How sad, I just heard of this and the loss of a student. Condolences!!!

You may all already know to be careful, but we also experienced an explosion at our "private" rental on Nevis, in 2008. The landlord blamed on our carelessness but we weren't doing anything different than any other day. Fortunately ours only blew the door off the stove and nobody was nearby.

Have your stoves/etc. checked.
