Alcoa UGL Asset Services - Energy Isolation

Equipment that has been purchased and equipment that is designed includes lockable isolation points for hazardous energy sources. Each isolation point is labelled with uniqued identifier.<br>Critical Risk Ref. 6.1

All hazardous energy sources shall be identified and de-energised/isolated prior to working on equipment/systems, with protection of services that cannot be isolated.<br>Critical Risk Ref. 6.2

In instances where electrical energy isolation is not practicable, appropriate safe working methodology has been developed and approved, for implementation by competent workers.<br>Critical Risk Ref. 6.2

Work planning includes identification and isolation of sources of hazardous energy by a competent supervisor.<br>Critical Risk Ref. 6.4

A 'check for dead' test shall be undertaken prior to working on equipment/systems to verify the equipment/systems is in a zero energy state. The 'check for dead' test must be conducted by a competent person who is authorised to operate the equipment under 'test' conditions.<br>Critical Risk Ref. 6.3

Competency requirements for personnel require to isolate (AIO) or work on (protected person) isolated plant/equipment has been identified and includes: - trained in EIMS-4-9605 energy isolation procedure.<br>Critical Risk Ref. 6.7

Competency requirements for personnel require to isolate (AIO) or work on (protected person) isolated plant/equipment has been identified and includes: - isolation to equipment as listed on EIMS-4-9605 or site processes.<br>Critical Risk Ref. 6.7

Competency requirements for personnel require to isolate (AIO) or work on (protected person) isolated plant/equipment has been identified and includes: - confirms isolation (free from harms, energy)<br>Critical Risk Ref. 6.7

Competency requirements for personnel require to isolate (AIO) or work on (protected person) isolated plant/equipment has been identified and includes: - development of isolation list.<br>Critical Risk Ref. 6.7

Competency requirements for personnel require to isolate (AIO) or work on (protected person) isolated plant/equipment has been identified and includes: - placement of danger tags/locks and control group isolations before working.<br>Critical Risk Ref. 6.7

All authorised isolation officer are appointed in working by the project/operations manager and appointments are recorded. Roles and reasonability are clearly appointment letter.

Isolation work instructions are developed, reviewed and approved by authorised isolation officers.

Where potentially harmful energy sources are present, the isolation process includes the specific steps for releasing the stored energy to archive "zero state energy" of other means of controlling potential energy sources.

Energy isolations activities are authorised by a permit which identifies each isolation point and specifies the test requirements for the presence of hazardous materials/stored energy. <br>Critical Risk Ref. 6.6

Isolation points are Cleary identified, proven, labeled, locked and controller to prevent inadvertent energising.<br>Critical Risk Ref. 6.8

All personnel who are about to commence working on the plant or equipment must conduct an isolation check before placement of a danger tag/lock (function try/test). The check includes either; physical confirmation isolation lock and tag is in place for field isolation, or ensuring lock box officer lock and confirmation tag is in place for lockbox isolations.<br>Critical Risk Ref. 6.5
