Lockout/Tagout is a planned safety procedure which involves turning off the energy supply of equipment and machinery whilst maintenance and repairs are being carried out. This procedure protects workers from danger and the machinery being set in motion. Once all of the work and repairs to the machinery have been checked and completed then all of the lockout equipment and locks can be removed ready for the machinery to commence safe operation again. Every company has a legal requirement ensuring that all machines which are being repaired or maintained have their energy sources turned off and locked out. This ‘locking off’ practice will prevent the unauthorised operation of the machine until all of the work has been completed.
