from hanging down by attaching it at the shoulder or attaching the hook to a ring and adjusting rope length with the length adjuster.
