Under IGF Code, what is the lower flammability limit (LFL) threshold to trigger Emergency Shutdown (ESD)?
Direct Answer
Option C: 20% LFL in gas fuel preparation rooms or ducting
The IGF Code requires an Emergency Shutdown (ESD) to be triggered when gas concentration reaches 20% of the Lower Flammability Limit (LFL) in gas fuel preparation rooms or ducting. This safety threshold provides a critical buffer, ensuring that fuel supply is isolated well before an explosive atmosphere can develop.
