![]() The cornea should be stained with fluorescein and examined under a slit lamp. Direct installation is nearly impossible due to blepharospasm. ![]() Place two drops on the medial canthus of the eye then gently pry open the lid. Control pain with a topical anesthetic, such as tetracaine or proparacaine. In the emergency department, use a topical anesthetic and irrigate with a balanced salt solution. With the appearance of coronavirus, interest in sanitizing has increased.īleach is a very good sanitizer it kills coronavirus within a minute of contact with 0.1% dilution of hypochlorite bleach.Įyes: At home, flush with tap water. For concerns and exposures, see the individual exposure MSDS (Material Safety Data Sheet.) There are industrial and concentrated forms of bleach that are used to clean equipment and treat water supplies, which are not covered here. Bleach contains 3% to 8 % sodium hypochlorite (NaOCl) sodium hydroxide (NaOH) is added to slow decomposition. This is the same reaction as cooking an egg in the same fashion, an egg cannot be uncooked.īleach, as subsequently used here, refers to common household bleach. observed that bleaches disinfect by denaturing (unfolding) bacterial proteins, causing them to clump and become useless. Reductions convert double bonds to single bonds, again making them non-reactive to visible light.Īn additional interesting and useful property of bleaches relates to their antimicrobial (disinfecting) properties. Chlorine bleaches work through oxidation they break the chemical bond of the chromophore (a color-producing portion of pigment) rendering it non-reactive with light. īleach is chlorine-based such as calcium hypochlorite (bleaching powder) and non-chlorine (peroxidase-based).īleaching action occurs through oxidation or reduction. Other, less documented, uses include weed killing and preservation of cut flowers. They are frequently used for cleaning and disinfection bleaches kill or control most types of viruses, bacteria, molds, mildews, and algae. Bleach refers to a large class of compounds used to whiten or color-lighten materials.
