Fire Extinguishing Agents: Water in large amounts (USCG, 1999)

Use water in large amounts, foam, dry powder. In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water.

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again.

Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.

Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Keep combustibles (wood, paper, oil, etc.) away from spilled material.

INHALATION: remove victim to fresh air.

General First Aid:

Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Fight fire from protected location or maximum possible distance. Use flooding quantities of water on fire-involved containers. If necessary use water spray to keep fire-exposed containers cool. Avoid use of water on non-involved material wherever possible.

If material involved in fire: Cool all affected containers with flooding quantities of water. Use water in flooding quantities as fog. Apply water from as far a distance as possible. Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.)

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 430, Code for Storage of Liquids and Solid Oxidizers. Separate from combustibles, oxidizables, ammonia, sodium carbonate (soda ash), calcium hypochlorite, hydrogen peroxide.

Protect container against physical damage. Store in a cool, dark room well-ventilated, and keep away from flammable and oxidizable substances. Drums may explode by heating or contact with water. Therefore, place drums on a palette to protect from washing water, drainage, etc. on the floor. Should not be kept long under insufficient ventilation in summer.

Sources of ignition, such as smoking and open flames, are prohibited where trichloroisocyanuric acid is used, handled, or stored in a manner that could create a potential fire or explosion hazard.

Safe Storage of Pesticides. Always store pesticides in their original containers, complete with labels that list ingredients, directions for use, and first aid steps in case of accidental poisoning. Never store pesticides in cabinets with or near food, animal feed, or medical supplies. Do not store pesticides in places where flooding is possible or in places where they might spill or leak into wells, drains, ground water, or surface water.

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.

Keep water away from release. Approach release from upwind. Isolate leaking containers, if this can be done without undue risk. Prompt cleanup and removal is necessary. Shovel into suitable dry container. control runoff and isolate discharged material for proper disposal.

Cover with weak reducing agent such as hypo, bisulfites or ferrous salts. Bisulfites or ferrous salts need additional promoter of some 3M-H2SO4 for rapid reaction. Transfer the slurry (or sludge) into a large container of water and neutralize with soda ash. Drain into the sewer with abundant water.

If a spill occurs, clean it up promptly. Don't wash it away. Instead, sprinkle the spill with sawdust, vermiculite, or kitty litter. Sweep it into a plastic garbage bag, and dispose of it as directed on the pesticide product label.

After Applying a Pesticide, Indoors or Outdoors. To remove pesticide residues, use a bucket to rinse tools or equipment three times, including any containers or utensils that you used when mixing the pesticide. Then pour the rinsewater into the pesticide sprayer and reuse the solution by applying it according to the pesticide product label directions. After applying any pesticide wash your hands and any other parts of your body that may have come in contact with the pesticide..To prevent tracking pesticides inside, remove or rinse your boots or shoes before entering your home. Wash any clothes that have been exposed to a lot of pesticide separately from your regular wash.

SRP: 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.

Add substance into dilute solution of sodium hydroxide or soda ash with stirring gradualy and neutralize that solution with reducing agents such as sodium sulfite and sodium thiosulfate. Adjust pH with sulfuric acid or hydrogen chloride to make neutral solution and dispose.

Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area after clean-up is complete. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters.

Use vast volume of concentrated solution of reducing agent (bisulfites or ferrous salts with 3M-H2SO4 or hypo). Neutralize with soda ash or dilute hydrochloric acid. Drain into the sewer with abundant water.

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 25(SRC), determined from a water solubility of 1.2X10+4 mg/L(2) and a regression-derived equation(3), indicates that trichloroisocyanuric acid is expected to have very high mobility in soil(SRC). Volatilization of trichloroisocyanuric acid from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 6.2X10-11 atm-cu m/mole(SRC), using a fragment constant estimation method(4). Trichloroisocyanuric acid is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 1.6X10-8 mm Hg at 25 °C(SRC), determined from a fragment constant method(5). Biodegradation data for trichloroisocyanuric acid in the terrestrial environment were not available(SRC,2009). However, in the Japanese MITI test, trichloroisocyanuric acid reacted with water to form isocyanuric acid, which is confirmed to be biodegradable(6).

AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 25(SRC), determined from a water solubility of 1.2X10+4 mg/L(2) and a regression-derived equation(3), indicates that trichloroisocyanuric acid is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(4) based upon an estimated Henry's Law constant of 6.2X10-11 atm-cu m/mole(SRC), developed using a fragment constant estimation method(5). According to a classification scheme(6), an estimated BCF of 3.1(SRC), from its water solublity(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Trichloroisocyanuric acid is expected to undergo hydrolysis in the environment since this compound contains functional groups that hydrolyze under environmental conditions(4). Biodegradation data for trichloroisocyanuric acid in the aquatic environment were not available(SRC,2009). However, in the Japanese MITI test, trichloroisocyanuric acid reacted with water to form isocyanuric acid, which is confirmed to be biodegradable(8).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), trichloroisocyanuric acid, which has an estimated vapor pressure of 1.6X10-8 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely in the particulate phase in the ambient atmosphere. Particulate-phase trichloroisocyanuric acid may be removed from the air by wet or dry deposition(SRC). Trichloroisocyanuric acid does not contain chromophores that absorb at wavelengths >290 nm(3) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).

/AQUATIC SPECIES/ The effects of trichloroisocyanuric acid (TCCA) ... on the freshwater alga Chlorella vulgaris were assessed by toxicity bioassays and by the values of biomarkers in phase I and phase II. The biomarkers included growth rate, concentration of chlorophyll a, activities of 7-ethoxyresorufin-O-dealkylases (EROD), glutathione S-transferase (GST), catalase (CAT), and total glutathione (GSH) ... Trichloroisocyanuric acid was a strong growth inhibitor and, at concentrations of greater than 0.80 mg/L, caused 100% inhibition on 24-hr exposure. The 96-hr EC50 of TCCA was 0.313 mg/L ... In TCCA exposure, GST activity was significantly stimulated, and GSH concentration was increased. Catalase activity increased only at TCCA concentrations of greater than 0.12 mg/L, and no change in EROD activity was observed.

/AQUATIC SPECIES/ This paper reports the acute toxicity of three biocides used in the disinfection of cooling towers, tetrakis(hydroxymethyl) phosphonium chloride (THPC), trichloroisocyanuric acid (TCIC), and sodium bromide (NaBr), on Artemia larvae, their effect on the phototactic response of this organism, and the potential of bioaccumulation in this species. The 24-hr median lethal concentration (LC50) values for these biocides with respect to 24-, 48-, and 72-hr-old Artemia, determined by static bioassays, showed the following rank order of toxicity: THPC < TCIC < NaBr. An age-dependent increase in sensitivity was seen for each compound. All three biocides reduced the phototactic response of 24-hr-old Artemia larvae in 24-hr static bioassays; the median inhibitory concentration ratios obtained were 30 to 40 times lower than their respective 24-hr LC50 values. The results suggest that phototaxis bioassays could provide the speed and simplicity required for screening many potential pollutants for harmful effects. The bioconcentration factors obtained for Artemia larvae exposed to 10% LC50 for 168 hr in renewal assays were 93.75, 1.67, and 0.23 for THPC, TCIC, and NaBr, respectively. This shows these biocides pose no bioaccumulation risk in this organism, although the value of 93.75 obtained for THPC is close to the threshold above which such a risk is considered to exist.

The Koc of trichloroisocyanuric acid is estimated as 25(SRC), using a water solubility of 1.20X10+4 mg/L(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that trichloroisocyanuric acid is expected to have very high mobility in soil.

/HUMAN EXPOSURE STUDIES/ Trichloroisocyanuric acid solution (neutralized, 100 mg/L as available chlorine) was tested on 10 individuals by immersion of the entire forearms eight times a day for 7 days and after a 2 wk rest repeated for 7 days. No skin irritation or sensitization was observed.

/SIGNS AND SYMPTOMS/ Human systemic effects by ingestion: ulceration or bleeding from stomach. Toxicity symptoms include emaciation, lethargy, weakness, and delayed death.

