Store in a cool, dry, well-ventilated location. Outside or detached storage is preferred. Must be stored in a dry location on pallets arranged according to NFPA 43A, Code for Storage of Liquid and Solid Oxidizers. Separate from combustible, oxidizing materials, ammonia, sodium carbonate (soda ash), calcium hypochlorite, hydrogen peroxide.

Chlorine-like

The solid may vigorously react with water releasing chlorine gas. Material containing less than 39% available chlorine will undergo reactions as described herein, but may take longer to initiate, and the resulting reaction may not be as vigorous. Water soluble.

Salts, Acidic

Strong Oxidizing Agent

Contact with ammonium compounds or hydrated salts can cause a very vigorous reaction. Prolonged exposure to heat /fire may result in the vigorous decomposition of the material with the rupture of its containers, it will accelerate the burning of combustible materials. Chlorine plus alcohols would yield alkyl hypochlorites. They decompose in the cold and explode on exposure to sunlight or heat. Tertiary hypochlorites are less unstable than secondary or primary hypochlorites [NFPA 491 M. 1991].

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.

Contact with foreign materials, organic matter, or easily chlorinated or oxidized material may result in fire. Mixture with ammonium salts or similar nitrogen containing compounds may result in exothermic reactions, causing fire or explosion. Reacts with water to release chlorine gas and nitrogen trichloride and in confined spaces increased temperature and pressure to dangerous levels.

Special Hazards of Combustion Products: May form toxic chlorine and other gases in fire Behavior in Fire: Decomposition can be initiated with a heat source and can propagate throughout the mass with the evolution of dense fumes. Containers may explode when heated. (USCG, 1999)|Reactive - 2nd degree

Excerpt from ERG Guide 140 [Oxidizers]: 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. LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet). 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. (ERG, 2016)

Excerpt from ERG Guide 140 [Oxidizers]: Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Do not get water inside containers. SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area. SMALL LIQUID SPILL: Use a non-combustible material like vermiculite or sand to soak up the product and place into a container for later disposal. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Following product recovery, flush area with water. (ERG, 2016)

The material itself is noncombustible but if contaminated with a combustible material ignition can result. It will accelerate the burning of combustible materials. /Dichloroisocyanuric acid, dry or salts/

If material on fire or involved in fire: Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. /Dichloroisocyanuric acid, dry or salts/|If fire becomes uncontrollable - consider evacuation of one-half (1/2) mile radius. /Dichloroisocyanuric acid, dry or salts/|Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Fight fire from protected location or maximum possible distance. Use remote equipment whenever possible. Use flooding quantities of water or fire-involved containers. If necessary use water spray to keep fire-exposed containers cool.

Keep water away from release. Approach release from upwind. Isolate leaking containers, if this can be done without undue risk. Prompt cleanup and removal are necessary. Do not create dust. Shovel into suitable dry container. Control run-off and isolate discharge material for proper disposal.

If material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. /Dichloroisocyanuric acid, dry or salts/|Personnel protection: .. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. ... If contact with the material is anticipated, wear appropriate chemical protective clothing. Approach fire with caution. /Dichloroisocyanuric acid, dry or salts/|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.

Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues. (See all compounds classified as Antifungal Agents.)|Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly. (See all compounds classified as Antiviral Agents.)|Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed) (See all compounds classified as Disinfectants.)

Dust causes sneezing and coughing; is moderately irritating to the eyes and causes itching and redness of skin. Ingestion causes burns of mouth and stomach. (USCG, 1999)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. (NTP, 1992)

The toxicity is apparently due to corrosive action on stomach lining rather than to any systemic effects. In the presence of moisture, as in the eyes, upper respiratory tract or on moist or abraded skin, it is moderately irritating. In some individuals bronchospasm may result from breathing the dust. /Trichloroisocyanuric acid/
