SECTION 2: HAZARDS IDENTIFICATION

Potential Health Effects

Route of Exposure Inhalation; skin contact, eye contact, ingestion.
Inhalation Exposure to airborne concentrations above exposure limits may cause irritation of the nose, throat and lungs.
Skin Contact Repeated or prolonged exposure can irritate the skin.
Eye Contact Airborne dust may cause immediate or delayed irritation or inflammation. Contact causes severe burns with redness, swelling, pain and blurred vision. Permanent damage including blindness can result.
Effects of Long-Term (Chronic) Exposure Risk of injury depends on duration and level of exposure. This product contains crystalline silica. Prolonged or repeated inhalation of the respirable crystalline silica can cause silicosis, a seriously disabling and potentially fatal lung disease. See Section 4 for further information.
Carcinogenicity CARCINOGEN. Known to cause: lung cancer.

SECTION 4: FIRST AID MEASURES

First Aid Procedures

Inhalation Move victim to fresh air. Seek medical attention for discomfort or if coughing or other symptoms do not subside.
Skin Contact Quickly take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Wash gently and thoroughly with lukewarm, gently flowing water and non-abrasive soap for 5 minutes.
Eye Contact Immediately flush the contaminated eye(s) with lukewarm, gently flowing water for 15-20 minutes, while holding the eyelid(s) open. If irritation or pain persists, see a doctor.
Ingestion NEVER give anything by mouth if victim is rapidly losing consciousness, or is unconscious or convulsing. DO NOT INDUCE VOMITING. If conscious, give victim a glass of water or milk. Immediately call a Poison Centre or doctor.

Note to Physicians Additional Notes – Silicosis – There are three (3) types of silicosis:

1) Simple chronic silicosis – which results from long-term exposure (more than 20 years) to low amounts of respirable crystalline silica. Nodules of chronic inflammation and scarring provoked by the respirable crystalline silica form in the lungs and chest lymph nodes. This disease may feature breathlessness and may resemble chronic obstructive pulmonary disease (COPD).

2) Accelerated silicosis – occurs after exposure to larger amounts of respirable crystalline silica over a shorter period of time (5-15 years). Inflammation, scarring, and symptoms progress faster in accelerated silicosis than in simple silicosis.

3) Acute silicosis – results from short-term exposure to very large amounts of respirable crystalline silica. The lungs become very inflamed and may fill with fluid, causing severe shortness of breath and low blood oxygen levels.

Progressive massive fibrosis may occur in simple or accelerated silicosis, but is more common in the accelerated form. Progressive massive fibrosis results from severe scarring and leads to the destruction of normal lung structures.
