SWIFT (Structured What--If Technique) alternative to HAZOP

SWIFT (Structured What--If Technique) alternative to HAZOP

Pengurus saya di Silverstone yang saya anggap sebagai Guru OSH saya mencadangkan untuk process tidak serumit di Oil & Gas Industry dianalisa risikonya menggunakan SWIFT. SWIFT ini adalah teknik penganalisaan risiko yang dipermudahkan dari HAZOP.

Berikut adalah satu kajian kes yang merujuk tugasan sebenar dan digunakan dalam latihan.

CASE STUDY

A group of workers in Silverstone Berhad have been assigned to classifying, packaging and labelling 50 drums of a 200 litres (55 US gallon) flammable liquid to 5-litres package.  This task also includes transportation and storage.         

SOLUTION

1.    STEP 1. DEVELOPING THE “WHAT-IF” QUESTIONS (Column A).

Using the documents available (SDS, label, etc.) and knowledge and experienced of the team’s members, “What-If” questions can be formulated around 5M (Man, Material, Machine, Method and Medium) hazards and risks.  These hazards and risks can be considered during routine, un-routine and emergency operations.   

                      i.        MAN - Worker no knowledge or experience about the task?

                    ii.        MATERIAL - Drum is mislabeled? Unsure the material?

                   iii.        MATERIAL - Wrong liquid in the drum?

                   iv.        MATERIAL - Drum is misweighed?

                    v.        MARTIAL - Drum is corroded?

                   vi.        MACHINE - Drum hoist is not used?

                  vii.        MACHINE - No proper clamp or drum lifter?

                viii.        MACHINE - Drum hoist fails?

                   ix.        METHOD - No SOP / SDS available?

                    x.        MEDIUM - Are floor coverings suitable for the work carried out there? 

2.    STEP 2. DETERMINING THE ANSWERS

Team members need to determining the answerS to each questions (Column B) based ob their knowledge and experience, and to refer documents available (SDS, label, etc.) and previous accidents/incidents reports.

3.    STEP 3. REVIEWING THE FREQUENCY AND POTENTIAL

By reviewing the frequency potential 5M’s hazards and risks (Column C and D) can point out the potentials for not only safety and health improvements but also the opportunity to minimize operating and quality problems.  

4.    STEP 4. RECOMMENDATIONS

Team members need to assess the hazards and risk, and making recommendations. The team members need to make judgments regarding the level of hazards and risks and it’s acceptability (and also practicable).  

5.    STEP 5. MAKING EFFECTIVE RECOMMENDATIONS

Making effective recommendations.  The make up of the organization generally determines to whom and how the results get reported.  Usually, the department or plant manager is the approval of this analysis.  The leader of the team member will forward this analysis to who has been assigned the responsibility to handle the raised concern (PIC) and time frame (Column F).
