SILICA DUST HAZARD
Exposure to crystalline silica (found in sand, soil and rocks) has been associated with silicosis,
a debilitating and often fatal lung disease. Comply with all applicable rules and regulations for
the workplace. Wear approved respiratory protection or use water spray or other means if there
is no other way to control the dust.
A Silica rule "29 CFR 1929.1153" by the U.S. Occupational Safety and Health (OSHA) indicates a
signicant risk of chronic silicosis for workers exposed to inhaled crystalline silica over a working
lifetime. Refer to the rule for more information regarding exposure limits and hazard prevention.
