§ 721.11700 Ashes (residues), reactions products with substituted tricarboxylic acid, silicic acid (H4SiO4) tetra-Et ester and 2-[[3-(trialkoxysilyl)alkoxy]methyl] oxirane (generic) (P-20-115).
(a) Chemical substance and significant new uses subject to reporting. (1) The chemical substance identified generically as ashes (residues), reactions products with substituted tricarboxylic acid, silicic acid (H4SiO4) tetra-Et ester and 2-[[3-(trialkoxysilyl)alkoxy]methyl] oxirane (PMN P-20-115) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section. The requirements of this section do not apply to quantities of the substance after they have been completely incorporated into a polymer matrix.
(2) The significant new uses are:
(i) Protection in the workplace. Requirements as specified in § 721.63(a)(4) through (6), (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. For purposes of § 721.63(a)(5), respirators must provide a National Institute for Occupational Safety and Health (NIOSH) assigned protection factor (APF) of at least 50. For purposes of § 721.63(a)(6), the airborne form(s) of the substance include: particulate (including solids or liquid droplets). For purposes of § 721.63(b), the concentration is set at 0.1%.
