Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

First-aid measures

Skin contact: Possible burns from molten iron or hot work, if burns occur, flush area for at least 15 minutes under running cold water and seek immediate medical attention.  Cuts from solid edges should be cleaned and treated, if required, seek immediate medical attention

Eye contact: Dust may cause irritation, wash for at least 15 minutes under running cold water.

Inhalation: Effects of inhaling fumes remove to fresh air, if breathing becomes difficult then seek immediate medical attention

Ingestion: Not relevant not a probable route of industrial exposure; however, if ingested obtain medical advice.

Fire-fighting measures

Molten metal may react violently with water. Use extinguishers appropriate for surrounding materials. Avoid having molten iron run onto or trap water under molten iron. Sudden violent release of steam and gases can occur when water is trapped under molten iron.

Fire-Fighting Instructions: Do not release runoff from fire control methods to sewers or waterways.

Fire-Fighting Equipment: Wear a self-contained breathing apparatus (SCBA) with a full facepiece operated in pressure-demand or positive-pressure mode and full protective clothing. Suitable extinguishing media powder, foam, CO2, do not use water

Accidental release measures

Spill/Leak Procedures: Not applicable to iron in solid state.

For spills involving molten iron, personnel should be protected against contact with eyes and skin and avoid inhalation of dust/fume.

Fine, dry material should be removed by vacuuming or wet sweeping methods to prevent spreading of dust. Do not release into sewers or waterways. Collect material in appropriate, labeled containers for recovery or disposal in accordance with local regulations.

Disposal: Any excess product can be recycled for further use, disposed in an appropriately permitted waste landfill, or disposed by other methods, which are in accordance with local regulations.

Handling and storage


The movement of molten iron should be carried out using suitable and approved refractory lined containers. Some products may be secured by straps or bands. These should not be used for lifting as they could cause eye or other injury when tension is released. Certain products, may as a result of processing, be brittle or have residual stress, which might cause fracture or significant movement. All products are likely to have sharp edges, which could cause lacerations, and flying particles may be produced when shearing.

Suitable protective clothing and equipment, such as hand and eye protection should be worn and the systems of work designed to take account of any hazards arising from the risk of fracturing or the release of tension or stress when breaking open banding.


Suitable storage areas should be clearly marked and containers should be sufficient to hold the product.

Exposure controls / personal protection

For molten iron or the generation of airborne particulates, use protective clothing (flame retardant–molten), gloves (aluminized-molten) and safety glasses to prevent skin and eye contact as required. Contact lenses should not be worn where industrial exposures to this material are likely. Wash skin that has been exposed with soap and water or waterless hand cleaner. Suitable protective clothing and equipment, such as cut resistant gloves, and safety spectacles should be worn.  When fume or dust is generated, provide adequate ventilation to ensure that the Occupational Exposure Limits are not exceeded. If necessary provide local fume extraction, with the correct capture hood and capture velocity to match the conditions.

Alternatively, where necessary, suitable respiratory protective equipment should be provided for use by those at risk from inhalation of fumes. A P3 dust mask may be appropriate (to EN 149:2001, FFP3S) as long as this can be proven to form a tight face fit seal on the operators face by achieving a pass during a face fit test.

Stability and reactivity

Solid form:

The product is stable under normal conditions but when subjected to elevated temperatures fumes are produced.

Solid pig iron: avoid contact with acids

Liquid form:

Stability: Molten iron is stable under normal storage and handling conditions.

Chemical Incompatibilities: Encapsulating water with molten iron may cause an explosion.

Conditions to Avoid: Water when iron is in molten state.

Hazardous Decomposition Products: Thermal oxidative decomposition can produce fumes containing oxides of iron and manganese as well as other elements

Disposal considerations

Iron can be recycled to avoid landfill.
