Safety Guidelines
Safety guidelines are general-to-specific safety rules that must be respected at all times in the grain storage environment.
Our foremost concern is your safety and the safety of others associated with grain handling equipment.
This manual is to help you understand safe operating procedures and some problems that can be encountered by the operator and other personnel.
As owner and/or operator, you are responsible to know what requirements, hazards, and precautions exist
and inform all personnel associated with the equipment or in the area. Avoid any alterations to the equipment. It can produce a very dangerous situation, where SERIOUS INJURY or DEATH can occur.
This equipment shall be installed in accordance with the current installation codes and applicable regulations, which should be carefully followed in all cases. Authorities having jurisdiction must be consulted
before installations are made.
You should consider the location of the bin site relative to power line locations or electrical transmission
equipment. Contact your local power company to review your installation plan or for information concerning
required equipment clearance. Clearance of portable equipment that can be taken to the bin site must also
be reviewed and considered. Any electrical control equipment in contact with the bin must be properly
grounded and installed in accordance with National Electric Code provisions and all local codes.
This product is intended for the use of grain storage only. Any other use is a misuse of the product.
This product has sharp edges, which may cause serious injury. To avoid injury,
CAUTION
Sidewall bundles or sheets must be stored in a safe manner. The safest method of storing sidewall bundles

be secured so that they cannot fall over and cause injury. Use care when handling and moving sidewall
bundles.
Personnel operating or working around equipment must read this manual. This manual must be delivered
with equipment to its owner. Failure to read this manual and its safety instructions is a misuse of the
equipment.

Safety Decals
The safety decals on your grain equipment are safety indicators which must be carefully read and understood by all personnel involved in the installation, operation, service, and maintenance of the grain
equipment.
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal pressure
from fans or other air moving systems. Adequate ventilation and/or “makeup air” devices should be provided for all powered air handling systems. The manufacturer does not recommend the use of downward
flow systems (suction). Severe roof damage can result from any blockage of air passages. Running fans
during high humidity and cold weather conditions can cause air exhaust or intake ports to freeze.
