in the stories i hear its usually not the lock out mechanism that fails, its always an obstruction. the door works fine but swings outwards and someone parks a pallet in front of it or someone damaged the foot of a shelf with a jack/dolly loading product into the freezer then the little old grocery lady goes in to get something for a customer and the rack collapses behind her dumping a literal ton of ben and jerries between the door and her.
