Abstract
A gas line safety evacuation apparatus and method wherein earthquakes or other hazardous disruptive events are monitored and detected. Upon detection of an earthquake or like event, gas or other fluid lines are evacuated by an evacuation pump, and the evacuated gas is stored in a storage tank for future use. Control valves are activated upon detection of the earthquake to prevent additional gas or fluid from entering the lines.
