Confined Space
With materials loaded, or once used for hazardous
fertilizers, or seeds with hazardous treatments, your
fertilizer hopper may become a
“permit-required confined space”
under applicable statutes, regulations, insurance rules or
business policy. The vent tube structure in the hopper
has features to assist escape, and is not for routine entry.
▲ A hopper that is full or merely appears full can be an
entrapment hazard. You can sink entirely into the material,
or into an oxygen-deficient void, and suffocate in a matter of
seconds. Fertilizer bridges and crusts are especially
dangerous.
▲ When hazardous fumes are present, you can be quickly
overcome even with the hopper lid open.
▲ Do not enter a hopper for material loading, material
unloading, hopper cleaning or meter maintenance.
▲ Clean hopper by power washing from outside hopper top.
▲ Perform meter maintenance by removing meter from bottom
of empty hopper.
▲ If obstruction removal or repair requires hopper entry, have
the work performed by a team trained in confined space
procedures. See “Hopper Entry” on page 37.
Practice Safe Maintenance
▲ Understand procedure before doing work. Use proper
tools and equipment. Refer to this manual for additional
information.
▲ Work in a clean, dry area.
▲ Lower the planter, put tractor in park, turn off engine, and
remove key before performing maintenance.
▲ Make sure all moving parts have stopped and all system
pressure is relieved.
▲ Allow planter to cool completely.
▲ Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on planter.
▲ Inspect all parts. Make sure parts are in good condition
and installed properly.
▲ Remove buildup of grease, oil or debris.
▲ Remove all tools and unused parts from planter before
operation.
