When all equipment and materiel is stored on stationary side of shelter, limited
floor space presents a safety hazard to operating personnel. This is most critical
during raising and lowering of roof panel. Failure to observe supplemental
instructions could result in SERIOUS INJURY to personnel. Personnel inside
shelter could become trapped between roof panel and equipment bolted to floor.
2. Two personnel outside shelter must lift roof panel (1) far enough to allow two people inside to release two
support struts (2), extend them to full length, and insert quick-release pin.
