Members of the Haz Mat Unit made their way into the apartment and were presented with a home therapy tank actively leaking, creating a high oxygen atmosphere. Crews quickly removed the cylinder to the outside and had the Ladder crew ventilate the area to bring levels back down to normal conditions.
Once on the outside, members assessed the cylinder and found a relief valve stuck partially in the open position. The Haz Mat team reset the valve to stop the leak and requested the responsible party to respond out and remove the cylinder from the property.
