Identify All Energy Sources
Identify all energy sources affecting the equipment or machinery. Identify the various energy forms to be locked
out such as electrical, momentum, pneumatic, hydraulic,
steam, and gravity. |

Definition
IDENTIFY THE PARTS TO BE LOCKED OUT
OR ISOLATED
Identify systems that affect, or are affected by, the work
being performed. These may include primary, secondary,
backup, or emergency systems and interlocked remote
equipment.
Review the current system drawings for remote energy
sources and, where required, identify and confirm with the
client or owner the existence and location of any switches,
power sources, controls, interlocks, or other devices
necessary to isolate the system.
Remember that equipment may also be affected by
• time restrictions for completing the work
• time-activated devices. |

VERIFY ZERO-ENERGY STATE
verify that all personnel are clear of the equipment. Then try, with extreme caution, to start the equipment manually
Test the system to ensure that all electrical components are de-energized and de-activated, including interlocking and dependent systems that could feed into the system,either mechanically or electrically.
YES OR NO
No = hazardous energy not controlled Proceed to Step 2
Yes = Step 10 |

COMMUNICATE THAT WORK IS COMPLETE
AND THAT ALL PERSONNEL ARE CLEAR
• Ensure that personnel are clear of the locked-out equipment, machinery, or system.
• Remove only your tags and locks.
• Tell personnel that were originally informed of the lockout that the equipment, machinery, or system is no longer locked out. |

• maintenance, repair, installation, and other jobs can be carried out safely
• records are kept. |

| Lockout is a procedure that: |
|
Definition
| prevents the release of hazardous energy. It often involves workers using a padlock to keep a switch in the “off” position, or to isolate the energy of moving parts |
|

Term
A written procedure helps to ensure that lockout and
tagging have been thoroughly and effectively carried out before work begins. It should include: |
|
Definition
• training requirements for workers and supervisors
• quality, type, and colour of locks, scissors, chains, blanks, blinds, and other lockout devices
• method of identifying lock owners
• control of keys for locks
• colour, shape, size, and material for tags
• method of securing tags and information to be included
• communication and authorization procedure for shutting down and starting up machinery and equipment
• record-keeping requirements
• itemized steps to meet lockout objectives. |
