2. Hazards identification

2.1. Classification of the mixture

Many stainless steels contain nickel as an essential alloying element. Nickel is classified in EC Directive 67/548/EEC as a suspect carcinogen (category 3 – R40) and as a skin sensitizer (R43).
The classification rules of EC Directive 99/45/EC dictate that any preparations with equal to or more than 1% content of nickel must automatically be classified as suspect carcinogens (R40). Stainless steels do not cause nickel sensitization by prolonged skin contact in humans. Nevertheless, all stainless steels with 1% or more nickel are classified as skin sensitizers.

Table 1 The corresponding classification according to EC regulations EC 1272/2008 Annex VI Table 3.1 and EC Directive 67/548/EEC:

Hazard Class and Category Code Hazard statement Code
Carc. 2
Carc. Cat 3, R40
Skin Sens. 1
Resp. Sens. 1 H334 R42/43

*Stainless steels containing more than 10 % Ni are classified as STOT RE1, while stainless steels containing 1-10 % Ni are classified as STOT RE2. Stainless steels containing less than 1 % Ni are not classified.

2.2. Label elements

Since these products are alloys, labelling is not 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. If prolonged skin contact is involved in the processing of this product, please contact the supplier for advice. 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.

4. First aid measures

4.1. Description of first aid measures

There are no specific first aid measures developed for stainless steel. 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.

4.2. Most important symptoms and effects both acute and delayed

No relevant information has been identified.

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

No relevant information has been identified.

5. Firefighting measures

5.1. Extinguishing media

Stainless steels 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.

5.2. Special hazards arising from the mixture

None identified.

5.3. Advice for firefighters

None identified.

6. Accidental release measures

6.1. Personal precautions, protective equipment and emergency procedures

Not applicable.

6.2. Environmental precautions

Not applicable

6.3. Methods and material for containment and cleaning up

Not applicable

6.4 Reference to other sections


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. Exposure controls/personal protection

8.1. Control parameters

There are no occupational exposure limits for stainless steels. Occupational exposure limits apply to some constituent elements (Ni, Cr, Mn, Mo) and certain of their compounds. Table 3 shows limits according to current legislation in Sweden.

Table 3. Occupational Exposure Limits, NGV, (mg/m3 ) IN SWEDEN.
Element and compounds TD RD
Iron oxide, fume as Fe 3,5
Manganese & its inorganic compounds as Mn 0.2 0.1
Chromium as Cr 0.5
Copper and its compounds as Cu 1 0.2
Nickel as Ni 0.5
Molybdenum & its insoluble compounds as Mo 10 5

NGV = Nivågränsvärde (One working day exposure)
RD = Respirable Dust acc. to EN 481; TD = Total 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 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 work place 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 acute toxic.


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


Stainless steels are not corrosive to skin.


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). The requirements of EC regulation EC 1272/2008 Annex VI Table 3.1 are such that alloys with 1% or more of nickel must, by default, also be classified as skin sensitizers.
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.

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.


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.
The requirements of EC regulation EC 1272/2008 Annex VI Table 3.1 are such that all alloys with more than 1% nickel must be classified in the same way as nickel itself, by default.
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.
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.


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.

12.2. Persistence and degradability

Not relevant.

12.3. Bioaccumulative potential

13. Disposal considerations

13.1 Waste treatment methods

Surplus and scrap (waste) stainless steel is valuable commodity 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

Stainless steels containing 1% or more of nickel are classified in the same way as nickel, see section 2. Hazards classification, in this document. However, in recognition of their essentially non-hazardous nature, stainless steels in the massive form are not required to be labelled as hazardous.

15.2. Chemical safety assessment

No chemical safety assessment has been published.
