SafeWork NSW are now investigating the incident.
It's not the first incident tradies have had on the job with their genitals.
In 2018 a Welsh tradesman took a trip to the emergency ward after he managed to get his penis stuck in a spanner.
Unfortunately, doctors and nurses were unable to free the man's penis from the spanner and were forced to call in the fire brigade for their help.
Arriving at Royal Gwent Hospital, the two fire crews were able to free the worker's genitals using specialist cutting equipment.
The spokesperson for the fire service described that the man had "taken tightening nuts to a new level."
South Wales Fire and Rescue added in a tweet: "If you're using tools, make sure you're handling as the manufacturer recommends."
