What is isolation?

Isolation means creating physical barrier between process (energized) equipment, pipeline & vessels to prevent accidental release of hazardous materials or energy to work area.
Isolation prevent injury, accident or property damage by stopping the flow of hazardous material or energy.

Working on live or energized process equipment without positive isolation is very dangerous and it is unsafe condition.

So before starting any work on live equipment make sure live equipment is isolated from work area.

What are the types of Isolation?

1. Primary Isolation.
2. Positive Isolation.

Primary Isolation is simply closing the valves to stop the flow of hazardous energy while positive Isolation is removal of spool, valves and inserting blind between the flanges.

Some hazards energy sources in Sasref which need to be isolated.

• Machenical Isolation
• Chemical Isolation
• Electrical Isolation
• Thermal Isolation
• Gravitational Isolation
• Penumatic Isolation
• Radiation Isolation
• Hydrolic Isolation

What are the types of Machenical Isolation?

• Spade/Blind
• Double block & bleed
• Spectacle Blind
• Double valve
• Disconnect & block off
• Single valve

Sasref safety officer interview questions 

What is first line break?

First line break is a first step of maintenance preparation activities, where a workmen open valve and vessel fist time which still be in running temperature or pressure.

What is Blinding?

Inserting of a blind (spade) between two flanges where, spool removal is difficult to implement for isolation.

What are the types of Blind?

• Spectacle blind or figure of 8 blind
• Paddle blank or spade or slip blind
• Paddle space or spacer ring.
