Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: remove patient from exposure and bring to fresh air. If breathing has stopped, perform artificial respiration and get medical advice/attention immediately.
Skin contact: wash skin with water and soap, and rinse thoroughly. If skin irritation occurs, get medical advice/attention.
Eye contact: check for and remove any contact lenses. Immediately flush eyes with plenty of water, occasionally lifting upper and lower eyelids, for several minutes. Get medical advice/attention.
Ingestion: Seek medical advice/attention. If vomiting occurs, keep head lower than hips to prevent aspiration.
Fire-fighting measures
Fire and explosion hazard: Negligible fire hazard when exposed to heat or flame.
Extinguishing media: Dry chemical, carbon dioxide, water spray or regular foam. For larger fires use water spray, fog or regular foam.
Firefighting: Move container from fire area if you can do it without risk. Apply cooling water to sides of container that are exposed to flames until well after the fire is out. Extinguish using agent indicated: do not use water stream directly on material. If larger amounts of combustible materials are involved, use water spray or fog in flooding amounts. Avoid breathing corrosive dust and fumes burning material, keep upwind.
Hazards Combustion Products: Thermal decomposition may release toxic and/or hazardous gases.
Accidental release measures
Occupational spill: Stop leak if you can do it without risk. For small spills, take up sand and or other absorbent material and place into containers for later disposal. For small dry spills, vacuum or shovel material into clean, dry container and cover. For larger spills, dike ahead of spill for later disposal.
Handling and storage
Storage: Avoid formation of dust. Observe national and regional provisions in force. Store away from incompatible substances ( Bromine Pentafluoride: violent reaction which may ignite, Chlorine Trifluoride: violent reaction that may ignite, Lithium: reacts, Magnesium: when heated a violent detonation may occur, Potassium: reacts with incandescence , Sodium: reacts violently).

Exposure controls / personal protection
No specific measures are needed other than good hygiene practice and adherence to national and regional provisions with regards to exposure to dusts in the workplace and with regard to air emissions. Conditions and work practices that generate dust should be avoided or controlled. Diffuse emissions can be minimised for example by damping down dust with water spray.
The existing available data indicates that there are no adverse effects at exposure levels up to the general dust limits of 3 mg/m3 respirable fraction. Nevertheless, adherence to these levels should be ensured to avoid any risk.
Stability and reactivity
Stable under ambient temperatures and pressures.
According to “Bretherick’s Handbook” molybdates react violently or explosively when reduced to molybdenum by heating with zirconium (Bretherick’s Handbook of Reactive Chemical Hazards. 7th Edition, Elsevier Acedemic Press, 2007). Other hazardous reactions have not been identified. No specific conditions to avoid have been identified. No specific incompatible materials have been identified. No hazardous decompositions products have been identified.
Disposal considerations
Waste (substance and container material) shall be recycled/recovered or disposed of as applicable and in accordance with community (EU) and local legislation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
