Ready Mix Concrete <br /> Safety Data Sheet <br /> --ording To Federal Register/Vol.77,No.58/Monday,March 26,2012/Rules And Regulations And According To The Hazardous Products Regulation (February 11,2015). <br /> ronic Symptoms: If dust is generated, repeated exposure through inhalation may cause cancer or lung disease. Pre-existing lung <br /> ulseases such as emphysema or asthma may be aggravated by exposure to dusts. Pulmonary function may be reduced by inhalation <br /> of respirable crystalline silica.Also lung scarring produced by such inhalation may lead to a progressive massive fibrosis of the lung <br /> which may aggravate other pulmonary conditions and diseases and which increases susceptibility to pulmonary tuberculosis. <br /> Progressive massive fibrosis may be accompanied by right heart enlargement, heart failure,and pulmonary failure. Smoking <br /> aggravates the effects of exposure.Some studies show that exposure to respirable crystalline silica (without silicosis)or that the <br /> disease silicosis may be associated with the increased incidence of several autoimmune disorders such as scleroderma (thickening of <br /> the skin),systemic lupus erythematosus, rheumatoid arthritis and diseases affecting the kidneys.Silicosis increases the risk of <br /> tuberculosis. Some studies show an increased incidence of chronic kidney disease and end-stage renal disease in workers exposed to <br /> respirable crystalline silica. <br /> 4.3. Indication of Any Immediate Medical Attention and Special Treatment Needed <br /> If exposed or concerned,get medical advice and attention. If medical advice is needed, have product container or label at hand. <br /> SECTION <br /> 5.1. Extinguishing Media <br /> Suitable Extinguishing Media:Water spray, dry chemical,foam,carbon dioxide. <br /> Unsuitable Extinguishing Media: Do not use a heavy water stream. Use of heavy stream of water may spread fire. <br /> 5.2. Special Hazards Arising From the Substance or Mixture <br /> Fire Hazard: Not flammable. <br /> Explosion Hazard: Product is not explosive. <br /> Reactivity: Reacts slowly with water forming hydrated compounds, releasing heat and producing a strong alkaline <br /> solution until reaction is substantially complete. May react exothermically with water releasing heat.Adding an acid to a base or <br /> base to an acid may cause a violent reaction. <br /> 5.3. Advice for Firefighters <br /> Precautionary Measures Fire: Exercise caution when fighting any chemical fire. Under fire conditions, hazardous fumes will be <br /> esent. <br /> firefighting Instructions: Do not allow run-off from fire fighting to enter drains or water sources. Do not breathe fumes or vapors <br /> from fire. Use water spray or fog for cooling exposed containers. <br /> Protection During Firefighting: Do not enter fire area without proper protective equipment,including respiratory protection. <br /> Hazardous Combustion Products:Carbon oxides(CO, CO2).Silicon oxides. <br /> Reference to Other Sections <br /> Refer to Section 9 for flammability properties. <br /> SECTION <br /> 6.1. Personal Precautions, Protective Equipment and Emergency Procedures <br /> General Measures:Avoid breathing dust, mist, spray. Do not get in eyes, on skin, or on clothing. <br /> 6.1.1. For Non-Emergency Personnel <br /> Protective Equipment: Use appropriate personal protective equipment(PPE). <br /> Emergency Procedures: Evacuate unnecessary personnel. <br /> 6.1.2. For Emergency Personnel <br /> Protective Equipment: Equip cleanup crew with proper protection. <br /> Emergency Procedures:Ventilate area. Upon arrival at the scene,a first responder is expected to recognize the presence of <br /> dangerous goods, protect oneself and the public, secure the area,and call for the assistance of trained personnel as soon as <br /> conditions permit. <br /> 6.2. Environmental Precautions <br /> Prevent entry to sewers and public waters. <br /> 6.3. Methods and Materials for Containment and Cleaning Up <br /> For Containment:Place spilled material into a container.Avoid contact with skin.Wear appropriate protective equipment as <br /> described in Section 8.Scrape wet concrete and place in container.Allow material to dry or solidify before disposal. Do not wash <br /> concrete down sewage and drainage systems or into bodies of water(e.g. streams). Contain any spills with dikes or absorbents to <br /> event migration and entry into sewers or streams.As an immediate precautionary measure, isolate spill or leak area in all <br /> .,rections. <br /> 04/13/2017 EN(English US) 3/10 <br />
