Thermal influence from leaking liquefied petroleum gas: The radiant heat flux from 3 leakage scenarios of liquefied petroleum gas (LPG) was studied to determine safety distances when refilling LPG tanks from tank trucks. The three scenarios were a larger and a smaller leakage from a pipe and leakage from a textile reinforced rubber hose. Steady state tests with 5 minutes of burn time were performed as well as tests with 1 minute of burn time after which the emergency stop was activated. Measurements with water cooled heat flux meters and plate thermometers were used to determine heat flux levels. Measurements were designed to determine distances to heat fluxes of 12.5, 15 and 40 kW/m². Heat fluxes were measured both parallel and perpendicular to the flames at the same height as the leakage and 1 meter above the leakage.
