PARAGON PLASTIC CEMENT

Hazardous Ingredients

Masonry cement clinker (CAS # 65997-15-1) – approximately – 63. 5 - 96% by weight. ACGIH TLV-TWA (2000) = 10 mg total dust/m3 OSHA PEL (8-hour TWA) = 50 million particles/ft Calcium Carbonate (CAS # 1317-65-3) – approximately 25.0 -30.0 % by weight ACGIH TLV-TWA (2000) 10 mg total dust/m3 OSHA PEL (8-hour TWA) = 15 mg total dust/m3 OSHA PEL (8-hour TWA) = 5 mg respirable dust/m3 Gypsum: (CAS # 7778-18-9) – approximately – 4.0-6.5 % by weight. ACGIH TLV-TWA (2000) = 10 mg total dust/m3 OSHA PEL (8-hour TWA) = 15 mg total dust/m3 OSHA PEL (8-hour TWA) = 5 mg respirable dust/m3 Respirable quart: (CAS # 14808-60-7) – greater than 0.1% by weight. ACGH TLV-TWA (2000) = 0.05 mg respirable quartz dust/m3 OSHA PEL (8-hour TWA) = (10 mg respirable dust/m3 (percent silica +2)) Trace Ingredients: Trace amount of naturally occurring chemicals might be detected during chemical analysis. Trace constituents may include up to 0.75% insoluble residue. Some of which may be free crystalline silica, calcium oxide (Also known as lime or quick lime), magnesium oxide, potassium sulfate, chromium compounds, and nickel compounds. SECTION III – HAZARD IDENTIFICATION Emergency Overview: Portland cement is a light gray powder that poses little hazard. A single short-term exposure to the dry powder is not likely to cause harm. However, exposure to sufficient duration to wet Portland cement can cause serious, potentially irreversible tissue destruction (skin or eye) in the form of chemical caustic burns. The same type of tissue destruction can occur if wet or moist areas of the body are exposed for sufficient duration to dry Portland cement. Potential Health Effects: Eye contact, skin contact, inhalation and ingestion. Effects Resulting from Eye Contact: Exposure to airborne dust may cause immediate or delayed irritation or inflammation. Eye contact with large amounts of dry powder or splashes of wet Portland cement may cause effects ranging from moderate eye irritation to chemical burns or blindness. Such exposure requires immediate first aid (see Section IV) and medical attention to prevent significant damage to the eye. Effects Resulting from Skin Contact: Discomfort or pain can not be relied upon as an alert to hazardous skin exposure. Consequently, the only effective means of avoiding skin injury or illness involves minimizing skin contact, particularly with wet cement. An exposed person may not feel discomfort until hours after the exposure has ended and significant injury has occurred. Dry Portland cement contacting wet skin or exposure to moist or wet Portland cement may cause severe skin effects including thickening, cracking or fissuring of the skin. Prolonged exposure can cause severe skin damage in the form of alkali chemical burns. Some individuals may exhibit an allergic response upon exposure to Portland cement, possibly to trace elements of chromium. The response may appear in a variety of forms ranging from mild rash to severe skin ulcers. Individuals already sensitized may react to their first contact with the product. Other individuals may first experience this effect after years of contact with Portland cement products. Effects Resulting from Inhalation: Portland cement may contain trace amounts of free crystalline silica. Prolonged exposure to respirable free silica can aggravate other lung conditions and cause silicosis, a disabling and potentially fatal lung disease. SECTION III – HAZARD IDENTIFICATION CONTINUATION: Effects Resulting from Inhalation: Exposure to Portland cement may cause irritation to the moist mucous membranes of the nose, throat and upper respiratory system. It may also leave unpleasant deposits in the nose. Effect Resulting from Ingestion: Although small amount of dust are not known to be harmful, ill effects are possible if larger quantities are consumed. Portland cement should not be eaten. Carcinogenic Potential: Portland cement is not listed as a carcinogen by NTF, OSHA, or IARC. It may however, contain trace amounts of substances listed as carcinogens by these organizations. Crystalline silica, a potential trace level contaminate in Portland cement, is now classified by IARC as known human carcinogens (Group I). NTP has characterized respirable silica as “Reasonably anticipated to be (a) carcinogen” Medical conditions which may be aggravated by, inhalation or dermal exposure: Pre-existing respiratory and lung diseases. Unusual (hyper) sensitivity to hexavalent chromium (chromium +6) salts. SECTION IV – FIRST AID
