4. First-aid measures

4.1. Description of first aid measures

There are no specific first aid measures developed. Medical attention should be sought in case of an excessive inhalation of dust, a physical injury to the skin or to the eyes.

Note that austenitic stainless steel particles are non-magnetic or only slightly magnetic and may therefore not respond to a magnet placed over the eye.

No relevant information has been identified.

4.3. Indication of any immediate medical attention and special treatment needed

No relevant information has been identified.

Alloys in massive form are not combustible.

However, care should be taken to avoid exposing fine process dust (e.g. from grinding and blasting operations) to high temperatures as it may present a potential fire hazard.

None identified.

5.3. Advice for firefighters

None identified.

6. Accidental release measures

6.1. Personal precautions, protective equipment and emergency procedures

6.4 Reference to other sections


7. Handling and storage

7.1. Precautions for safe handling

There are no special technical measures involved in handling. Normal precautions should be taken to avoid physical injury from coiled or bundled products, possibly with sharp edges:

Straps or bands, used to secure some products, should not be used for lifting. Coils and bundled products (e.g. sections, rods, bars, etc.) may spring apart when the banding is removed and the banding itself could cause eye or other injury when tension is released.

Certain products may, as a result of processing, be brittle or have residual stress that might cause fracture or significant deformation.

All products are likely to have sharp edges that 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 systems of work adopted to take account of any hazards arising from the risk of fracturing or the release of tension when breaking open banding.

Suitable racks should be used to ensure stability when stocking narrow coils.

7.2. Conditions for safe storage, including any incompatibilities

The product is stable in storage. However, it should be kept in mind that the products may display sharp edges and a sufficiently robust place capable of carrying the significant weight of the products should be used for storage.

7.3. Specific end uses

None identified.

8. Exposure controls/personal protection

8.1. Control parameters

Elements TD ID RD
Carbon 3
Manganese and its inorganic compounds as Mn 0.2 0.05
Chromium and its compounds as Cr 0.5
Cobalt and its inorganic compounds as Co 0.02

Table 3 Occupational Exposure Limits, NGV, (mg/m3 ) in Sweden.
NGV = Nivågränsvärde (One working day exposure)
TD = Total Dust
ID = Inhalable Dust
RD = Respirable Dust

8.2. Exposure controls

8.2.1. Appropriate engineering controls

In the processing of all metallic materials, exposure to fume and dust must be kept below any legally imposed limits.
Dust and fumes may be generated in use, e.g. by cutting, grinding and welding processes, which may contain materials subject to exposure limits. To ensure these limits are not exceeded, adequate general or local ventilation or fume extraction should be provided.

8.2.2. Individual protection measures, such as personal protective equipment

In accordance with European and national health and safety regulations, it is necessary to assess the need for personal protection equipment and appropriate approved respiratory protection should be provided for those workers at risk of inhalation. Suitable hand and eye protection should be worn where there is a risk of laceration, flying particles, welding heat radiation or contact with oils during processing.
The process of welding should only be performed by trained workers with the personal protective equipment in accordance with the laws of each member state relating to safety.

8.2.3. Environmental exposure controls

Emissions from ventilation or equipment in the workplace should be controlled in order to ensure that environmental legislation is fulfilled.

11. Toxicological information

11.1. Information on toxicological effects

Acute toxicity

Not acutely toxic.


The exposure route of concern is inhalation. These stainless steel products are in massive form, not capable of being inhaled.


Not corrosive to skin.


Cobalt is classified as a skin sensitizer. It causes skin sensitization in susceptible individuals through prolonged intimate contact with the skin.

Repeated dose toxicity

During mechanical working, flame cutting or welding, dust, or fumes containing complex or mixed oxides (spinels) of its constituents, may be formed. Over long periods, inhalation of excessive airborne levels may have long term health effects, primarily affecting the lungs.


Not classified as carcinogenic.


Not classified as mutagenic.

Toxicity for reproduction

Not toxic for reproduction.

12. Ecological information

12.1. Toxicity.

Not ecotoxic.

12.2. Persistence and degradability

Not relevant.

12.3. Bioaccumulative potential


12.4. Mobility in soil

Not soluble in water. Immobile.

12.5. Results of PBT and vPvB assessment

Not relevant.

12.6. Other adverse effects

13. Disposal considerations

13.1 Waste treatment methods

Surplus and scrap (waste) are valuable commodities and in demand for the production of prime stainless steel.
Recycling routes are well-established, and recycling is, therefore, the preferred disposal route. Disposal to landfill is not harmful to the environment, but is a waste of resources and therefore less desirable than recycling.

14. Transport information

No special precautions required.
The product is not classified as hazardous for transport.

15. Regulatory information

15.1. Safety, health and environmental regulation/legislation specific for the mixture

No specific regulation.

15.2. Chemical safety assessment

No chemical safety assessment has been published.

16. Other information

Food contact materials

The Council of Europe published “Metals and alloys used in food contact materials and articles – A practical guide for manufacturers and regulators, 1st ed 2013” to ensure that metallic materials used in contact with food comply with the regulation EC 1935/2004. The document includes a section on stainless steels.

References to regulations

Alloys are considered as articles under regulation EC 1907/2006, concerning the registration, evaluation, authorization and restriction of chemicals (REACH). In accordance with REACH and regulation EC 1272/2008 on classification, labeling and packaging of substances and mixtures (CLP) only substances and preparations require a safety data sheet (SDS). While articles under REACH do not require a classic SDS but articles shall be accompanied by sufficient information to permit safe use and disposal. In order to comply with this requirement, a safety information sheet (SIS) has been developed.


The information given in this safety information sheet is based on the present level of our knowledge and experience. The data sheet describes the products with respect to safety requirements. The data given is not intended as a confirmation of product properties and does not constitute a legal contractual relationship, nor should it be used as the basis for ordering these products.
