Apply safe handling practices when using sharps (e.g. needles / scalpels / use of glass Pasteur pipettes (see below)) - do not use them until you have received appropriate training
Never try to force a glass pipette or glass tube into a pipette filler or other orifice: push the filler gently onto the glass tube (not the other way round), holding the pipette as close as possible to the end you are fitting. Wear gloves or use a cloth to further protect your hands in the event of breakage if necessary. Ask for assistance if you are unsure
Safely dispose of all sharps in sharps bins to avoid risk of sharps injury to others
