Technical information GPS Safety Summary

Cyanuric chloride

This Product Safety Summary is intended to provide a general overview of the chemical substance in the context of ICCA Global Product Strategy. The information on the summary is basic information and is not intended to provide emergency response information, medical information or treatment information.

Substance name Cyanuric chloride CAS-No. 108-77-0

General statement Because cyanuric chloride is used as an intermediate in the chemical industry under strictly controlled conditions, exposure is very limited. Consumer risk and exposure is very unlikely as cyanuric chloride is manufactured and handled in industrial settings only.

The environmental effects, ecotoxicology and toxicology information available for cyanuric chloride is provided based on studies and/or a reliable evaluation of its hazardous properties.

Cyanuric chloride should not enter surface water, groundwater water and soil. General and substance specific operational conditions and risk management measures are in place preventing exposure to workers and release to the environment.

Uses and application Cyanuric chloride is used as an intermediate for the production of other chemicals in the chemical industry.

Physical/chemical properproperttttiesiesiesies Cyanuric chloride is a white solid with a characteristic stinging odor at standard temperature and pressure. The density is 1,9 g/cm³ which is higher than that of water. It does react with water but not with oxygen. Cyanuric chloride is not classified as flammable, as an oxidizer or as an explosive substance. The substance does not self-ignite.

Health effects Cyanuric chloride is harmful if swallowed one time and fatal if inhaled short- time. Cyanuric chloride is corrosive to the skin and causes irreversible damage to the eyes. It is irritating to the respiratory tract. Cyanuric chloride may cause an allergic skin reaction. Information on exposure related observations in humans prevent a definite classification as respiratory sensitizer. Prolonged dermal exposure to cyanuric chloride in animal studies reveals significant irritation to the skin while prolonged inhalative exposure severely affects the respiratory tract mainly due to local caustic effects. Cyanuric chloride is not considered mutagenic or genotoxic. Limited experimental data show no carcinogenic potential following dietary uptake. Cyanuric chloride does not effect fertility and does not cause teratogenic effects.

Effect Assessment Result

Acute toxicity (oral, dermal and harmful if swallowed. Fatal if inhaled inhalation) Irritation/corrosion corrosive to the skin, causes skin/eye/respiratory tract irreversible damage to the eye, irritating to the respiratory tract Sensitization skin sensitizer, not a respiratory sensitizer Toxicity after repeated exposure severe local effects after prolonged dermal/inhalation inhalative exposure, significant local effects after prolonged dermal exposure Genotoxicity/mutagenicity not mutagenic/not genotoxic Carcinogenicity no evidence for a carcinogenic potential Toxicity for reproduction no effects on fertility/no teratogenic effects

Environmental effects Based on available data for the substance, cyanuric chloride is considered to have a low toxicity to aquatic organisms. The product is not readily biodegradable and it has no potential to bioaccumulate.

Effect Assessment Result Aquatic toxicity essentially not toxic to water organisms

Fate and Behavior Result Biodegradation not readily biodegradable Bioaccumulation potential no bioaccumulation expected PBT/vPvB conclusion not considered to be either PBT or vPvB

Exposure Human health Cyanuric chloride is used as an intermediate in the chemical industry in closed systems under strictly controlled conditions. Worker exposure to this chemical in the manufacturing facilities is low because the process, storage and handling operations are enclosed. Specific operational conditions and risk management measures assure limited workplace exposures. When containers and tanks are cleaned, residues are disposed of as hazardous waste. All workers are trained in the safety measures of handling the substance including using personal protective equipment.

Consumers will not come in contact with cyanuric chloride.

EnvirEnvironmentonment Cyanuric chloride is manufactured and used in the chemical industry in closed systems and therefore no release to the environment is expected. Direct use by consumers is not intended.

Risk management recommendations Cyanuric chloride is transferred and handled in closed systems. Apparatus and pipelines are free from leaks. There is no ventilation to atmosphere. The emissions are minimized by appropriate technical measures.

All personal protective measures (respiratory protection, hand protection, eye protection, skin and body protection) are strictly observed. All work is done by regularly trained personnel. The requirements for disposal are strictly monitored.
