This incredible video depicts a whole catalogue of health and safety wrong doings and bad working procedures.

In the first instance the "driver" tracks an 835kg Takeuchi TB108 on to a piece of plywood that is spanning a wide trench, then he proceeds to slew over the side without the tracks extended for stability, he then tries to dig a bucketful at full reach which in turn produce's the inevitable result!

The guy was very lucky to be able to walk away from this accident.

Sensitive readers please be aware that there is some rather colourful language towards the end of this video.

Although this video is a complete horror show on how not to approach a job I am sure that incidents like this are very rare. Please don't have nightmares!
