However, the revised IDLH for titanium dioxide is 5,000 mg/m3 based on being 500 times the OSHA PEL of 10 mg/m3 promulgated in 1989 (500 is an assigned protection factor for respirators and was used arbitrarily during the Standards Completion Program for deciding when the "most protective" respirators should be used for particulates). The delegated regulation classifies titanium dioxide (TiO2) in powder form containing 1 % or more of particles with aerodynamic diameter ≤ 10 μm as a category 2 suspected carcinogen by inhalation. Uses & Benefits. However, for some particulate substances for which no evidence of an IDLH exists, the determination of allowable respiratory protection based on protection factors may result in the assignment of respirators for concentrations that are not likely to be encountered in the occupational environment. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Titanium dioxide is classified as a Group 2B carcinogen as animal studies have linked its inhalation to lung tumor development.

For this draft technical standard, therefore, respirators have been selected on the basis of the assigned protection factor afforded by each device. In early 2018, we reported that the European Chemicals Agency (ECHA) had made a recommendation to the European Commission (EC) to require that titanium dioxide placed on the market as an inhalable powder will require a classification as Carcinogen, Category 2 (i.e. The permissible exposure limit for TiO2 is 15mg/m3, as total dust, expressed as an 8-hour time-weighted average. In addition to this, it also has a number of lesser-known properties, making it a useful ingredient in fighting climate change and preventing skin cancer. [Note: NIOSH recommends as part of its carcinogen policy that the "most protective" respirators be worn for titanium dioxide at any detectable concentration. Therefore, for all such particulate substances it has been arbitrarily determined that only the “most protective” respirators are permitted for use in concentrations exceeding 500 ´ the OSHA PEL (500 ´ 15 mg/m3 is 7,500 mg/m3). CDC twenty four seven. Cancer research. Directorate of Technical Support, EXECUTIVE OFFICES What does this mean?
