Abstract: A multi-component container has a non-rigid, durable, flexible design constructed with a tough outer bag having specifically located fastenings. The outer bag when assembled with the fastenings constrains an inner bladder that is a durable, flexible, sealable leakproof bag having dimensions selected relative to the outer bag. The combination of the inner and outer components enable the container to meet or exceed national and international testing criteria applicable to the transport of many hazardous items in accordance with applicable regulations. A related method of transporting is also disclosed.
