Would a walk in cooler require the 18 inch clearance around the walls? when the racking is high enough to allow cleaning of the floors and walls?
SQF Element 11.6.2 Cold Storage, doesn't specify.
11.6.2.1 The site shall provide confirmation of the effective operational performance of freezing, chilling, and cold storage facilities. Chillers, blast freezers, and cold storage rooms shall be designed and constructed to allow for the hygienic and efficient refrigeration of food and be easily accessible for inspection and cleaning.
Thank for the help.
