People Also Ask (FAQ)

What is a Major Hazard Installation in South Africa?
In South Africa, a Major Hazard Installation (MHI) is any industrial facility that stores, processes, or handles hazardous substances in quantities and conditions that, if a loss of containment occurs, could pose a significant risk to the health and safety of employees and the public outside the facility boundary.
Who enforces MHI regulations in South Africa?
The Department of Employment and Labour (DoEL) is the primary regulatory body enforcing MHI regulations under the Occupational Health and Safety Act, 1993.
What changed in the MHI Regulations 2022?
The 2022 update introduced a staged compliance approach, mandatory licensing for high-hazard establishments, stricter requirements for designating a competent Responsible Person, and mandatory alignment with SANS 1461 for risk assessments and SANS 1514 for emergency planning.
What is the penalty for MHI non-compliance?
Under the 2022 Regulations, failure to comply with MHI obligations is a criminal offence. Penalties can include severe fines ranging from ZAR 500,000 to ZAR 5,000,000, imprisonment for up to 24 months, and immediate operational prohibition by inspectors.
How often must an MHI risk assessment be renewed?
In South Africa, an MHI risk assessment must be comprehensively reviewed and resubmitted at least every 5 years. However, immediate updates are required if there is a significant change in the quantities of substances stored or if a process modification alters the site's overall risk profile.
