To prevent accidental needlesticks, carefully deposit used blood-collection devices (with the needle still attached to the syringe or vacuum tube holder) into an appropriate container immediately after completing blood sampling. Do not recap standard (ie, nonsafety) needles prior to disposal unless a container is not immediately available.
