What function do the folding steps serve in ISO shelters?

The folding steps in ISO shelters primarily serve to provide access to the roof. This feature is essential for maintenance, inspections, or any activities that may require personnel to access the shelter’s roof safely. By incorporating folding steps, the design ensures that users can reach the roof without undue risk, promoting operational efficiency and safety.

While there are other components of the ISO shelter structure that might serve different functions, such as securing the tarp or supporting the flooring, the specific role of the folding steps is centered around facilitating safe and convenient access to the roof area. This ability to reach the roof is critical for performing necessary tasks, such as checking for leaks, cleaning, or installing equipment.
