Here is a video putting a Justrite Flammable Cabinet through a 90 minute fire test to see how it performs.

The Justrite flammable cabinet did an excellent job. The critical function it performed was protecting the contents stored in the cabinet. The cabinet allowed at least 90 minutes for:
  1. staff members to safely evacuate the building and
  2. emergency services to extinguish the fire before the contents of the cabinet added more damage to the property.
