INDUSTRIAL PROTECTIVE HELMETS
1. SCOPE: This specification establishes requirements for safety helmets for the protection of heads of occupational workers from impact and penetration from falling and flying objects and from high-voltage electric shock and burn. The impact and penetration resistance, and the electrical insulation requirements of the user are beyond the scope of this specification and therefore the requisites outlined herein should not be construed to indicate the safe impact, penetration level, or safe voltage to which the helmet wearer may be subjected.

11. COMPLIANCE: In order for consideration to be given to the bid on an item under this specification, the bidder must comply with the following:
11.1. PRODUCT IDENTIFICATION: The make, model number, name of the manufacturer, brand or trade name, etc., as applicable, of the item which the vendor proposes to furnish must be stated as part of the bid.
11.2. EXCEPTIONS: Notwithstanding the above, any exception taken by the bidder to the requirements and conditions of this specification must be stated and described in detail as a part of the bid. If no exceptions or deviations are identified in this manner, the items must be furnished exactly as described herein.
11.3. PROOF: The bidder shall bear the burden of proof of compliance with this specification.
12. PRODUCT INFORMATION: The following information is furnished primarily as recommendations concerning the use of protective helmets.
12.1. LACES: Laces, if any, should always be tied securely with a square knot.
12.2. PAINTING AND CLEANING: Caution should be exercised if shells are to be painted since some paints and thinners may attack and damage the shell and reduce protection. The manufacturer should be consulted with regard to paints or cleaning materials for their particular products. A common method of cleaning and sterilization of shells is dipping them in hot water (approximately 140 ° F) containing a good detergent for at least a minute. Shells should then be scrubbed and rinsed in clear water (approximately 140 ° F). After rinsing, the shell should be carefully inspected for any signs of damage.
12.3. PERIODIC INSPECTION: All components, shells, suspensions, headbands, sweatbands, and any accessories should be visually inspected daily for signs of dents, cracks, penetration, or any other damage due to impact, rough treatment, or wear that might reduce the degree of safety originally provided. Any industrial protective helmet that requires replacement or the replacement of any worn, damaged, or defective part should be removed from service until the condition of wear or damage is corrected.
12.4. LIMITATION OF PROTECTION: Industrial protective helmets meeting ANSI standards and the requirements of this specification are designed to provide optimum protection under average conditions. Users are cautioned that if unusual conditions prevail (such as higher or lower extremes of temperature than described or other unusual conditions) or if there are signs of abuse or mutilation of the helmet or any component, the margin of safety may be reduced.
12.5.1. All items constructed of polymeric materials are susceptible to damage from ultraviolet light and chemical degradation, and safety helmets are no exception. Periodic examinations should be made of all safety helmets and in particular those worn or stored in areas exposed to sunlight for long periods. Ultraviolet degradation will first manifest itself in a loss of surface gloss called chalking. Upon further degradation the surface will craze or flake away or both. At the first appearance of either or both of the later two phenomena the shell should be replaced immediately for maximum safety.
12.5.2. The addition of accessories to the helmet may adversely affect the original degree of protection.
12.5.3. Because helmets can be damaged they should not be abused. They should be kept free from abrasions, scrapes, and nicks and should not be dropped, thrown, or used as supports. This applies to all helmets, but especially to helmets intended to afford protection against electrical hazards.
13. ORDERING DATA: When ordering products conforming to this specification the requisitioning agency shall specify the following:
13.1. The number of this specification (345-56-01C).
