Discard all used uncapped needles and syringes in an impenetrable protective container

According to the Centers for Disease Control (CDC), blood-to-blood contact occurs most commonly when a health care worker attempts to cap a used needle. Therefore, used needles should never be recapped; instead they should be inserted in a specially designed puncture resistant, labeled container. Wearing gloves is not always necessary when administering an I.M. injection. Enteric precautions prevent the transfer of pathogens via feces.
