Calcium hydroxide is alkaline and corrosive to human skin. Potassium hydroxide, like strong calcium oxide, is highly alkaline and corrosive, posing a risk of burns to tissues. It must be used with caution!
The specific chemical properties of potassium hydroxide are as follows:
It has alkaline properties, is easily soluble in water, and has strong corrosiveness. Dissolve in water and release a large amount of heat. And due to the decomposition of carbohydrates by hydroxides, the risk of acid corrosion is more severe. Skin corroded by potassium hydroxide usually presents deep burns and is difficult to heal. Once the eyes or skin come into contact with potassium hydroxide, the injured area should be quickly rinsed with water for more than 15 minutes and seek medical attention immediately; Oral administration can burn the digestive tract and can be fatal.
Therefore, when using potassium hydroxide, it is advisable to wear a gas mask, chemical safety goggles, and work clothes (made of anti-corrosion materials). Wear rubber gloves (synthetic rubber). After work, take a shower and change clothes. Pay attention to personal cleanliness and hygiene.
Storage and transportation of potassium hydroxide
1. Transportation precautions: During railway transportation, steel drum packaging can be transported by gondola cars. The packaging should be complete during shipment and the loading should be secure. During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or be damaged. It is strictly prohibited to mix and transport flammable or combustible materials, acids, edible chemicals, etc. Transport vehicles should be equipped with leakage emergency response equipment during transportation;
2. Storage precautions: Store in a cool, dry, and well ventilated warehouse. Keep away from sparks and heat sources. The humidity inside the warehouse should not exceed 85%. The packaging must be sealed and protected from moisture. It should be stored separately from flammable (combustible) substances, acids, etc., and mixed storage should be avoided. The storage area should be equipped with suitable materials to contain leaks;
3. Packaging method: Solids can be tightly sealed in 0.5mm thick steel drums, with a net weight of no more than 100 kilograms per drum; Plastic bags or two-layer kraft paper bags with full or medium opening steel drums; Thread mouth glass bottles, iron cap pressure mouth glass bottles, plastic bottles or ordinary wooden boxes outside metal barrels (cans); A threaded glass bottle, plastic bottle, or tinned thin steel plate barrel (can) with a bottom plate full of checkered boxes, fiberboard boxes, or plywood boxes; Tinned thin steel drums (cans), metal drums (cans), plastic bottles or corrugated cardboard boxes with metal hoses.
The above is an introduction to personal protective measures for potassium hydroxide. Only by taking good personal protective measures can we reduce the skin irritation caused by this product, and centralized treatment should be carried out after each work is completed to avoid dust irritation. Otherwise, once injured, it is difficult to recover, especially its corrosiveness can cause significant harm to the human body.
