Warnings, Regulations and Standards
for Head Protection

OSHA 29 CFR 1910.135 - www.osha.gov
This standard requires head protection if any aspect of the work environment presents a risk of head injury.

ANSI Z89.1-2003 - www.ansi.org
National Standard for U.S.
This standard developed requirements for industrial head protection relating to:

  1. Impact Protection;
  2. Penetration Protection; and
  3. Electrical Insulation Protection.
“This fifth revision of the standard provides performance and testing requirements for industrial helmets, commonly known as hard hats, and is a revision of ANSI Z89.1-1997, which established the types and classes of protective helmets, depending on the type of hazard encountered. The 1997 version included specifications for helmets designed to offer protection from lateral impact, or top-only impact, giving employers and users the flexibility to specify the helmet that best meets the needs of their specific workplace. Industrial head protective helmets meeting the requirements of the 2003 standard are classified as Type I for top protection or Type II for top and lateral impact protection. Both types are tested for impact attenuation and penetration resistance. Type II helmet performance requirements include criteria for impact energy attenuation from impacts from the front, back and sides, as well as the top, off-center penetration resistance and chin strap retention. The three classes indicate the helmet’s electrical insulation rating, and is unchanged from 1997.”

CAN/CSA Z94.1-2005 - www.csa.ca
National Standard for Canada
This is the fifth edition of CSA Z94.1, Industrial Protective Headwear - Performance, selection, care and use. It supersedes the previous editions published in 1992, 1977 and 1966 under the title Industrial Protective Headwear. It also supersedes the Preliminary Standard, published in 1965, and replaces the protective headwear requirements specified in CSA Z94-1948, Code for Head and Eye Protection.

Types of Hard Hats

Type I - Conventional hard hats that are designed to reduce the force of impact to the top of the head, neck and spine. Type II - New designs that offer additional impact protection to the front, sides and back, as well as the top of the head.


Classes of Hard Hats
Class E (electrical) - Tested to withstand 20,000 volts. Class G (general) - Tested to withstand 2200 volts. Class C (conductive) - Provides no electrical protection.
