05.D Head Protection.
05.D.01
All persons working in or visiting hard hat areas must be provided with and required to wear Type I or Type II, Class G (General - not to exceed 2,200 volts) or Class E (Electrical-not to exceed 20,000 volts) headgear as appropriate.
The selection of the type of hardhat must be based on the activity and identified in the AHA. For emergency response operations and other activities with greater need for side impact protection, Type II head protection is required. > See Appendix B. For more information on hardhats, see Creative Safety Supply .
- Hard hat areas or activities are those areas with potential hazard of head injury; in general, all construction areas are considered hard hat areas. However, specific areas may be designated as non-hard hat areas, or activities may be considered non-hard hat activities, if identified and properly documented in the associated AHA. The identification and analysis of head hazards will be documented in an AHA or project safety and health plan, as appropriate.
- Points of entry to a hard hat area must have a sign warning of the requirement to wear hard hats.
05.D.02
All protective headgear must meet the requirements of ANSI Z89.1.
- No modification (i.e., paint) to the shell or suspension is allowed except when such changes are applied or approved by the manufacturer. Stickers are allowed on the hard hat provided they do not interfere with the ability to properly inspect it. > See 05.D.03.
- Hard hats must be worn with the bill facing forward unless the GDA has determined exceptions for certain trades in order to accommodate appropriate mission accomplishments. Headgear must be designed to accommodate these needs.
- Protective headgear worn near electric lines and equipment must be Class E.
- No ball caps, knit caps, or other headdress must be worn under the hard hat that could interfere with the fit or stability of the hard hat.
05.D.03
Protective headgear and components must be visually inspected daily for signs of damage (dents, cracks, etc.) that might reduce the degree of safety integrity originally provided. Headgear will be periodically inspected for ultraviolet degradation as evidenced by cracking or flaking of the helmet.
05.D.04
Drilling holes or in any way changing the integrity of the hard hat is prohibited. Alterations that will reduce the dielectric or impact strength will not be made.
05.D.05
Protective headgear worn by USACE employees must (in addition to complying with the preceding specifications) be:
- White in color and marked with a 1 in (2.5 cm) band of red reflective material placed along the base of the crown with a 5 in (12.7 cm) break in front. A red Corps of Engineers castle insignia will be centered at the front of the hat with the base of the insignia approximately 3/4 in (1.9 cm) above the base of the crown. Personnel may place their name above the insignia and their organization title below the insignia: the rank of military personnel should precede their name. An American Flag insignia may be worn on the back of the hard hat.
- Requests for variations in color and marking to accommodate occupational specialties must be submitted for consideration to HQUSACE Safety and Health Office.
- Chin straps will be worn when wearers are subject to high wind conditions and/or working on elevated structures.
