Portland Lime MSDS - St Marys Cement

Portland Lime Material Safety Data SheetEngulfment hazardCement can build up or adhere to the walls of a confined space such as a silo, bin, bulk truck, or othercontainer or vessel. The material can be detached, collapse or fall unexpectedly. To prevent burial orsuffocation, do NOT enter a confined space without precautions appropriate to Confined Spaces.Potential Health EffectsRelevant routes of exposure: 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 bylarger amounts of dry powder or splashes of wet masonry cement may cause effects ranging frommoderate eye irritation to chemical burns and blindness. Such exposures require immediate first aid (seeSection 4) and medical attention to prevent significant damage to the eye.Effects Resulting from Skin Contact:Discomfort or pain cannot be relied upon to alert a person to a hazardous skin exposure. Consequently,the only effective means of avoiding skin injury or illness involves minimizing skin contact, particularlycontact with wet lime. Exposed persons may not feel discomfort until hours after the exposure has endedand significant injury has occurred.Exposure to dry lime may cause drying of the skin with consequent mild irritation or more significanteffects attributable to aggravation of other conditions. Dry lime contacting wet skin or exposure to moistor wet masonry cement may cause more severe skin effects including thickening, cracking or fissuringof the skin.Prolonged exposure can cause severe skin damage in the form of (caustic) chemical burns. Some ultrasensitiveindividuals may exhibit an allergic response upon exposure to lime, possibly due to traceamounts of chromium (hexavalent chromium salts). The response may appear in a variety of formsranging from mild rash to severe skin ulcers. Persons already sensitized may react to their first contactwith the product. Other persons may first experience this effect only after years of contact with limeproducts.Effects Resulting from Inhalation:Lime contains significant amounts of free crystalline silica. Prolonged exposure to respirable freecrystalline silica may aggravate other lung conditions. It also may cause delayed lung injury includingsilicosis, a disabling and potentially fatal lung disease, and/or other diseases.Exposure to lime may cause irritation to the moist membranes of the nose, throat, and upper respiratorysystem. It may also leave unpleasant deposits in the nose.Effects Resulting from Ingestion:Ill effects are possible if accidentally consumed.Carcinogenic Potential: See Section 11.Medical conditions which may be aggravated by inhalation or dermal exposurePre-existing upper respiratory and lung diseases.Unusual (hyper) sensitivity to hexavalent chromium salts.Page 2 of 7

Portland Lime Material Safety Data SheetSECTION 4 - FIRST AIDEyes:Immediately flush eyes thoroughly with water. Continue flushing eyes for at least 15 minutes, includingunder lids, to remove all particles. Seek medical attention.Skin:Wash skin with cool water and mild soap or a detergent intended for use on skin. Seek medicaltreatment in all cases of prolonged skin exposure to lime.Inhalation of Airborne Dust:Remove to fresh air. Seek medical help if coughing and other symptoms do not subside. Inhalation ofgross amounts of lime requires immediate medical attention.Ingestion:Do not induce vomiting. If conscious, have the victim drink plenty of water and call a physicianimmediately.SECTION 5 - FIRE & EXPLOSION DATAFlash Point .................................................................NoneLower Explosive Limit ..............................................NoneUpper Explosive Limit ...............................................NoneAuto Ignition Temperature ........................................Not CombustibleExtinguishing Media ..................................................Not CombustibleSpecial Fire Fighting procedures ...............................NoneAlthough lime poses no fire-related hazards, a self-contained breathing apparatus isrecommended to limit exposure to combustion products when fighting any fire.Hazardous Combustion Products ...............................NoneUnusual Fire and Explosion Hazards .........................NoneSECTION 6 - ACCIDENTAL RELEASE MEASURESCollect dry material in a non-reactive container and minimize dust. Wear appropriate personal protectiveequipment as described in Section 8. Scrape up wet material and place in an appropriate container.Allow the material to dry before disposal. Do not attempt to wash lime down drains. Dispose of wastematerial according to local, state and federal regulations (see Section 13).SECTION 7 - HANDLING AND STORAGEKeep lime dry until used. Normal temperatures and pressures do not affect the material. Promptlyremove dusty clothing or that which is wet with lime and launder before reuse. Wash thoroughly afterexposure to dust or wet lime mixtures.Static HazardProperly ground all pneumatic conveyance systems. The potential exists for static build-up and staticdischarge when moving cement powders through a plastic, nonconductive, or non-grounded pneumaticconveyance system. Static discharge may result in damage to equipment and injury to workers.Page 3 of 7

