A precision equipment manufacturing company moved into a new office that had linoleum floors, immediately slipping accidents started to happen on one floor at an alarmingly high rate.
After puzzling over the problem, the health and safety advisor contacted the cleaning product supplier for advice, but the supplier couldn’t figure out what was happening either, as their product was not known to cause such problems. Eventually the advisor spoke with the cleaner and discovered that she was using regular washing up liquid to clean the floors with as the substance she was suppose to use was stored downstairs and it was "inconvenient" for her to go down and get it!
The offending floor was immediately cleaned using the right product and the slip resistance of the floor improved instantly.
Needless to say, the floor cleaning substance is now stored on each floor in the building so the cleaner never resorts to using washing up liquid again.
