RE: FW: Dirty Mop Water
I agree wholeheartedly that prevention is the way to go. However, no matter how good your processs or how well designed you plant is, there are going to be leaks at some point in time. As far as I know, any plant that has never had a machine leak, or never needed to clean up a spill, is likely not running. In those cases, I'd recommend a sqeegee approach is a good alternative, as long as it is feasible, then mopping. I don't think we should avoid providing a reasonable suggestion to situtations that we know are going to happen, and advocate prevention as the only answer. The best laid plans...

What happened to prevention? If the material did NOT LEAK it would not
need to be cleaned up. The coolant is best used to cool parts not to
lubricate the floor. Let's hear instead from shops practicing Poka-Yoke
and PREVENTING the spills and leaks, not cleaning them up after the fact
and worring about disposing the squeege residues or the mop water. I am
sure Ralph Cooper would agree with this.
