Section 721.633 - Aluminosilicates, phospho-(a)Chemical substance and significant new uses subject to reporting.(1) The chemical substance identified as aluminosilicates, phospho- (PMN P-98-1275 and SNUN S-11-10; CAS No. 201167-69-3) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section.(2) The significant new uses are: (i)Protection in the workplace. Requirements as specified in § 721.63(a)(4), (b), and (c) . When determining which persons are reasonably likely to be exposed as required for § 721.63(a)(4) engineering control measures (e.g., enclosure or confinement of the operation, general and local ventilation) or administrative control measures (e.g., workplace policies and procedures) shall be considered and implemented to prevent exposure, where feasible. The following NIOSH-certified respirators with an APF of at least 50 meet the requirements of § 721.63(a)(4) : NIOSH-certified air-purifying, tight-fitting full-face respirator equipped with N100 (if oil aerosols absent), R100, or P100 filters; NIOSH-certified powered air-purifying respirator equipped with a tight-fitting full facepiece and high efficiency particulate air (HEPA) filters; NIOSH-certified supplied-air respirator operated in positive pressure demand or continuous flow mode and equipped with a hood, or helmet or tight-fitting facepiece. As an alternative to the respiratory requirements listed here, a manufacturer or processor may choose to follow the New Chemical Exposure Limit (NCEL) provisions listed in the TSCA section 5(e) consent order for these substances. The NCEL is 0.1 mg/m3 as an 8-hour time weighted average verified by actual monitoring data.(ii)Hazard communication program. Requirements as specified in § 721.72 (a), (b), (c), (d), (g)(1)(ii), (g)(1)(iv), (g)(1) (vii), (g)(2)(i), (g)(2)(iv), and (g)(5) .(b)Specific requirements. The provisions of subpart A of this part apply to this section except as modified by this paragraph.(1)Recordkeeping. Recordkeeping requirements as specified in § 721.125(a), (b), (c), (d), (f), (g), and (h) are applicable to manufacturers and processors of this substance.(2)Limitations or revocation of certain notification requirements. The provisions of § 721.185 apply to this section.(3)Determining whether a specific use is subject to this section. The provisions of § 721.1725(b)(1) apply to this section. 65 FR 81399 , Dec. 26, 2000, as amended at 80 FR 37164 , June 30, 2015
