- The document provides guidance on equipment and regulations for working at heights, with a focus on situations for electricians. It outlines regulations requiring fall protection anytime a risk of falling exists. - Descriptions and standards are given for various pieces of personal protective equipment for working at heights, including fall arrest harnesses, lanyards, energy absorbers, rope grabs, and full kits. Proper anchoring points, calculations for sufficient headroom, and inspection procedures are also discussed. - Examples illustrate equipment setups for different situations like poles, posts, and rail/tramway work. Complete equipment kits are offered containing all necessary gear for compliance. Regulations aim to prioritize collective protection but require personal protective

2. Work at heights is the second cause of work accidents with almost 100,000 falls per year, 100 of which
are fatal and 8,500 causing permanent incapacity.
The electricity sector is especially involved in a significant amount of work carried out
on high structures as varied as high voltage pylons, catenary structures or roofs,
whether they are on industrial buildings or on residential housing.
This guide by CATU covers the 6 most representative situations of work carried out
by electricians and the necessary equipment that is compliant with the applicable
standards. A full kit containing all the equipment required for each situation has been
produced to equip you in full compliance with the latest applicable laws.
What the regulations stipulate for work at heights:
* Decree no. 65-48 of 8 January 1965
Protection must be given against falls from a height of over 3 m.
* European directive of 1989, amended in 1993 and 1996 "Approximation of the laws of member states
relating to personal protective equipment"
"The national provisions relating to safety at work make the use of personal protective equipment compulsory; many requirements oblige employers to make appropriate personal protective equipment available to their staff in the absence or inadequacy of priority public protection measures."
"adoption of harmonized standards"
The CE marking is mandatory for all PPE compliant with the standards in force.
* Decree no. 92-766 of 29 July 1992: Enforcement decree of the 1989 European directive
* Decree no. 2004-924 of 1 September 2004: "decree relating to the use of work equipment made available for temporary work at heights... »
- The priority is the installation of collective protective equipment. When this is not possible, recourse to
an item of personal protective equipment against falls from a height is required, whether this is for the
purposes of retaining, support, saving, or protecting against falls from a height.
- Removal of the minimum height of 3 m: after a risk evaluation, protective equipment is required as
soon as there is a risk of a falling.
- A worker must never remain alone so that he can be assisted in a time compatible with the preservation
of his health.
- The work at height must never be conducted when the weather or environmental conditions of the work
place may compromise safety.
- The use of access and positioning techniques by means of ropes must comply with the following: a working rope, a safety rope fitted with a fall arrestor system, with two separate anchoring points. Workers must
be provided with suitable fall arrestor harnesses connected to both ropes. Safe descent/mounting systems with a self-locking system and a mobile fall prevention system must be provided.
- The work must be programmed and supervised so that assistance can be given immediately to the worker in the event of an emergency.
- The workers must receive suitable and specific training in the operations considered and in the
rescue procedures.

Definitions and recommendations:
Fall arrest system
Comprising a fall arrest harness, a linking equipment (lanyard, fall arrestor
device, connector, etc.) and an anchoring point.
Information on the dangers of a fall
A body experiences high pressure when falling. The permissible force of
impact by a man with a harness is 600 daN (approx. 600 kg). A force
< 600 daN does not produce significant injuries, in contrast with a force
> 600 daN that leads to serious or even fatal injuries.
(see EN 363 Fall arrestor).
Recovery procedure
A procedure must be established in the event of a fall to be able to recover
the person:
in the event that someone falls wearing a harness, an unconscious person
can remain so for 10 to 20 minutes, after this, there is a risk of irreversible
injuries (tourniquet, blood not oxygenated, etc.).
Headroom
The headroom must always be calculated to choose the equipment carefully.
This clearance distance is the space necessary under the user so that he will
not encounter any obstacle during a fall (see diagram opposite).
Pay attention to correctly note the increase in fall arrest for calculating the
headroom (max. 1.75 m) - specified on the product.
Anchoring point
For limiting the fall risk factor, you must always try to have an anchoring point
above the worker's head, or at least on the same horizontal plane. An
anchoring point under the user is more dangerous, and requires a larger
headroom.
P.P.E checks (personal protective equipment)
Once a year at most by an inspector, namely a trained and qualified person
within the company, or an inspection agency.
User manuals
Always read the equipment user manuals before using the equipment.

If height > than 5.5 m the

there is a hazards and another method must be considered.
Comment:
In general, the anchoring
point must be above the person or on the same horizontal plane.
