3409 Research report: Fire resistance testing of sealant materials and system components for secondary containment construction/expansion joints

Overview:

The tests reported in this research report have been independently conducted to compare the fire resistance performance of different sealants and systems components that are typically in use forming seals in existing secondary containment construction/expansion joints for bulk above-ground storage tanks.

This publication investigates the results from these tests that were carried out to examine the fire resistance duration and liquid retention capabilities/integrity of the sealant systems used under real-world fire conditions, as opposed to standardised furnace testing.

This research report provides conclusions and recommendations regarding sealant and joint system behaviour under fire conditions, as well as fire resistance and liquid retention specification aspects and implications for emergency response. These are included in the related Guidance on selection, installation and management of fire resistant sealant materials and system components for secondary containment construction/expansion joints, alongside other issues to ensure joint integrity.
