Jet Fire Testing

Jet fire testing performed by BakerRisk allows for a jet fire to impinge on a building structure that is sufficiently large to be representative of a potential jet fire at a petrochemical facility. BakerRisk elected to develop a large scale jet fire test program to provide a better understanding of the hazards associated with jet fires and refine the computer models used for facility safety assessments.

A large quantity of experimental work on jet fires has involved testing passive fire protection materials using the guidelines provided in ISO 22899-1:2007. These tests provide valuable information on the effectiveness of the fire protection materials and structural components but the experiments do not provide information on the impact of jet fires on entire structures such as office buildings, trailers, shipping containers, and blast resistant modular buildings that are common at petrochemical facilities.

The test rig used to accomplish the jet fire tests is essentially a large propane tank, vaporizer, and release point. The fuel-air mixture is ignited. The resulting jet fire has the capability to engulf a portion or all of the building structure. This test setup is illustrated below.

Typical temperature time histories are shown below for a range of standoff distances from the surface impinged by the jet fire. Photographs of the jet fire test rig just prior to and after ignition are shown below.

The jet fire test rig provides the capacity to produce large scale jet fires. The jet fire test rig is designed to support testing of a wide range of structures or structural components, including:
