ABSTRACT:
A hypodermic syringe needle destroying apparatus and method using electrical resistance heating between electrodes which are convergent either geometrically or by virtue of relative movement to conduct incinerating currents first throughout the entire length of the contaminated needle and thereafter over progressively shorter lengths until the entire needle is destroyed. Any remaining needle stub can be removed or deformed while in its heated state by impacting it against a deforming barrier.
