I'm not so concerned about the pain - it's eased now.
I'm more interested in knowing how this can happen. I thought LPG systems were pretty much fail-safe. How can LPG pass from the storage tank through the pump and metring systems even though the unit was switched off? It's like walking into a closed petrol station and picking up a pump nozzle and just spraying a burst of petrol around.
Doesn't the cashier have to activate a pump? And what would cause the seal on the nozzle to fail at the same time?
