 | | The 704 rating system is applicable to industrial, commercial, and institutional facilities that manufacture, process, use, or store hazardous materials. |
 | | This is a relevant matter, because the NFPA 704 system is often confused with the placarding required by the Department of Transportation for hazardous materials. |
 | | Of course, as stated in NFPA 704, Standard System for the Identification of the Hazards of Materials for Emergency Response, Section 4.2.3.1, professional judgment must still be used to increase or decrease the rating to more accurately assess the degree of hazard, perhaps due to quantities, or synergistic effects of the chemicals, etc. |
