    • 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.
    • 一种用于从滚筒收集危险流体的代表性样品,然后从取样器排出的设备和方法,而不用从滚筒中取出采样器,以防止操作者暴露于有害流体。 收集的样品通过可滑动的柱塞沿着中空管的内部通道朝着保持在其顶部的排水口移动,同时管的底部保持浸入罐内。 此后采样器的断开结构可以在管子保持浸没的同时使其浸入和脱出部分之间分离,以便在采样完成之后保护操作者,从而可以永久地处理被抽取的滚筒中的分离部分。 不可逆的柱塞移动功能阻止任何重复使用取样器的尝试。
