Why should compressed gas tanks not be left in median areas?

Compressed gas tanks should not be left in median areas primarily because they pose significant safety risks in the event of a collision. If a vehicle were to strike a compressed gas tank, it could turn the tank into a projectile due to the high internal pressure. This can lead to not only damage to the vehicle but also potentially severe injury to individuals in the vicinity.

Moreover, many compressed gases can be shock sensitive, meaning that they might react or even detonate if subjected to sufficient impact or force. This risk of detonation would pose an immediate danger to workers and motorists alike, creating an unsafe environment within the work zone.

Therefore, to ensure the safety of everyone in and around a work area, it is critical to keep compressed gas tanks away from median areas where they may be vulnerable to collisions. This combined understanding of the projectile risk and the potential for detonation highlights the importance of proper handling and placement of compressed gas tanks in work zones.
