Warning!


DO NOT BREATHE THIS MATERIAL
Never use this material without an air-supplied respirator.

Blasting sand contains fine silica dust. If you breathe in this dust you may suffer severe, irreversible lung damage and death. Medical reports also link inhalation of silica dust to lung cancer and crippling arthritis. You must never use this material without having a government-approved respirator. The work area must also be thoroughly ventilated by the use of forced ventilation during and after use of this product.

Prior to use or handling, you are advised to review and thoroughly understand all health precautions outlined in the Material Safety Data Sheet (MSDS) provided to your employer by the supplier of this product.

RESPIRATOR PROTECTION

It is a violation of federal safety laws (OSHA) for employers to require workers to use this material without full respiratory protection. The federal laws that apply are: 29CFR 1910.134; 29CFR 1910.1000; and 29CFR 1910.94.

It is recommended that users of the blast sand use OSHA approved, positive pressure, air-fed breathing hood respirators. The positive air pressure will prevent silica dust from being drawn into the respirator. Continue to wear the respirator until all airborne silica dust has been exhausted from the work area.

VENTILATION

Finely divided silica dust is nearly invisible. Work areas must be thoroughly ventilated with forced ventilation fans sufficient to exhaust all silica dust and provide a complete air exchange every five minutes. Continue ventilation after sand blasting operations have been completed.

OTHER PROTECTIVE EQUIPMENT

Silica dust can also be harmful to your skin and eyes. You need to wear tight goggles, heavy rubber gloves. Clothing should be tight fitting at the cuffs, neck and ankles to prevent silica dust from contacting your body.

WARNING SYMPTOMS AND FIRST AID


If you experience shortness of breath, coughing and lung and/or throat irritation these may be early warning signs that silica dust is producing a medical condition such as silicosis. See your doctor at once if such symptoms occur. Swelling of the joints, and joint pain, may signal the start of arthritis, which is also reported to be aggravated by silica exposure. Again, if such symptoms occur seek immediate medical attention.

If eye contact and irritation take place, flush your eyes continuously with clear cold water for at least 15 minutes and then see your doctor for an examination and possible treatment.

Safety Notes: Federal safety regulations require that employers train workers in the safe use of sand blasting materials and equipment and that they hold periodic safety meetings to assure that safety precautions are being maintained. Report any concerns about these issues to OSHA, at (800) 321-6742.
