Self explainatory, if we read it carefully.
...apa itu GAJAH...
MOC is system for managing changes and communicate these changes to affected personnel effectively
...bagaimana nak menggunakan GAJAH...
..You need to establish own documents how to apply MOC in your organization..
Just some basic structure to be considered (which I believe apply to either "procedural" changes or "engineering" changes):
1. Proposed change (kire macam problem solving la kot)
- Kebiasaannye idea "to change" nih datang dari (outcome of) procedure review, audit, lesson-learnt, suggestion, inspections, risk assessment, HAZID engineering review, etc.
- Kalu bole try establish satu form utk alteration control or wateva you wanna call it for record purpose.
2. Does the change have a potential impact on HSE? (since we are talking from HSE perspective)
- If Yes – refer kat Item 3
- If No – terus refer kat Item 4 (skip item 3)
3. Assess the change
- Apply HEMP or HIRARC or anything to do with risk assessment i.e. according to your organisation’s defined protocol. Samada nak pakai qualitative or quantitative tu based on the criticality of the change. (Tengok Note A).
- Kalau risk evaluated tu within ALARP, proceed with the change. Kalau tak, consider any other alternative (propose with other changes – pergi balik Item 1).
- Identify control/recovery measure macam biasa.
4. Implement the change
- Design the change i.e. based kat Item 1 (kire macam detailed solution utk solve problem regardless it is a procedural change or equipment change)
- Plan the implementation of change (how to ... who will... etc).
- Document the change (Tengok Note B & Note C)
- Communicate and train personnel who are affected by the change. (Refer Note D).
5. Monitor the change
- Monitor the execution dan ongoing operation of the change utk ensure yg change tu implemented as intended dan yg penting takde further HSE issues arise.
- Kalau ada issue, go back to Item 3 and so fourth.
- For some organisation, they do have Post MOC Audit.
Kebiasaannye: higher the risk – more quantitative it would be, secara general jek. In hydrocarbon business for example, HAZOP is required if the change dealing with engineering design such as reservoir or geological/geophysical changes, well design/construction changes, ataupun any major changes to operational processes kat offshore tu. Or, we may conduct FEA or QRA if let say we want to change the type of firewall or bulkhead or anything to do with fire and explosive protection (passive/active) kat mana2 offshore facilities.
In the other hand, we may just proceed with the qualitative thingy i.e. BowTie or HIRARC or any other HEMP tools if the risk of change is low/medium such as personal changes (new personnel/transferred/promoted), any changes to the HSEMS elements, etc. Tapi perlu diingat, definition of Low/Medium/High risk tu depend kat masing2 punye organisation.
Any changes in document (procedural changes) kena follow your own QA procedure (Document Control Procedure) – ISO 9001.
Any engineering changes (structural/electrical/instrumentation/mechanical/etc) must be recorded on the specification diagram/drawing. Bende nih sangat penting, especially bila nak refurbish or convert or revamp facility tu esok lusa. Bukan apa, skang nih banyak tanker nak transform jadik FSO la...FPSO nak tambah drilling capability jadik FPDSO la...macam2 lagik le...macam Ford Mustang tukar jadik Decepticon atau Chevy Camaro tukar jadik Autobot dlm cerita Transformer tu.
Utk changes yg memerlukan training, bende nih kena kowtim dgn HR or Training & Development punye Team. Kena masukkan dalam training plan etc. Utk minor changes (especially procedural changes), boleh just pakai HSE Alert or HSE Bulletin or whateva as long as boleh communicate kat relevant parties..
