Comparison of technical evidence in MHI safety reports

Published technical case study

Project evidence

Turning complex risk questions into defensible decisions.

A useful safety report does more than satisfy a document list. It shows how scenarios, assumptions, safeguards and conclusions connect.

Question: What separates a reviewable MHI safety report from one that leaves critical evidence unclear?
Approach: Compare scope definition, scenario traceability, risk criteria, action ownership and reporting quality.
Decision value: Clearer regulatory readiness, stronger challenge of assumptions and a more usable basis for risk-reduction decisions.

Focus the reading list on the questions your facility is working through.

Before you engage

Questions facilities ask before scoping the work.

These answers provide a practical starting point. The requirements and assessment scope for your facility will depend on your substances, processes, quantities and planned changes.

Browse practical starting points, then involve an engineer when the decision depends on your site.

01 / MHI fundamentals

Understand the starting point

MHI fundamentalsWhat is a Major Hazard Installation?

An MHI is an installation where the nature and quantity of hazardous substances, together with credible incident consequences, bring the facility within South Africa’s Major Hazard Installation regulatory framework.

The determination depends on the real facility and cannot be made from a generic checklist alone.

Explore the assessment process

MHI fundamentalsHow do I know whether my facility qualifies as an MHI?

Start with a structured screening of hazardous substances, maximum inventories, processes, site layout and potential consequences beyond the installation.

An engineer can then advise whether further assessment by an Approved Inspection Authority is required.

Request an MHI screening discussion

02 / Assessments and compliance

Prepare useful evidence

Assessments and complianceWhen is an MHI risk assessment required?

An assessment may be required for a qualifying existing installation, a new facility, an expansion or a material change that alters hazardous inventories, processes, layout or the risk basis.

Periodic review requirements also apply. Confirm the trigger against the current regulations and your facility circumstances.

Explore MHI risk assessment support

Assessments and complianceWhat information does MMRisk need before starting?

A useful first package includes the facility location, substance inventory and maximum quantities, process description, site and equipment layouts, existing studies and details of the proposed project or change.

MMRisk will identify gaps during scoping.

Use the MHI preparation checklist

Assessments and complianceHow long does an assessment process usually take?

The programme depends on facility complexity, information readiness, modelling scope, stakeholder input and review cycles.

MMRisk confirms milestones after reviewing the available information rather than promising a standard duration that may not fit the work.

Discuss your assessment pathway

03 / Facility changes and expansion

Test changes before they become costly

Facility changes and expansionCan MMRisk assist with a new facility or expansion?

Yes. Early screening, HAZID or HAZOP facilitation, consequence modelling and risk assessment can help test site, layout and design decisions before they become expensive to change.

Scope the decision against the planned change, information available and potential consequences.

Discuss a planned facility change

04 / HAZOP and risk studies

Choose the right study

HAZOP and risk studiesDoes MMRisk provide HAZOP facilitation?

Yes. MMRisk facilitates structured HAZOP and hazard-identification workshops for new designs, modifications and existing operations.

The work can include preparation, guide-word review, action recording and technical reporting matched to the agreed scope.

Explore HAZOP facilitation

05 / Training

Build practical capability

TrainingCan training be customised for our organisation?

Yes. Content can be shaped around participant roles, the methods they need to use and relevant facility scenarios.

The agreed programme will state the delivery format, learning outcomes and any prerequisites.
