Multiwalled carbon nanotubes
a Chemical substance and significant new uses subject to reporting.
1 The chemical substance identified generically as multiwalled carbon nanotubes PMN P18182 is subject to reporting under this section for the significant new uses described in paragraph a2 of this section. The requirements of this section do not apply to quantities of the substance that have been:
i Embedded or incorporated into a polymer matrix that itself has been reacted cured;
ii Embedded in a permanent solid/
polymer form that is not intended to undergo further processing, except mechanical processing; or iii Incorporated into an article as defined at 40 CFR 720.3c.
2 The significant new uses are:
i Protection in the workplace.
Requirements as specified in 721.63a1, 3 through 6, and c.
When determining which persons are reasonably likely to be exposed as required for 721.63a1 and 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 721.63a5, respirators must provide a National Institute for Occupational Safety and Health NIOSH assigned protection factor APF of at least 50. For purposes of 721.63a6, the airborne forms of the substance include particulate.
ii Industrial, commercial, and consumer activities. It is a significant new use to use an application method that generates a dust, mist, or aerosol, unless such application method occurs in an enclosed process. It is a significant new use to use the substance other than for heat transfer, heat storage, thermal emission, and general temperature management in heat-generating systems such as electronics, to improve mechanical properties or electrical conductivities of other materials or
