Hole Size (The size of the leak or emission source — larger holes release more flammable material)
Large (=5mm)
Medium (2–4mm)
Small (=2mm)
Operating Pressure (Higher pressure can lead to faster, more forceful gas release)
High (=10 bar)
Medium (2–9 bar)
Low (=2 bar)
Ventilation Quality (Describes how ventilated the area is — outdoor reduces risk)
Minimal (Indoor/Confined)
Moderate (Partially Open)
High (Outdoor, Good Wind)
Obstacles & Confinement (Barriers and confined spaces trap gases and increase risk)
High Obstruction
Some Obstacles
Free Movement
Time Spent by Personnel (More time in the area increases safety precautions required)
