Hypochlorite bleach solution

Vesicants that have entered the body are metabolized, hydrolyzed, or bound to tissue and pose little threat of off-gassing. To remove agents on the outside of the body, wash the remains with a 2% sodium hypochlorite bleach solution (i.e., 2 gallons of water for... 

Contaminated objects or surfaces should be cleaned with 0.1% hypochlorite bleach solution if they cannot be avoided for the hours to days required for natural degradation... 

One company which purchases 3,3 -dichlorobenzidine as the dihydrochloride salt in sealed fiber in drums rinses the empty drums with water, adds the rinse water to the product stream, then sprays the drums with a sodium hypochlorite bleach solution (converting the 3,3 -dichlorobenzidine to a quinone-type compound), and places them in polyethylene bags for disposal (London and Boiano 1986). 

When all assessments are complete, euthanize larvae by immersion in a 0.3 mg/mL solution of Tricaine (15). An alternative method of euthanasia for fish larvae of 4-7 dpf is immersion in a 1.2% sodium hypochlorite (bleach) solution (16). Leave the larvae in euthanasia agent for at least 10 min. 

Caution. Chalcogenophenols have an unpleasant odor and are toxic. H2S, H2Se, or H2Te may be liberated on treatment with acid or exposure to the open air. These compounds should therefore be handled under inert gas in a well-ventilated hood. Contaminated glassware should be treated with sodium hypochlorite (bleach) solution for several hours and rinsed thoroughly with water and acetone before removal from the fume hood. Mercury and mercury salts are highly toxic, and skin and eye contact must be avoided. Mercury residues should be disposed of as toxic heavy metal waste. 

Chlorine sulfite can be used to detect syringyl lignin. The specimen is placed above a tissue soaked in a sodium hypochlorite ( bleach ) solution for 30 minutes. A 3% (w/v) solution of sodium sulfite (Na2S03) is applied to the specimen for 5-10 minutes. Lignin will stain orange to red. 

The reaction of chloro- or bromohydrins with bases provides an economical route for the preparation of epoxides. Halohydrins are readily accessible by treatment of an alkene with either hypochlorous acid (Clj -1- H2O —> HOCl), hypochlorite bleach solution (NaOCl), or hypobromous acid (NBS -1- HjO HOBr). These reactions involve the... 

Hypochlorites Sodium hypochlorite (bleaching solution) is utilized for the bleaching and decolorization of pulp and textiles, for disinfection, e.g. in swimming baths, and for the manufacture of hydrazine (Section 1.4.2). 

Atmospheric conditions and particle size determine the persistence of aerosolized toxin in the environment. Temperature and humidity extremes facilitate toxin degradation, and smaller particles dissipate more quickly into the atmosphere. Studies estimate that aerosolized toxin would decay between less than 1 and 4% per minute. At a 1% decay rate, insubstantial amounts of toxin would remain after 2 days (36). Although botulinum toxin can penetrate mucosal surfaces, it cannot penetrate intact skin. If a release were recognized or announced, and authorities anticipated potential airborne exposure, people could protect themselves by covering their mouths and noses with clothing, such as underwear, shirts, scarfs, or handkerchiefs. In addition, after exposure, washing with soap and water would decontaminate clothing, and a 0.1% hypochlorite bleach solution would be effective on contaminated objects and surfaces (36). 

It is likely that new claims are on the horizon for bleach mold cleaner as a study has found that (hypochlorite) bleach solutions neutralize indoor mold allergens [350], Hypochlorite bleach would also inactivate many types of protein residues (like those from dust mites) by denaturing the protein. Indoor allergen cleaners were launched and on the market briefly in 1999 to 2000, which were nonbleach formulas (depending instead on benzyl benzoate, an acaricide). These products were recalled and discontinued due to consumer complaints. 

Hypochlorites (OCI ). Hypochlorite bleach solutions are made from NaOCl and, to a lesser extent, Ca(OCl)2. Hypochlorites are used in laundering, as disinfectants, in the bleaching of pulp and textiles, and in the removal of ink from recycled paper. Commercial bleaching solutions are obtained by passing chlorine gas through cold, dilute, aqueous sodium hydroxide, as shown in equation 7. 

Hypochlorite bleaching solutions must not contain heavy metal cations, as these cations (like light or heat) promote the decomposition of HOCl, as shown in equation 11. 

Since the reactant resins can also, to a greater or lesser extent, bind chlorine from hypochlorite bleaching solution, nitrogen-free reactant resins... 

Mildly alkaline solutions of ordinary laundry soaps develop a protective coating on zinc and its alloys. They are satisfactory for both warm and cold applications. Detergent solutions are more corrosive however, the better grades include inhibitors, which reduce corrosion to allow reasonably satisfactory service for zinc alloys. Strong alkalies (e.g., hypochlorite bleach solutions) or acid solutions (e.g., Harpic, which contains trisodium hydrogen disulfate) are to be avoided. 

As a rough approximation a solution of 10% NaOCl stored at 15-20 C would be expected to lose 0.5-1% available chlorine in a period of a month, assuming a pH above 11.5. If, however, the solution is stored at higher temperatures the av. CI2 of the solution may fall to 5% in one month. Consequently hypochlorite bleach solution is much more stable at low temperatures. The rate of decomposition may double for each increase in temperature of 5°C, a factor that makes cold storage desirable. 

Promising research is being conducted in animals for ricin antisera and vaccination. If exposure is suspected, decontamination of the area or exposed skin should be done with soap and water or with a 0.1% sodium hypochlorite bleach solution. A protective mask is effective against aerosol exposure. Standard safety precautions should be followed by all health care workers if exposure is suspected. Because of ricin s extreme ease of production, wide availabiUty, and the fact that it is one of the most potent plant toxins known, it is considered to be a potential agent that could be used for bioterrorism.

After skin contact with nerve agents, in their liquid states, ensure that the patient has been undressed and adequately decontaminated in the field with copious amounts of water and a mild liquid detergent, or a dilute 0.5 % sodium hypochlorite (bleach) solution, for at least 15 min. 

Abrin is a fairly stable substance and lasts for a long time in the environment despite extreme conditions such as very hot or very cold temperatures. Like ricin, it is inactivated by hypochlorite (bleach) solutions.
