Fire extinguisher signs are the most numerous safety signs in workplaces and public buildings today. Yet most existing signs are not compliant with the latest NFPA and ISO standards, using, instead, poorly designed arrow-with-text forms that date back to the early 1900s. Clarion fire extinguisher signs are different; they comply with the latest NFPA and ISO fire safety symbol standards, giving you a state-of-the-art means to implement OSHA’s requirement to mark the location of all fire extinguishers.
