Do you provide the chair and the scribe?

Yes — an independent chair, a dedicated scribe, or both, so your engineers contribute as team members instead of running the room.

Will the report be acceptable to DOSH?

We produce audit-ready reports built on recognised practice (consistent with IEC 61882) with traceable, owner-assigned actions.

How often should a HAZOP be revalidated?

Commonly every five years, or sooner after a significant modification, incident, or change in operating conditions. We'll advise based on your asset's risk profile and DOSH expectations.

What's the difference between HAZOP and HAZID?

HAZID is broader and earlier HAZOP is detailed and design-stage, using guide words against process nodes. Many projects need both.

Can you run a HAZOP for just a modification (MOC)?

Absolutely — a large share of our work is focused MOC studies, sized to the risk of the change.

HAZOP Consultant
Malaysia

Independent, experienced HAZOP and HAZID facilitation for oil & gas, petrochemical
& power facilities studies that are properly chaired, fully recorded & actually closed out.

The PISB Approach

Your team works safer and more efficiently with manuals they can actually understand.

What is a HAZOP study?

A HAZOP (Hazard and Operability study) is a structured, team-based review that examines a process design node by node, applying guide words no flow, more pressure, reverse, high temperature to each P&ID against its design intent. For every credible deviation, the team works through the cause, the consequence, the existing safeguards, and any recommendation needed. It’s one of the most widely required hazard identification techniques in high-hazard industry & the primary input to LOPA & SIL determination.

Why a weak HAZOP is more expensive than no HAZOP

A HAZOP is only as good as the engineer chairing it. Run it in-house under deadline pressure & get the predictable failure modes: nodes rushed, dominant voices unchallenged, deviations missed, and a recommendations register no one ever closes. On paper you’ve done a HAZOP. In reality you’ve created a documented record of hazards you knew about and didn’t act on the single most damaging exhibit in any incident investigation or DOSH enquiry.

An independent chair changes the economics. A missed high-consequence deviation found in a workshop costs a recommendation. The same deviation found after start-up costs a shutdown, a repair, lost production & potentially a major accident. With Malaysian enforcement tightening since the OSHA 1994 Amendment took effect in June 2024, a defensible, fully closed-out HAZOP isn’t a compliance chore; it’s one of the cheapest risk reductions available to you.

Our facilitators come from operating major oil & gas assets. They keep the team honest, challenge “it’s always been fine,” pace the sessions so quality holds to the last node & produce a study you can defend.

Our HAZOP & HAZID Services

New project HAZOP

Design- and FEED-stage studies that catch issues while they’re still drawings, not steel.

MOC & revalidation HAZOP

Focused studies for modifications, and periodic re-studies (typically every five years or after significant change) for brownfield assets.

HAZID

Broader, earlier hazard identification at concept stage, before the design is fixed.

Recommendation close-out support

Ranked, owner-assigned actions tracked to completion — not just listed.
