Labelmaster's NFPA® Standard Signs communicate to firefighters and emergency responders the hazards that might be associated with a chemical under emergency fire or spill conditions. Our full line of NFPA® products (Numbers and Symbols, Signs and Training) not only communicates potential hazards to employees and responders but provides you with the tools to help teach your workers how to use the NFPA system properly. These meet the NFPA 704 standard and are printed with explanations of health, fire and instability precautions. To display the appropriate NFPA hazard ratings for use in an emergency response situation, use 4-in., self-sticking vinyl numbers and symbols that can be seen legibly from a distance of 200 feet. NFPA numbers and symbols are sold separately. The pressure-sensitive signs are printed on durable, weather-resistant vinyl and measure 15 x 15 in.
