3. Inspection, points to verify
Your safety depends upon the integrity of your equipment. Petzl recommends a
detailed inspection by a competent person at least once every 12 months
(depending on current regulations in your country, and your conditions of
usage).
WARNING: your intensity of use may cause you to inspect your PPE more
frequently. Follow the procedures described at Petzl.com. Record the results
on your PPE inspection form: type, model, manufacturer contact info, serial
number or individual number, dates: manufacture, purchase, first use, next
periodic inspection; problems, comments, inspector’s name, and signature.
Before each use
Check the webbing at the attachment points, at the adjustment buckles, and at
the safety stitching. Look for cuts, wear and damage due to use, to heat, to
chemicals… Be particularly careful to check for cut or lose threads. Verify
that the DOUBLE BACK and FAST LT buckles function properly.
During use
Regularly verify that the adjustment buckles are securely fastened. It is
important to regularly monitor the condition of the product and its
connections to the other equipment in the system. Make sure that all items of
equipment are correctly positioned with respect to each other.
4. Compatibility
Verify that this product is compatible with the other elements of the system
in your application (compatible = good functional interaction). Equipment used
with your harness must meet current standards in your country (e.g. EN 362
carabiners).
5. Harness setup
– Be sure to correctly stow the excess webbing (folded flat) in the elastic
keepers. – Beware of foreign objects that could impede the operation of the
FAST LT buckles (e.g. pebbles, sand, clothing…). Verify that they are
correctly fastened (see diagrams).
Adjustment and suspension test
Your harness must be adjusted to fit snugly in order to reduce the risk of
injury in case of a fall. In a safe environment, you must move around and hang
in the harness from each attachment point to verify that the harness provides
adequate comfort for the intended use and that it is optimally adjusted.
6. EN 358: 2018 belt for restraint and work positioning
These attachment points must only be used to attach to the restraint or work
positioning system – maximum fall height: 0.6 m.
See the Instructions for Use of the lanyard used, for usage precautions.
Do not use a work positioning belt if there is a foreseeable risk of the user
becoming suspended or exposed to uncontrolled tension on the belt.
For work positioning, use an anchor point situated at or above waist level.
These attachment points are not designed for fall-arrest usage.
It may be necessary to supplement work positioning or travel restraint systems
with collective or personal fall-arrest systems.
When used in a fall-arrest system in accordance with the EN 363 standard, use
a TOP – TOP CROLL (old version), TOP – TOP CROLL S, TOP CROLL L (2018 version)
or CHEST’AIR together with your seat harness.
The waistbelt is approved for one user, including his/her tools and equipment,
for a maximum total weight of 150 kg.
6A. Ventral attachment point
6B. Waistbelt side attachment points
Always use the two side attachment points together, by linking them with a
positioning lanyard, in order to be comfortably supported by the waistbelt.
6C. Rear restraint attachment point
This rear waistbelt attachment is designed only for attachment of a restraint
system to prevent the user from entering an area where a fall is possible.
7. EN 813: 2008 seat harness
Ventral attachment point Designed for progression on rope and work
positioning. Use the ventral point (textile or metal) to attach a descender,
positioning lanyards, progression lanyards, or the PODIUM seat. This
attachment point is not suitable for fall arrest.
