The U. S. Department of Agriculture, Forest Service, National Technology and Development Program (NTDP), is evaluating wildland firefighter helmets.
The current Interagency Standards for Fire and Fire Aviation Operations (Redbook) require all wildland firefighters to wear helmets at all times while in the fire area. 
Forest Service personnel must use helmets that meet the National Fire Protection Association (NFPA) 1977 Standard on Protective Clothing and Equipment for Wildland Fire Fighting requirements. U.S. Department of Interior, Bureau of Land Management (BLM) personnel must use helmets that meet industrial head protection criteria of the American National Standards Institute (ANSI) Z89.1, Type 1, Class G, or NFPA-1977.
A Type 1 helmet is intended to reduce the force of impact resulting from a blow to the top of the head. A Class G helmet is intended to reduce the danger of contact with low voltage (2,200 volts/2.2 kilovolts) electrical conductors.
Your responses to the questionnaire will help NTDP determine if the current helmet design and requirements meet the needs of the wildland firefighter. Your feedback will assist in the development of possible improvements. 
Thank you for taking the time to participate in this evaluation. Your valuable feedback helps improve the safety, quality, and function of wildland firefighting equipment.
Please respond to this evaluation by September 30, 2018.
