EC number: 215-125-8
CAS number: 1303-86-2
Inhalation: If symptoms such as nose or throat irritation are observed, remove to fresh air.
Eye contact: Use eye wash fountain or fresh water to cleanse eye. If irritation persists for more than 30 minutes, seek medical attention.
Ingestion: Swallowing small quantities (one teaspoon) will cause no harm to healthy adults. If larger amounts are swallowed, give two glasses of water to drink and seek medical attention.
Note to physicians: Observation only is required for adult ingestion of less than 3-4 grams of diboron trioxide. For ingestion in excess of 3-4 grams, maintain adequate kidney function and force fluids.
Diboron trioxide is not flammable, combustible or explosive. The substance is a flame retardant. Use extinguishing media that are appropriate to local circumstances and the surrounding environment.
Avoid contamination of water bodies during clean up and disposal.
Land spill: Vacuum, shovel or sweep up and place in containers for disposal in accordance with applicable local regulations.
Water spill: Remove any intact containers from the water. Advise local water authority that none of the affected water should be used for irrigation or for the abstraction of potable water until natural dilution returns the boron level to its normal environmental background level.
No special handling precautions are required. Good housekeeping procedures should be followed to minimise dust generation. Dry, indoor storage is recommended.
Occupational exposure controls: Ensure adequate ventilation. Use local exhaust ventilation to keep airborne concentrations of dust below permissible exposure limits.
Respiratory protection: Where airborne concentrations are expected to exceed exposure limits, respirators should be used (CEN149).
Hand protection: Wear gloves if environment is excessively dusty. Suitable material: rubber, nitrile, butyl.
Stability: Boric acid is stable under normal conditions of use, storage and transport.
Possibility of hazardous reactions: Reaction with strong reducing agents such as metal hydrides or alkali metals will generate hydrogen gas which could create an explosive hazard.
Hazardous decomposition products: None.
Dispose via a licensed waste disposal contractor. Tonnage quantities of product are not recommended to be sent to landfills.
