Where should NFPA 704 signs be affixed?

NFPA 704 signs, also known as fire diamond signs, play a crucial role in indicating the hazards associated with materials present at a location. The primary purpose of these signs is to provide first responders with essential information concerning the potential dangers posed by hazardous materials at a site.

By affixing NFPA 704 signs on aboveground tanks and entrances to locations dealing with hazardous materials, the signs effectively alert responders to the nature and level of hazards they may encounter upon arrival. These signs use a color-coded system that indicates health, flammability, and reactivity risks, which facilitates the quick assessment of dangers during emergencies. Locating these signs at critical access points, such as tank locations and facility entrances, ensures that the necessary information is readily accessible to emergency personnel before they enter potentially hazardous environments.

While vehicles, front desks, and personal protective equipment may display various safety information, they are not the primary locations designated for NFPA 704 signage. Thus, having them prominently placed at the aboveground tanks and entrances serves the essential function of ensuring that first responders are adequately informed about the hazards they might face, thereby enhancing safety and preparedness in emergency situations.
