The red, yellow and blue sections are labeled on scale of 0 to 4 0 'minimal hazard' to 4, 'severe hazard'. The square is divided into four sections, color coded: Red - flammability blue - health hazard yellow - reactivity/instability White - special hazard, such as oxidizers, water reactive or Asphyxiating gas. The signs are intended to be mounted on the exteriors of buildings, storage tanks and storage areas. NFPA 704 is a standard developed by the National Fire Protection Association for warning first responders to hazards posed by hazardous materials stored in a building or facility. If a fire alarm system does not automatically call the fire department, a "When Alarm Sounds - Call Fire Department" sign must be posted at all fire alarm pull station/call points and at any external fire alarm notification appliances. If a connection does not cover an entire building, such a connection feeding fire sprinklers that are only in a new addition, the area covered must be stated on the sign. Signs must also state what is fed by the connection. On existing buildings, where the connection is not visible from these places, it must clearly marked with a red and white sign, with "FDC", short for "Fire Department Connection", in 6 inches (150 mm) letters, with any other lettering or arrows being 2 inches (51 mm) tall. The International Code Council's International Building Code requires that all fire standpipe and fire sprinkler connections must be visible from the roadway or fire department access in new construction. Numerous markings have been developed to better aid firefighters and other first responders to warn of hazards from hazardous materials, location of utility shut-offs, fire alarm and sprinkler control panels, construction and condition of the building. In 2017, New York City announced a formal project to go through all city-owned structures and remove any remaining fallout shelter signage, citing the fact no structure still had a functioning shelter and would not be usable in an emergency. Following the end of the program there was no organized effort by the federal government reclaim shelter supplies and signage, resulting in most shelters being abandoned in situ until building owners cleared away the shelter's supplies and signage during subsequent renovations or demolition projects. įollowing the ending of funding for fallout shelters in the late 1970s.
