NFPA 1991 Standard on Vapor-Protective Ensembles for Hazardous Materials Emergencies
NFPA 1991 處置化學危險品事故用防毒氣服裝標準
1-1.1* This standard shall specify minimum design, performance, certification, and documentation requirements; and test methods for vapor-protective ensembles and individual elements for chemical vapor protection; and additional optional criteria for chemical flash fire escape protection and liquefied gas protection.
1-1.2* This standard shall also specify additional optional criteria for vapor-protective ensembles and individual elements that will provide protection from chemical and biological warfare agents and chemical and biological terrorism incidents.
1-1.3 This standard shall apply to the design, manufacturing, and certification of new vapor-protective ensembles and new individual elements. This edition of this standard shall not apply to vapor-protective ensembles and individual elements manufactured to previous editions of NFPA 1991, Standard on Vapor-Protective Suits for Hazardous Chemical Emergencies.
1-1.4* This standard shall not apply to protective clothing for any fire fighting applications and shall not provide criteria for protection from radiological or cryogenic liquid hazards, or from explosive atmospheres. This standard shall not apply to vapor-protective ensembles for protection from biological hazards unless the ensemble is certified as compliant with the additional requirements for chemical and biological terrorism incidents.
1-1.5 This standard shall not specify the respiratory protection that is necessary for proper protection with the protective ensemble.
1-1.6 This standard shall not apply to use requirements for vapor-protective ensembles or individual elements as these requirements are specified in NFPA 1500, Standard on Fire Department Occupational Safety and Health Program.
1-1.7 Certification of compliant vapor-protective ensembles and compliant individual elements to the requirements of this standard shall not preclude certification to additional appropriate standards where the ensemble or individual elements meet all the applicable requirements of each standard.
1-1.8 The requirements of this standard shall not apply to accessories that might be attached to a vapor-protective ensemble, to an ensemble element, or to an individual element unless specifically addressed herein.
1-1.9 Nothing herein shall restrict any jurisdiction or manufacturer from exceeding these minimum requirements.
Equip responders to guard against haz-mat dangers.
The 2005 NFPA 1991 provides requirements for the highest level of protection for emergency responders to hazardous materials incidents where an unknown threat, a vapor threat, or a chemical or biological terrorism WMD threat is present or expected. Criteria address design, performance, certification, and documentation requirements.
This latest Standard edition contains the following changes that optimize protection for emergency responder personnel
· Former optional requirements for chemical and biological agent threats are now mandatory for all vapor-protective ensembles compliant with NFPA 1991.
· Optional requirements for limited protection for escape only in the event of chemical flash fire, and optional requirements for protection from liquefied gas are provided.
· Test methods have been refined to improve clarity, consistency, and repeatability.
· Text refinement provides clearer criteria.
NFPA 1991 has been adopted by the U.S. Department of Homeland Security (DHS).
