Exposure controls / personal protection
As the use of adequate technical equipment must always take priority over personal protective equipment, make sure that the workplace is well aired through effective local aspiration.
If the product may or must come into contact or react with water, suitable technical and/or organisational measures should be taken to prevent the development of toxic and/or inflammable gases.
Wear suitable PPE: category I professional long-sleeved overalls and safety footwear (see Regulation 2016/425 and standard EN ISO 20344), protect the hands with type C gloves (see standard EN 374); wear airtight protective goggles (see standard EN 166); wear respiratory protective equipment.
Stability and reactivity
Avoid overheating. Do not allow contact with water. Prevent moisture or water from penetrating inside the containers.
Disposal considerations
Keep contaminated materials in a dry place and protect them from moisture.
Dispose of contents/container in accordance with national regulations.
