MHI Risk Assessment

We believe that the MHI Assessment is essential as a basis for ongoing decision making and risk management,  we develop our assessments to be easily applied with a major hazard installation.

Using MHI Risk Assessment techniques( SANS 1461 methodology) we identify potential hazards to major hazard establishment including plant, process and personnel; we quantitatively assess the likelihood of occurrence  of a major incident which will impact the people on site and society offsite and the consequences of such events. The MHI assessment is not an isolated activity but is an integral part of an overall risk management strategy. We have trained professional staff with over 20 years of experience within the major hazard installations (mhi). 

Our inspection body is accredited to the South Africa National Association for Standards (SANAS) and the Department of Employment and Labour.

To support the implementation of this approach, we use the SANS1461 standard for quantitative risk assessments in Major Hazard Installations. We use the state-of-the-art software for consequence modelling and risk calculations.  The software which is used for the MHI assessments are Gexcon-TNO Effects and Risk Curves, to assist in producing and managing risk data and to facilitate risk-based decision-making.

Uses of the Major Hazard (MHI) Risk Assessment include:

  • corporate insurance risk reduction, 
  • compliance to local and national regulations to obtain a licence to operate,
  • estimating risk levels and assessing their tolerability,
  • identifying main contributors to risk,
  • demonstrating acceptability of risks to regulators and the workforce
  • evaluating risk reduction measures to determine effectiveness in reducing risks
  • identifying safety and environmental critical equipment and procedures
  • providing a basis for ongoing decision making on safety and operational issues
  • development of the onsite and offsite emergency plan,
  • development of a process safety management system, 
  • safety awareness training for employees, 
  • community discussions with regards to the impact on society
  • planning development for sites around the facility e.g hospitals, schools, recreation areas,
  • input into the environmental impact assessment.

​The major hazard installation  risk assessment or  MHI assessment is required by the Major Hazard Installation (MHI) Regulations as part of the Occupational Health and Safety Act and Regulations 85 of 1993.  Companies which receive, store, process or manufacture hazardous chemicals, MAY require a MHI risk assessment. The sectors which may require a MHI risk assessment are :

  • Oil and Gas Industries
  • Petrol stations
  • Chemical manufactures
  • Warehouses storing hazardous chemicals
  • Paper/Pulp mills.
  • Plastic manufactures
  • Paint manufacturers
  • FMCG industries
  • Mining industries
  • New developments 
  • Environmental Impact Assessment (EIA) 
  • Local authorities for land planning 
  • Emergency response teams

The common hazardous chemicals which will need to be evaluated are in the following groups :

  • Flammable liquids - e,g diesel, petrol, jet fuel 
  • Flammable gases - e,g LPG
  • Toxic gases - e.g Chlorine, Ammonia, Sulphur Dioxide
  • Toxic liquids
  • Corrosive chemicals - e.g Sulphuric acid
  • Explosive chemicals - chemicals which can explode if it becomes unstable
  • Oxidising chemicals - e.g hydrogen peroxide.

We produce thorough, efficient and cost-effective MHIs in a format that provides the following benefits:

  • easy use of MHI risk assessment data in ongoing decision-making
  • developing the MHI risk assessment as a through-life record of an asset
  • managing, recording and auditing the MHI assessment risk data.

Who are Authorised to conduct an MHI Risk Assessment?

​​To conduct a major hazard installation risk assessment or MHI assessment which will comply with the regulations, a service provider has to be registered with the Department of Employment (DEL) and Labour. The service provider must also be registered with SANAS as an Approved Inspection Authority MHI (AIA).  An Approved Inspection Authority MHI (AIA), is an organisation that has gone through a series of gates to implement the ISO 17020 standard within the organisation. The ISO 17020 system is the management system by which the approved inspection body MHI AIA is governed. The approved inspection authority (MHI AIA) must show technical competence in the field of the Major Hazard Installations (MHI) . The approved inspection body (MHI AIA) must have the relevant qualifications and the experience in the hazardous or dangerous chemicals environment. 

MHI Risk Engineers are registered with the Department of Employment and Labour (CI MHI 0015) and with SANAS as an Approved Inspection Authority for the Major Hazard Regulations (MHI AIA). MHI Risk Engineers are able to provide your organisation with a legal compliance certificate, which will lead to a licence to operate been issued by the local authorities.
