(Wait for the punchline) This is a classic case of a little knowledge being dangerous thing, or in this case a very expensive one. Over the weekend we were called out by a client to identify floor tiles and adhesive of a floor, their refurbishment contractor had convinced them to remove as “They might be asbestos”. Concerns were raised when the “contractor” was also ripping up the asphalt substrate with the tiles attached and damage was being caused to the freshly decorated walls and skirting boards. No samples had been taken to identify the floor tiles and adhesive prior to work commencing, no plan of work, no risk assessment and interestingly no facilities to dispose of asbestos waste correctly. On my arrival the condition I found the room in was atrocious and if the tiles had been asbestos, I would have declared the site a disaster area. Yes, you read that right, ….if the tiles were asbestos……………. they aren’t. Through experience I could identify the tiles on site as modern non-asbestos thermoplastic, containing calcite instead of asbestos. This floor had been laid around 20 years ago, whereas asbestos hasn’t been used in floor tiles since the late 1980s. We have now taken samples to confirm my assessment, but its too late to save the floor substrate. To add to the agony, there had never been any need to remove the tiles anyway, even if they had been asbestos. The new tenant wants the area as a dance studio and all that was required was the floor to be over boarded and a new floor laid over the top. HSE and Government advice is not to lift asbestos floor tiles unless absolutely necessary but encapsulate by screed or over boarding. The asbestos risk from floor tiles is extremely low. Unfortunately for our client there is now the expense of reinstating the asphalt substrate, repairing the damage to the walls and skirting boards, plus the delays for the prospective tenant. All it needed to prevent this expensive mistake was a quick visit by us to identify the materials and work could have been completed for little time and cost. Far better than just taking a guess. As I say, “A little knowledge is a dangerous thing”
