The Mine Safety and Health Administration requires that 1.4 m (15 ft) of floor space is to be provided for each person inside a refuge alternative (RA). However, the amount of floor space needed for a person to reside inside an RA and perform basic tasks is unknown. During testing, participants entered into an RA or a simulated RA of various space/volume configurations and performed several simulated tasks that are representative of the survivability tasks performed within an RA. The results indicate that the floor space requirements were generally adequate for the tasks studied. Certain tasks such as changing scrubber cartridges, using toilets, and moving about the RA were impacted by the minimum height tested (0.6 m). As such, RAs of this height will require critical design consideration as a whole and the supplies provided for use inside of the RA to ensure the ability to use an RA.
美国矿山安全与健康管理局要求，在备用避难所（RA）内，每人需有1.4米（15英尺）的占地面积。然而，一个人在备用避难所内居住并执行基本任务所需的占地面积尚不清楚。在测试过程中，参与者进入不同空间/体积配置的备用避难所或模拟备用避难所，并执行了一些模拟任务，这些任务代表了在备用避难所内执行的生存任务。结果表明，对于所研究的任务，占地面积要求总体上是足够的。某些任务，如更换洗涤器滤芯、使用厕所和在备用避难所内移动，受到测试的最小高度（0.6米）的影响。因此，这种高度的备用避难所作为一个整体需要进行关键的设计考量，以及为在备用避难所内使用而提供的物资，以确保能够使用备用避难所。
