Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Guidance on Safe Use
Administrative data
First-aid measures
Inhalation: If symptoms such as nose or throat irritation are observed, remove to fresh air.
Eye contact: Rinse immediately with plenty of clean water or sterile saline solution for at least 15 minutes. Obtain medical attention.
Skin contact: Flush skin with water. Remove contaminated clothing. Obtain medical attention if irritation persists.
Ingestion: Because of its alkalinity, superficial effects of the mouth and oesophagus should be monitored. Obtain medical attention if irritation is observed.
Note to physicians: Treat as a moderately strong alkali exposure. For ingestion of large amounts (> 8 grams), maintain adequate kidney function and force fluids.
Fire-fighting measures
Sodium metaborate 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.
Accidental release measures
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.
Handling and storage
Avoid contact with skin and clothing and wash thoroughly after handling. Good housekeeping procedures should be followed to minimise dust generation. Dry, indoor storage is recommended.

Exposure controls / personal protection
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).
Eye protection: Eye protection according to CEN166:1996 is required.
Hand protection: Wear gloves if environment is excessively dusty. Suitable material: rubber, nitrile, butyl.
Stability and reactivity
Stability: Sodium metaborate is stable under normal conditions of use, storage and transport.
Possibility of hazardous reactions: Avoid contact with strong acids. Material is alkaline and can cause corrosion of metals such as aluminium, tin and zinc. 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.
Disposal considerations
Dispose via a licensed waste disposal contractor. Tonnage quantities of product are not recommended to be sent to landfills.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
