Principle Routes of Exposure

Personal Protective Equipment 1. TOXIC –

Contains

Inhalation: Normal use of this product mix for quartz, crystalline silica. construction purposes is not believed to cause additional acute toxic effects. However, repeated GHS WHMIS overexposure to very high levels of respirable crystalline silica (quartz, cristobalite, tridymite) for periods as short as six months have caused acute silicosis. Acute silicosis is a rapidly progressive, incurable lung disease that is typically fatal. Symptoms include (but are not limited to); shortness of breath, cough, fever, weight loss, and chest pain. 2. CORROSIVE MATERIAL Caustic Eye and Skin Contact: Eye contact with the wet product mix may cause irritation or burns; skin contact may cause irritation. Long term skin or eye contact with a wet product mix may result in chemical burns, dermatitis, skin blisters or 3. IRRITANT corneal damage. Caustic Inhalation and, Eye and Skin Contact Contact with dust from dry mix may cause skin, eye and respiratory irritation. _______________________________________ ____________________ Uncured cementitious material or finely divided

Environmental hazards

crushed) concrete material is an environmental hazard, GHS which may adversely affect fish and other aquatic habitat. Do not use crushed concrete and fly ash 1 products as fill near any aquatic habitat. A. CHRONIC HAZARDS: 1. Crystalline Silica: ACGIH and OSHA have determined that adverse effects are not likely to occur in the workplace provided exposure levels do not exceed the appropriate TLVs/PELs. However, because of the wide variation in individual susceptibility, lower exposure limits may be appropriate for some individuals, including persons with pre-existing medical conditions such as those described under Sub-chronic and Chronic Effects. 2. CEMENT, FLY A wet product mix exhibits caustic, abrasive and dehydrating properties that will cause irritation or burns to skin and eyes. ASH and AGGREGATES Contact from dust resulting from handling and mixing dry concrete products, breaking or crushing of hardened products may cause eyes and skin irritation. It will also cause upper respiratory tract irritation. B. SUBCHRONIC AND CHRONIC HEALTH EFFECTS: Pulmonary Diseases: Excessive exposure to particulates (dust containing crystalline silica) over an extended period of time may result in the development of silicosis and other pulmonary diseases. Carcinogenicity: The classifications below are based on experimental studies with animals and epidemiologic studies of workers exposed to respirable crystalline silica. IARC: classified respirable crystalline silica (quartz) as Group 1, a known carcinogen in humans. NTP: classifies as (1) human carcinogen ACGIH: classified as (A2) suspect human carcinogen NIOSH: classified as a potential occupational carcinogen California Proposition 65 Warning: This product will expose you to respirable crystalline silica which is “known in the State of California to cause cancer and to other substances which are known to the State of California to cause cancer, birth defects and other reproductive harm.” Canada WHMIS Classification: 1. Products containing quartz (crystalline Silica) are typically classified as Division 2 A (very toxic) if the chemical has been shown to be carcinogenic, mutagenic (to reproductive cells), reproductive toxic, sensitizer (to respiratory tract or chronic (long-term) toxicity (at low doses). 2. Portland Cement is a nuisance dust. 3. Fly Ash classified as irritant. C. ACUTE HAZARDS: Eye Contact Direct contact with dust may cause irritation by mechanical abrasion. Direct contact may cause irritation by mechanical abrasion. If burning, itching, Skin Contact redness and pain or other symptoms persist, consult a physician. Long term skin contact with the wet product mix may result in chemical burns or dermatitis. Skin Absorption Not expected to be a significant exposure route. Ingestion Ingestion of large amounts may cause gastrointestinal irritation and blockage. Inhalation Normal use of this product mix for construction purposes is not believed to cause additional acute toxic effects. However, repeated overexposure to very high levels 2 of respirable crystalline silica (quartz, cristobalite, tridymite) for periods as short as six months have caused acute silicosis. Acute silicosis is a rapidly progressive, incurable lung disease that is typically fatal. Symptoms include (but are not limited to); shortness of breath, cough, fever, weight loss, and chest pain.

Medical Conditions Generally Aggravated by Exposure

E. Excessive dust exposure may aggravate any existing respiratory disorders or diseases. Possible complications of allergies resulting in irritation to skin, eyes and respiratory passage may occur from excessive exposure to dusts. If any symptoms persist, consult a physician. Dusts may irritate the nose, throat, and respiratory tract by mechanical abrasion. Coughing, sneezing, and shortness of breath may occur following exposures in excess of appropriate exposure limits. Use of natural sand and gravel for construction purposes is not believed to cause additional acute toxic effects. However, repeated overexposure to very high levels of respirable crystalline silica (quartz, cristobalite, tridymite) for periods as short as six months have caused acute silicosis. Acute silicosis is a rapidly progressive, incurable lung disease that is typically fatal. Symptoms include (but are not limited to); shortness of breath, cough, fever, weight loss, and chest pain.
