WARNING!
ANSI/ISEA Z89.1 and CSA Z94.1 Class E and G, and EN 50365:2002 Class 0 helmets are designed
to supply limited protection from electrical shock by preventing the passage of electrical current
through the user's head and body. Do NOT use this helmet alone. Use other insulating protective
equipment that is applicable to the risk related to the activity. Make sure that the nominal voltage that
will occur during helmet use is not more than the electrical limits of the helmet.
ANSl/ISEA Z89.1 and CSA Z94.1 Class C helmets do not supply electrical protection.
The following conditions for safe use must be observed for Electrostatic-INERIS helmets:
- To make sure of the good flow of the electrostatic charges, it is imperative that the electric continuity
is assured between the helmet and the earth by a contact with the skin.
- The Personal Protection Equipment must be used with a conductive ground or a dissipator of
electrostatic charges and shoes with a resistance lower than 1.10^8 ohms.
- The operator must use a complete "antistatic" PPE adapted for use in ATEX zone (type jacket and
pants).
Failure to obey these warnings can result in serious injury or death.
V-Gard H1 non-vented helmets are Class E. V-Gard H1 vented helmets are Class C.

Adjusting the Suspension
WARNING!
To supply maximum protection, make sure that the helmet is in the center position on your head and
the fit is tight. Do NOT keep gloves, cigarettes, earplugs, or other objects between the suspension and
the shell. Objects in this space can transmit a large amount of force to the head and neck during impact
and result in serious injury or death. Failure to obey these warnings can result in serious injury or death.
See Figure 1.

Adjusting the Chin Strap
WARNING!
If using hearing protection, ensure that the chinstrap does not interfere with the seal between the
ear-muffs and head. Interference with the seal between the ear-muffs and head can reduce the noise
attenuation of the ear-muffs. Failure to obey this warning can result in permanent hearing loss.
See Figure 2.
Make sure that you adjust the chin strap for a tight fit. To apply equal pressure between all four
Y straps, pull the webbing through the side adjusters until the lengths are correct.
