CASE STUDY 1: FIRE AT WHARFDALE HOSPITAL
This fire occurred in an extension to the hospital under construction. An arsonist ignited a solvent based adhesive poured over a large pile of combustible building materials that was stored in the ground floor of the facility. The ground floor was essentially open with the external cladding starting at the first floor level.
We commissioned Tenos to perform an independent investigation into the fire. This involved a visit to site and discussions with West Yorkshire Fire & Rescue. A detailed report is available.
The Tenos report concludes, “In spite of significant heat generated by the fire (sufficient to damage the intumescent coating and distort the steel beams); the orientation of the cladding panels directly above the fire; and the fact that the fire stopping was not in place; the cores of the panels did not ignite; did not promote fire spread within the core or to the eaves and did not significantly contribute to the products of combustion.”
CASE STUDY 2: FIRE AT CLIFTON COMPREHENSIVE SCHOOL.
A serious fire took place in the roof void of a new school building in Rotherham. In this case Kingspan KS1000 LP (Lo-Pitch) LPCB approved roof panels were exposed to an intense fire in an aerial walkway. The fire was investigated by Tenos and South Yorkshire Fire Service and again it was clear that the panels played no role in fire spread and actually played a key role in preventing fire propagation over a compartment wall.
The fire took place just 6 weeks before the facility was due to open, the building contained many thousands of pounds of brand new computers and other equipment. The fact that there was no smoke damage to the equipment and the building opened on schedule demonstrated the excellent fire performance of the cladding system.
