and Work Area
Safety Instructions
Our foremost concern is your safety and the safety of others associated with this equipment. We want to
keep you as a customer. This manual is to help you understand safe operating procedures and some
problems that may be encountered by the operator and other personnel.
As owner and/or operator, it is your responsibility to know what requirements, hazards, and precautions
exist, and to inform all personnel associated with the equipment or in the area. Safety precautions may be
required from the personnel. Avoid any alterations to the equipment. Such alterations may produce a very
dangerous situation where SERIOUS INJURY or DEATH may 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 should be
consulted before installations are made.
As a requirement of O.S.H.A., it is necessary for the employer to train the employee in the safe operating
and safety procedures for this equipment. This sign-off sheet is provided for your convenience and
personal record keeping. All unqualified persons are to stay out of the work area at all times. It is strongly
recommended that another qualified person who knows the shut down procedure be in the area in the
event of an emergency.
This product has sharp edges, which may cause serious injury. To avoid injury, handle
sharp edges with caution and always use proper protective clothing and equipment.
General Safety Statement
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 may be
encountered by the operator and other personnel.
As owner and/or operator, you are responsible to know what requirements, hazards, and precau tions exist
and inform all personnel associated with the equipment or in the area. Safety precautions may be required
from the personnel. Avoid any alterations to the equipment, which may produce a very dangerous
situation, where SERIOUS INJURY or DEATH may occur.
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 may be taken to the bin
site should also be reviewed and considered. Any electrical control equipment in contact with the bin
should be properly grounded and installed in accordance with National Electric Code provisions and other
local or national codes.
This product is intended for the use of grain storage only. Any other use is a misuse of the product.
Sidewall bundles or sheets must be stored in a safe manner. The safest method of storing sidewall
bundles is laying horizontally with the arch of the sheet upward, like a dome. Sidewall sheets stored on
edge must 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 should 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.
Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall
and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture.
If moisture is present, it must not be allowed to rema in between the sheets. Separate the sheets or panels
immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored
in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so
that they are raised above the ground and vegetation. Any stacking and spacing materials should not be
corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the
bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of
moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing
moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they
do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize
the adverse effect upon the galvanized coating.
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.
DC-969
CAUTION
GSI Group, Inc. 217-226-4421
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 reco mmend
the use of downward flow systems (suction). Severe roof damage can result from any block age of
air passages. Running fans during high humidity/cold weather conditions can cause air exhaust
or intake ports to freeze.
ATTENTION: The decal shown below should be present on the outside of the door cover of the 2 ring,
24" porthole door cover and roof manway cover. If a decal has been damaged or is missing in any of these
locations, contact the manufacturer for a free replacement decal.

1. Use CENTER FLOOR OUTLET ONLY until NO grain
remains above this outlet.
2. Side floor outlets to be used ONLY when above
condition is satisfied.
3. Lock all side floor outlets to avoid accidental
premature use.
4. See manufacturers instructions for proper use of
factory supplied sidedraw (wall) discharge systems.

Failure to heed these warnings
could result in serious injury, death,
structural damage or collapse of tank.

NOTES:
1. The foundation design is based on a minimum allowable soil bearing capacity of 3000 PSF.
Bearing capacity of the soils should be determined by geotechnical investigation and be of uniform
bearing capacity.
2. The foundation site must be free of vegetation and debris and well drained.
3. The foundation must be founded below the frost line or placed on non-expansive frost free fill.
4. All material used for backfill inside the ring wall should be clean, well graded, crushed rock or a
sand-gravel mixture. Backfill should be placed in 6" lifts, 95% compaction.
5. All reinforcement must meet the requirements of ASTM A615 grade 60 deformed bars.
6. Lap all circumferential bars 35 bar diameters and stagger all laps in plans 3'-0". Estimates for material
do not include end laps.
7. Concrete must have a minimum compressive strength of 3000 PSI at 28 days, 6%-8% air
entrainment, 4" slump.
8. Codes: UBC 97, ACI 318-95.
9. Interior top slab may be crowned 2" to provide water drainage away from foundation. Crowning the
slab will reduce the clearance under the discharge.
