Inerting
To ensure a non-flammable condition during subsequent gassing-up with cargo
Oxygen concentration reduced from 21 per cent to a maximum of five per cent by volume
Chemical gases, such as vinyl chloride or butadiene, levels of oxygen as low as 0.1 per cent required to avoid a chemical reaction with the incoming vapour
