Health & Safety & Disposal

When handling powdered ceramic materials, you must wear an FFP3/P2 face mask and nitrile gloves to prevent inhalation and skin contact.
Wear a wipeable apron, polyester overalls, or similar. Clean or wash frequently.
Always clean your studio with a wet sponge rather than sweeping to stop dust from becoming airborne.
When preparing glazes, add the dry material to water, not vice-versa, to minimise dust formation.
Do not allow eating and drinking in the studio and thoroughly wash hands when leaving.
Never eat, drink, or apply cosmetics in areas where clay or glazes are handled.
Ensure emergency eye-washing facilities are available in the room.
Review official guidelines regarding studio ventilation and chemical management routinely.

Alumina hydrate is not classified as hazardous under UK or EU classification systems. However any airborne dust is treated as a hazard.

Dispose of as normal industrial waste, in accordance with local/regional/national/international regulations.
