Respiratory therapist must ensure that any oil or dust is cleared from high-pressure medical gas delivery systems before pressurization. why is this action needed

The compression of the gases is a type of adiabatic process. These adiabatic processes can result in the rise of the temperature.

The oil or dust particles present in the gas mixture can cause the ignition of the gases.

In case, the oil and gas particles are not removed from the system, then it can cause fire and an accident may occur. So, it is important to remove oil and dust from the system.
