The following good practice is recommended:
- Cleaning chemicals used for cleaning coolrooms should only be used in concentrations and contact durations, as prescribed by the chemical supplier. In any event, the concentration of the cleaning solution should not exceed 5%.
- Soft nylon bristle brooms coupled with water pressures of less than 400psi (2760kPa) is recommended.
- Regular inspection of slip joints and the general detailing of the coolroom will highlight problems before they become major concerns.
- Monitoring of sealant performance at the base of the panel is critical to prevent water ingress.
- Once moisture has entered the panel, it will expand when frozen, causing the panel to bulge. This causes the seals to be broken and moisture-laden air to enter the panel, causing the panel to bulge further, greatly diminishing the efficiency of the coolroom.
- Bulging of panels could indicate that moisture has entered the panel through the following means.
- a poorly sealed slip joint
- a gap that has developed between the bottom channel and the panel
- a panel has been punctured by for example forklift tines.
- Consideration should be given to means of preventing damage to coolroom walling incurred whilst handling stock stored within and around the coolroom.
