MAINTENANCE HAZARDOUS WASTE MANUAL <br /> Chapter 2 <br /> Page 14 <br /> SIGNAGE <br /> NFPA 704 Warning System <br /> Background The Standard System for the identification of the fire hazards <br /> of materials was first adopted by the NFPA in 1961. The <br /> purpose of the standard is to safeguard the lives of those <br /> individuals who may be concerned with fires or emergencies <br /> occurring in an industrial plant or storage location where the <br /> hazards of materials on-site may not be readily apparent. <br /> Applicability Applies to facilities that manufacture, store or use hazardous <br /> materials. <br /> Purpose Provides a simple system of readily recognizable and easily <br /> understood markings which will give, at a glance, the general <br /> idea of the inherent hazards of any hazardous material. <br /> Components Identifies the hazards of a material in terms of three principle <br /> categories: Health, Flammability and Reactivity. <br /> Indicates order of severity numerically by five divisions <br /> ranging from four(4), indicating a severe hazard, to zero (0), <br /> indicating no special hazard. <br /> The diamond shapes present information by a standard pattern <br /> of shapes and colors; Health(blue), left; Flammability(red), <br /> top; Reactivity(yellow), right. <br /> The bottom space indicates unusual hazards such as reactivity <br /> with water, oxidizing properties or radioactivity. <br /> July 2018 <br />
