Standard Development
• Existing NIOSH or military standards are not completely applicable to meet a terrorism agent threat • Inherent differences between NIOSH and military standards
− Purpose − Target user groups − Hazards − Operation − Protection
NPPTL Year Month Day File name
CBRN Standard Development Process
• Hazard analysis • Protection • Human factors and environmental factors • Standards concept definition • Test requirements and research • Testing and validation • Quality assurance requirements • Public process

CBRN Standards Partnerships
• Workshops/Committee Meetings
− NIOSH-DOD-OSHA Chemical-Biological Respiratory Workshop & Report (March 1999) − Interagency Board standards & PPE committees
• Cooperation among NIST, RDECOM, OSHA, NIOSH,NFPA, and DHS • Define collaboration for CBRN standards development • IAA’s with NIST and RDECOM • Initial and continuing funding from NIST-NIJ/NISTDHS/CDC • RDECOM technical support for testing
NPPTL Year Month Day File name
CBRN Standard Development
• The partnerships established as part of the standards development program have enabled NIOSH to gain nationally based support of the standards. • The CBRN respirator standards have been endorsed and incorporated by other standard generating organizations (DHS, NFPA).

CBRN Standards Development Hazards Assessment
• Chemical warfare agents (CWA) and toxic industrial chemicals (TIC) represented the most critical challenges and would serve well as surrogate test agents for the biological, radiological, and nuclear particulate hazards.
NPPTL Year Month Day File name
CBRN Standards Development Process
• Two primary considerations were identified for certification criteria for equipment used by first responders to CBRN incidents
− A hazard assessment of possible CWA incidents − An analysis of human factors requirements
NPPTL Year Month Day File name
CBRN Standards Development Process
• The hazards assessment developed in support of the standards development effort addressed multiple, plausible, chemical terrorist scenarios • The report focused on indoor events because the first responders to an indoor chemical terrorist incident are expected to experience higher vapor concentration levels than an outdoor incident due to building confines, and atmospheric conditions not present to disperse the agent
NPPTL Year Month Day File name
CBRN Standards Development Process
• The intent of developing these scenarios was to identify reasonable, probable, and critical concentrations, a “most credible event”, that could be expected in the deployment of CWA.
NPPTL Year Month Day File name
CBRN Standards Development Process
• The test challenge concentrations selected are not maximum values; these vapor concentrations are considered the most likely to occur and been seen by a responder in the early stages of an incident response.

CBRN SCBA Standard
• Chemical, Biological, Radiological and Nuclear (CBRN) Standard for Open-Circuit Self-Contained Breathing Apparatus, December 28, 2001 • Three tiers of technical requirements
− 42 CFR NIOSH approval − National Fire Protection Agency (NFPA) 1981 − Special CBRN tests:
• Laboratory protection level • Chemical warfare agent tests (GB & HD)

CBRN APR Standard
• CBRN APR – March 2003 • Public process • Work with U.S. Army RDECOM to:
− Define respirator requirements − Develop test procedures − Perform tests
• Major responder needs:
− − − − Multi-hazard protection Chemical warfare agent testing Enable Interoperable filters and masks High demand (physiological)
• Approvals: 2 APR manufacturers

CBRN Escape Set Standard
• Threat analysis, site specific • Escape strategy: − Exit immediately − Progress to designated area − Shelter in-place • 3 protection levels for escape respirators: − General (APR) − Specific (APR) − High (SAR) • Statement of Standard for Chemical, Biological, Radiological and Nuclear (CBRN) Air-Purifying Escape Respirator and Statement of Standard for Chemical, Biological, Radiological and Nuclear (CBRN) SelfContained Escape Respirator, September 30, 2003

Goal:
• Develop a NIOSH/NPPTL tight fitting, powered air purifying respirator standard for emergency responders that address CBRN materials identified as inhalation hazards and/or possible hazards from terrorist activity.
