Second, the rectification plan: expansion section Third, the rectification sequence: rectification from top to bottom, until the hidden dangers are rectified. Fourth, the bracket material: 9# I-shaped steel trapezoidal shed support for permanent support, the length of not less than 1.2m thickness of not less than 5.0cm of the wooden back. V. Support specifications: upper net width: 1.5m, lower net width: 2.2m, net height: 2.0m. Sixth, the precautions in the rectification: 1. The need to use friction gold metal strut before expanding and reinforcing the original shed roof beams, reinforcing its range of not less than 6.0m, then, taken out and then back to help small plate between the original help shed opening to the desired cross section Excavate a column with a depth of not less than 20 cm for permanent support. 2. After the new bracket is erected, the original bracket can be withdrawn after the backing is completed. 3. The length of the small plate used for backing shall not be less than 1.2m, the thickness shall not be less than 5cm, and the number of small plates on each side shall not be less than 5. 4. The vacant part behind the small board is filled with incombustible vermiculite. 5. The remaining materials on the shift must be cleaned to ensure the cleanliness of the workplace. 6. When transporting outwards, it must be ensured that the manhole damper of the wind well is in safe operation. Potassium hydroxide, also known as lye is an inorganic compound with the chemical formula KOH. Also commonly referred to as caustic potash, it is a potent base that is marketed in several forms including pellets, flakes, and powders. It is used in various chemical, industrial and manufacturing applications. Potassium hydroxide is also a precursor to other potassium compounds. Potassium hydroxide is used in food to adjust pH, as a stabilizer, and as a thickening agent. This ingredient has been considered as generally safe as a direct human food ingredient by the FDA, based upon the observance of several good manufacturing practice conditions of use. In addition to the above uses, potassium hydroxide is also used in making soap, as an electrolyte in alkaline batteries and in electroplating, lithography, and paint and varnish removers. Liquid drain cleaners contain 25 to 36% of potassium hydroxide. Medically, potassium hydroxide (KOH) is widely used in the wet mount preparation of various clinical specimens for microscopic visualization of fungi and fungal elements in skin, hair, nails, and even vaginal secretions,. Recently, it has been studied for efficacy and tolerability in the treatment of warts. It was determined that topical KOH solution was found to be a safe and effective treatment of plane warts.
