Do you have ARR approval for you dunnage bags ?

Why i can not place a dunnage air bag on the container door ?
Because this is very dangerous for those who open the container at arrival. The cargo might have shift a little towards the doors and put enormous pressure to the bags. The doors can “explode” when opening and hurt people.
The average ( working ) pressure is around 0,05 bar. That is usually high enough to secure the cargo.
The max. filling pressure indicates how much the bag maximal can be filled. According to the international shipping safety regulations the burst pressure has to be 3 times higher than the maximum filling pressure for light and medium bags, and 2 times higher for heavy and super heavy bags.
