710 Energy Control Program (Lockout/Tagout)

• the type and magnitude of the energy,


• the hazards of the energy to be controlled, and


• the method or means to control the energy.

2. Your maintenance team is going to work on equipment in your workplace. What is the

first step to controlling energy for this equipment?

a. Identify the equipment

b. Energize equipment

c. Apply LOTO devices

d. Dissipate potential energy

6.3 Shutting Down Machinery or Equipment

The machine or equipment must be turned off or shut down using the procedures established for it to
avoid any additional or increased hazards to workers as a result of the unexpected machine or
equipment startup or stoppage.

Isolating Machinery or Equipment

All energy-isolating devices that are needed to control the machine's energy source must be located.
These devices must then be used to isolate the machine or equipment from its energy source(s).

De-energizing equipment means isolating it from its energy source and controlling potential energy so
that no energy can flow to the equipment. The method you use to de-energize equipment depends on
the form of energy and the means available to control it.

Below is a list of safe practices for de-energizing equipment.

• disconnecting motors from the equipment


• isolating electrical circuits


• disconnecting equipment from energy sources


• blocking the fluid flow in hydraulic, pneumatic, or steam systems with control valves or by
  capping or blanking the lines


• blocking equipment parts that could be moved by gravity
