CLASS A FOAMS - SPECIFICATION CHANGE NOTICE

The USDA Forest Service (USFS) has an on-going need for adequate types and quantities of Class A Foams for wildland fire management to accomplish fire management activities safely, efficiently, and effectively (Forest Service Handbook 5109.16). To accomplish this, the USFS has an established testing and approval procedure to evaluate products that suppliers propose for use by the USFS and its Federal cooperators during wildland fire management operations. The Forest Service regularly reviews and updates this specification. All products submitted under the established Qualification Requirement (QR) must meet USFS specifications. The current specification, 5100-307a, has been revised. The revised specification, 5100-307b, will be effective 15 days after this posting (April 1, 2021). All new and current submissions will be evaluated and qualified according to the revised specification. Any Class A Foam currently on the Qualified Products List (QPL) will be reexamined based on the revised specification. Products not meeting the requirements of 5100-307b will be removed from the QPL by December 31, 2022. The current specification for water enhancers, 5100-307a, can be found on the Wildland Fire Chemical Systems website at https://www.fs.fed.us/rm/fire/wfcs/ The revised specification for water enhancers, 5100-307b, can be found on the Wildland Fire Chemical Systems website at https://www.fs.fed.us/rm/fire/wfcs/ Questions may be sent by email or hard copy through the Post Office to: Shirley Zylstra Program Leader – Fire Chemicals USDA Forest Service - National Technology & Development Program 5785 Highway 10 West; Missoula, MT 59808 [email protected] or Dave Haston Branch Chief - Fire Equipment and Chemicals USDA Forest Service, Fire and Aviation Management National Interagency Fire Center 3833 S.
