NFPA 704 Marking System

Which of the following is not one of the four colors of the NFPA 704 marking system ... 

The National Fire Protection Association (NFPA) has developed a fixed-facility marking system to designate general hazards of chemicals (see Figure 1.9), referred... 

Ha2ard identification of the contents of in-plant bulk storage tanks, warehouses, etc, may be achieved by a system developed by the NFPA (48). The system makes use of three diamond-shaped areas, which are marked with numbers 0, 1, 2, 3, or 4 indicating increasing ha2ards of toxicity, flammabHity, and reactivity, respectively. 

This is a brief summary of NFPA 704 which addresses hazards that maybe caused by shoii-term, acute exposure to a material during handling under conditions of fire, spill, or similar emergencies. This standard provides a simple, easily recognized, easily understood system of markings. The objective is to provide on-the-spot identification of hazardous materials. 

These markings provide a general idea of the hazards of a material and the severity of these hazards as they relate to handling, fire protection, exposure, and control. This standard is not applicable to transportation or to use by the general public. It is also not applicable to chronic exposure. For a full description of this standard, refer to NFPA 704. The system identifies the hazards of a material in four principal categories health, flammability, reactivity, and unusual hazards such as reactivity with water. 

Beyond perfonnance optimization, issues relative to packaging and the need for compliance with certain safety and electronics regulatory codes are cited as reasons for a customized solution. In the latter case, a systems approach is required, especially when attempting to meet the code or performance requirements for compliance with European Certification (CE) mark or electrical and fire safety codes such as National Eire Prevention Association (NFPA) and CENELEC (European Committee for Electrotechiucal Standardization). Off-the-shelf electronics may provide the necessary performance characteristics for generic applications, and their use eliminates large expenses related to product development, plus the associated time delays. Photonics-related components are solely addressed in this section because they are used to customize instruments for application-specific systems. 

NFPA 704 is a system of marking storage containers to communicate the hazards associated with the contents of the container. It utilizes a diamond-shaped symbol broken into four quadrants at the top.
