ABSTRACT:
A remotely operable drum punch for puncturing a drum or container containing hazardous waste, chemicals, or acid consists of a drive which drives a punch head and self-admixing arms for securing the drum punch to the drum. The drive is remotely operable to drive both the self-affixing arms and the punch head so that the drum punch may be secured to the drum from afar. The punch head includes a collar, which may be movable, to form a seal with the top of the drum. The punch head also includes bores to allow the sampling, testing and exhausting of the drum's contents or to introduce agents, such as neutralizing or foaming or gelling agents, into the drum to neutralize or solidify the drum's contents. Inert gases can also be introduced into the drum.