/CASE REPORTS/ Two patients were admitted to the hospital emergency room in respiratory distress after an accidental explosion involving chlorinating agents for the swimming pool. The two primary agents involved were calcium hypochlorite and trichloro-s-triazinetrione; both are commonly used chlorinating agents ...The amount of calcium hypochlorite primarily determines the rate of reaction and heat generation. Appropriate emergency action and treatment for chlorine gas is discussed.

/SURVEILLANCE/ Possible health hazards due to worker exposure to chlorinated isocyanurates at Olin Chemical, Lake Charles, Louisiana, were investigated. At the time of the survey about 90 workers were employed in production activities associated with packaging trichloroisocyanuric acid and sodium dichloroisocyanurate. Personal breathing zone sampling and medical interviews were performed. Particulate concentrations ranged from 0.11 to 38 mg/cu m. About 60% of the dust near the packaging areas was within the respirable size range. No OSHA standards for exposure to any chlorinated isocyanurates have been developed. Workers used respirator facepieces with high efficiency particulate filters. All production workers reported one or more work related symptoms. The most common symptoms were eye irritation and cough. 78% of the women interviewed reported problems or changes in their menstrual cycle since beginning work in the packaging area.

Trichloroisocyanuric acid's production and use as an active ingredient in household dry bleaches, dishwashing compounds, scouring powders, detergent sanitizers, commercial laundry bleaches, swimming-pool disinfectant, bactericide, algicide, bleach, and deodorant(1) may result in its release to the environment through various waste streams(SRC).

AEROBIC: Cyanuric acid is ultimately the end product of use of chloroisocyanurates in bleaching, sanitizing, and disinfection applications. Since the N-chloro derivatives are biocidal, biodegradation studies have centered on the residual cyanuric acid, which has been shown to undergo biodegradation under environmental conditions(1). In the Japanese MITI test, trichloroisocyanuric acid reacted with water to form isocyanuric acid, which is confirmed to be biodegradable(2).

Residues of the following chemical substances are exempted from the requirement of a tolerance when used in accordance with good manufacturing practice as ingredients in an antimicrobial pesticide formulation, provided that the substance is applied on a semi-permanent or permanent food-contact surface (other than being applied on food packaging) with adequate draining before contact with food. ... (c) The following chemical substances when used as ingredients in an antimicrobial pesticide formulation may be applied to: Food-processing equipment and utensils. 1,3,5-Triazine-2,4,6(1H,3H,5H)-trione, 1,3,5-trichloro- is included on this list. Limit: When ready for use, the end-use concentration of all di- or trichloroisocyanuric acid chemicals in the solution is not to exceed 100 ppm determined as total available chlorine.

The Agency has sufficient information on the health effects of the chlorinated isocyanurates and on their potential for causing adverse effects in fish and wildlife and the environment for all uses registered for these chemicals. The Agency therefore concludes that products containing the chlorinated isocyanurates for these uses are eligible for reregistration. Only product chemistry data on certain manufacturing use products are still needed. The Agency has determined that the chlorinated isocyanurate products, labeled and used as specified in this Reregistration Eligibility Document, will not pose unreasonable risks or adverse effects to humans or the environment.

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their continued use. Under this pesticide reregistration program, EPA examines newer health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether the use of the pesticide does not pose unreasonable risk in accordance to newer saftey standards, such as those described in the Food Quality Protection Act of 1996. Sodium dichloroisocyanurate is found on List A, which contains most pesticides that are used on foods and, hence, have a high potential for human exposure. List A consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA '88. Case No: 0569; Pesticide type: antimicrobial; Registration Standard Date: 5/20/88 PB88-220660; Case Status: RED Approved 09/02; OPP has made a decision that some/all uses of the pesticide are eligible for reregistration, as reflected in a Reregistration Eligibility Decision (RED) document .; Active ingredient (AI): trichloroisocyanuric acid; AI Status: OPP has completed a Reregistration Eligibility Decision (RED) for the case/AI.

Both s-triazine-2,4,6(1H,3H,5H)-trione, 1,3,5-trichloro- and s-triazine-2,4,6(1H,3H,5H)-trione, 1,3-dichloro-, sodium salt are unstable in the body (particularly the stomach) because the available chlorine is rapidly reduced. Cyanuric acid (or its monosodium salt) is the degradation product from both products.
