氫氧化鉀又名苛性鉀、苛性堿、鉀灰，外觀為白色粉末或片狀固體，是一種常見的化工產(chǎn)品，不論是在工業(yè)上還是在實(shí)驗(yàn)室中都經(jīng)常會(huì)看見它的身影。但是氫氧化鉀屬于危險(xiǎn)化學(xué)品，具有強(qiáng)堿性及腐蝕性，還會(huì)造成人體中毒。

Potassium hydroxide, also known as caustic potash, caustic soda and potassium ash, is a common chemical product in the form of white powder or flake solid. It is often seen in industry or laboratory. However, potassium hydroxide is a dangerous chemical with strong alkalinity and corrosivity, which can also cause human poisoning.

強(qiáng)堿性及腐蝕性：其表現(xiàn)為在與皮膚接觸時(shí)會(huì)有燒灼作用，可溶解蛋白質(zhì)，形成堿性變性蛋白質(zhì)。溶液或粉塵濺到皮膚上，尤其濺到黏膜，可產(chǎn)生軟痂。溶液濃度越高，溫度越高，作用越強(qiáng)。濺入眼內(nèi)，不僅可損傷角膜，而且能使眼部深組織損傷。

Strong alkalinity and corrosivity: It is characterized by cauterization when contacting with skin, which can dissolve protein and form alkaline denatured protein. If the solution or dust splashes on the skin, especially on the mucous membrane, it can produce soft scabs. The higher the solution concentration and temperature, the stronger the effect. Splashing into the eye can not only damage the cornea, but also damage the deep tissues of the eye.

如果我們?cè)谑褂脮r(shí)不小心發(fā)生接觸，要迅速進(jìn)行自救應(yīng)對(duì)：工作時(shí)應(yīng)防止觸及皮膚和眼睛，如不慎觸及時(shí)，可用流水洗滌受損部位，然后濕敷5%的醋酸、酒石酸、鹽酸或檸檬酸溶液；如濺人眼內(nèi)，應(yīng)用流水或生理鹽水仔細(xì)緩慢洗滌10～30min，然后點(diǎn)入2%的奴佛卡因或0.5%的地卡因溶液。操作時(shí)應(yīng)穿由結(jié)實(shí)布制作的工作服，戴橡皮手套、袖套、圍裙，穿膠鞋等勞保用品，手上宜涂敷中性和疏水軟膏。

If we accidentally come into contact when using, we should quickly carry out self rescue response: prevent touching the skin and eyes when working. If we accidentally touch in time, wash the damaged part with running water, and then wet apply 5% acetic acid, tartaric acid, hydrochloric acid or citric acid solution; If it splashes into the eyes, wash it carefully and slowly with running water or normal saline for 10~30min, and then add 2% novocaine or 0.5% dicaine solution. During operation, workers should wear work clothes made of solid cloth, rubber gloves, sleeves, aprons, rubber shoes and other labor protection appliances, and neutral and hydrophobic ointment should be applied on hands.

毒性：長(zhǎng)期吸入少量會(huì)造成肺損害，其急性毒性為L(zhǎng)D50273mg/kg（大鼠經(jīng)口）。所以一定要避免長(zhǎng)時(shí)間的從事氫氧化鉀相關(guān)工作，注意佩戴相應(yīng)防具，盡量避免食入。如果不小心食入，要立即用水漱口，并用飲牛奶或蛋清，嚴(yán)重者立即就醫(yī)。

Toxicity: Long term inhalation of a small amount will cause lung damage, and its acute toxicity is LD50273mg/kg (rat oral). Therefore, it is necessary to avoid engaging in potassium hydroxide related work for a long time, pay attention to wearing corresponding protective equipment, and try to avoid ingestion. If you accidentally ingest it, rinse your mouth with water immediately, and drink milk or egg white. If it is serious, seek medical advice immediately.

由于氫氧化鉀還會(huì)污染水體，具有爆炸風(fēng)險(xiǎn)，在不慎發(fā)生泄露事故時(shí)要立即隔離泄漏污染區(qū)，限制出入。建議應(yīng)急處理人員戴防塵面具，穿防酸堿工作服。不要直接接觸泄漏物。

As potassium hydroxide can also pollute water bodies and has explosion risk, in case of accidental leakage accident, immediately isolate the leakage pollution area and restrict access. It is recommended that emergency treatment personnel wear dust masks and acid and alkali proof work clothes. Do not touch the leakage directly.

小量泄漏：用潔凈的鏟子收集于干燥、潔凈、有蓋的容器中。也可以用大量水沖洗，洗水稀釋后放入廢水系統(tǒng)。

Small amount of leakage: collect it in a dry, clean and covered container with a clean shovel. A large amount of water can also be used for flushing, and the diluted washing water will be put into the wastewater system.

大量泄漏：收集回收或運(yùn)廢物處理場(chǎng)所處置。

Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.
