7 Ctr C

What is the procedure to open the floor hatch to put equipment in the basement

This is very difficult to arrange since it's in the prisioner sally port. TECO has done it using a fork lift in the past. We discurage it's use and should be a last resort if for some reason equipment can't be disassembled and brought down the stairs.
