Abstract
A device and method for collecting a representative sample of hazardous fluid from a drum, and then disposing of the sampler, without ever removing the sampler from the drum so as to safeguard the operator from exposure to the hazardous fluid. The collected sample is moved, by a slidable plunger, along the inner channel of a hollow tube toward a drainage opening maintained at the top thereof while the bottom of the tube remains immersed within the tank. A break-apart construction of the sampler thereafter enables separation between its immersed and emergent portions, while the tube remains immersed, to safeguard the operator after sampling has been completed by enabling permanent disposal of the separated portions in the drum being sampled. An irreversible plunger movement feature discourages any attempt to reuse the sampler.
