Sharp object safety
Discard sharp can lids safely
Control the sharp lid immediately after opening, wrap it, and place it in a puncture-resistant container.
Last reviewed: 2026-10-12
Why it matters
A loose lid can cut anyone handling rubbish and pierce a rubbish bag.
Wrong action
Leaving the sharp lid exposed or dropping it directly into a plastic bag.
Correct action
Use tongs to control the lid, fully cover the sharp edge with thick card or place it in a puncture-resistant rigid lidded container, then secure it for the household's disposal arrangement. Do not flatten the sharp edge or compress rubbish by hand.
What to do
- Prepare tongs and a closable puncture-resistant container and keep children away.
- Use tongs to place the lid in the container without touching its sharp edge; if wrapping instead, fully cover the edge with thick card and secure it.
- Close the container or confirm the wrapping is secure, then follow the household disposal arrangement; never compress rubbish by hand.
If something happens
For severe bleeding, apply continuous direct pressure with a clean cloth and call 999; do not touch the sharp object with bare hands.
