Smoke and Gas Ingress Analysis (SGIA)

Go to Formal Safety Assessment
Smoke and Gas Ingress Analysis (SGIA) evaluates the potential for smoke and hazardous gases to enter critical areas like temporary refuges, control rooms, or shelters during an emergency. This analysis helps identify vulnerabilities in ventilation systems and structural barriers, ensuring these areas remain safe and habitable for personnel during emergencies.

Importance of SGIA

1. Protects Personnel
  • Ensures safe environments in critical areas during emergencies.
2. Enhances Emergency Preparedness
  • Identifies and mitigates risks of smoke or gas infiltration.
3. Supports Compliance
  • Meets safety standards and regulatory requirements.
4. Reduces Downtime
  • Minimizes operational disruptions caused by emergency scenarios.

Key Steps in SGIA

1

Define Assessment Scope
Identify critical areas to be analyzed, such as control rooms or temporary refuges.

2

Identify Ingress Pathways
Evaluate potential routes for smoke or gas entry, such as doors, ventilation systems, and structural gaps.

3

Simulate Emergency Scenarios
Use modeling tools to simulate fire or gas release scenarios and their impact on air quality.

4

Analyze Ventilation Systems
Assess the capability of HVAC systems to prevent or control smoke and gas ingress.

5

Evaluate Impairment Risks
Determine how ingress could impair safety-critical areas and affect personnel.

6

Develop Mitigation Strategie
Recommend improvements, such as enhanced sealing, filtration systems, or improved ventilation designs.
