What temperature and relative humidity is ideal for working with parachutes?

The ideal temperature and relative humidity for working with parachutes is 75 degrees and 60 percent. This combination is optimal for maintaining the integrity and performance of parachute materials, as well as ensuring the comfort and effectiveness of personnel handling them.

At this temperature, the environment is comfortable enough for aircrew and ground personnel to work efficiently. The 60 percent relative humidity strikes a balance; it is humid enough to prevent static buildup, which could lead to issues with the parachute fabric, but not so humid that it compromises the materials. Excessive humidity can weaken fabric and potentially lead to mold or mildew growth, while very low humidity can increase the risk of static electricity and fabric brittleness.

Temperature and humidity levels outside this ideal range could create challenges. For example, temperatures too high can lead to heat stress for personnel, while too much humidity can lead to the aforementioned issues with fabric. This makes 75 degrees and 60 percent the most suitable conditions for effectively managing parachutes.
