how can you prevent entry of air ( CO2) into the bottle?

To prevent this, multiple cylinders should be used when large amounts of CO2 are needed, or the cylinder can be heated with warm water (maximum 50°C). The cylinder should never be heated with a flame.
Answer:
CO2 flooding system or central bank CO2 system is one of the common fixed fire fighting system installed on most of the ships. It releases carbon dioxide (CO2) in bulk quantity to a protected space (such as engine room, cargo hold, purifier room, pump room, etc.) under fire.
Why CO2 is used?
Carbon dioxide is the fire extinguising medium used in CO2 flooding system. It is an effective fire suppression agent applicable to a wide range of fire hazards. It has a high rate of expansion which allows it to work fast. When applied to a fire, CO2 provides a heavy blanket of gas that reduces the oxygen level to a point where combustion cannot occur
There are several advantages for the CO2 as a fire fighting medium. They are:
Density is 1.5 times higher than air. So CO2 settles down and displaces air.
It can be easily liquefied and bottled.
20% – 30% CO2 concentration extinguishes fire by smothering
Non-corrosive
Non- conductor of electricity
No residues left after application
No deterioration with age
Similarly there are some disadvantages also, such as:
CO2 is highly asphyxiating. 9% concentration causes unconsciousness within minutes
Very little cooling effect. So there is danger of re-ignition.
When discharged, solid CO2 particles present and generate sufficient static electricity to produce spark.
