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.
SPILL: Increase the immediate precautionary measure distance, in the downwind direction, as necessary.
FIRE: If tank, rail tank car or highway tank 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, 2024)
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.
· For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances.
· For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary.
· If tank, rail tank car or highway tank 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.
Sweep spilled substance into covered sealable containers. Carefully collect remainder. Then store and dispose of according to local regulations. Personal protection: complete protective clothing including self-contained breathing apparatus.
CYANURIC CHLORIDE WAS PARTIALLY (50%) HYDROLYZED TO CYANURIC ACID BY TREATMENT WITH SODIUM HYDROXIDE AT 80 °C. THE SOLN OBTAINED WAS TREATED WITH SODIUM OXYCHLORIDE AT PH 9-10 & AT 50 & 70 °C. USING 5.5 MOL OF ACTIVE CL/MOL OF CYANURIC CHLORDE, 99% OF CYANURIC CHLORIDE WAS DECOMP ACCORDING TO THE EQUATION. THE REACTION TIME AT 50 & 70 °C WERE 40 & 15 MIN.
Sweep spilled substance into sealable containers. Carefully collect remainder, then remove to safe place.
Environmental considerations - and spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete.
Environmental considerations - water spill: Use natural barriers or oil spill control booms to limit spill travel. Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. Remove trapped material with suction hoses.
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
THE BASIC VENTILATION METHODS ARE LOCAL EXHAUST VENTILATION AND DILUTION OR GENERAL VENTILATION.
...SUBSTITUTION OF LESS IRRITATING SUBSTANCES...REDESIGN OF OPERATIONS...PREVENT CONTACT, PROVISION OF A PHYSICAL BARRIER AGAINST CONTACT, PROPER WASHING FACILITIES, WORK CLOTHING AND STORAGE FACILITIES, PROTECTIVE CLOTHING, AND BARRIER CREAMS. MEDICAL CONTROL...
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.
Personnel protection: Avoid breathing dusts, and fumes from burning material. Avoid bodily contact with the material. ... If contact with the material anticipated, wear appropriate chemical protective clothing.
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.

Water-Reactive
CYANURIC CHLORIDE reacts rapidly and exothermically with water to generate hydrogen chloride. A mixture with water in an industrial reactor with refrigeration turned off developed pressure that blew gaskets and filled the building with flammable vapors. An explosion occurred when the vapors were ignited [MCA Case History 1869(1972)]. Runaway reactions have occurred with acetone/water; methanol/water, ethoxyethanol/water, allyl alcohol/sodium hydroxide/water, 2-butanone/sodium hydroxide/water, and methanol/sodium bicarbonate [Loss Prev. Bull., 1979, (25), 21]. Reacts with methanol to give gaseous methyl chloride. Reacts rapidly with bicarbonates to generate gaseous carbon dioxide. Reacts vigorously with dimethyl formamide (DMF) to form carbon dioxide after a deceptive induction period [BCISC Quart. Safety Summ., 1960, 35, 24]. Can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air).
Reacts violently with water producing cyanuric acid, hydrochloric acid and heat. Reacts with methanol, dimethylformamide, dimethyl sulfoxide and 2-ethoxyethanol.
Cyanuric chloride reacts vigorously and exothermically with dimethylformamide after a deceptively long induction period. The 1:1 adduct initially formed decomposes above 60 °C with evolution of carbon dioxide and formation of a dimeric unsaturated quarternary ammonium salt.

