What is the primary hazard of compressed gas cylinders?

The primary hazard associated with compressed gas cylinders is that they can explode if not handled properly. This risk arises from the immense pressure contained within these cylinders. If a cylinder is damaged, improperly stored, or subjected to high temperatures, it can lead to a rapid release of gas. Such a release can cause the cylinder to become a projectile or result in an explosion due to the rapid expansion of gases, which could lead to serious injury or damage.

While leaking toxic gases, corrosion of materials, and unintended chemical reactions are important safety concerns in handling hazardous materials, they are secondary hazards in the context of properly managed compressed gas cylinders. The explosive risk is critical to recognize, as it emphasizes the need for training in safe handling practices, regular inspections, and adherence to storage guidelines to prevent catastrophic incidents.
