90 minutes – development and timeline of a fire


In the event of a fire, the 90 minutes of tested fire protection is the decisive factor in protecting human life and minimising damage to property.

DÜPERTHAL safety storage cabinets with fire resistance rating Type 90 allow sufficient time for workers to leave the room in the event of a fire and allow the fire brigade sufficient time to get into the laboratory. Just before a smaller extinguishable fire from stored flammable substances causes an uncontrollable fire. The cabinet is tested under fire conditions as standard. Each cabinet model is type-tested in a fire chamber in accordance with DIN EN 14470-1. The test parameters and test temperatures in the fire chamber and directly in the cabinet are specified in the standard, and further details are provided on the following pages.
