NIOSH Safety and Health Topic: Vermiculite
NIOSH is evaluating the potential for asbestos exposure during work with vermiculite from sources other than the mine near Libby. While information continues to be gathered, precautions should be taken to minimize the generation and inhalation of dust during the handling of vermiculite known or presumed to be contaminated by asbestos. As with any dust, workers should avoid prolonged high-level exposures.
Synthetic Mineral Fibers: Health Hazards

Results from animal experiments have led to conservative classifications of certain synthetic mineral fibers as possible human carcinogens. Specifically, insulation glass wool, continuous glass filament, rock (stone) wool, and slag wool are not classifiable as to their carcinogenicity to humans. The following resources aid in recognizing synthetic mineral fiber hazards in the workplace.
