Dangers Related To Cryogenic Gases

By Stephen Hamilton


There are certain hazards which are associated with one working with low-temperature liquefied gases. Most of these are cryogenic gases which include nitrogen, oxygen, argon, carbon dioxide and helium. One using them is required to take proper precaution for their safety and that of their neighbours. They are mostly liquefied to reduce their volumes and make it possible to store them in vessels. The discussion below explains much about them.

Starting with inert gases including helium, argon, and nitrogen, they are known to be dangerous when exposed to the environment in large quantities. They lead to a reduction of oxygen after which causes suffocation to the individuals who inhale them. In case one inhales huge amounts, there are risks of death since they will shut down the respiratory systems.

On the other hand, there is carbon dioxide which is another gas which has the same effect as the ones discussed above. But, the effects related to carbon dioxide are lesser toxic as compared to that of inert gases. Also, it is important to note that it has greater effects on the atmosphere when in large quantities. It leads to global warming through what is called greenhouse effect.

Oxygen is of great significance to respiration. All organisms use it for survival and need to keep clean and sufficient for use. But on the other hand, when in excess in the atmosphere, it can cause to increase combustion cases. Reason being, it has the characteristics of raising the rates of burning. Hence, it enhances burning of materials which do not readily burn on open air.

When it comes to dealing with liquid oxygen condensation, there shall be a great need to know that liquid nitrogen and helium can assist much. They are cold enough to enhance condensation of oxygen from the air. This has a high potential for increasing the chances of combustion. That is why it is recommended that vessels with these components should be kept away from combustible materials.

Another issue to consider is an effect of the liquefied substances on your health. When one encounters with cold surfaces, there is the tendency of your skin having cold-burns. Also, when you stay in a place which is extremely cold, there is the possibility of suffering from asthma. The same might happen when one is handling the liquefied gaseous materials. So, one should be in safe clothing which will protect them from such effects.

When the gaseous materials are being stored in the vessels, it is essential for the experts and the systems involved to have the capabilities of detecting the required amounts. There should be no cases of overfilling the cylinders since it can lead to leakage. So, there must be valves which will enhance release of excess amounts. Afterwards, they should be seals appropriately before they are kept in respective places.

Lastly, it is worth noting that careless handling of each one of these gaseous contents can lead to severe effects on one health and life. Therefore, one should take precautions and measures to make sure that their safety is guaranteed as well as that of those around them. One ought not to ignore the set precaution measures at any one given time.
