Gas & Flame Detector Placement and Quantity Engineering
Performance-Based Fire & Gas System Design
Effective fire and gas detection starts with engineered design.
Our Gas and Flame Detector Placement and Quantity services use ISA TR84.00.07:2018 methodologies to deliver performance-based fire and gas system designs. Through hazard and risk assessments, 2D plot plans, and advanced 3D mapping, we optimize detector placement to protect people, property, and operations while controlling costs.
Engineering Beyond Prescriptive Codes
While standards such as NFPA and ISA provide essential guidance, complex facilities handling combustible and toxic gases require deeper analysis.
Our approach includes:
- Hazard and risk scenario assessment
- Codes and standards review
- Matching detection technologies to process hazards
- Coverage target definition
- Mitigation effectiveness evaluation
The result is a defensible, risk-based design aligned with industry best practices.
Service Offerings
Site Survey
For facilities without updated 3D models or P&IDs, our engineers conduct on-site evaluations and provide:
- ISA TR84.00.07 Hazard & Risk Summary
- Code and best-practice review
- Detector placement recommendations
- Alarm set point and control action guidance
- Optional 2D plot plan
ISA TR84.00.07 Effectiveness Study
Structured qualitative and semi-quantitative analysis to determine optimal detector quantity and placement.
Deliverables include:
- Hazard & Risk Summary
- Coverage targets by hazard area
- Recommended detector technologies
- Alarm set points and control actions
- Optional Risk Reduction Factor calculations
3D Mapping & Optimization
Using facility 3D models, we:
- Optimize detector placement to meet coverage targets
- Refine x, y, and z coordinates
- Compare baseline vs. optimized layouts
- Improve control strategies, including voting logic
This reduces unnecessary devices while maintaining protection performance.
Designed For High-Risk Industrial Environments
Ideal for oil and gas, chemical processing, LNG, power generation, and manufacturing facilities managing flammable or toxic gases.
If your facility handles hazardous gases, optimized detection is a critical layer of protection.
