On this site you will find fireproof safes rated from 1/2hr to 2 hrs.
When fireproof safe have UL labels - time is indicated and this also designates
how hot the furnace temperature will get during testing. The
fireproof safes on this site have been tested at the following temperatures:
- 1/2 Hour fireproof safes- furnace heated up to 1550F
-843C
- 1 Hour fireproof safes - furnace heated up to 1700F
-927C
- 2 Hour fireproof safes - furnace heated up to 1850F
-1010C*
| This is how the fire endurance test is performed. The
contents used will be papers, computer media or both depending on the
product. The contents are distributed throughout the interior of the
product. The safe is then conditioned - which insures that at the start
of the test the interior will be between 65-75F and the humidity below
65%. |

The furnace heat then rises at a carefully monitored rate until the
specified temperature is reached. UL makes sure the furnace heat is distributed
evenly over the exposed surfaces of the product.
After the temperature and time is reached, for example 1550F for 1/2Hour,
the furnace is turned off. The product then cools in the unopened furnace. This
can take as long as 68 hours --this means that the product is continuing to be
exposed to the heat in the furnace even though it is turned off. Even though the
product is still exposed to heat it still must not exceed the humidity and
internal temperature requirements to pass the UL test.
The last step of the testing involves opening the product and examining
the interior to check for damage. Once opened, the contents are also examined to
make sure they are still in usuable condition.
We are proud at the FireSafeStore to offer only products which bear the UL
or the ETL label. Please contact us with any questions you may have about
