The knowledge of the fire safety distance of the multiple pool fires is essential to model, manage, and mitigate the fire hazardous scenarios to safeguard the surrounding people, buildings and equipment. In this work, experiments are performed on 0.1 m gasoline double pool fires to calculate the fire safety distances using an infrared imaging technique. The distance (S/D) between the two pool is varied from 0 to 1. The irradiance from the two pools is calculated using the two-dimensional temperature field obtained by an IR camera. The calculated irradiance along the flame axial direction and on the ground is presented in a contour format. The safety distances are also represented as a function of their respective flame lengths. Two threshold heat fluxes: (I) 1.4 kW/m² and (II) 4.7 kW/m² which are required for human safety are emphasised in the contour plots for all the configurations.

了解多池火灾的消防安全距离对于建模、管理和减轻火灾危险场景以保护周围人员、建筑物和设备至关重要。在这项工作中，对 0.1 m 汽油双池火灾进行了实验，利用红外成像技术计算消防安全距离。两个池之间的距离 (S/ D ) 从 0 到 1 变化。两个池的辐照度是使用红外相机获得的二维温度场计算的。计算出的沿火焰轴向和地面的辐照度以等值线格式呈现。安全距离也表示为其各自火焰长度的函数。所有配置的等高线图中都强调了人类安全所需的两个阈值热通量：(I) 1.4 kW/m ²和(II) 4.7 kW/m ^{2 。}
