EC number: 266-007-8 | CAS number: 65996-74-9 The oxidized surface of steel produced during reheating, conditioning, hot rolling, and hot forming operations. This substance is usually removed by process waters used for descaling, roll and material cooling, and other purposes. It is subsequently recovered by gravity separation techniques. Composed primarily of high-purity iron oxides. May contain varying amounts of other oxides, elements, and trace compounds.

Guidance on Safe Use
Administrative data
First-aid measures
In case of inhalation: Provide fresh air. Seek medical attention if irritation persists.
In case of skin contact: wash off with water and soap.
In case of eye contact: Rinse immediately carefully and thoroughly with eye-bath or water until free of contaminants. Seek medical attention if irritation persists.
In case of ingestion: Rinse mouth immediately.
Fire-fighting measures
Inflammability: Non-flammable and incombustible
Suitable extinguishing media: water spray and sand
Extinguishing media which must not be used for safety reasons: Use extinguishing media appropriated to close-stored products

Disposal considerations
Disposal considerations Theoretically Mill scale is endless reusable and can be used in the production of steel as a raw material. Waste treatment methods: special methods are not required It is referred to the relevant Community provisions and to the relevant national or regional provisions relating to waste Information on recycling and methods of disposal for industry Oil and/or lubricants can adhere to mill scale during the process of generation. Depending on the nature and the properties of these adherences the necessity of additional measures has to be checked. Information on recycling and methods of disposal for the public Mill scale is not provided for the public use: Not relevant
