What types of energy sources must be controlled under LOTO?

The correct choice identifies all relevant energy sources that must be managed under the Lockout/Tagout (LOTO) standard, which is designed to ensure the safety of workers performing maintenance or servicing on machines and equipment.

In LOTO procedures, it’s essential to address all potential energy sources that could pose a risk during maintenance activities. Electrical energy is commonly recognized, but it’s equally important to consider mechanical energy (that can cause unexpected machine movements), hydraulic energy (which can lead to sudden releases of fluid), pneumatic energy (which can trigger fast-moving parts), thermal energy (that can cause burns or ignite combustible materials), and chemical energy (that can create hazardous situations).

By requiring control over this comprehensive range of energy sources, the LOTO standard helps protect workers from accidents and injuries that could result from the unexpected release of stored energy during maintenance work. This understanding is vital for anyone involved in industrial operations to maintain a safe working environment.
