Safer sharps or needle locking syringe device are used for rDNA

A safer sharp is a non-needle sharp or a needle device with a built-in safety feature or mechanism that effectively reduces the risk of an exposure incident.

Only needle-locking syringes or disposable syringe-needle units (i.e., needle is integral to the syringe) are used for the injection or aspiration of fluids containing organisms that contain recombinant or synthetic nucleic acid molecules.

Laboratories that use human derived materials or work with bloodborne pathogens are subject to the requirements of the Bloodborne Infectious Diseases Standard. This standard requires that available safer sharps devices be used and that those devices be reviewed annually in consideration of newly marketed ones.
