Spill emergency treatment
Emergency treatment: Quickly evac話放uate personnel from the leaked co地中ntaminated area to a safe ar明分ea and isolate them to strictl些藍y restrict access Cut o煙生ff the fire. It is r道科ecommended that emer朋火gency handlers wear self-contain理姐ed positive-pressure respira姐場tors and antistatic work clo做文thes. Do not touch the spil資們l directly. Cut off th姐兒e source of the leak if possib得書le. Prevent from flowing務算 into restricted space錯玩s such as sewers and floo好場d drains. Small leaks得站: Adsorb or absorb with sa舊媽nd or other non-comb作一ustible materials. It c通西an also be rinsed wit暗明h a large amount of water and d業訊iluted into the waste子明 water system. Large spills: b拿坐uild dikes or dig pits fo哥鄉r containment. Cover with f明姐oam to reduce steam disaste銀大r. Transfer to tanke是用r or special collector 制商with explosion-proof pump, recycle or t有靜ransport to waste disposal place
Handling and storage
Precautions for operation: Close用雪d operation and enhanced分樂 ventilation. Operators must be spe有相cially trained and strictly abide 票媽by the operating procedures長知. It is recommended that operators w數件ear filter-type gas masks (hal南工f-masks), chemical safe睡雜ty protective glasses, antistati商師c work clothes, and ru購有bber gloves. Away from fire and heat s店動ources, smoking is stri森訊ctly prohibited in the workplace兵裡. Use explosion-proof ventilation syst低通ems and equipment. Prevent vapors from信輛 leaking into the workplace air. Avo很影id contact with oxidants, acids and alk綠靜ali metals. When filling, th業鄉e flow rate should be controlle拍哥d, and there should b老去e a grounding device to 家樹prevent static electr飛離icity accumulation. Equipped with西件 the corresponding variety and quanti現師ty of fire fighting e樂空quipment and leakage emergency舞要 treatment equipment. Empty co讀匠ntainers may remain harm影西ful.
Storage Precautions: Store in紅近 a cool, ventilated warehouse. 場生Keep away from fire and heat s什煙ources. The storage temperature s小唱hould not exceed 30 ℃. Keep containe市報r tightly closed. It s木拍hould be stored separ數土ately from oxidants, acids路藍, alkali metals, etc.線靜 Avoid mixed storage. Use explo好還sion-proof lighting and ventilation fac輛友ilities. Prohibit the use of spa術懂rk-prone machinery a就花nd equipment. The storage area間暗 should be equipped with leakage emerg到人ency treatment equipment and su去哥itable containment materials.
