Title: Garment, Vapor-Protective, NFPA 1991


Last Updated: 7/8/2022 1:56:49 PM

Previous SEL Number: 01VT-02-GARM

Description: Vapor-protective garment (certified as compliant with the NFPA 1991 requirements of NFPA 1990).

ImportantFeatures: NFPA 1991 defines an ensemble consisting of a suit with attached gloves that totally encapsulates the wearer and his or her breathing apparatus. Ensembles are frequently configured with an overcover, outer gloves, and outer boots in order to meet the requirements of the standard; however, some products can meet the requirements without these extra layers. Suit materials, including visors and seams, are evaluated for permeation resistance against 24 different industrial chemicals and 2 chemical warfare agents. NFPA 1991 also includes optional criteria for liquefied gas protection and flash fire escape protection. Additional criteria are provided for each of the certification options. Product labels must clearly indicate which options apply to the specific ensemble. The primary purpose of NFPA 1991 is to define requirements that isolate the wearer from a surrounding hazardous chemical environment.

Operating Considerations: NFPA 1991 defines the highest level of protection for hazardous material emergencies. NFPA 1991 ensembles are intended for severe chemical exposure skin hazards. The suits are designed to provide protection from gases, vapors, liquids, and particulates. Level A ensembles should not be used without extensive training. Use considerations are provided in OSHA Title 29 CFR Sections 1910.120 and 1910.132, and NFPA 1500, Standard on Fire Department Occupational Safety and Health Program.
