  • Type Protective Helmetwarnings, cautions, and instructions

    HELMET DESCRIPTIONThis helmet meets the requirements of the ANSI Z 89.1, 1997 Stan-dard for protective headwear for industrial workers. The ANSI electri-cal insulation classification listed below is indicated on the label in-side the helmet.

    Class G (formerly Class A) - Tested to 2,200 voltsClass E (formerly Class B) - Tested to 20,000 voltsClass C - Not tested

    This helmet is certified by the Safety Equipment Institute (SEI).

    This helmet is a system consisting of a shell and suspension whichwork together as a unit. An optional chinstrap is available that workswith the suspension to provide additional helmet retention. Since it isa system, each part must be kept in good condition to provide protec-tion. This helmet is designed to provide LIMITED impact and penetra-tion protection to the wearers head in the event of a blow to the top ofthe head. Class G and E helmets are also designed to provide LIM-ITED electrical insulation protection. This helmet has been shippedwith suspension disengaged from shell to prevent distortion duringshipping. Install suspension as follows:

    1. Set the helmet on its top.2. Line up the suspension so that the sweatband is on the side of the

    cap with the letters MSA stamped on the brim.3. Fold the clips up and out (Fig. 1) slotted; (Fig. 2) riveted.

    4. Line up the clips with the slots. Push each of the four clips into itsslot (Fig.3). You should feel and hear them snap into place.

    If, after reading these instructions, there is ANY doubt as to the degreeof protection offered by this helmet, or if there is confusion concerningspecific conditions which may limit the helmets protective capabili-ties, immediately contact your supervisor or safety director. Save thisbag for future reference. If you have any questions or require addi-tional information, please call: 1-800-MSA-2222, or write: MSA, P.O.Box 426, Pittsburgh, PA 15230.

    WARNINGFAILURE TO FOLLOW THE WARNINGS LISTED BELOW CANRESULT IN SERIOUS PERSONAL INJURY OR DEATH.

    This Type helmet provides LIMITED impact and penetra-tion protection to the top of the head.

    MSA Type helmets are not specifically designed to pro-tect against lateral blows from the front, side, or rear. MSAslateral protective helmets are so designed and MUST beused if lateral protection is desired. For more information,contact MSA. This helmet meets or exceeds the appli-cable requirements for a Type helmet (top impact) asoutlined in ANSI Z89.1 1997 and in most circumstancesshould be effective against small tools, bolts, rivets,sparks, and similar hazards; however, some conditions canexceed this helmets capacity to protect against seriousinjury or death. AVOID areas where the chance of severehelmet impact or penetration exist .

    Class G (formerly Class A) and E (formerly Class B) hel-mets provide LIMITED electrical protection as outlined inthe ANSI Z89.1, 1997 Standard. Sample helmets are prooftested to 2,200 volts (RMS) for Class G and 20,000 volts(RMS) for Class E, but these should NOT be construed assafe contact voltages.

    In order to provide maximum protection, the helmet MUSTfit securely on the head and the headband MUST be ad-justed to a snug fit. Always wear helmet so that nape strap(suspensions adjustment) is at rear of head; otherwise,reduced protection MAY result particularly if the helmet isworn tilted back. If you prefer to wear the helmet with thebrim backwards, reverse the suspension so that the napestrap remains at the rear of the head. Although properlyadjusted, some conditions such as high wind or helmetimpact can dislodge the helmet from the head. To provideLIMITED additional retention capability, wear a chinstrap.

    Although it may provide limited head protection in the eventof a fall, this helmet IS NOT designed for fall protection.

    NEVER use this helmet as a vehicular or sports helmet.

    NEVER store gloves, cigarettes, earplugs, etc. between thesuspension and the shell. This space is needed when theshell suspension absorbs the energy of an impact. Ob-jects in this space can transmit large forces to the headand neck, resulting in serious injury or death.

    Inspect the helmet before and after EACH use. ALWAYSfollow the inspection procedure on this bag. Replace ANYpart showing wear or damage.

    NEVER exceed useful service life guidelines of helmet asoutlined on this bag. Replace components or helmet asrequired.

    NEVER alter or modify this helmet in ANY way. Use ONLYMSA supplied or approved accessories with the helmet. Itis permissible to use pressure sensitive identification de-cals or Velcro on the helmet as long as they ARE NOTcloser than 1/2 inch from the edge of the helmet. Modifica-tions, or use of other than MSA accessories, can reducethe protection levels or dielectric properties (if applicable)designed into the helmet.

    NEVER use paint, solvents, or hydrocarbon type cleaners(e.g. M.E.K., thinner, gasoline, kerosene) on this helmet.These substances can damage the helmet materials in amanner which MAY NOT be visible to the user, causingthe helmet to fail. Certain paints contain solvents whichcan damage parts of the helmet assembly.

    CAUTION

    This helmet MUST be stored in a clean, dry area where it isnot exposed to extremes of heat or cold which can affectthe helmets useful service life.

    Clean with a mild soap and warm water to help avoid skinirritation from wearing the helmet.

    Even though sample helmets are proof tested to 2,200 V.for Class G and 20,000 V. for Class E, the maximum volt-age against which the helmet will protect the wearer de-pends upon a number of variable factors, such as the char-acteristics of the electrical circuit, the care exercised in themaintenance of the helmet and weather conditions. Thesafe and proper use of the helmet in electrical applicationsshould be established by the authority having jurisdictionand their recommendations MUST be strictly followed.

    5. Line up the clips with the studs. One at a time, slide the twoprongs on the clip under the stud (Fig. 4A). Grasp webbingfirmly approximately 2" below the metal clip and pull in a down-ward direction until you hear or feel the clip snap into place(Fig. 4B) .

    CAUTION Do not pull on the headband during installation. Pull on

    the webbing only, otherwise damage may occur to thesuspension.

    WARNING

    Do not mix suspension and helmet sizes. Make sure thesizes match (example: medium size suspension with me-dium size helmet).

    Use only MSA suspensions on an MSA helmet.

    Failure to comply with the above will reduce the energyabsorbing ability of the protective helmet which can resultin serious personal injury or death.

What is the difference between Type I and Type II hard hats? ›

Type I hard hats are only designed to protect workers from objects and blows that come from above and strike the top of a helmet. Type II hard hats are designed to offer protection from lateral blows and objects. This includes from the front, back, and side as well as from the top.

What are the three types of hard hats? ›

Types of Hard Hats

The three classes are based on the level of protection they provide from electrical hazards. Class G (General) hard hats are rated for 2,200 volts. Class E (Electrical) hard hats are rated for 20,000 volts. Class C (Conductive) hard hats do not offer electrical protection.
