NFPA 1992 — Standards for Non-Carcinogenic Vapors

NFPA 1992 provides standards for emergency response PPE against liquid splash, particulate materials, and non-carcinogenic vapors in HAZMAT environments.

NFPA 1992 Overview

NFPA 1992, Standard on Liquid-Splash Protective Ensembles and Clothing for Hazardous Materials Emergencies, 2005 Edition, addresses liquid-splash protection during HAZMAT incidents. NFPA allows ensembles (completely covering the body) or clothing (protects the torso, arms, and legs and optionally the arms, feet, and head). Both NFPA 1991 and NFPA 1992 standards can be used to certify for protection against additional chemicals and mixtures, but NFPA 1992 is limited to chemicals that have a vapor pressure greater than 5 mm Hg at 25°C (77°F), are not of known or suspected human carcinogenicity as indicated by either the Dangerous Properties of Industrial Chemicals document or the NIOSH Pocket Guide to Chemical Hazards documents, and do not have a skin notation as indicated by the American Conference of Governmental Industrial Hygienists’ Threshold Limit Values for Chemical Substances and Physical Agents and Biological Exposure Indices.

NFPA 1992 Testing Requirement Details

Specific testing required by NFPA 1992 includes:

  • "Shower" testing to demonstrate liquid-tight integrity
  • Penetration testing against five liquid industrial chemicals
  • Burst strength, puncture resistance, cold temperature performance, abrasion resistance, and flex-fatigue testing of suit, glove and footwear materials
  • Breaking-strength testing for seams and closures

NFPA 1992 provides for an optional flash fire endorsement. For this endorsement, the garment must maintain liquid protection and exhibit a high level of resistance to surface flame impingement.
