Hopper Lid Safety Information
Entrapment and Rapid Suffocation Hazard:
Never enter a hopper for loading, unloading or routine main-
tenance. Leave strainer in place except when instructed to
remove it. Keep lid tightly closed during operations. Keep lid
locked closed or, during storage, locked slightly open. Store
ladder to discourage access to lid area. Keep children away
from drill.
▲ A hopper that is full, or merely appears full, can be an
entrapment hazard. You can sink entirely into the grain, or
into an oxygen-deficient void, and suffocate in a matter of
seconds. Grain bridges and crusts are especially danger-
ous.
▲ When hazardous fumes or low oxygen levels are present,
you can be quickly overcome even in an empty hopper with
the lid open. There may be no odors to alert you to the haz-
ard.
Avoid metering problems caused by air leaks. Air leaks can
cause irregular metering of materials. Check lid seals for dam-
age at frequent intervals. Check that latch closes lid tightly.
Keep lids closed. Keep tightly closed for operations.
Keep loosely closed for storage. Open only for material
loading, hopper clean-out and exceptional maintenance.
