ISOLATION AND TAGGING

You isolate to stop :

• A motor from switching on (or off)

• A substance such as liquid, gas or powder getting in or out

• Two hazardous substances mixing

3

ISOLATION AND TAGGINGYou isolate to :

• Allow maintenance or inspection

• Take a piece of plant out of service for a certain time

• Change a process

• Make sure that even isolated plant cannot be started by mistake somewhere else

• Stop the chance of human error or mechanical failure

Isolation of equipment will make sure:

• That it will not start while you are working on it

• All persons working on the machine are protected

• Damage to the equipment is prevented.

PERSONAL DANGER

A Personal Danger tag provides protection for personnel working on equipment.

No person shall de-isolate, operate any switch or valve whilst a personal

danger tag is in place.

The only person who can place or remove this tag is the person whose name appears on the tag.

COMMISSIONING AND TESTING

This tag gives an employee exclusive control over the plant operation.

It is used during commissioning, calibration, testing, inspection and maintenance when equipment is required to be in operating mode.

INFORMATION TAGS

These tags are used to pass on information which may reduce inefficiencies, doubling up or constant reporting.

ISOLATION AND TAGGING

Equipment must be isolated and tagged with an OUT OF SERVICE tag at each isolation point

13

ISOLATION AND TAGGING

Switches and valves must be switched to the isolated position and tagged by an authorised person

14

Each person working on the equipment must have a PERSONAL DANGER tag at each isolation point

15

ISOLATION AND TAGGING

Before starting work, test the isolation. Discharge any energy that MIGHT be stored in the system.

Each person must remove his or her own Personal Danger Tag at the completion of the job or prior to leaving the work site.

If the task is incomplete, the Out of Service tag remains on the isolation point.

Always communicate isolation conditions with your supervisor and the supervisor of the next crew

coming on shift.
