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 |
| Chromium | 0,5 mg//m3 | NGV (Total) |
| Aluminum |
2 mg/m3 |
NGV (Respirable) |
NGV= Level Limit Value, sanitary limit value for exposure during one working day.
Exposure controls

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.
Chromium
Prolonged contact with chromium compounds or with materials containing chromium can cause allergic reactions. Based on research, it is believed that this only occurs with contact with chromium (VI). Allergic skin reactions are particularly common in work places where work involves the handling of chromates, dichromates and chromic acid fumes, but chromium allergies have also been observed in housewives, cement workers, furriers and joiners (National Chemicals Inspectorate, Sweden, 1995). One type of contact eczema, ‘cement eczema’, is thought to be caused by chromium (VI) in cement.
People who have developed chromium allergies also tend to be hypersensitive to other metals, mainly nickel and cobalt (National Chemicals Inspectorate, Sweden, 1995).
