We are transferring raw materials from low care to High risk. Instead of building in a traditional chemical sanitiser belt are implementing ozone. 

 

Product is being transferred via a conveyor into a high risk fridge then in the evening once production have left the whole area receives ozone. 

 

Now we have identified it as a CCP to take raw materials into HR, what would be the critical limits for Ozone, would it simply be ozone working or not eg target green light not illuminated after the cycle?

 

Thanks

With sanitizing agents you typically need to meet some minimum of concentration and duration.  If you could find a gas analyzer that could be programmed to take samples every X minutes that could do the trick, you'd need to validate what the target values are first though.
