I always thought that refrigerated units had to have internal emergency release handles to prevent being locked in?
Still good you where their to save the day

Well done. I hope the Mog got a pat on the bonnet too.
I don't know about UK law but walk in freezers in Australia must have an internal door release. I imagine this applies to freezer vans and trucks too. Too easy for something like this to happen.
