Exposure controls/personal protection
Exposure limit values
Hygiene standards and exposure limits may differ from country to country. Check those currently applying in your country and comply with regulations. Examples of exposure limit applying Sweden are given below:
| Compound | Exposure limit | Type of value |
| Nickel | 0,5 mg/m3 | NGV (Total) |
| Copper | 0,2 mg/m3 1 mg/m3 |
NGV (Respirable) NGV (Total) |
| Manganese | 0,1 mg/m3 0,2 mg/m3 |
NGV (Total) NGV (Respirable) |
| Cobalt | 0,2 mg/m3 0,05 mg/m3 |
NGV (Total) |
NGV= Level Limit Value, sanitary limit value for exposure during one working day.
Exposure controls
Preventive action: Good general ventilation is recommended.
Respiratory protection: Use when necessary.
Hand protection: Protective gloves, avoid skin contact.
Eye protection: Wear safety glasses when tooling.
Skin protection: Wear suitable protective clothing and protective shoes.

Toxicological information
Inhalation: Dust may cause sensitive persons problem with respiration.
Skin contact: May cause contact eczema and allergy when repeatedly skin contact.
Eye contact: Product dust may cause temporary mechanical eye irritation.
Ingestion: Not a normal route of exposure.
Nickel
Nickel is the most commonly occurring contact allergen. According to surveys from the USA, Italy, Denmark, Finland and Sweden, 8-22 % of women and 0.3-3 % of men develop hypersensitivity to nickel (National Chemicals Inspectorate, Sweden, 1995). The main method of exposure is contact with metallic nickel and/or nickel alloys.
Exposure to nickel has been linked to a risk of lung cancer and nasal cancer, but it has not been possible to identify the form in which nickel is carcinogenic.
Ecological information
No data available.
Disposal considerations
Disposal in accordance with all applicable local and national regulations.
Transport information
Road transport (ADR): Not classified as dangerous in the meaning of transport regulations.
