Helmets
18.6.1.
Condition of the Outside of the Shell
The inspection of the helmet starts with the check of the condition of the outside of the shell. On the upper part, look for evidence
of impact, cracks, or burns, as well as any signs of damaged caused by chemicals. Do the same around the base of the shell.
18.6.2.
Condition of the Inside of the Shell
Check the condition of the inside, paying more attention to the base, particularly the reinforcement. Check that none of the ridges
are broken or deformed. Then make sure that there are no cracks, marks or deformities on the sides.
18.6.3.
Condition of the Cradle
Check the headband by feeling to ensure that the stiffness has not been lost and there are no broken zones. Inspect all the
webbing straps for any trace of wear, cuts or burning. Do not hesitate to move the retaining loops and the plastic buckles to look
at all parts of the webbing straps. Then check that the stitching of the straps is not cut or distorted. Finally check the main
fastening buckle, the sliders and the plastic components.
18.6.4.
Condition of the Cradle Fixings
Ensure that the adjustment wheels do not slip. Check the headband fixings level with the two clips and two rivets. Then check
the four fixing-points of the cradle.
18.6.5.
Condition of the Padding of the Headband
If the padding is torn or very dirty, you can replace it.
18.6.6.
Condition of the Headlamp Clips
Check that the headlamp fixing clips are present and in good condition.
18.6.7.
Operation of the Headband Adjustment
Use the adjustment wheel to tighten the headband as far as possible, and then pull the headband to check that it
does not loosen. If the adjustment does not work, the product must be rejected. Warning, do not pull the headband
too hard, the purpose of this test is not to check the strength of the adjustment.
18.6.8.
Operation of the Nape of the Neck Adjustment
Operate the adjustment wheel to check that the rack mechanism works, then pull on the webbing and check that it does not
loosen. Warning, do not pull the webbing too hard, the purpose of this test is not to check the strength of the rack mechanism.
Operation of the Fastening and Unfastening of the Chin Strap and its Adjustment
Open and then close the buckle. Check that it is well fastened. This is not a test of the strength of the buckle. According to the
helmet model, the chin strap buckle may release between 15 and 25 kg (EN 397 industrial helmets) or it may release between 50
kg (mountaineering and other helmets). These values correspond to the requirements of the standard, or to specific technical
requirements. Check the adjustment. If the strap cannot be adjusted, clean the webbing. For your safety and comfort, the
helmet must always be perfectly adjusted.

Lanyards

Type of Lanyard
Two types of lanyard exist; lanyards constructed entirely from textile materials and textile lanyards with metallic
devices.
18.7.2.
Condition of the Rope/Condition of the Webbing
Carry out a visual inspection of the sheath to detect cuts, a fluffy appearance, or burns. Then carry out an inspection by touch to
find hard or soft points. If you find one of these points, alter the position of the rope, the curve must be regular. Move rope
protectors and other devices in order to check hidden parts. Carry out the same inspection with webbing components.
