IDENTIFICATION OSHA Emergency Overview

Principle Routes of Exposure

Personal Protective Equipment 1. TOXIC – Contains quartz, Inhalation: Normal use of this product mix for crystalline silica. construction purposes is not believed to cause GHS WHMIS 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. 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 wet product mix may result in chemical burns, dermatitis, skin blisters or corneal damage. 3. IRRITANT Caustic Inhalation and, Eye and Skin Contact Contact with dust from dry mix may cause skin, eye and respiratory irritation. _______________________ _____________________________________

Environmental hazards

Uncured cementitious materials or finely divided GHS (crushed) concrete material is an environmental hazard, which may adversely affect fish and other aquatic habitat. Do not use crushed concrete as fill near any aquatic habitat. 1 A. CHRONIC HAZARDS: 1. Crystalline Silica

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.
