2.1. Classification of the mixture
No hazards of the mixture according to EC 1272/2008 regulation.
2.2. Label elements
No labelling is required.
2.3. Other hazards
There are no hazards of concern for man or the environment from stainless steels in the forms supplied. However, if an individual is already sensitized to nickel, prolonged skin contact with a few types of stainless steel may result in an allergic dermatological reaction. No carcinogenic effects resulting from exposure to stainless steels have been reported, either in epidemiological studies or in tests with animals.
Dust and fume may be generated during processing e.g. in welding, cutting and grinding. If airborne concentrations of dust and fume are excessive, inhalation over long periods may affect workers' health, primarily of the lungs.

7. Handling and storage
7.1. Precautions for safe handling
There are no special technical measures involved for handling stainless steels. 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.

8.2. 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 fume 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 assure that environmental legislation is fulfilled.

11. Toxicological information
11.1. Information on toxicological effects
Acute toxicity
Stainless steels are not acutely toxic.
Irritation
The exposure route of concern is inhalation. These stainless-steel products are in massive form, not capable of being inhaled.
Corrosivity
Stainless steels are not corrosive to skin.
Sensitization
Nickel is classified as a skin sensitizer. It causes skin sensitization in susceptible individuals through prolonged intimate contact with the skin (e.g. wearing of jewelry).
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.
Carcinogenicity
Stainless steels may contain nickel, which has been classified, see section 2, Hazards identification. The exposure route of concern is inhalation. These stainless steel products are in massive form, not capable of being inhaled.
Mutagenicity
Stainless steels are not classified as mutagenic.
Toxicity for reproduction
Stainless steels are not toxic for reproduction.
12. Ecological information
12.1. Toxicity.
Not ecotoxic.

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
Nickel alloy products 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.
Comments
There is no direct evidence of carcinogenic effects of nickel alloys in man, nor indirect evidence from animals tested by relevant routes, i.e. inhalation or ingestion. In other studies, using non-relevant routes in animals, alloys with up to 40 % nickel caused no significant increase in cancer. Studies of workers exposed to nickel powder and dust and fumes generated in the production of nickel alloys and stainless steels have not indicated a respiratory cancer hazard.
Numerous patch tests have established that most stainless steels do not cause sensitization. However, studies have shown that in some individuals already sensitized to nickel, close and prolonged skin contact with the re-sulphurised free-machining types of stainless steel with 0,15 – 0,35 % S (EN 1.4105, 1.4523, 1.4305, 1.4570) may cause an allergic reaction. The uses of products that contain Ni and which come into direct and prolonged contact with the skin are limited by 2004/96/EC. Posts inserted into pierced ears and other parts of the body during epithelization of the wound must not contain more than 0,050 % Ni. Other Ni-containing products in direct and prolonged contact with the skin must release no more than 0,5 mg/cm2/week of Ni as defined in EN 1811.
Welding and flame cutting fumes may contain hexavalent chromium compounds.
Studies have shown that some hexavalent chromium compounds can cause cancer. However, epidemiological studies amongst welders indicate no extra increased risk of cancer when welding stainless steels, compared with the slightly increased risk when welding steels that do not contain chromium. The UK Health & Safety Executive´s publication "Control of fume arising from electric arc welding of stainless steel" indicates that there is some risk of developing asthma from compounds of chromium VI and nickel in the fume from stainless steel welding. However, stainless steel welding fume did not meet the European Union classification criteria required for a substance capable of causing asthma.
