2000-07 Portland Cement MSDS No. 718 <br /> Handling wet cement can cause dermatitis_Cement when wet is quite alkaline and this alkali action on the skin <br /> contributes strongly to cement contact dermatitis since it may cause drying and defatting of the skin which is <br /> followed by hardening,cracking, lesions developing,possible infections of lesions and penetration by soluble salts. <br /> Cement contact dermatitis(CCD)may occur when contact shows an allergic response,which may progress to <br /> sensitization.Sensitization is due to soluble chromates(chromate compounds)present in trace amounts in some <br /> cements,cement products. Soluble chromates readily penetrate intact skin. <br /> Cement dermatitis can be characterized by fissures,eczematous rash,dystrophic nails,and dry skin;acute contact <br /> with highly alkaline mixtures may cause localized necrosis. <br /> Ingestion:Considered an unlikely route of entry in commercial/industrial environments. <br /> The material is harmful if swallowed. <br /> The dust is discomforting to the gastrointestinal tract. <br /> Carcinogenicity:NTP-Not listed;IARC-Not listed;OSHA-Not listed;NIOSH-Not listed;ACGIH-Not listed; <br /> EPA-Not listed;MAK -Not listed. <br /> Chronic Effects:Cement eczema may be due to chromium in feed stocks or contamination from materials of <br /> construction.Sensitization to chromium may be the leading cause of nickel and cobalt sensitivity and the high <br /> alkalinity of cement is an important factor in cement dermatoses. <br /> Repeated,prolonged severe inhalation exposure may cause pulmonary edema and rarely,pulmonary fibrosis.Workers <br /> may also suffer from dust-induced bronchitis with chronic bronchitis reported in 17%of a group occupationally <br /> exposed to high dust levels. <br /> Data suggests that occupational exposure to Portland cement dust may lead to a higher incidence of chronic respiratory <br /> symptoms and a reduction of ventilatory capacity. <br /> Section 4- First Aid Measures <br /> Inhalation:Remove to fresh air. <br /> Encourage patient to blow nose to ensure clear breathing passages. <br /> Ask patient to rinse mouth with water but to not drink water. <br /> Seek immediate medical attention. <br /> Eye Contact:Immediately hold the eyes open and flush continuously for at least 15 minutes with fresh running water. <br /> Ensure irrigation under eyelids by occasionally lifting the upper and lower lids. <br /> Transport to hospital or doctor without delay.Removal of contact lenses after an eye injury should only be undertaken <br /> by skilled personnel. <br /> Skin Contact:Immediately remove all contaminated clothing,including footwear(after rinsing with water). <br /> Wash affected areas thoroughly with water(and soap if available). <br /> Seek medical attention in event of irritation. <br /> Ingestion:Contact a Poison Control Center. <br /> Do NOT induce vomiting.Give a glass of water. <br /> After first aid,get appropriate implant,paramedic,or community medical support <br /> Note to Physicians:Treat symptomatically as for strong alkaline material. <br /> Section 5 -Fire-Fighting Measures <br /> Flash Point:Noncombustible <br /> Autoignition Temperature:Not applicable <br /> LEL:Not applicable <br /> UEL:Not applicable O <br /> Extinguishing Media:If small amounts are involved in a fire,there is no restriction on the type of <br /> extinguisher.Otherwise,use LARGE AMOUNTS of water to absorb heat generated. _ <br /> General Fire Hazards/Hazardous Combustion Products:Noncombustible. <br /> Not considered to be a significant fire risk;however,containers may bum. <br /> Decomposes on heating and produces toxic fumes of caustic compounds. Fire Diamond <br /> Fire Incompatibility:No known incompatibility with normal range of industrial materials. <br /> Fire-Fighting Instructions:Contact fire department and tell them location and nature of hazard. <br /> Wear breathing apparatus plus protective gloves for fire only. Prevent,by any means available,spillage from entering <br /> drains or waterways. <br /> Use fire fighting procedures suitable for surrounding area. <br /> Do not approach containers suspected to be hot. <br /> Cool fire-exposed containers with water spray from a protected location. <br /> If safe to do so,remove containers from path of fire. <br /> Equipment should be thoroughly decontaminated after use. <br /> Section 5 -Accidental Release Measures <br /> Small Spills:Clean up all spills immediately.Avoid contact with skin and eyes. <br /> Wear protective clothing,gloves,safety glasses and dust respirator. <br /> Copyright r,Soon Geniurn Poblishing Corporation.Any comvwrcial use or reproduction without the publishers permission is pruhibiwd.
