A young tradie has been rushed to an Australian hospital after getting his genitals caught in a belt sander.

The unfortunate accident happened on Friday at a worksite in Mosman, on Sydney's north shore.

It's unclear what the 18-year-old was doing to the device, however for some unknown reason he got his trousers and genitals caught in the machine.

Fire and Rescue crews and two ambulance crews were called to the scene, however due to the severity of his injuries he was taken to hospital in a stable condition to have the machinery carefully removed.

A spokesperson for the NSW Ambulance told Daily Mail Australia that the man had suffered suspected tears in his genital area.

SafeWork NSW is now investigating the incident. It's not known if there will be any lasting damage.
