  • BS EN 54: Fire detection and fire alarm systems,
  • ISO 16530-1: Petroleum and natural gas Industries – Well integrity for operations on or offshore, etc. 

Significance of undertaking F&G Mapping?

  • F&G Mapping permits the designer to position flame and gas detection devices at intervals within the facility and assess the coverage afforded by the system. This can be mechanically correlative against pre-specified targets that the system should achieve.
  • F&G Mapping provides designers with the methodology and tools to review detection coverage against pre-determined targets, and guarantee that an appropriate and optimized system is commissioned.

F&G mapping software’s that are commonly in use are:

  • PHAST (Process Hazard Analysis Software),
  • FLACS (Flame and Gas Modeling Software),
  • DNV GL G-FETT (Gas Fire and Explosion Tool),
  • SMOKEVIEW, Fire Dynamics Simulator (FDS),
  • ANSYS Fluent, and Safeti (Quantitative Risk Assessment Software). 

The key objectives of a Fire and Gas Mapping Study include: 

  • Hazard Identification: Identifying potential fire and gas release scenarios that could occur within the Facility. This includes assessing process operations, equipment, storage areas, and other potential sources of ignition or gas leaks. 
  • Consequence Analysis: Evaluating the consequences of potential fire and gas release scenarios, including the extent of fire spread, dispersion of hazardous gases, and potential impact on Personnel, Environment, and Assets. 
  • Fire Detection and Protection Analysis: Assessing the effectiveness of existing fire detection and protection systems, such as fire alarms, fire suppression systems, and fireproofing measures. 
  • Gas Detection and Monitoring Analysis: Evaluating the coverage and performance of gas detection systems used to monitor and detect the presence of flammable and toxic gases in the Facility. 
  • Mapping of Hazards and Response Zones: Creating visual representations (maps) of the Facility to indicate areas with potential fire and gas hazards and identifying response zones for emergency management. 
  • Risk Assessment: Quantifying the level of risk associated with various fire and gas scenarios and prioritizing risk reduction measures. 
  • Recommendations: Providing recommendations for improving fire and gas safety, such as the installation of additional fire and gas detection systems, the enhancement of existing systems, or the implementation of new safety protocols. 

Typically, Process Engineers, Safety Engineers, Fire Protection Specialists, and other relevant stakeholders collaborate on this study. By conducting a Fire and Gas Mapping Study, Industrial Facilities can improve their safety measures, reduce the likelihood of incidents, and safeguard Personnel, Assets, and the surrounding environment more effectively in the event of a fire or gas release. In high-risk Industries, it is an essential component of a comprehensive safety management system.
