AI Article Synopsis
- The Mine Safety and Health Administration mandates that each person in a refuge alternative (RA) needs 1.4 m (15 ft) of floor space, but the actual space required for daily functions within an RA is not fully understood.
- Testing involved participants using various RA space configurations to perform important survival tasks, revealing that the provided floor space generally sufficed for the tasks evaluated.
- However, specific activities like changing filters, using toilets, and moving around were challenged by a minimum height of 0.6 m, indicating that future RA designs must account for height and the supplies available to ensure usability.
Article Abstract
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.
