Abstract: A lightweight barrier insert door is attached to an enclosure, such as a shipping container that holds a product to be fumigated, such as during transport of the product to a new location. The barrier insert door fits within the doorway of the container to provide a sealed barrier to mitigate leakage of a fumigant from the interior of the container. The barrier also includes air intake ports to maintain the structural integrity of the container and to provide ambient air to the interior. Additional ports allow for connection for fumigant entry, monitoring, and/or an exhaust hose to be connected to or through the barrier for the fumigation process. The barrier can be height adjustable to account for shipping containers of various sizes and can be connected with fumigant exhaust and release systems for the safe release thereof.
