Introduction
A Fire & Gas (F&G) Mapping Study is a critical component of functional safety engineering, primarily used in high-risk industries such as oil & gas, petrochemicals, LNG, and power generation. The objective of an F&G Mapping Study is to assess the optimal placement and effectiveness of fire and gas detectors to ensure early detection, minimize risks, and meet performance targets defined in Safety Integrity Level (SIL) studies and corporate HSE standards.
Objectives of F&G Mapping
The primary goals of an F&G Mapping Study include:
• Ensuring Adequate Coverage: Identifying detector locations that provide maximum area and volume coverage.
• Optimizing Detector Quantity: Avoiding over-design while ensuring sufficient redundancy and functional reliability.
• Compliance with Standards: Meeting international safety standards like IEC 61511, NFPA 72, and ISA TR84.00.07.
• Evaluating Detection Performance: Quantifying detection coverage using tools and models to validate detector layout against defined risk scenarios.
Protocol
