Help firefighters and emergency responders easily identify chemical hazards with Labelmaster's NFPA® Diamond Only Signs. Available in 6 x 6-, 10 3/4 x 10 3/4-, 15 x 15- or 24 x 24-in. sizes, these National Fire Protection Association (NFPA) magnetic signs are used by industries and organizations that handle materials that could be involved in an emergency such as a fire or chemical spill. They meet the NFPA 704 standard. To display the appropriate NFPA hazard ratings for health, fire and instability, use 6-in., self-sticking vinyl numbers and symbols that can be seen legibly from a distance of 300 feet, which are sold separately. The signs are made of a durable, exterior-grade material that is ideal for use on storage tanks, and the magnetic backing allows for easy application to steel/ferrous metal surfaces and easy removal for use in other locations around your facility. This full line of products 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.
