Policy Statement

This policy is intended to protect all employees from injuries resulting from:

  • the unexpected or accidental energizing or start up of machines or equipment, and
  • the release of stored energy or materials when working with equipment during service, repair, maintenance or operating activities.

This policy and its associated guidelines provide direction for the development of effective lockout/tagout programs to prevent such injuries.


Application

This policy applies to all employees of the City of Toronto, and all contractors and their sub-contractors working for the City.

Definitions

Equipment includes but is not limited to machinery, devices, stationary tools, vessels, pipes, tanks, and vehicles.

Energy source includes but is not limited to electrical, pneumatic, hydraulic, chemical, gravity, thermal, steam, tension, momentum, spring pressure, head pressure and line pressure (fluid/gas).

Lock means a keyed lock.

Lockout means disengaging all energy sources from equipment, safely releasing stored energy or materials, and securing the control device(s) in the "off" position with an approved lock, thereby rendering it incapable of operation, release or movement.

Tag means an approved/durable label that is made of non-conductive material, which provides information about the purpose of locking the equipment out, and particulars such as whose lock it is and the date/time.

Test means attempting to energize and/or operate equipment, following the implementation of a complete lockout to ensure the energy source has been locked out.

Control Device means a device that physically isolates equipment from its energy source, and can be secured, locked or isolated in the "off" or closed position (e.g. keyed locks, lockout bars, braces, line blanks, line caps, electrical disconnect switches, programmable logic controllers, blocks).
