2.5.1 Roof Entry
The information in this section applies to entry through the bin roof only.
• Never enter a bin from the roof if you don’t know its unloading history. Bridges of stored
material can form above a void space below, causing potential for entrapment.
• Have body harness tethered to a lifeline controlled by two others outside the bin. One
worker should be able to see inside worker through the inspection hatch. If there is an
accident, one worker can focus on the victim while the other goes/calls for help.
• In the event that you are trapped in the bin as it is unloading, move as quickly as possible
toward the bin wall; keep yourself elevated above the material by walking on the flowing
mass while staying as close as possible to the bin wall.
2.6. Smoothwall Bin Emergency Entry
In an emergency situation:
• Follow protocols set by your local occupational safety and health agency.
• If you need to rescue somebody inside the bin, call emergency responders and only attempt to rescue using
non-entry rescue procedure/equipment. Do not enter the bin unless you are trained for rescue, equipped and
relieved.
2.7. Smoothwall Bin Entrapment
It takes more than 1000 lb (4.5kN) of force to remove someone buried below the surface.
The following sections cover common ways a person gets submerged or trapped:
2.7.1 Flowing Grain
This procedure may also apply to fertilizer where the bin is intended for fertilizer storage.
• Grain flows in a funnel-shaped path when unloading. This vortex of grain behaves very much like a water
drain. Velocity increases as grain flows from the bin wall at the top of the grain mass into a small vertical
column at the center of the bin.
• Flowing grain will not support the weight of a person. Submersion happens within seconds.
