A containment apparatus includes a clamp having an axially extending passage and a containment assembly having an engagement element and a flexible elongated hose connected to the engagement element. A method of removing a fire sprinkler head from a pipe entails installing the clamp onto the pipe such that an end of said pipe and the sprinkler head extend from the clamp, and attaching the engagement element to the clamp so that the sprinkler head and the pipe end reside in the interior of the hose. The method further entails grasping the sprinkler head through the hose without breaching the sidewall of the hose, detaching the sprinkler head from the pipe, and releasing the sprinkler head to allow the sprinkler head and any residual water in the pipe to fall into and be contained by a lower portion of the hose. |
