what are the hazard of caustic baths?Acid and caustic baths complement each other. Acid baths are best for removing scale, rust and oxide coatings from metals, caustic baths for removing oil, soils buffing compounds and paints. The most common caustics are sodium hydroxide and potassium hydroxide ( also called caustic soda and caustic potash, respectively). Most caustic baths also contain a variety of special purpose additives. Many baths use electrodes and pass electric current through the fluid to improve the cleaning effects. These electrodes also release gas bubbles, which increases the mist above the tank.Caustis in concentraded solutions are even more corrosive to the skin and eyes than acids. Direct contact with caustics can result indeep, painful burns to the skindestroying the eye tissue if splashed into the eyesLike acids, caustic vapours, mists and sprays irriate the eyes, nose, throat and lungs. persistent vapour exposure can cause a hole to form in the cartilage between te nostrils of the nose ( called a " perforated septum''). Lower mist levels can cause dermatitis. Also, like acids, very vapour exposures can cause pulmonary edema and death
