Apply the technique Present state/ Desired State & Duncker Diagram for this problem:

Sodium azide is used the propellant in air bag system. This chemical is mixed as an with an oxidizing agent and pressed into pellets, which are then hermetically sealed into a steel or aluminum can. Upon impact, ignition of the pelletized sodium azide generates nitrogen gas that inflates the air bag. Unfortunately, if the sodium azide con- tacts acids or heavy metals (e.g., lead, copper, mercury, or their alloys), it forms toxic and sensitive explosives. Consequently, at the end of an automobile's life, a serious problem surfaces when an automobile with an undetonated air bag is sent to the junk-yard for compacting and shredding, because it might contact heavy metals during this process. The potential for an explosion during processing represents a serious danger for the people who operate the scrap recycling plant. Apply two or three problem defi- nition techniques to this situation