Portland Lime Material Safety Data SheetSECTION 8 - EXPOSURE CONTROLS/PERSONAL PROTECTIONEye protectionWear ANSI- or CSA-approved safety glasses with side shields or goggles. In extremely dustyenvironments and unpredictable environments, wear unvented or indirectly vented goggles to avoid eyeirritation or injury. Contact lenses should not be worn. Provide emergency eyewash stations.Skin ProtectionPrevention is essential. Avoid contact with lime products. Provide emergency shower stations.Periodically wash affected areas with soap and water. Wash again at the end of the work. If irritationoccurs, immediately wash the affected area with soap and water. Clothing saturated with wet limeshould be removed and replaced with clean dry clothing.Where prolonged exposure to lime might occur, wear impervious e.g. cut/abrasion-resistant rubber(Heavyweight Nitrile coated Safety cuff) gloves. Where required, wear boots that are impervious towater to eliminate foot and ankle exposure.Do not rely on barrier creams in place of gloves.Respiratory ProtectionAvoid actions that cause dust to become airborne. Use local or general ventilation to control exposuresbelow applicable exposure limits.Use NIOSH-approved respirators (N95 rating or greater) if an exposure limit is exceeded, or when dustcauses discomfort or irritation.VentilationUse local exhaust, where practicable, or general dilution ventilation to control exposure withinapplicable limits.SECTION 9 - PHYSICAL AND CHEMICAL PROPERTIESAppearance ................................................................Grey or White PowderOdour .........................................................................No Distinct OdourPhysical State .............................................................SolidpH in Water (ASTM D 1293-95) ...............................12 to 13Solubility in Water .....................................................Slightly Soluble (0.1 to 1.0%)Vapour Pressure .........................................................Not ApplicableVapour Density ..........................................................Not ApplicableBoiling Point ..............................................................Not Applicable (i.e., > 1000°C)Melting Point .............................................................Not ApplicableSpecific Gravity (H 2 O = 1.0) .....................................2.95Evaporation Rate ........................................................Not ApplicableSECTION 10 - STABILITY AND REACTIVITYStability: Stable, except in the presence of moisture.

Portland Lime Material Safety Data SheetIncompatibility:Lime is strongly alkaline; it is incompatible with acids, ammonium salts and aluminum metal.Hazardous Decomposition: Lime will react slowly with atmospheric moisture and carbon dioxide toproduce heat, (caustic) calcium hydroxide and calcium carbonate.Hazardous Polymerization: Will not occur.SECTION 11 - TOXICOLOGICAL INFORMATIONCalcium oxide: Corrosive to living tissue.Calcium hydroxideEye: Severe irritant (eye-rbt 10mg SEV)Skin, mucous membrane, respiratory system: Irritant; causes dermatitisIngestion: Mildly toxic (orl-rat LD50: 7340 mg/kg)Crystalline silicaAcute Toxicity: Not acutely toxicChronic Toxicity: Respirable crystalline silica is the chief cause of pulmonary dust disease. Prolongedinhalation of crystalline silica can result in silicosis, a disabling pulmonary fibrosis characterized bygeneralized fibrotic changes, the development of miliary nodules in both lungs, and clinically by shortnessof breath on exertion, decreased chest expansion, lessened capacity for work, dry cough, absence of fever,increased susceptibility to tuberculosis, and characteristic x-ray findings of diffuse discrete nodulationscattered throughout both lung fields. In advanced stages, silicosis can include marked fatigue, extremedyspnea and cyanosis, loss of appetite, pleuritic pain and total incapacity to work. The disease can result indeath either from cardiac failure or from destruction of lung tissue, with resultant anoxemia.International Agency for Research on Cancer (IARC), The National Toxicology Program (NTP), orOccupational Safety and Health Administration (OSHA) do not specifically list lime as a carcinogen.Crystalline silica, a natural contaminant in lime, is classified as a carcinogen: IARC Group 1 “known tobe carcinogenic to humans”; ACGIH Group 2A “suspected human carcinogen” (limited evidence ofcarcinogenicity in humans and sufficient evidence in experimental animals with relevance to humans);NTP indicates that crystalline silica is reasonably anticipated to be a carcinogen (Group 2).Chromates and Nickel CompoundsCement products may contain trace amounts of hexavalent chromium and nickel compounds. Solublechromates in cement products have been stated to be the cause of cement dermatitis in some workers.Inorganic nickel compounds – pure or in trace amounts – are not absorbed through the skin in amountssufficient to cause systemic intoxication. However, their capability to cause contact dermatitis insensitized individuals is well known.SECTION 12 - ECOLOGICAL INFORMATIONEcotoxicity: No recognized unusual toxicity to plants or animals.Page 5 of 7
