I have a cousin that works at a petrochem plant. He told me that all the “common trips” never really happen since they’ve been drilled on how and what to do and how to prevent them, but the second shit really does go down you better have a senior around that has seen that specific trip before. Especially considering there’s tens/hundreds of thousands worth of produce being burned off by the second until things are back under control.
Even if you need Id/scanner. If the check is at the elevator on the ground floor it may often as well not exist.