/HUMAN EXPOSURE STUDIES/ In human volunteers, the 1-min threshold irritation effect of inhaled cyanuric chloride was found to be 0.3 mg/cu m.
/SIGNS AND SYMPTOMS/ ...HAS SEVERE IRRITANT EFFECT ON EYES & RESP PASSAGES, BUT LESS EFFECT ON SKIN. SENSITIVITY & CHRONIC ECZEMA HAVE BEEN OBSERVED.
/CASE REPORTS/ Cyanuric chloride is a lachrymator and an irritant to the eyes and nose. Exposure of a laboratory assistant to a small amount of vapor resulted in rash on the neck and behind the ears with irritation.
/CASE REPORTS/ An, in general, healthy male (age 54) was exposed to cyanuric chloride during an inspection in a factory where herbicides were produced. Cyanuric chloride (one of the basic materials) was accidentally released, because a vessel got broken. The man was totally submerged under the powder. Signs of intoxication consisted of irritation of the skin, eyes and pharynx, followed by serious obstructive pulmonary syndrome with impairment of alveolar capillary exchanges. No effects on the heart function were seen (although a slightly abnormal ECG was reported from an pre-exposure investigation). The man recovered within 20 days.
/BIOMONITORING/ 39 workers with known history of long-term exposure to cyanuric chloride (between 1 and 22 years) were investigated. Investigations included anamnesis, physical examination (with special attention to lungs, skin and eyes), lung function (forced expiratory volume) and blood pressure measurements. Medical records of another 21 workers previously exposed to incidental high concentrations, who had changed jobs in the mean time, were checked. Determination of concentrations at the workplace. Samples (30-60 min) were taken during the filling procedure (worst case) and during normal production procedures (both room and personal monitoring). The samples were analyzed after adsorption tosilicagel, desorption with H2SO4, hydrolysis to cyanuric acid (70 min at 70 °C) and analysis of the cyanuric acid by HPLC with UV detection. No effects on any of the measured parameters were found. FEV was within normal ranges. Accidental acute exposure to high doses of cyanuric chloride was reported to lead to irritation/corrosion of the conjunctiva and skin irritation. After inhalation of the test substance coughing, breathing problems and shortness of breath were seen. These effects disappeared completely after a short time and did not result in persisting problems. Measured concentrations were 7.09 = or - 9.22 ug/cu m, 4.43 = or - 2.72 ug/cu m and 92.76 = or - 147.52 cu m, for filling, room and personal monitoring, respectively.
/LABORATORY ANIMALS: Acute Exposure/ INHALATION STUDIES WITH THE DUST HAVE SHOWN THE 4-HR LC50 IN RATS IS 25 MG/CU M (20.4% RESPIRABLE PARTICLES, LESS THAN 10 UM IN DIAMETER) & 2-HR LC50 IN MICE IS 10 MG/CU M WITH THE THRESHOLD FOR CNS DISTURBANCES BEING 0.6 MG/CU M.
/LABORATORY ANIMALS: Acute Exposure/ Cyanuric chloride was administered by oral gavage to Charles River CD albino rats for 5 days. Dosage levels and mortality data are as follows: 0 (0/5 M, 0/5 F), 10 (0/5 M, 0/5 F), 20 (0/5 M, 0/5 F), 40 (0/5 M, 1/5 F), 80 (2/5 M, 4/5 F), 160 (4/5 M, 4/5 F), and 320 mg/kg/day (5/5 M, 5/5 F). Clinical signs at 20 mg/kg/day included rales, excessive salivation, and/or gasping.

Cyanuric chloride's production and use as a precursor in the synthesis of herbicides and insecticides, optical brighteners, dyes, and plastics may result in its release to the environment through various waste streams. If released to air, an estimated vapor pressure of 0.023 mm Hg at 25 °C indicates cyanuric chloride will exist solely in the vapor phase in the ambient atmosphere. Vapor-phase cyanuric chloride is degraded slowly in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 4,300 days. Cyanuric chloride does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, cyanuric chloride is expected to have high mobility based upon an estimated Koc of 120. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 4.9X10-7 atm-cu m/mole. Volatilization from dry soil surfaces is not expected to be an important fate process given the estimated vapor pressure of cyanuric chloride. If released to water, cyanuric chloride is not expected to adsorb to suspended solids or sediment in the water column based upon the estimated Koc value. Volatilization from water surfaces is not expected to be an important environmental fate process given the estimated Henry's Law constant. Hydrolysis is the dominant environmental fate process for cyanuric chloride. A suspension of cyanuric chloride in ice water was stable for about 12 hours; however, at 30 °C, over 40% hydrolyzed to cyanuric acid within 1 hour. Complete anaerobic degradation of 250-500 uM of cyanuric chloride solutions incorporated into a methanogenic aquifer slurry was observed after a one year time period; however, the likely mechanism of degradation was hydrolytic dehalogenation rather than microbial degradation. An estimated BCF value of 2, as well as the rapid rate of hydrolysis, suggests the potential for bioconcentration in aquatic organisms is low. Occupational exposure may occur through dermal contact with this compound at workplaces where cyanuric chloride is produced or used. (SRC)

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), cyanuric chloride, which has an estimated vapor pressure of 0.023 mm Hg at 25 °C(SRC), determined from a fragment constant estimation method(2), will exist solely as a vapor in the ambient atmosphere.

The rate constant for the vapor-phase reaction of cyanuric chloride with photochemically-produced hydroxyl radicals has been estimated as 3.7X10-15 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 4,300 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1).

An estimated BCF of 2 was calculated in fish for cyanuric chloride(SRC), using an estimated log Kow of 1.73(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF value suggests the potential for bioconcentration in aquatic organisms is low(SRC). Cyanuric chloride hydrolyzes rapidly in water(4), thus eliminating bioconcentration as an important environmental fate property.
Using a structure estimation method based on molecular connectivity indices(1), the Koc for cyanuric chloride is estimated as 120(SRC). According to a classification scheme(2), this estimated Koc value suggests that cyanuric chloride possesses high mobility in soil(SRC).
The Henry's Law constant for cyanuric chloride is estimated as 4.9X10-7 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that cyanuric chloride is not expected to volatilize from water surfaces or moist soil surfaces(2). Moreover, cyanuric chloride hydrolyzes rapidly in water(3), thus eliminating volatilization as an important environmental fate property. Cyanuric chloride is not expected to volatilize from dry soil surfaces(SRC) based upon an estimated vapor pressure of 0.023 mm Hg(SRC), determined from a fragment constant method(4).
