Use
The helmet is made for intended use only.
-
Helmets absorb the energy of a blow by partial destruction of, or damage to, the helmet.
-
Even though such damage may not be readily apparent, any helmet subjected to a severe
impact should be replaced.
Do not modify or remove any of the original component parts of the product, if not
-
recommended by MSA.
Do not apply paint, stickers, cleaning products with a hydrocarbon base or solvents to the
-
helmet or visors to prevent damaging the materials.
Avoid areas where the chance of severe helmet impact or penetration exists.
-
Avoid areas where the chance of severe electrical shock exists.
-
Never use this helmet as a vehicular or sports helmet.
-
Never store gloves, cigarettes, earplugs or similar objects between the suspension and the
-
shell liner. This space is needed when the shell/ suspension absorbs the energy of an impact.
Use only MSA supplied or approved accessories with this helmet.
-
The helmet must not be thrown, dropped or used as a support.
-
No harmful material was used. In case of allergic reaction, exit the danger zone and remove
-
the PPE.
Face shields worn over non-designated corrective frames may transmit impacts which may
-
damage the corrective eye wear thus creating a hazard to the user.
Service life of face shields depends on the conditions of use.
-
Check face shield marking to ensure that the visor is sufficient for the intended activity.
-
The face shield only performs as expected in use position (low position).
-
Any face shield that has been scratched, dropped or damaged must be replaced.

The face shieds are designed exclusively for assembly on MSA V-Gard 900 helmet type.
-
The face shields could be damaged by some chemicals substances.
-
The Arc Flash Ear-flaps must not be worn in the up position if there is any risk of molten
-
metal splashes.
If protection against high speed particles at extremes of temperature is required, then the
-
selected eye protector should be marked with the letter T immediately after the impact letter
(BT). If the impact letter is not followed by the letter T then the eye protector shall only be
used against high speed particles at room temperature.
While the helmet and the accessories can be used at temperatures up to -30 °C, do not
-
adjust arc flash ear-flaps in temperatures of -10 °C and below.
Protection can be reduced because of aging or inappropriate cleaning method, insulating is
-
limited depending on conditions of use.
