## Why Laboratory Compressed Gas Cylinder Safety Essentials Matters

Compressed gas cylinders combine several potential hazards.

The pressure inside a cylinder can be extremely high. If a cylinder is damaged, improperly secured, or subjected to unsuitable conditions, the stored energy can create serious risks.

The gas itself may also introduce additional hazards.

Depending on the substance, compressed gases may be:

* Flammable
* Oxidising
* Toxic
* Corrosive
* Asphyxiating
* Reactive
* Inert
* Environmentally hazardous

A release can therefore create risks ranging from fire and explosion to toxic exposure or oxygen deficiency.

The **Laboratory Compressed Gas Cylinder Safety Essentials** course helps learners understand these hazards and develop safer habits when working with compressed gas cylinders.
