Fire extinguishing methods. Firefighters must wear full body acid and alkali resistant firefighting clothing. Extinguishing agent:Dry sand and earth. Water is prohibited.

spill disposal

 Isolate the leaking contaminated area and restrict access. It is recommended that emergency personnel wear dust masks (full face masks) and anti-virus clothing. Do not come into direct contact with the spill. Small spills: Avoid raising dust and collect with a clean shovel in a dry, clean, covered container. Also rinse with plenty of water, dilute the wash water and put it into the wastewater system. Large spills: Cover with plastic sheeting or canvas. Remove under expert supervision.

storage and transportation precautions

 ①Precautions for operation: closed operation, local exhaust. Operators must be specially trained and strictly follow the operating procedures. It is recommended that the operator wear a hood-type electric air supply filtering dust respirator, wear anti-poison penetration work clothes, wear rubber gloves. Avoid generating dust. Avoid contact with acids, amines, alcohols and esters. When handling, load and unload gently to prevent damage to packaging and containers. Equip with emergency equipment to deal with leakage. Empty containers may retain hazardous materials.

②Storage Precautions:Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat source. Packaging must be sealed, do not get wet. Should be stored separately from acids, amines, alcohols, esters, etc., do not mix storage. The storage area should be equipped with suitable materials to contain the leakage.

③Transportation Notes: When transported by rail, the dangerous goods should be loaded in strict accordance with the dangerous goods loading table in the "Dangerous Goods Transportation Rules" of the Ministry of Railways. Packaging should be complete at the time of shipment, and loading should be stable. During transportation, we should make sure that the container will not leak, collapse, fall or be damaged. It is strictly prohibited to mix and transport with acid, amine, alcohol, ester, edible chemicals and so on. Transportation vehicles should be equipped with leakage emergency treatment equipment. During transportation, it should be protected from exposure to sunlight, rain and high temperature.
