HAMPSTEAD, NH - Hampstead firefighters were called out for a leaking 150 lb. propane tank on the warm spring day of April 27th. The tank had been filled earlier in the cooler morning. Due the the tank being in the hot sun all day the relief valve opened. When fire crews got on scene the tank was venting product, so a hand line was stretched, water was applied to the tank and firefighters were able to reset the valve.
