4.11 DOT Emergency Guidelines: /GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Health: TOXIC; inhalation, ingestion, or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. /Hypochlorite solution; Hypochlorite solution, with more than 5% available Chlorine/
/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Fire or Explosion: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. /Hypochlorite solution; Hypochlorite solution, with more than 5% available Chlorine/
/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Public Safety: CALL Emergency Response Telephone Number. As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate enclosed areas. /Hypochlorite solution; Hypochlorite solution, with more than 5% available Chlorine/
/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible. /Hypochlorite solution; Hypochlorite solution, with more than 5% available Chlorine/
/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Evacuation: Fire: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. /Hypochlorite solution; Hypochlorite solution, with more than 5% available Chlorine/
/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Fire: Small fires: Dry chemical, CO2 or water spray. Large fires: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire control water for later disposal; do not scatter the material. Fire involving tanks or car/trailer loads: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. /Hypochlorite solution; Hypochlorite solution, with more than 5% available Chlorine/
/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ Spill or Leak: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. /Hypochlorite solution; Hypochlorite solution, with more than 5% available Chlorine/
/GUIDE 154: SUBSTANCES - TOXIC AND/OR CORROSIVE (NON-COMBUSTIBLE)/ First Aid: Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. /Hypochlorite solution; Hypochlorite solution, with more than 5% available Chlorine/

4.12 Exposure Standards and Regulations: Sodium hypochlorite is an indirect food additive for use only as a component of adhesives.

4.13 Reactivities and Incompatibilities: Chlorination of ethyleneimine with sodium hypochlorite gives the explosive compound 1-chloroethyleneimine.
Primary amines and calcium hypochlorite or sodium hypochlorite react to form normal chloroamines, which are explosive.
Hypochlorites react with urea to form nitrogen trichloride which explodes spontaneously in air. /Hypochlorites/
Contact in the drains of an effluent containing the hypochlorite with one containing ammonium salts & acid led to formation of nitrogen trichloride which decomp explosively. Cleaning a brewery tank with an acidified ammonium sulfate cleaning preparation, then sodium hypochlorite soln without intermediate rinsing, led to nitrogen trichloride formation & a violent explosion.
Interaction of ethyleneimine with sodium (or other) hypochlorite gives the explosive N-chloro cmpd.
Removal of formic acid from industrial waste streams with sodium hypochlorite soln becomes explosive at 55 deg C.
Several explosions involving methanol and sodium hypochlorite were attributed to formation of methyl hypochlorite, especially in presence of acids or other esterification catalyst.
Use of sodium hypochlorite soln to destroy acidified benzyl cyanide residues caused a violent explosion, thought to have been due to formation of nitrogen trichloride.
Explosive reaction with formic acid (at 55 deg C); phenylacetonitrile. Reacts to form explosive products with amines; ammonium salts ... ; aziridine; methanol.
Decomposition of sodium hypochlorite takes place within a few seconds with the following salts: ammonium acetate, ammonium carbonate, ammonium nitrate, ammonium oxalate, & ammonium phosphate.

4.14 Other Preventative Measures: If material not involved in fire: Keep material out of water sources and sewers; build dike to contain flow as necessary. /Hypochlorite soln (containing more than 7% available chlorine, by wt)/
Personnel protection: Avoid breathing vapors. Keep upwind. Avoid bodily contact with the material. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amt of water or soap and water. If contact with the material anticipated, wear appropriate chemical protective clothing. /Hypochlorite soln (containing more than 7% available chlorine, by wt)/
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

4.15 Protective Equipment and Clothing: It has a pronounced irritant effect on the skin.
Irritating to skin and eyes. /Monohydrate/

4.16 Disposal Methods: SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
