Mercury Spills

Mercury Spills: We have a small amount of mercury in a thick-walled test tube, which only comes out once a year and is handled by the teacher. I do not have a spill kit for this. I was wondering where do I buy one, or can I make one up? Also, what would be the procedure in the event of a mercury spill. I know evacuation would be a must, but that is all I know. I have also been thinking about placing this glass test tube in an appropriate plastic bottle to avoid a spill.

Any recommendations would be appreciated.
