    • The procedure must identify a method to account for all persons exposed to hazardous energy during lockout/tagout
    • Lockout/tagout application must clearly identify when and where lockout and tagout apply, with specific definitions and safety measures for tagout procedures without a lock
    • Details for removing locks or tags when the installer is unavailable must be identified, and attempts to locate the installer must be made before removal
    • Steps to be taken when the job or task requiring lockout/tagout is completed, including tests, visual inspections, and notification of employees responsible for operating the equipment, need to be included in the procedure
    • The procedure must clearly identify the steps and responsibilities when the job or task requiring lockout/tagout is interrupted temporarily for testing or positioning of equipment
    • Establishing and verifying an electrically safe work condition must include specific steps, such as determining all possible sources of electrical supply, visually verifying disconnecting devices, and testing for the absence of voltage
    • The order of steps for establishing and verifying an electrically safe work condition must be followed if feasible
    • The procedure must contain a statement requiring the area to be inspected to ensure that nonessential items have been removed and that all personnel are clear of exposure to dangerous conditions resulting from re-energizing the service
    • Temporary release for testing and positioning must follow identical steps as the steps for return to service
    • The procedure must establish a process for establishing and verifying an electrically safe work condition, including steps such as applying lockout/tagout devices and testing for the absence of voltage
