1、Material Safety Data Sheet(Waterglass)1. Product name WaterglassCAS-No. :1344-09-81.2 Company :Shanghai JiaDingWaterglass Factory 2COMPOSITION/INFORMATION ON INGREDIENTSFormula:Na2O3SiMolecular Weight: 122.063. HAZARDS IDENTIFICATION3.1 IngestionBurns of the esophagus and less commonly the stomach m
2、ay occur after caustic ingestion; the absence of oral mucosal injury does not reliably exclude esophageal burns. Patients with stridor, drooling or vomiting are more likely to have esophageal burns.3.2 InhalationStridor, dyspnea, upper airway injury, and pulmonary edema, especially following inhalat
3、ion of vaporized caustics, may occur.3.3 SkinSevere skin irritation and/or burns may occur.3.4 EyesSee Inhalation.3.5 HazardsOxides from metallic fires are a severe health hazard. Fire may produce irritating, corrosive and/or toxic gases.4. FIRST AID MEASURES4.1 IngestionMucosal if no respiratory co
4、mpromise is present, dilute immediately with milk or water; no more than 8 ounces in adults and 4 ounces in children. Gastric ipecac contraindicated. Consider insertion of a small, flexible nasogastric or orogastric tube to suction gastric contents after recent large ingestions; the risk of further
5、mucosal injury must be weighed against potential benefits.4.2 InhalationMove patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required.
6、 Treat bronchospasm with beta2 agonist and corticosteroid aerosols.4.3 Skin ContactRemove contaminated clothes. Irrigate exposed skin with copious amounts of water for at least 15 minutes or longer, depending on concentration, amount and duration of exposure to the chemical. A physician may need to
7、examine the area if irritation or pain persist.4.4 EyesHome irrigation - exposed eyes should be irrigated with copious amounts of water for at least 30 minutes. An examination should always be performed. Ophthalmologic consultation should be obtained. Medical facility: irrigate with sterile 0.9% Sal
8、ine for at least an hour or until the cul-de-sacs are free of particulate matter and returned to neutrality (confirm with pH paper).5. FIREFIGHTING MEASURESFire FightingExtinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use wa
9、ter in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.6. ACCIDENTAL RELEASE MEASURESSmall spills/leaksBuild dikes to contain flow as necessary. Neutralize spilled material with crushed limestone, soda ash, or
10、 lime.7. HANDLING AND STORAGE7.1 Storage RequirementStore in a cool, dry location in a sealed container.7.2 HandlingContainers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid), all hazard precautions given in the data shee
