Safety and Handling Recommendations for Abrasives
DuPont Starblast® abrasives, as shipped, do not pose any inhalation health hazard because Starblast® contains essentially no particles in the respirable size range. However, if during handling or use, the Starblast® particles are broken down to a size that can be inhaled, the dust may be harmful to the respiratory system.
DuPont staurolite abrasive products may contain up to 5% crystalline silica (quartz). Long-term overexposure to respirable crystalline silica may cause silicosis. The U.S. Department of Labor (OSHA)* has ruled that an employee's exposure to particulates, not otherwise regulated, should not exceed 5 mg/m3
(respirable dust), 15 mg/m3
(total dust), 8-hr time weighted average (TWA). When these limits might be exceeded, employees should wear dust masks or respirators approved by NIOSH for such dusts.
* Due to changing governmental regulations, such as those in the Department of Transportation, Department of Labor, U.S. Environmental Protection Agency, and the Food and Drug Administration, references herein to governmental requirements may be superseded. Each user should consult and follow the current governmental regulations, such as: Hazards Classifications, Labeling, Food Use Clearances, Worker Exposure Limitations, and Waste Disposal Procedures for the products described in this literature.
Gear up for safety
Begin with safety. Be sure your gear includes a long-sleeved protective suit, gloves, an OSHA-approved air-fed helmet and respirator, with an air source that can't be contaminated by you or your coworkers' blasting. By following all local, state, and federal regulatory requirements, you help protect yourself. And using the right abrasive can help protect others around you.
