8. Isolation

8.5 Assess machinery for components with potential stored energy under tension or pressure

RISK – Stored energy releasing in an unsafe manner

Machinery includes cables and belts.  Pressure can be negative or positive and includes hydraulic or air.

 

 

 

Stored energy can be in the form of:

  • Mechanical
  • Hydraulic
  • Pneumatic
  • Chemical
  • Thermal
  • Electrical
  • Kinetic

 

 

Stored energy can be found in:

  • Moving parts
  • Devices and equipment
  • Plant and machinery
  • Pre- and Post-tensioned concrete
  • Sources of electricity

 

 

Inadequate identification and release of stored energy can result in serious injury to anyone in the area, adverse environmental impact and property damage

8.4 All isolation points must be clearly identified, proven isolated, tagged, locked and controlled to prevent inadvertent energisation

8.A Test before touch - Test for hazardous material and stored energy prior to breaking containment systems

8.B Release any stored energy prior to opening hoses or vessels under pressure or working with belts and cables under tension
