Needle and Sharps Precautions
Needles and syringes or other sharp instruments should be restricted to parenteral injection, phlebotomy, or aspiration of fluids from laboratory animals and diaphragm bottles.
Only needle-locking syringes or disposable syringe-needle units (i.e., needle is integral to the syringe) are used for injection or aspiration of infectious materials.
Syringes which re-sheathe the needle, needleless systems, and other safety devices are used when appropriate.
