Storage method
Announce
edit
Store in a cool and ventilated warehouse.Keep away from kindling and heat sources.The package shall be sealed and shall not contact with air.It shall be stored separately from alkali, and mixed storage is strictly prohibited.The storage area shall be equipped with leakage emergency treatment equipment and appropriate materials.
Leakage emergency treatment
Announce
edit
Evacuate the personnel in the leakage contaminated area to a safe area quickly, isolate them, and strictly restrict access.It is recommended that emergency treatment personnel wear self-contained positive pressure respirators and acid and alkali resistant work clothes.Do not touch the leakage directly.Cut off the leakage source as much as possible.
Small amount of leakage: sprinkle soda ash on the ground, and then flush with a large amount of water, which will be diluted and put into the waste water system.
Large amount of leakage: build a dike or dig a pit to receive.Transfer to tank car or special collector with pump, and recycle or transport to waste disposal site for disposal.
Protective measures

edit
Eye protection: protection has been made in respiratory system protection.
Body protection: wear rubber acid and alkali resistant clothes.
Hand protection: wear rubber acid and alkali resistant gloves.
Respiratory system protection: wear a self-priming filtered gas mask (full face mask) or an air respirator when you may be exposed to its smoke.It is recommended to wear oxygen respirator during emergency rescue or evacuation.
Other protection: smoking, eating and drinking are prohibited at the work site.After work, take a shower and change clothes.Store the clothes contaminated by poisons separately and use them after washing.Keep good hygiene habits.
