Metal Halide And Mercury Vapor Lighting Hazards In Schools
The Food and Drug Administration has identified more than 100 incidents of exposure to short-wave ultraviolet (UV) radiation from broken and unshielded high-intensity metal halide and mercury vapor light bulbs in high school gyms. Some of these incidents have resulted in severe eye and skin burns. As a result, the FDA recommends the following actions to ensure the safety of students, spectators and staff:
- Replace any fixture that is damaged.
- Replace any bulbs that are missing, broken or punctured.
- Ensure light bulbs are installed in appropriate fixtures. Self- extinguishing “T” type bulbs should be installed in open fixtures or fixtures with wire guards. Non-self-extinguishing “R” type bulbs should only be installed in light fixtures that fully enlcose the bulb and have a lens of glass or plastic to protect the bulb from breakage.
- Make certain that those individuals responsible for maintenance of the lighting system understand the manufacturer’s warnings, as well as any federal, state and local guidelines.
