A recent incident in a plant due to power failure caused a safety valve to pop and release toxic chemical to the atmosphere. The residents around the plant complained. The safety valve discharged to a vent stack. Check where your safety valves discharge. Even though the codes allow discharge to atmosphere in certain cases, the weather conditions at the time of discharge can never be predicted and dispersion modelling can never be 100% accurate.
