Handling and storage
7.1 Precautions for safe handling
Advice on safe handling : Avoid dust formation. Ensure adequate ventilation and, if necessary, exhaust ventilation when handling or transferring the product. Ensure that the occupational exposure limit value/s (OEL) and/or other limit values are complied with.
Advice on protection against fire and explosion: Keep away from open flames, hot surfaces and sources of ignition.
Take precautionary measures against static discharges. During processing, dust may form explosive mixture in air.
Hygiene measures : Handle in accordance with good industrial hygiene and safety practice. Keep working clothes separately.
Dust explosion class : St1
7.2 Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers: No special requirements required.
Further information on storage conditions: Store in tightly closed containers in a dry place.

Exposure controls / personal protection
Prevent formation of dust. Where required to control exposure, provide local exhaust ventilation.
It is known that high temperature processes including production and welding of chromium and chromium-containing composites can lead to generation of fumes containing chromium(VI). Although the precise identity of the chromium(VI) substances present has not been identified, it is important to recognize that several substances containing chromium(VI) have been classified as carcinogenic, mutagenic, toxic for reproduction and dangerous for the environment. It is therefore essential that workplaces and releases to the environment associated with these activities are monitored to ensure compliance with national and/or Community legislative limits.
Regarding this issue, the users are referred to follow recommendations presented in the paper 'REACH and the Welding of Metals and Alloys', published by Eurometaux, Eurofer and European Welding Association (May 2010).
Personal protection
General protective and hygienic measures: Practice good hygiene. Keep away from food and drink.
Skin and body protection: Avoid contact with eyes and skin. Use anti-static safety shoes and protective suit.
Respiratory protection: Adequate protection measures must be used to maintain exposure levels below stated
limits. Respiratory protective device with particle filter EN 143.
Protection of hands: Gloves should be worn when handling this material because of the risk of contact with
sharp particles
Eye protection: Wear suitable eye protection (e.g. safety glasses) during handling in which dust is formed.
Risk management measures: Where practical exposure levels should be controlled using extraction systems. It may be necessary to undertake a programme of exposure monitoring.
Environmental exposure control
Although no special environmental precautions requried, do not wash spilled materials into drainage system, material may block drains.
Stability and reactivity
Thermal decomposition / conditions to be avoided: Stable under normal conditions. No decomposition if used according to specifications.
Dangerous reactions : Reacts with oxidizing agents.
Fumes containing hexavalent chromium may be formed during high temperature processes (production and
welding). Regarding this issue, the users are referred to the paper 'REACH and the Welding of Metals and
Alloys', published by Eurometaux, Eurofer and European Welding Association (May 2010).
Disposal considerations
Disposal of waste should be undertaken by a licensed contractor in accordance with appropriate national and
local regulations.
