Are written lockout/tagout procedures required for all machines or equipment being repaired or serviced?
Yes – written lockout/tagout procedures are required unless: there is no potential for stored energy; there is only a single, easily identifiable energy source and it is isolated by a single lockout device; isolation results in complete deenergization; lockout is under complete control of the employee, AND there is no history of accidents with the particular machine or equipment.
