US Patent 10074295 Photoluminescent identifier system for firefighting equipment

The present system provides a lightweight fire-resistant photoluminescent identifier system for firefighters, which is suitable for use on the firefighter's facemask, as well as other equipment. The system is lightweight and provides individual recognition of an individual firefighter. The identifier system lights up automatically in a low-light environment without batteries, yet prevents glare to the firefighter using the system. The components that comprise the system are fire-resistant to temperatures up to and exceeding 500 degrees Fahrenheit to facilitate personal recognition of the individual in dark and low-light areas.
