17. Return to the roof via the roof access system located on the roller end of the FPU-8 to tighten the
upper horizontal interconnectors.
Fall hazards that may cause injury or death exist when climbing onto, returning from or
working from the top of the container. Always maintain three points of contact (two feet
and one hand, or one hand and two feet) with the folding steps and roof access handle
when climbing onto the ASLMS container. All movement should be in the forward
direction. Never move, step, or walk backward when working on top of the system. A fall
can occur if a worker loses concentration and steps backward off the edge. Stand erect
only if necessary, and only away from the edge. Working from a kneeling position helps
reduce the threat of a fall. Access to roof by forklift or other MHE is forbidden.
18. When the FPU-8/12 containers are mated and the horizontal interconnectors are seated, using a
9/16-inch hex socket, 2-inch long extension and -inch square drive flex head wrench, tighten the
locking bolts opposite each other, in a balanced sequential pattern. Tighten until all four horizontal
interconnectors are tight and seated. Tightening sequence example:
19. Repeat tightening sequence several times until there is no more bolt movement. Ensure that all four
horizontal interconnectors are sufficiently tightened prior to the next steps.
