1.0
PURPOSE: To ensure that all individuals, college staff/students, and outside parties are protected from accidental or unexpected activation of electrical, mechanical, hydraulic, pneumatic, thermal (steam), chemical (natural (natural gas or propane) and all other forms of energy.
2.0
SCOPE These minimum requirements are based on de-energization de-energization of all energy sources, which could cause injury or death. All employees, contractors, students and visitors shall comply with the procedure.
3.0
DEFINITIONS: Lock-out is defined as the practice of using keyed security devices (locks) (locks) to prevent the unexpected start-up or release of stored energy. Tag-out is defined as the practice of using tags in conjunction with locks to increase the visibility and awareness that machinery/equipment is not to be energized or activated. Absent Worker is a worker who has placed a lock on an isolation device but is not available to remove the lock.
4.0
RESPONSIBILITIES: Responsibility Responsibility for complying with this procedure is binding upon all employees, contractors, students and visitors. The employer will instruct all persons (including those who are new or transferred) who may be required to follow this procedure in the purpose and use of the lock-out/tag-out procedure. Project Coordinators or Budget Managers where applicable, are responsible for ensuring that all contractors are adequately trained in Fanshawe College’s lock-out tag-out procedures, adhere to these procedures and supply their own locks and tags for each isolation device. Health and Safety Services and the Joint Health and Safety Committees will audit this lockout procedure.
5.0 PROCEDURE 5.1 GENERAL All equipment shall be locked out to protect against accidental or inadvertent operation when such operation could cause injury to personnel. Do not attempt to operate any switch, valve, or other e nergy-isolating nergy-isolating device bearing a lock or tag. When multi-trades (or persons) are involved in a t ask, each person involved shall apply their own lock and tag, using a hasp as necessary.
5.2 SPECIFIC 5.2.1 Prepare for Shutdown – Identify all types of energy sources that apply to the equipment/machine being locked out. Identify types and numbers of lock-out and tag-out devices required. 5.2.2 Shut Down – Shut down machine/equipment by the normal stopping procedure (i.e. turn off valves, switches, stop button, etc.) Visually check to see all motors and other moving parts have come to a complete stop. 5.2.3 Isolate – Operate the switch, valve, or other e nergy-isolating device so that all energy sources (electrical, mechanical, hydraulic, etc.) are isolated from the equipment. Dissipate stored energy, such as that in capacitors, springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc., by grounding, repositioning, blocking, bleeding-down, etc. 5.2.4 Lock-out/tag-out – Apply an individual lock and tag to each energy-isolating device. Each workers’ name, date, and reason for lock-out must be printed on the tag. Where several workers are involved in locking out the same energy-isolating device the use of a multi-lock hasp may be required. 5.2.5 Verify Isolation of Equipment – Verify that energy is locked out by pressing all start buttons or activating controls. Return all controls to the off position and periodically verify isolation until service or maintenance is complete. 6.0
REMOVING LOCKS AND TAGS 6.1 GENERAL Upon completion of work, ensure equipment is intact and all tools and other items have been removed. Check the equipment area to ensure no one is likely to be at risk upon re-energization of equipment/machine. Locks and tags are to be removed only by the person who placed them on the machine/equipment.
