Dust generated when grinding or cutting nonmetallic materials may be very fine, abrasive, flammable, and/or explosive. Material being removed may contain crystalline silica, quartz, glass fibers, and other fine materials. Prolonged breathing of the dust may cause cancer and irreversible lung damage. Wear goggles, gloves, and a dust respirator certified by the National Institute for Occupational Safety and Health (NIOSH) and by the Mine Safety and Health Administration (MSHA).In the event of contact with the skin, flush the skin with plenty of water. If dust material gets into the eyes, flush the eyes with an approved flushing system and seek medical attention. Before smoking or eating, clean hands thoroughly. Keep the work site clean and dispose of all dust and particles in containers approved for flammable materials.Refer to the dust handling instructions in this publication for correct disposal of the dust.
Paint and products used in painting may be flammable and hazardous. Read, understand, and follow instructions for use on the container. Wear NIOSH/MSHA certified respiratory protection.
