British Standard 5499-2:1986 (BS 5499-2:1986) describes specifications for self-luminous fire safety signs. Several committees collaborated on this British Standard including Fire Standards Committee, British Sign Association, Chartered Institution of Building Services’ Engineers, Department of Health and Social Security, and several others (which are listed on the front cover of this document). This part of BS 5499 is in compliance with Radiation Protection Standards for Gaseous Tritium Light Devices. The water-soluble tritium content of each gaseous tritium light source is determined using dose rate measurements under guidelines provided by the National Radiological Protection Board. Various precautions are noted and suggested throughout this standard. As part of Identification and Labeling in Section 6, manufacturers are expected to clearly indicate the date of supply, serial number, the word “RADIOACTIVE,” the word “TRITIUM,” and other safety precautions. In addition, Figures 1 and 2 provide illustrations for a glow-wire with thermocouple and a glow-wire test apparatus, for which both provide supporting information to Appendix B on Flammability Test.
