Grinding/cutting/drilling of masonry, concrete, metal andother materials with silica in their composition may giveoff dust or mists containing crystalline silica. Silica is abasic component of sand, quartz, brick clay, granite andnumerous other minerals and rocks. Repeated and/orsubstantial inhalation of airborne crystalline silica cancause serious or fatal respiratory diseases, includingsilicosis. In addition, California and some otherauthorities have listed respirable crystalline silica as asubstance known to cause cancer. When cutting suchmaterials, always follow the respiratory precautionsmentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metal andother materials can generate dust, mists and fumescontaining chemicals known to cause serious or fatalinjury or illness, such as respiratory disease, cancer,birth defects or other reproductive harm. If you areunfamiliar with the risks associated with the particularprocess and/or material being cut or the composition ofthe tool being used, review the material safety datasheet and/or consult your employer, the materialmanufacturer/supplier, governmental agencies such asOSHA and NIOSH and other sources on hazardousmaterials. California and some other authorities, forinstance, have published lists of substances known tocause cancer, reproductive toxicity, or other harmfuleffects.
Control dust, mist and fumes at the source wherepossible. In this regard use good work practices andfollow the recommendations of the manufacturers orsuppliers, OSHA/NIOSH, and occupational and tradeassociations. Water should be used for dustsuppression when wet cutting is feasible. When thehazards from inhalation of dust, mists and fumes cannotbe eliminated, the operator and any bystanders shouldalways wear a respirator approved by NIOSH/MSHA forthe materials being used.
