Following skin contact
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
Following eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Following ingestion
Rinse mouth. Do NOT induce vomiting. Refer for medical attention .
4.2 Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]: TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air may release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist respirations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Activated charcoal is not effective . Do not attempt to neutralize because of exothermic reaction. Cover skin burns with dry, sterile dressings after decontamination . Organic acids and related compounds
SECTION 5: Fire-fighting measures
5.1 Suitable extinguishing media
If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog.
5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. For UN1796, UN1826, UN2031 at high concentrations and for UN2032, these may act as oxidizers, also consult ERG Guide 140. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Substance may react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. (ERG, 2016)
5.3 Special protective actions for fire-fighters
NO water. NO hydrous agents. In case of fire in the surroundings, use appropriate extinguishing media.
SECTION 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
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.
6.2 Environmental precautions
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.

SECTION 10: Stability and reactivity
10.1 Reactivity
Decomposes on heating. This produces toxic and corrosive gases. Reacts violently with water. This produces cyanuric acid, hydrochloric acid and heat. Reacts with methanol, dimethylformamide, dimethyl sulfoxide and 2-ethoxyethanol.
10.2 Chemical stability
no data available
10.3 Possibility of hazardous reactions
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).
10.4 Conditions to avoid

SECTION 12: Ecological information
12.1 Toxicity
- Toxicity to fish: LC50 - Poecilia reticulata - > 1 000 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 1 000 mg/L - 48 h.
- Toxicity to algae: EC50 - Selenastrum capricornuium - 620 mg/L - 72 h.
- Toxicity to microorganisms: NOEC - activated sludge - 576 mg/L - 5 d.
12.2 Persistence and degradability
ANAEROBIC: Complete anaerobic degradation of 250-500 uM cyanuric chloride solutions incorporated into a methanogenic aquifer slurry was observed after a one year time period(1).
12.3 Bioaccumulative potential
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.
12.4 Mobility in soil
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).
12.5 Other adverse effects
no data available
SECTION 13: Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill.
