Types of Energy

Dangerous energy sources can take many forms, including:

Electrical Energy

Commonly found powering nearly all workplace equipment

Hydraulic Energy

Stored within a pressurised liquid. When under pressure, the fluid can be used to move heavy objects, machinery, or equipment. Examples include automotive car lifts, forklifts, injection moulding machines, power presses, cutting equipment and pumps.

Mechanical Energy

Contained in an item under tension, for example a spring that is compressed or coiled will have stored energy which will be released in the form of movement when the spring expands. Can be found in all machinery with moving parts.

Thermal Energy

Commonly found in ovens or freezers (hot or cold)

Pneumatic Energy

Most commonly found powering machinery via compressed air or gas

Potential Energy

Found in compressed springs or suspended weights


Lock-out Tag-out Try-out Programme

A well-designed Lock-out Tag-out Try-out programme ensures all the necessary procedures are correctly written and followed.

All procedures for the control of hazardous energy including planning for preparation for shutdown, equipment isolation, lockout device application, release of stored energy and verification of energy isolation of equipment should be identified and written out.

Isolation Guidance

Isolation involves following the correct steps to disconnect or block all energy sources to make equipment safe to work on without the risk of the machine being re-activated when it shouldn't.

Find out about the steps involved for a successful equipment isolation and re-activation once maintenance, repairs or cleaning has been completed.
