REACH |
In order to safeguard the consumers' health, the European Union issued the Reach regulation (come into force on 1st June 2007) which forbids the use of certain chemicals. COFRA guarantees the compliance of all its products with the REACH regulation; they do not contain carcinogen substances or mentioned in the European list of forbidden substances and, in order to grant it, all raw materials used during production are subjected to controls. |
COFRA branded body harnesses and work positioning belts, belonging to the category of personal protective equipment for work positioning and the prevention of falls from a height, have been designed and developed entirely by COFRA technicians based on in-depth and extensive engineering and marketing research, with the aim of offering the end-user the highest standards of quality and reliability. They are fully guaranteed by certifications and comply with all current regulations on fall protection. The two key tests performed on body harnesses are the static test and the dynamic test.
STATIC TEST | |
---|---|
The test torso and harness are placed in the testing rig and a force of 15 kN is applied between the fastening element of the harness and the lower ring of the test torso. The same test is repeated applying a force of 10 kN between the fastening element of the harness and the upper ring of the test torso. The static force applied is maintained for 3 minutes after which checks are made to ensure that the harness has not become detached from the test torso. The test is performed for each fastening element on the harness. |
|
DYNAMIC TEST | |
The harness is fitted onto the test torso and secured to the rig with a lanyard. The torso is allowed to fall feet first for approximately 4 m before the lanyard becomes taut; using the same lanyard, the test is repeated immediately, allowing the torso to fall head first for approximately 4 m. After each fall, checks are made to ensure that the harness has not become detached from the torso and that the angle of inclination between the longitudinal axis of the torso’s dorsal area and the vertical axis does not exceed 50°. Both phases of the dynamic test are applied to each attachment point designed for fall arrest and bearing the relative marking. |

The size chart is only an indicative instrument to select the size. Each person has his/her own body shape, therefore before any use it is always necessary to wear the harness in compliance with the procedures indicated in the informative note. It should be remembered that the harness must be adjusted so that it is close-fitting to reduce the injury risk in case of fall. It is important to make with its own equipment some movements and a suspension test on each dorsal and sternal anchorage point, to be sure that the size is correct, that it is comfortable enough for the recommended use and that the adjustment is fine.
HIGH-TENACITY |
The strap is made of high-tenacity polyester making it highly resistant to tear and abrasion.
|

---|---|---|---|
KERNMANTLE |
The static rope with kernmantle weave is characterised by a composite structure comprising a stress-resistant inner kern and an outer mantle to protect the kern from abrasion, UV rays, weather conditions, oil, fire and heat. In addition, the mantle acts as a visible indicator of the rope’s wear.
|
||
STEEL |
Steel resists perfectly to the considerable stresses which develop during a fall. All steel components have undergone anticorrosive galvanisation treatment with zinc or chrome.
|
||
ALUMINIUM |
Aluminium is a very light metal offering the same mechanical performance as steel. It resists the considerable stresses which develop during a fall. All aluminium components have undergone anticorrosive anodization treatment.
|
||
SCREW LOCK |
Screw lock closure is the simplest locking mechanism while maintaining a high level of safety. |
||
TWIST LOCK |
TWIST LOCK closure improves safety in the work zone with automatic closure of the lever. |
||
TWIST-UP LOCK |
TWIST-UP LOCK closure further improves safety in the work zone with automatic closure of the lever and added slide release. |
||
KEY-LOCK |
KEY-LOCK closure is designed to avoid the need for locking rivets to close the carabiner; this makes the device functional and means that the rope cannot be snagged when the carabiner is being closed. |
ELASTYX |
ELASTYX technology successfully introduces the concept of a strong weave elasticated strap offering unrivalled fit and comfort, as well as exceptional freedom of movement thanks to the interweaving of high-tenacity polyester and elastane, while maintaining high resistance to tear and abrasion performance.

QUICK-RELEASE BUCKLES |
Quick-release buckles offer the user fast and easy locking while maintaining high resistance to stresses.
|
||
PERSPIREX |
PERSPIREX technology successfully introduces the concept of perforated sponge material offering the user a high level of breathability with exceptional body grip and guaranteed comfort.
|
||
LOOP TOOL |
The loop tool carrier offers the user easy and accessible storage of work tools when they are not in use.
|
||
REVERSE-D |
Thanks to REVERSE-D technology, attachment points can be folded away and closed at any time, and whenever they are not needed. The ability to shut away attachment points prevents the user from remaining accidentally stuck or caught on protrusions and dangerous snags. |
||
CONNECTOR |
The connector with ergonomic handle is designed to give unrivalled hold and greater ease of use. |
||
SWIVEL |
The SWIVEL system prevents the strap from twisting around itself, avoiding the sudden blockage of the device and enabling the user to work with complete freedom of movement. |
||
FALL |
The fall indicator improves the user’s safety by displaying whether or not the device can still be used. |
||
EXTREME LOAD |
The additional test regulated by VG 11 CNB/P/11.062 certifies the resistance of COFRA retractable devices at a maximum nominal load of 150 kg, compared with the 100 kg of other retractable devices on the market, certified according to current base standard EN 360. |
Personal protective systems against falls from a height protect the user against falls from a height by preventing or arresting falls. In particular:
Fall arrest is the action which prevents the user from hitting the ground, a structure or other obstacles during a fall.
Fall prevention is the action which stops the user from approaching an area where there is a risk of falling.
Work positioning is the action which allows the operator to work tensioned or suspended in a way that avoids falls.
A personal protective system against falls consists of an assemblage of components which are either permanently connected to each other or can be separated. It is comprised of: body harness, secure anchorage point and connection system.
FALL ARREST SYSTEM |
---|
A system that arrests falls and limits the impact force on the body of the user during fall arrest.
The main characteristics of a generic fall arrest system are as follows: In particular, a fall arrest system includes: body harness, secure anchorage point and connection system. |
RESTRAINT SYSTEM |
A system which prevents falls from a height by limiting the user’s movement. The main characteristics of a generic restraint system are as follows: A restraint system must be assembled in such a way as to prevent the user from reaching areas or positions where there is a risk of falling from a height. Any suitable body harness and any suitable lanyard may be used. In particular, a restraint system includes: body harness, secure anchorage point and connection system. |
WORK POSITIONING SYSTEM |
A system which allows the user to work tensioned or suspended in a way that avoids falls. The main characteristics of a generic work positioning system are as follows: |
The personal protective system against falls from a height consists of an assemblage of connected components; for the system to work correctly certain essential factors must be taken into consideration, such as the clearance, the fall factor and the pendulum effect, and how they interact with each other. The assessment of these factors determines which components should be assembled to give adequate protection.

PENDULUM EFFECT |
The dangerous oscillation the user would be subjected to if the anchorage point is not fixed vertically with respect to the actual position of the user. Such lateral oscillation could expose the user to dangerous collisions with close obstacles of different kinds, causing a range of injuries. Often, given the nature of the work zone, it is not possible to secure an anchorage point vertical to the position of the user; in this case oscillation can be prevented by using to different anchorage points situated on both sides of the user. |
FALL ARREST |
Fall arrest devices are employed simultaneously in order to prevent the injurious fall to the ground of the user. |
