Lockout/Tagout - What is the responsibility of the IC.
To ensure, all sources of energy are neutralized as soon as possible where there may be cause of injury or harm and to ensure a coordinated lockout takes place.
What are firefighters responsible for?
They are responsible to be familiar with this procedure and to inform their IC of any such risks that might endanger themselves or others.
Define Lockout.
The isolation of power and/or securing a control device to machinery, equipment, device or thing, which will secure it in the off or disconnected position with a locking/control device.
Define Locking/Control Device.
A device that physically isolates a machine, equipment, device or thing from its source of power: and can be secured and locked in the off or inoperative position.
Define Tagout.
The use of DANGER - DO NOT OPERATE tags to warn and forbid others from operating or moving the tagged device and to indicate who is performing the work.
Define Blanking Off
All lines and systems, which may introduce hazardous materials into the workplace, shall be physically disconnected or blanked off. The blanks should be sufficiently strong to withstand the line pressure and not be susceptible to corrosion by the material within the lines. Experience has shown that valves, which are closed, may leak. Therefore, merely shutting the valve is not adequate.
When should this SOG be followed - what is the goal.
Whenever sources of electrical, pneumatic, hydraulic, gas, water, steam, chemical or mechanical energy may present a safety hazard.
The goal is to be achieve a “Zero Energy State” on the machinery or equipment being worked on.
Summon qualified personnel.
Before de-energizing any equipment in order to lock it out, where possible, qualified maintenance, mechanical, electrical, or millwright personnel should be summoned to de-energize industrial equipment. Where qualified personnel are not immediately available to assist in this process, BFES personnel shall take such steps as necessary to prevent further injury to the patient and ensure the safety of emergency responders performing rescue operations.
Considerations during shutdown
- The amount and type of energy or hazard
- The method of controlling the main energy source
- Stored or secondary energy that stays in the system after the main source is turned off. Stored energy includes electricity in batteries and capacitors, volatile chemicals in piping systems or pistons that move back and forth after the equipments’ power supply is turned off.
- There may be more than 1 type of energy involved.
Stored or secondary energy.
Includes electricity in batteries and capacitors, volatile chemicals in piping systems or pistons that move back and forth after the equipments power supply is turned off.
Equipment Shutdown.
1-Once a machine is turned off and has stopped moving, the main disconnect switch must be opened and locked in the OFF position by placing a safety lock on the disconnect switch by the person tasked with lockout
2-Once the switch has been locked out, a check must be made to ensure that the item is inoperable. Attempt to restart he machine using the machines normal starting procedures after cribbing is inlace. If the item is still operational, contact the building manager to locate the proper disconnect switch. Repeat the above steps.
3-After switch has been locked out successfully, the person responsible tasked for the lockout must permanently fix a tag tot he lock.
4-The person responsible tasked with lockout must retain the key for their lock while their lock is in place.
5-The lock can only be removed after all work has been completed and equipment is safe and ready to operate.
6-Only the person responsible tasked with the lockout must remove the lock. This responsibility must NOT be delegated.
Equipment Isolation
1-Operate all energy isolating devices to ensure isolation from all energy sources.
2-Close valves, throw main disconnects and circuit breakers
3-Disconnect auxiliary power sources, i.e. electrical, steam, hydraulic, pneumatic
4-Never pull a switch under load.
5-Never remove a fuse instead of disconnecting.
6-In flowing liquid/solid applications, ensure that the blank-outs are performed.
7-Eliminate or neutralize energy reactors by use of chocks, wedges, blocking devices or elimination of secondary power source where necessary.
Applying Lockout/tagout devices.
1-Attach a lock and tag to all energy isolating devices, switches and valves
2-For equipment that cannot be locked out place a tag close to energy isolating device and assign personnel with a radio to stand-by lockouts to ensure that machinery power supply is not inadvertently turned on.
3-Only standard BFES devices shall be used.
4-When lockout is used all involved services must attach their personnel lock to the lockout device. Keys may be stored in a lock box to maintain control of the scene.
5-Fill out identifying tags completely when possible including: Name, telephone number, and department.
6-Notify IC and or Safety Officer when lock out is complete.
Control Stored Energy.
- Verify all moving parts are stopped and energy supply is locked out
- Confirm shutdown with responsible party
Removing Lockout
1-Make sure the equipment does not pose a hazard before leaving the scene
2-Notify IC and or Safety Officer of lockout removal
3-Confirm removal with responsible party
4-Confirm everyone in area that lockout is being removed
5-Each device must be moved by the person who put it on.
6-Responsible party will apply their own locks before BFES is removed
7-For elevator rescues, if there is no one available to hand over and the room is lockable, remove the lock and locking device and replace these with zip tie tied in the off position
