Relative density (water=1): 0.8580
Solubility: soluble in benzene, ether and perchlorethylene. Water that is hydrolyzed to release free hydrochloric acid.
Uses: for the production of a variety of organosilicon compounds, is the production of hexamethyldisilazane nitrogen (amine) alkyl and the main raw material of hexamethyldisiloxane.
Pathways: inhaled, ingested, percutaneous absorption.
The respiratory tract and the eyes, skin and mucous membranes have a strong stimulating effect. Inhalation can cause throat, bronchial spasms, dropsy and chemical pneumonia, pneumonia, pulmonary edema and death. Exposed workers tend to have eye pain, tearing, cough, headache, nausea, vomiting, wheezing, irritability, itching and other skin.
Hazardous characteristics: flammable, high fever case, the fire or contact with the oxidant, combustion caused a risk of explosion. In case of heat or water heat liberation and emit toxic corrosive flue gas. Corrosive. Combustion (decomposition) products: carbon monoxide, carbon dioxide, silicon oxide, hydrogen chloride. Fire fighting methods: water cooling containers, if possible to move containers from the scene empty Department. Fire extinguishing agent: carbon dioxide, dry, sandy soil. Do not use water or foam.
Closed operation, full ventilation. The operator must go through specialized training, strict adherence to rules. Proposed operators wear self-absorption filter respirators (full cover), wearing chemical protective safety glasses, wear protective overalls on infiltration, wear rubber gloves. Prevent vapor leakage into the workplace air. Avoid contact with the bases and the like. When moving to light light unloading, prevent damage to packaging and containers. Equipped with spill response equipment. Empty containers may be harmful residues.
Store in a cool, dry, well-ventilated warehouse. Away from fire, heat source. Storage temperature should not exceed 37 ℃, Keep container closed. Should be stored separately from acids, bases, etc., avoid mixing reservoir. Explosion-proof lighting, ventilation facilities. Prohibit the use of mechanical equipment and tools easy to produce sparks. Storage areas should be equipped with spill response equipment and materials suitable host.
When complete packaging to shipment, loading should be safe. During transport to ensure that the container does not leak, did not fall, do not fall, no damage. Strictly prohibited and acids, bases, food chemicals mixed mixed operation. Transport transport vehicles should be equipped with spill response equipment. Transit should be anti-exposure, rain, high temperature. According to the provisions road transport routes, not in residential areas and densely populated areas.
Skin contact: Immediately remove contaminated clothing, rinse for at least 15 minutes with plenty of water. Medical treatment. Eye contact: immediately filed eyelid, with plenty of water or saline thoroughly washed at least 15 minutes. Medical treatment. Inhalation: rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. Medical treatment. Fresh into: oral intake of water were found to blues or egg white. Medical treatment.
ACCIDENTAL RELEASE AND DISPOSAL:
Rapid withdrawal from air leakage personnel to a safe area, and isolation and strict restrictions on access. Cut off the fire source. Recommended emergency personnel wearing self-contained breathing apparatus, wearing fire protective clothing. Do not direct contact with leakage. Cut off the source of leakage as far as possible, prevent access to sewers, Pai Hung-ditch restrictive space. A small leak: sand, dry stone or soda ash mixed. You can also use non-flammable dispersant flour emulsion wash, lotion diluted into the wastewater system. Large leak: to build a causeway or trenching asylum. Foam coverage, lower vapor disasters. Ex pump used to transfer tankers or exclusive collector, recycling or shipped to the waste disposal sites.
Engineering controls: production process sealed, fully ventilated. Provide safety shower and eyewash equipment protection.
Respiratory protection: its possible exposure to vapor, should wear self-absorption filter respirators (full cover). Emergency rescue or evacuation, it is recommended to wear self-contained breathing apparatus compartment.
Eye protection: Wear protective chemical safety glasses.
Physical protection: wear protective overalls on infiltration.
Hand protection: Wear rubber gloves.
Maximum acceptable concentration MAC (mg / m3): failure to develop standard
Other protection: work site prohibit smoking, eating and drinking. After work, take a shower. Pay attention to personal hygiene.
