What is the new 1990 consolidated standard?

The 1990 standard consolidated the three hazmat standards currently approved and issued by the NFPA. These are 1991, 1992 and 1994. The scopes of the three standards have been combined and a reference to the new NFPA 1891, Standard on Selection, Care and Maintenance of Hazardous Materials Clothing and Equipment, which was developed in parallel, has been added.

The new standard addresses these areas:

  • Different footwear design and performance criteria are separated to address separate requirements for ensemble socks, full boots and outer boots.
  • A new test for flame break open resistance has been put together based on a government-sponsored study demonstrating the need to address materials that can potentially be compromised by prolonged exposure to flame and radiant heat sources.
  • The optional overall ensemble flash fire test has been updated to a more consistent test platform based on an ASTM test method with changes to the criteria reflecting first responder protection needs. An additional optional test has been added to measure percent body burn if chosen by the manufacturer.
  • NFPA 1994 Class 5 ensembles have been added to provide protection for non-skin toxic chemical threats with flammability hazards building on NFPA 1951, Standard on Protective Ensembles for Technical Rescue Incidents, for its base requirements to allow for ease of dual certification.
  • All test methods have been combined into one chapter and modified to address each of the individual standards as needed.
  • A new low vapor agent permeation test has been added to address the evaluation of sulfuric acid against Class 1 materials. Liquid chemical runoff testing has been established based on an ISO test method for evaluation of Class 5 materials.
  • Updated, consolidated annex information is included that shows the relationship of the different ensemble types and classes to OSHA 1910.120, Hazardous Waste Operations and Emergency Response.

Why do we need it?

An updated and uniform set of definitions has been added to provide consistency in terminology throughout the consolidated standard. Specific efforts have been made to streamline certification, labeling, design and performance requirements using a table format to allow for comparisons and efficient referencing relative to each type and class of ensemble.
