ENERGY ISOLATION

This step requires conducting a JSA to implement isolation requirements and a corresponding de-isolation requirements to return the equipment to the de-isolated state. The JSA should cover all stages of the isolation activity as follows:

• Preparatory work for the isolation
• Installation/removal and proving of the isolation
• The integrity of the isolation during intrusive work
• Requirements for testing and reinstatement of plant

ENERGY ISOLATION

Mechanical isolation shall always be used for work involving:

• Confined space entry
• Naked flame/spark potential hot work on hazardous areas

ENERGY ISOLATION

• Positive Isolation (Mechanical Isolation): removal of a spool and fitting of blinds, or fitting of a spade or spectacle blind
• Proved Isolation: Valve isolation where effectiveness of the isolation can be confirmed via vent/bleed points
• Non-Proved Isolation: Valve isolation. No provision to confirm effectiveness of valve
