Cleanup Methods
Ventilate area of spill. Collect spilled material in the most convenient and safe manner for reclamation or for disposal in a secured sanitary landfill.
Grades: crude; washed; air-floated; USP; fibrous (99.5%, 99.95%).
Talc, when it is isolated as a pure mineral, has a composition of 63.6% SiO2, 21.89% MgO, and 4.75% H2O. However, as an industrial commodity, talc rarely approaches theoretical purity.
When the ultra fine grinds are used (Mistron grades), they contribute to large surface areas, are non-reactive with sensitive toxicants and can be used in wettable powders.
Exposure Standards and Regulations
The Approved Drug Products with Therapeutic Equivalence Evaluations List identifies currently marketed prescription drug products, incl talc, approved on the basis of safety and effectiveness by FDA under sections 505 of the Federal Food, Drug, and Cosmetic Act.
Certification of this color additive when used in amounts consistent with good manufacturing practice to color drugs generally is not necessary for the protection of the public health, and therefore batches thereof are exempt from the certification pursuant to section 721(c) of the act.
Substances migrating to food from cotton and cotton fabrics used in dry food packaging that are generally recognized as safe for their intended use, within the meaning of section 409 of the Act. Talc is included on this list.
Substances migrating to food from paper and paperboard products used in food packaging that are generally recognized as safe for their intended use, within the meaning of section 409 of the Act. Talc is included on this list.
Drug products containing certain active ingredients offered over-the-counter (OTC) for certain uses. A number of active ingredients have been present in OTC drug products for various uses, as described below. However, based on evidence currently available, there are inadequate data to establish general recognition of the safety and effectiveness of these ingredients for the specified uses: talc is included in astringent drug products.
Other Preventative Measures
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Measures for health protection of workers exposed to talc dusts include wetting in extractive processes, provision of adequate exhaust ventilation ... in milling and packing operations, supplemented by use of respiratory protective devices by workers and periodic medical exam ... including chest x-rays, pulmonary function tests ... and EKG ... .
There is little question but that the dust of nonfibrous talc, consisting almost entirely of platiform talc crystals and containing no asbestos, carries a relatively small respiratory hazard that must be controlled. The degree to which controls should be applied to talc dust should depend upon its asbestos content. /SRP: however, control may be indicated due to the OSHA nuisance dust standard./

Disposal Methods
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
