Additionally, our engineers are well experienced in fuel farm design and underground fuel pod and refuelling systems design. We have provided AS1940 assessments addressing hydrocarbon release risk analysis and associated reports for the purpose of environmental compliance in relation to potential dangerous goods and hazardous chemicals loss of containment.

We are accredited and experienced in providing Hazardous Area Classifications (HAC), Hazardous Area Installation Design and Hazardous Area Installation Auditing.


Our Industrial Fire and Risk Engineers have assisted numerous oil and gas companies, including various supermajors, managing such risks across the various stages of their project lifecycle.

In many cases, the outcome of HAC involves both prescriptive assessments using Standards and Codes of Practice, as well as alternative methods using a ‘risk-based’ approach using numerical modelling.


Our team is competent and qualified to carry out initial design, modifications and auditing of power station assets in relation to fire risk, hazardous areas, hazardous chemicals storage and handling, fire protection and smoke management system design.

Typical fire hazards addressed by Mendham Consultants include the potential for the rapid development of large fires in turbine halls as a result of oil soaked pipe lagging igniting during maintenance shutdowns, lubricating oil leaks at bearings and pumps and bund fires.


Our engineers lead qualitative and quantitative risk assessments, human factor analysis and undertake Hazard Audits as part of an organisations’ permits and licensing conditions.

Our registered professional engineers are accredited Dangerous Goods Consultants with the Australasian Institute of Dangerous Goods Consultants (AIDGC) and registered by Queensland Government as Hazardous Area Installation Auditors.


Our engineers have considerable experience in design and auditing in locations such as Darwin’s East Arm Port and Iron Ore Wharf facilities and New Guinea’s Lihir Island. We have recently provided waste, oil and fuel services audits of major Queensland sea ports.

We have assisted numerous port operators and tenants with hazard related studies, including preliminary hazard analysis, fire safety studies, HAZOPs, emergency response planning, route selection analysis and development of oil spill contingency plans.


Our in depth understanding of the Defence project lifecycle, delivery protocols and Defence specific operational requirements allows us to form an integral part of the design team for any infrastructure project across the Defence sector.

Our team of engineers are accredited consultants with the Australasian Institute of Dangerous Goods Consultants and hold formal competencies in Hazardous Area Classification and Hazardous Area Installation Auditing.


We provide fire and risk, as well as safety engineering services to the water and wastewater treatment industries, including protection and design of chemical storage and dosing facilities, undertaking Hazardous Area Classification studies, auditing and leading process hazard analysis studies such as, HAZID and HAZOP.

Our team of risk engineers have significant experience in various water and wastewater treatment technologies, including desalination processes.


In addition to the safe storage of dangerous goods, it is particularly important that a risk-based approach to hazardous area classification in relation to potentially explosive atmosphere associated with flammable liquids, flammable gases and flammable solids storage is applied.

The prescriptive hazardous area zoning approach typically leads to significant exclusion zones within the laboratory making large areas unusable, so the risk based approach is recommended.


Hazardous chemicals storage facilities require assessment against various hazardous industry development assessment policies and legislative requirements before development approval is given. Typically, small storage facilities are readily assessed under the provisions of the available Australian Standards.

Large chemical warehousing facilities, including those forming part of regional distribution centres, often require the application of engineered solutions to ensure compliant, practical and cost effective designs.
