I know when I visit a company with a great lockout program because, when needed, it happens effortlessly. Workers attack machinery problems that require lockout to be applied without any hesitation. They notify the necessary people nearby, know what has to be turned off, what controls measures are applied, and where the lockout equipment is kept nearby. Then they test for effectiveness before flowing into the repair or service work that needs to be done.
What stands out during the demonstration is this is the normal or routine way they perform their duties.
