A copy of this Instruction is enclosed for your information. On page 16, you will see that OSHA has clarified its prohibition against recapping by hand. OSHA policy is that recapping of needles, in general, is not appropriate.
Used needles are to be placed in sharps disposal containers without recapping.
In certain instances in which recapping is unavoidable, such as the situations you describe, recapping by some method other than the traditional two-handed procedure is permitted. Acceptable methods include the use of self-sheathing needles or other auxiliary devices such as resheathing instruments or forceps. The properly performed one- hand scoop technique may also be used. It is our understanding of the EPA Medical Waste Tracking Act that, in New Jersey, used needles are considered regulated medical waste regardless of the presence of infectious agents. You may wish to contact your local EPA office for further information.
