Energy remaining in machines and equipment after shutdown can expose workers to risk during maintenance or servicing. If not properly controlled, this energy can lead to serious injuries or fatalities (SIFs).
Before starting work, consider potential sources of stored energy that may include:
- Mechanical – objects under tension or
compression (springs/bungees) - Hydraulic – pressurized liquids (lifts,
pressurized vessels, pressure washer) - Pneumatic – compressed air (tools such as nail and spray guns)
- Chemical – chemical reactions (damaged batteries, gas tanks)
- Thermal – residual heat (hot engines or tools)
- Gravitational – elevated or suspended objects
Proper lockout/tagout and other safety practices help prevent stored energy release injuries. These practices include
securing loads, controlling the work area with proper barricades and boundaries, being aware of your work scope
and potential effects on those working nearby, and following proper work release and authorization procedures.
Discussion:
1. Identify two examples of stored energy that can be found on UCOR worksites, including office areas.
2. Discuss stored energy controls and practices that keep yourself and those around you safe.
