5.3 SHUTOFF & LOCKOUT POWER
Any individual that will be adjusting, servicing, maintaining, or clearing an obstruction from this machine needs
to ensure that this machine stays safely “OFF” until the adjustment, service, or maintenance has been
completed, or when the obstruction has been cleared, and that all guards, shields, and covers have been
restored to their original position. The safety of all individuals working on or around this machine, including
family members, are affected. The following procedure will be referred to throughout this manual, so be familiar
with the following steps.
5.3.1 Shutoff & Lockout Power Recommendations
1. Think, Plan and Check
a. Think through the entire procedure and identify all the steps that are required.
b. Plan what personnel will be involved, what needs to be shut down, what guards / shields need to be removed, and
how the equipment will be restarted.
c. Check the machine over to verify all power sources and stored energy have been identified including engines,
hydraulic and pneumatic systems, springs and accumulators, and suspended loads.
2. Communicate - Let everyone involved, including those working on or around this machine, that work is being done
which involves keeping this machine safely “OFF”.
3. Power Sources
a. LOCKOUT - Shut off engines and take the key, or physically lock the start/on switch or control. Disconnect any
power sources which are meant to be disconnected (i.e. electrical, hydraulic, and PTO of pull-type units).
b. TAGOUT - Place a tag on the machine noting the reason for the power source being tagged out and what work is
being done. This is particularly important if the power source is not within your sight and/or will need to be isolated
for a longer period of time.
4. Stored Energy - Neutralize all stored energy from its power source. Ensure that this machine is level, set the parking
brake, and chock the wheels. Disconnect electricity, block moveable parts, release or block spring energy, release
pressure from hydraulic and pneumatic lines, and lower suspended parts to a resting position.
5. Test - Do a complete test and personally double check all of the above steps to verify that all of the power sources are
actually disconnected and locked out.
6. Restore Power - When the work has been completed, follow the same basic procedures, ensuring that all individuals
working on or around this machine are safely clear of the machine before locks and tags are removed and power is
restored.
It is important that everyone who works on this equipment is properly
trained to help ensure that they are familiar with this procedure and
that they follow the steps outlined above. This manual will remind you
when to Shutoff & Lockout Power.
