## Narrative

While preparing to replace patch on acid storage tank, a rapid energy release out of the vent line caused the line to burst, causing unexpected release of acid to spray through the deaerator on top of the tank. During the action of grinding the sparks were going towards the overflow pipe which caused an ignition due to the high amounts of hydrogen.
