<p>A method of sterilisation, sanitisation and/or decontamination comprising a catalyst conditioning phase and a subsequent decontamination phase, the catalyst conditioning phase comprising directing a substantially dry inert gas through an ozone depletion catalyst 70 and the subsequent decontamination phase comprising the steps of producing a humidified enclosed environment; discharging ozone into the humidified environment; maintaining the ozone and water pressure levels at a concentration that will achieve the required degree of decontamination and sterilisation of the humid environment; and passing the substantially decontaminated and sterilised environment through the catalyst 70 to reduce the concentration of ozone to a predetermined level. The inert gas may be air, and a hydrocarbon containing a carbon-carbon double bond may be introduced into the environment to aid removal of the ozone. A method for increasing the life of an ozone depletion catalyst is also disclosed.</p> |
