Passive Fire Protection (PFP) Testing


In onshore or offshore environments, the release of flammable gases has the potential to ignite and cause significant damage, injury or loss of life.

The Health and Safety Laboratory (HSL) offers purpose-built facilities for the standardised testing of passive fire protection (PFP) materials such as those routinely used in the oil and gas industry.

PFP materials are designed to protect vessels, support structures and pipework from the high heat fluxes and erosive forces associated with jet fire impingement.


ISO 22899-1 Jet Fire Facility

HSL's Jet Fire facility has been purpose-built for testing the jet fire resistance of PFP materials and systems in accordance with BS ISO 22899-1 and BS ISO 22899-2.

To ensure that our testing assembly is fully compliant with applicable design and safety regulations, the Jet Fire facility has been independently certified by Lloyd's Register.

The facility can accommodate standard and bespoke testing of a wide range of samples including panels, tubular systems, pipe penetration seals, cable transits and cables.




Small-scale Erosive Burn Facility

HSL has developed a bespoke Small-scale Erosive Burn Facility with the aim of offering  a relatively quick, low-cost method of conducting research and development work for PFP materials and for screening systems that will undergo future ISO 22899-1 jet fire testing.

The facility is designed to subject samples of PFP to similar conditions for both heat flux and erosion that are experienced during the jet fire test. The facility can handle samples up to 370mm2 and can be run for durations of up to 3 hours per sample.




Blast Exposure Test Facility


The blast exposure test facility has been specifically designed to house 1,620mm2 samples used for jet fire resistance testing. This allows test samples to be blast tested and then jet fire tested without modification of the sample.

Bespoke blast testing requirements can also be accommodated with larger or smaller sample sizes (within limits). The facility uses ignited flammable gas mixtures to achieve the required test overpressure; this realistically recreates the heat and blast impulse duration to which the materials would be subjected during a real-world catastrophic event.


Vertical Jet Fire Facility


The Vertical Jet Fire facility at HSL is a purpose-built, full-scale ISO 22899-1 rig that allows samples of PFP to be subjected to cryogenic spills in situ before undergoing jet fire testing.

It can also be used for standard or bespoke jet fire testing where the test sample is placed in a horizontal orientation to simulate real-world conditions more realistically, e.g. a walkway.
