NFPA 704 处置突发事故时材料危险性鉴别方法
 
1.1 Scope. This standard shall address the health, flammability, instability, and related hazards that are presented by short-term, acute exposure to a material under conditions of fire, spill, or similar emergencies.
 
Make sure critical hazard ratings are accurate and easily understood with NFPA 704.
Displayed in markings commonly referred to as the "NFPA? hazard diamond," NFPA 704 ratings are based on NFPA 704 Standard System for the Identification of the Hazards of Materials for Emergency Response, the system that simplifies determining the degree of health, flammability, and instability hazards of chemicals. NFPA 704 also provides for the recognition of water reactivity and oxidizers.
This 2012 edition helps users work more accurately with
·    New guidance on the flammability hazard classification for aerosol products in Table 6.2.
·    New text in Table 6.2 emphasizing the use of Annex D to classify the flammability hazard of a finely-divided solid
·    Differential scanning calorimetry (DSC) hazard criteria reinstated to Table 7.2.
Changes make this edition of NFPA 704 essential for manufacturers and users of hazardous chemicals, emergency responders to such facilities, and consultants specializing in hazard identification and mitigation. (Softbound, 21, pp., 2012)
