Major Hazard Facility Support

In 2018, 4Sight helped our Major Hazard Facility (MHF) clients with moving toward compliance. We helped with emergency response planning, safety case documentation, major accident prevention policy (MAPP) documentation, qualitative and quantitative risk assessment, consequence modelling, and general health and safety compliance.

We used BREEZE and ALOHA to model consequences of MHF events, such as explosions and chemical releases. We also used air and hydrological modelling programmes to map chemical plume dispersion. We also facilitated HAZOP, Hazard ID, and qualitative risk assessment workshops, assisted with worker and public engagement and provided support for meeting with regulatory and emergency response agencies.

For one MHF, we provided consequence modelling, which helped form the basis for the emergency plan we developed for the facility. The plan was presented to the New Zealand Fire Service who stated that it was the most comprehensive and one of the best emergency response plans they had ever reviewed. We also assisted the client with validating a no-cost solution to separation distances for hazardous substances, assisted with the Safety Case, developed plans and procedures, and assisted with consent compliance. We also developed a Permit to Work system and provided training to workers and contractors. In addition, we worked with the client to develop reports provided to EPA and WorkSafe demonstrating that the facility could be operated safely.

At another MHF, we conducted bow tie and layers of protection analysis evaluations to identify the highest consequence potential outcomes and controls required to prevent or mitigate incidents. We also conducted consequence modelling and assisted with their emergency response plan and a WorkSafe audit.

For a lower-tier MHF, we provided consequence modelling and teamed with Olsson Fire & Risk to develop a fire study to demonstrate that the fire systems were adequate to meet regulatory criteria.
