I'm asking for opinions. My company owns a site in a different state and I'm in the process of getting them SQF certified. Are dock door curtains required? I've never worked anywhere that didn't have them. We have a quote for 7K to get them installed and I'm wondering if the expense is required. There is an awning extending from the roof and that is it. No other shelter when unloading and loading trucks. Birds could easily fly into the building, rain, etc. Comments are appreciated!
