It is clear in the oil and gas industry that large combustible gas releases can have catastrophic consequences. To prevent this, fire and gas safety professionals select and analyze a diverse set of representative release scenarios, considering such factors as duration, orientation and type of gas.1 Understanding the hazard potential is a vital step in selecting sensors that are most suited for gas detection. Despite such efforts in the original safety assessment, the capacity of an instrument to detect significant leaks is often inferred from its performance with small ones. As such, the instrument’s behavior under probable release scenarios is not well understood and generally leads
