Trolleys used in conjunction with anaesthetic apparatus are often seen to have a small metal chain hanging down and dragging on the floor. The object of this is to prevent the build-up of static electricity on the trolley which might otherwise cause sparking when connection is made between the equipment on the trolley and other metalwork. The sparks may in turn ignite anaesthetic gases or vapours.

The chain is not normally necessary because trolley wheels on anaesthetic equipment are usually made of antistatic (conductive) rubber which performs the same function.
