Hopper Entry
Normal use of the hopper and routine maintenance do
not require entry. Ladders are provided in the hoppers,
but they are for emergency egress, and are not intended
for routine entry. However, do not remove the ladders, as
they are also pressure-balancing vent lines.
▲ A hopper that is full or merely appears full can be an
entrapment hazard. You can sink entirely into the grain, or
into a void, and suffocate in a matter of seconds. Grain
bridges and crusts are especially dangerous.
▲ You can be overcome by hazardous fumes very quickly even
in an empty hopper with the lid open.
▲ A partially full hopper, even with no bridging present, is a
suffocation risk.
Oxygen levels may be insufficient and/or
dust levels may be too high for breathing.
▲ Do not enter a hopper for loading material.
▲ Do not enter a hopper for unloading material.
▲ Do not enter a hopper for routine cleaning.
▲ Do not enter a hopper for any meter maintenance.
▲ Never enter a hopper without at least one trained and
equipped attendant present.
▲ Never enter a hopper for any reason unless you fully
comply with applicable laws, regulations, rules,
agreements, and the instructions in this section. Where
applicable laws, regulations, rules, agreements contradict
an instruction below, do not follow that instruction.
Depending on their use, the ADC2350/E and
ADC2350B/BE material hoppers may be or become
“permit-required confined spaces” under U.S. OSHA
regulations (29 CFR 1910.146) and similar regulations,
statutes, insurance agreements and local business
policy. A written policy and permitting process may be
required for any hopper entry.
Hopper entry may be necessary in some unusual
circumstances, such as:
• hopper level sensor replacement; or,
• removal of obstructions too difficult to pull out with the
meter box removed and not susceptible to fishing or
pumping out from the open lid.
Rapid Suffocation Hazard:
Encrusted grain may be loose and flowing beneath the crust.
Any hollow spaces are highly likely to have insufficient oxygen
and/or toxic gases from microbial action. Falling through a
crust in either case can result in death in a matter of seconds.
Never enter a hopper to dislodge a crust or bridge.
