Difficult to explain this one ...but I give it a try.
An electrical wholesalers.
Cable department.
4 meter lengths of steel trunking for cable runs ect.
Come off the lorry in cradles which are forklifted off side on.
In the warehouse we stacked them up 4 high but end on. So you had to pick them up manoeuvre into the space & they stacked up with the feet cups locating in the tops of the lower cradles arms.
So there I am lifting this cradle on top of three others, I can see that the two cups nearest me are just a little bit not far enough in to drop on so I give a touch more forward...careful now bit more bit more...bit of resistance...clunk...
The top of the cradle had hit a 6'' pipe for the sprinkler system.
Right at a 90* bend, the joint gave way & the water started coming out.
Now with automatic sprinkler systems if the pressure drops anywhere the pumps kick in & in this case a huge diesel pump located in a shed right next to the 20,000 gallon water tank.
I'm sitting on this electric forklift when this torrent of water hits me...
The fire alarms went off & general panic ensued throughout the building...
I shot up to an office & blurted out what had happened, keys were found & a posse rushed to the pump house to kill the pump.
There are two of these pumps so if one fails the other kicks in...Turned the first one off...the other one fires up...
Sorted out the shut down fail safe in the end...
By the time this had been done the Fire-brigade had turned up & the cable store were under 6'' or so of water...
Spent the rest of the day sweeping water out...
I was talking to the bloke who came to repair the pipe the next day & he said that the join that had given way was only on a 1/4 of an inch so wasn't surprised it had given way...
Some years later after I had left I bumped into someone who had been working there at the same time & he told me it had been done again...

Making up since 2007, sometimes it's true...Honest...
