1. Can I pressurize
Snyder IBCs?
No, most plastic IBCs are not designed to be pressure vessels. However,
each IBC is production tested to 3 PSIG, and design qualification tests,
required for U.N. marking of an IBC, vary from 14.7 PSIG to 62 PSIG. for a
period of 10 minutes, depending on design type and applications. In some
cases, users or shippers of IBCs may want to put a N2 blanket on the
product or apply some pressure to help facilitate certain off-loading
application requirements. Minimal intermittent pressure exposure of
between .5 PSIG - 5 PSIG, for all IBC design types marked with a test
pressure = 14.7 PSIG is possible to address these requirements.

2. Do Snyder IBCs have to be vented
before unloading?
All Snyder IBCs come equipped with an automatic vacuum vent, which begins
relieving internal tank pressure at .25 PSIG, so no manual operation is
necessary by IBC users.

3. How long will a Snyder IBC last?
Useful life is dependent on many variables, including chemical attack, IBC
design type, UV exposure, and handling wear and tear. Snyder Industries
has tanks that have been in the field for over twenty years. While the
latest generation of thick walled IBCs have been on the market for only 10
years and many of those original units are still in service, it is
difficult to make a judgment on expected useful life. For additional
information regarding tank life please review the Snyder Tank and IBC
Environmental Stress Inspection Guide.

4. What is the difference between Snyder's rotationally
molded IBCs and the "caged", blow molded plastic IBC design
type?
Snyder IBCs are typically acquired as an asset for long-term use in
reusable/returnable shipping and handling applications. The lighter duty
caged plastic IBCs are primarily sold for one-way or limited reuse
shipping applications. Reason being, Snyder's IBCs are four times thicker,
corrosion proof, and substantially more impact resistant, which results in
a much longer lasting and more durable IBC
construction.

5. Can I ship filled IBC's stacked.
How high can I stack them?
If IBC's are UN labeled, they can be stacked two high when full, as long
as the rated gross capacity is not exceeded.
top
6. Can an IBC be FDA
approved?
"Designs" are not approved by the FDA, they only approve the
MATERIAL used to construct the tank. Snyder can build IBC's using FDA
compliant materials.

7. Can I stack filled IBC's for storage?
You can stack a Snyder IBC 3 high for storage, as long as you don't exceed
the rated gross capacity of the container or the stacking test load shown
in the U.N. marking.

8. How long has Snyder been manufacturing
plastic containers?
Snyder has been manufacturing plastic containers for over 45 years in
Lincoln, Nebraska. We have expanded over the years to include 4 additional
plants with similar manufacturing capabilities. Snyder is the most
experienced plastic IBC manufacturer in the U.S. We have a full staff of
Engineers and testing personnel.

9. How often does the DOT/UN Marking have to
be updated?
Snyder IBCs must be retested every 2 ½ years for either UN31H1 or UN31H2
marked units.

10. Where can I find information regarding
Department of Transportation Hazardous material regulations?
The following link will take you to the Department of Transportation
Research and Special Programs Hazardous Materials Website. This is an
invaluable resource for anyone involved with the shipment of or the
offering for shipment of Hazardous Materials in U.N. Marked IBC's. http://hazmat.dot.gov
