(a) Chemical substance and significant new uses subject to reporting.
(a)(1) The chemical substance identified as copper gallium indium selenide (PMN P-10-424; CAS No. 144972-86-1) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section.
(a)(2) The significant new uses are:
(a)(2)(i) Protection in the workplace. Requirements as specified in §721.63(a)(4), (a)(6)(i), (b) (concentration set at 0.1 percent), and (c). The following NIOSH-certified respirators with an assigned protection factor (APF) of at least 10 meet the minimum requirements for §721.63(a)(4):
(A) NIOSH-certified air-purifying, tight-fitting half-face respirator equipped with N100 (if oil aerosols absent), R100, or P100 filters;
(B) NIOSH-certified air-purifying, tight-fitting full-face respirator equipped with N100 (if oil aerosols absent), R100, or P100 filters;
(C) NIOSH-certified powered air-purifying respirator equipped with a loose-fitting hood or helmet and high efficiency particulate air (HEPA) filters;
(D) NIOSH-certified powered air-purifying respirator equipped with a tight-fitting facepiece (either half-face or full-face) and HEPA filters; or
(E) NIOSH-certified supplied-air respirator operated in pressure demand or continuous flow mode and equipped with a hood or helmet, or tight-fitting facepiece (either half-face or full-face).
(1) As an alternative to the respiratory requirements listed in paragraph (a)(2)(i), a manufacturer, importer, or processor may choose to follow the new chemical exposure limit (NCEL) of 1.5 mg/m3 as an 8-hour time-weighted-average. Persons who wish to pursue NCELs as an alternative to the §721.63 respirator requirements may request to do so under §721.30.
(2) [Reserved]
(a)(2)(ii) Hazard communication program. Requirements as specified in §721.72(a), (b), (c), (d), (e) (concentration set at 0.1 percent), (f), (g)(1)(ii), (g)(2)(ii), (g)(2)(iv) (use respiratory protection or maintain workplace airborne concentrations at or below an 8-hour time-weighted average of 1.5 mg/m3), and (g)(5).
(b) Specific requirements. The provisions of subpart A of this part apply to this section except as modified by this paragraph.
(b)(1) Recordkeeping. Recordkeeping requirements as specified in §721.125(a), (b), (c), (d), (f), (g), and (h) are applicable to manufacturers, importers, and processors of this substance.
(b)(2) Limitations or revocation of certain notification requirements. The provisions of §721.185 apply to this section.
