Labelmaster's National Fire Protection Association (NFPA) Diamond Labels are designed for easy identification of chemical hazards by firefighters and emergency responders who are concerned with burning, spilled or exploding materials. These safety labels meet the NFPA 704 standard and are printed with numerical ratings for health hazards, fire hazards, instability and specific hazards associated with a chemical under emergency fire or spill conditions. These labels display the NFPA diamond graphic with spaces for you to fill in NFPA hazard warning information that might be associated with a chemical during a fire emergency. The 15 x 15-in. labels are printed on pressure-sensitive, weather-resistant vinyl and are sold individually.
