Do not use bleach on electronic equipment, optical equipment or unpainted stainless steel, Undiluted bleach and other disinfectants must not go down the drain or be mixed with other materials, Only 1:10 dilutions of bleach that have been mixed with adequate levels of protein (such as those found in tissue culture media containing fetal bovine serum) can be poured down the drain, Undiluted bleach is substantially more reactive than diluted bleach, and has even been reported to generate toxic gases such as cyanogen and chloramine when mixed with Luria broth in a ~1:1 ratio, Use stock or working bleach solutions in a well ventilated area, Work in a certified chemical fume hood when using volumes greater than 1000mL, Purchase and use the lowest volume and concentration necessary, Do not use bleach in diluted concentrations greater than 10% unless working with prions, Avoid contact with eyes, skin, and clothing, Verify the SDS and manufacturer’s guidelines for chemical compatibility before mixing bleach, Never mix bleach with incompatible chemicals, an unknown chemical, or mixture. Sodium hypochlorite, the active ingredient in chlorine bleach, is routinely used in the laboratory to decontaminate surfaces and equipment or deactivate biological materials by inactivating vegetative bacteria, fungi, lipid and non-lipid viruses, and other liquid specimens. Store below eye level with compatible chemicals (Stanford Compatible Storage Group E). Univar stocks bleach at over 85 locations scattered throughout the United States. DNA/RNA Kit Incompatible Warning:​ ​Some trademarked reagents and “kits” used in the lab may contain hazardous materials and/or ingredients that are incompatible with bleach. For disinfection of most biologicals (Exception: prions and prion-like proteins), after dilution, working bleach solutions must contain between 0.5% and 2% sodium hypochlorite to be an effective disinfectant. It is an anhydrous unstable compound which can decompose explosively. It consists of hypochlorite anion and sodium cation. The chlorine gas comes from the electrolysis of salt water. Prepare a fresh working dilution … Create a hazardous waste tag and request a pickup (, Attach a waste tag and collect waste separately so that bleach or acidic solutions are not accidentally added to sample preparation kit waste, Visit Water Planning and Stewardship Website for information on Stanford’s. The molar mass of sodium hypochlorite is 74.44 g/mol. Disadvantages. This widely available product is commonly used as either a whitening and disinfecting agent in laundry or an all-purpose disinfectant with broad applications. Sodium hypochlorite is the active ingredient in most household bleaches. Prepare a fresh working dilution of sodium hypochlorite weekly and indicate the preparation date on the bottle. Safety is a primary concern at manufacturing plants because of the presence of volatile chlorine gas. Sodium Hypochlorite Poisoning is the accidental or intentional intake (swallowing, breathing-in, or skin contact) of any product containing the compound. It has a sweetish and chlorine-like odour. It is unstable as a solid, but solutions of up to 40% are commercially available that contain NaOH and NaCl as byproducts of the preparation: Bleach is the generic name for any chemical product which is used industrially and domestically to remove color from a fabric or fiber or to clean or to remove stains in a process called bleaching.

While working with sodium hypochlorite, safety measures have to be taken to protect workers and the environment. Low levels of exposure may result in eye and oral mucous membrane irritation, dizziness, and nausea – while exposure to high levels may be fatal. Sodium hypochlorite is a strong liquid oxidizing agent and has a greenish or yellowish hue. This is an ionic compound consisting of the hypochlorite anion (ClO-) bonded sodium metal cation (Na+). Use of bleach solutions with lower hypochlorite concentrations will not provide the proper level of disinfection. Sodium hypochlorite is a strong liquid oxidizing agent and has a greenish or yellowish hue. Forms toxic gases (e.g., chloramine, chlorine, and hydrogen cyanide) and can form highly reactive compounds. It reacts with acids to form chlorine gas, ketones to form chloroform, ammonia to form chloramines, and with various other compounds, both organic and inorga… Boiling or splashing hazard if mixed with bleach. Bleach is very reactive and if it mixes with incompatible chemicals, it can produce high hazard by-products and toxic gases. Bleach is not stable at dilute concentration. "Sodium Hypochlorite" is it's scientific name but some of it's common names are "Bleach", "Chlorine Bleach" or "Liquid Bleach" and it's trade names are "Clorox" or "Purex". Scheele, a Swedish chemist, is generally credited with discovering chlorine in 1774. Hawkins is a large manufacturer of bleach and has multiple facilities dedicated to manufacturing and distributing high quality bleach. When storing this chemical, three factors must be considered: UV can degrade sodium hypochlorite, so special precautions must be taken to reduce this effect. As a bleaching agent it is usually a 5 percent sodium hypochlorite with a pH of about 11.
