Helmet for work at height and rescue
This document only applies to technical information for the
helmet. For technical information on the DUO LED 14 headlamp,
consult the attached Instructions for use for the DUO LED 14
headlamp.
Field of application
This helmet is designed only for work at height and rescue.
This helmet meets all requirements of the EN 397 standard,
except for the chin strap. The chinstrap has a strength of 50 daN
(requirement of the EN 12492 standard) to help keep the helmet on
the head in case of a fall.
This helmet meets optional requirements of EN 397: protection
against impacts down to -30 °C, resistance to lateral deformation
and protection against molten metal splash.
This helmet does not provide protection against electrical risks.
Do not use this helmet in activities for which it is not designed.
Activities at height present a risk of serious head injury. Wearing
a helmet can significantly reduce this risk, but cannot entirely
eliminate it.
In a major impact, the helmet deforms to absorb the maximum
amount of energy possible, sometimes to the point of destroying
the helmet.

Inspection, points to verify
Before each use, check the condition of the shell and the headband
attachment system (verify there are no cracks or deformation on
the outside or the inside...). Check the condition of the webbing and
stitching. Verify that the headband adjustment system and chinstrap
buckle are functioning properly.
WARNING, a major impact to the helmet can significantly reduce its

Consult the details of the inspection procedure to be carried out for
each item of PPE on the Web at www.petzl.com/ppe
Contact PETZL if there is any doubt about the condition of this
product.
Instructions for use
1. Preparation
Use only the smooth areas for stickers and other markings. PETZL
stickers are approved. Do not apply paint, solvents, adhesives
or self-adhesive labels, except those recommended by PETZL
instructions.
2. Adjustments
2a. Adjust the headband to maximum size using the adjustment
wheels and place the helmet on your head.
2b. Position the adjusters under the ears. To adjust the chinstrap
backwards or forwards, slide the webbing through the chinstrap
positioning buckles.
2c. Use the adjustment wheels to increase or decrease the size of
the headband. You can adjust the height of the headband on your
forehead (two adjustment holes for the vertical position of the
headband).
2d. Fasten the chinstrap using the buckle. You must hear the buckle
"click" to ensure proper fastening. Tighten the chinstrap, it should
be snug, but comfortable. A correctly adjusted chinstrap reduces the
risk of the helmet coming off accidentally.
You must pull on the chinstrap to verify that the buckle is
properly fastened.
To open the buckle, press the button on the chinstrap fastening
buckle.
2e. Adjust the vertical position of the headband adjustment system
on your nape by sliding it up or down along the webbing.
TECHNICAL NOTICE VERTEX BEST DUO 1
ATTENTION, be sure there is no slack in the webbing between the
headband adjustment system and the shell of the helmet.
3. Test
Verify that the helmet is well seated and centered on the head. A
well-adjusted helmet (minimal movement front to back or side to
side), provides better protection.
Accessories
- Use the side slots to attach hearing protection. Use a screwdriver
to remove them.
- Mounting the face shield: use the face shield mounting hole, or the
side slots.
Precautions for use
- Your helmet can be damaged from improper care. Do not sit on
it, pack it too tightly, drop it, allow it to contact sharp or pointed
objects, etc.
Do not expose your helmet to high temperatures, for example by
leaving it inside a vehicle in direct sunlight.
- Certain chemical products, especially solvents, can damage your
helmet. Protect your helmet from exposure to chemicals.
- This helmet has been tested for use at temperatures between
-30 °C and +50 °C.
