risk overview
health hazards: the product of the eyes, skin, mucous membranes and upper respiratory tract irritation and corrosion.
explosion hazard: the product is not flammable, toxic, corrosive, irritating, can cause burns. [2]
first aid measure
skin contact: immediately remove contaminated clothing, rinse with plenty of water for at least 15 minutes. medical treatment.
eye contact: immediately lift the eyelids, rinse with plenty of water or saline for at least 15 minutes. medical treatment.
inhalation: quickly from the scene to the fresh air. maintain airway patency. if breathing is difficult, give oxygen. if breathing stops, immediately carry on artificial respiration. medical treatment.
ingestion: rinse with water to drink milk or egg white. medical treatment. [2]
protection measures
engineering control: closed operation, local exhaust.
respiratory protection: dust concentration in the air exceeds the standard, you must wear a self absorption filter dust masks. emergency rescue or evacuation, should wear air breathing apparatus.
eye protection: wear chemical safety goggles.
body protection: wear anti poison infiltration work clothes.
hand protection: wear rubber gloves.
other protection: the work is finished, the shower is changing. pay attention to personal hygiene. regular physical examination. [2]
fire protection measures
hazardous combustion products: carbon monoxide, carbon dioxide, hydrogen chloride, sodium oxide.
fire fighting methods: fire fighters have to wear full body fire protective clothing, in the upper hand to fire. when the fire as far as possible the containers from fire to open. [2]
leak emergency treatment
emergency treatment: isolated leakage pollution area, limit access. cut off the fire source. the proposed emergency handling personnel wear a dust mask (full cover), wear protective clothing. to avoid dust, carefully sweep up, placed in the bag to move to a safe place. if a large number of leaks, with plastic cloth, canvas cover. collect and recycle or transport to waste disposal sites. [2]
operation disposal and storage
operating notes: airtight operation, partial discharge. operator must undergo special training, strictly comply with the operating procedures. suggested that the operator wear self - absorption filter dust masks, wear chemical safety glasses, wear anti poison penetration work clothes, wear rubber gloves. avoid producing dust. avoid contact with oxidizing agents, acids and bases. when moving to light light unloading, prevent damage to packaging and containers. emergency handling equipment equipped with leakage. empty containers may contain harmful substances.
storage note: store in a cool, ventilated warehouse. away from the fire, heat source. should be with the oxidant, acid, alkali, food chemicals stored separately, should not be mixed. fire fighting equipment with corresponding variety and quantity. the storage area should be equipped with appropriate material containing leakage.
