D.C. Mun. Regs. tit. 22-B, § 10856
10856.1 The provisions of this section apply to any high-intensity mercury vapor discharge lamp that is designed, intended, or promoted for illumination purposes and is manufactured or assembled after March 7, 1980, except as described in § 10856.6.
10856.2 As used in this section the following definitions apply:
10856.3 Each high-intensity mercury vapor discharge lamp shall:
(a) Meet the requirements of either § 10856.5 or § 10856.9; and
(b) Be permanently labeled or marked in such a manner that the name of the manufacturer and the month and year of manufacture of the lamp can be determined on an intact lamp and after the outer envelope of the lamp is broken or removed. The name of the manufacturer and month and year of manufacture may be expressed in code or symbols, provided the manufacturer has previously supplied the Director, Center for Devices and Radiological Health, with the key to the code or symbols and the location of the coded information or symbols on the lamp.
10856.4 In lieu of permanently affixing or inscribing tags or labels on the product as required by §§ 10845.2 and 10846.1, the manufacturer of any high-intensity mercury vapor discharge lamp may permanently affix or inscribe such required tags or labels on the lamp packaging uniquely associated with the applicable lamp.
10856.5 Each self-extinguishing lamp manufactured after March 7, 1980 shall cease operation within a cumulative operating time not to exceed fifteen (15) minutes following complete breakage or removal of the outer envelope (with the exception of fragments extending fifty millimeters (50 mm) or less from the base shell).
10856.6 Each self-extinguishing lamp manufactured after September 7, 1981, shall cease operation within a cumulative operating time not to exceed fifteen (15) minutes following breakage or removal of at least three square centimeters (3 cm²) of contiguous surface of the outer envelope.
10856.7 Each self-extinguishing lamp shall be clearly marked with the letter "T" on the outer envelope and on another part of the lamp in such a manner that it is visible after the outer envelope of the lamp is broken or removed.
10856.8 Lamp packaging for each self-extinguishing lamp shall clearly and prominently display:
(a) The letter "T"; and
(b) The wording: "This lamp should self-extinguish within fifteen (15) minutes after the outer envelope is broken or punctured. If such damage occurs, TURN OFF AND REMOVE LAMP to avoid possible injury from hazardous shortwave ultraviolet radiation.".
10856.9 Any high-intensity mercury vapor discharge lamp that does not comply with § 10856.5 shall be clearly and legibly marked with the letter "R" on the outer
envelope and on another part of the lamp in such a manner that it is visible after the outer envelope of the lamp is broken or removed.
10856.10 Lamp packaging for each high-intensity mercury vapor discharge lamp that does not comply with § 10856.5 shall clearly and prominently display:
(a) The letter "R"; and
(b) The wording "WARNING: This lamp can cause serious skin burn and eye inflammation from shortwave ultraviolet radiation if outer envelope of the lamp is broken or punctured. Do not use where people will remain for more than a few minutes unless adequate shielding or other safety precautions are used. Lamps that will automatically extinguish when the outer envelope is broken or punctured are commercially available.".
10856.11 Advertising for any high-intensity mercury vapor discharge lamp that does not comply with § 10856.5 shall prominently display the following wording: "WARNING: This lamp can cause serious skin burn and eye inflammation from shortwave ultraviolet radiation if outer envelope of the lamp is broken or punctured. Do not use where people will remain for more than a few minutes unless adequate shielding or other safety precautions are used. Lamps that will automatically extinguish when the outer envelope is broken or punctured are commercially available.".
10856.12 Any high-intensity mercury vapor discharge lamp under test for compliance with the requirements set forth in § 10856.5 shall be started and operated under the following conditions as applicable:
(a) Lamp voltage, current, and orientation shall be those indicated or recommended by the manufacturer for operation of the intact lamp;
(b) The lamp shall be operated on a reference ballast;
(c) The lamp shall be started in air that has a temperature of twenty five plus or minus five degrees Celsius (25+/-5° C). Heating and movement of the air surrounding the lamp shall be that produced by the lamp and ballast alone;
(d) If any test is performed in an enclosure, the enclosure shall be not less than two hundred twenty-seven thousandth cubic meters (0.227 m³ (eight cubic feet (8 cu. ft.)); and
(e) Any lamp designed to be operated only in a specific fixture or luminaire that the lamp manufacturer supplies or specifies shall be tested in that
fixture or luminaire. Any other lamp shall be tested with no reflector or other surrounding material.
