Title: Ensemble, HazMat Emergency and Terrorism Incident Protective, NFPA 1994 Class 1


Last Updated: 4/3/2024 5:01:55 PM

Previous SEL Number: 01CB-01-ENSM

Description: NFPA
National Fire Protection Association
1994 Class 1 HazMat Emergency and CBRN
Chemical, Biological, Radiological, Nuclear
Terrorism Incident Protective Ensemble, including garment, gloves, footwear, and CBRN
Chemical, Biological, Radiological, Nuclear
SCBA
Self Contained Breathing Apparatus
(certified as compliant with the NFPA
National Fire Protection Association
1994 Class 1 requirements of NFPA
National Fire Protection Association
1990). NFPA
National Fire Protection Association
1994 Class 1 certifications specify these elements by make/model -- using any element other than those specified invalidates the certification. The elements of this Item should be purchased and used as a complete ensemble.

ImportantFeatures: Ensembles certified as compliant with NFPA
National Fire Protection Association
1994 Class 1 requirements consist of a full body or multi-piece garments, gloves, footwear, and CBRN
Chemical, Biological, Radiological, Nuclear
Self-Contained Breathing Apparatus (SCBA
Self Contained Breathing Apparatus
). Note that the certification applies to a specific set of elements identified by make/model (garment, gloves, boots, SCBA
Self Contained Breathing Apparatus
) and the ensemble certification is void unless the specified elements are used (e.g., it is not permissible to use a respirator that has not been certified as part of the ensemble). Footwear certified to certain other standards (e.g., NFPA
National Fire Protection Association
1950, NFPA
National Fire Protection Association
1970) is acceptable if the footwear height is at least 8 inches when measured from the floor.

The ensemble may be designed with the SCBA
Self Contained Breathing Apparatus
worn inside or outside the ensemble. The ensemble is designed to minimize the inward leakage of gases or vapors as demonstrated by a man-in-simulant test where performance levels have been set at levels commensurate with protection in an IDLH (Immediately Dangerous to Life or Health) environment. Ensembles are further evaluated for integrity with respect to liquid penetration. Materials are tested for permeation resistance to selected chemical agents and toxic industrial chemicals at concentrations consistent with the same levels used for evaluating CBRN
Chemical, Biological, Radiological, Nuclear
SCBA
Self Contained Breathing Apparatus
; materials must also provide minimal levels of flame resistance, and various physical properties to demonstrate adequate physical hazard resistance and durability for a single use. Ensembles are also tested for functionality.

Operating Considerations: Class 1 ensembles are designed to protect emergency first responder personnel during hazardous materials emergencies and at terrorism incidents involving vapor or liquid chemical hazards where the concentrations are at or above Immediately Dangerous to Life or Health (IDLH) levels, requiring the use of SCBA
Self Contained Breathing Apparatus
.

Conditions of exposure include possible contact with vapors, gases, liquids, aerosols, particulates and highly contaminated surfaces at the emergency scene where skin contact is expected to be at moderate levels. The condition of victims may vary. Most victims in the response area would likely be alive and show signs of movement, but non-ambulatory. For Class 1 ensembles, breathing air from the SCBA
Self Contained Breathing Apparatus
may limit wearing time. Use considerations are provided in OSHA Title 29 CFR
Code of Federal Regulations
Sections 1910.120 and 1910.132, and NFPA
National Fire Protection Association
1500, Standard on Fire Department Occupational Safety and Health Program.

Training Requirements: Core Training: NFPA
National Fire Protection Association
470 Chapters 6, 8, 10 as applicable, OSHA 1910.120, OSHA 1910.132.
Initial Training: Moderate (1-2 days)
Sustainment Training: Minimal (<1 day)
