Good thing the carpet wasn't easy to ignite...

I see a lot of other firm's equipment in the janitor closets of places I'm quoting.  Besides the usual (and oft
remarked upon) safety and regulatory concerns of unlabeled squirt bottles and other chemical containers, lack of MSDS books, unfiltered vacuums, etc., one notices quite a few vacuum cleaner cords of questionable provenance.  Think twisted, nicked cords, taped up repairs, ungrounded (those pesky third prongs keep pulling out), perhaps of too small a gauge to support the length of cord or the vacuum.

Here's a fun video of the potential result.

We figure it's better to check our crew's equipment regularly, than to have to move the file cabinet.
