Which material is acceptable to use with flammable chemical cleaning agents on aircraft?

Using cotton fiber wiping cloths with flammable chemical cleaning agents on aircraft is appropriate because cotton is a natural fiber that tends to be less prone to static electricity buildup compared to synthetic materials. This characteristic is particularly important when working with flammable substances, as static electricity can ignite vapors or residues present in the materials being cleaned. Cotton also absorbs liquids well, allowing it to effectively handle spills or residues from cleaning agents.

In contrast, synthetic wiping cloths can generate static electricity, which poses a risk of igniting flammable vapors. Paper towels, while absorbent, may not be as robust for heavy-duty applications and can disintegrate when wet with certain chemicals. Microfiber cloths, although excellent for dusting and general cleaning, can also produce static charges and may not be suitable for use with flammable agents due to their synthetic composition. Thus, cotton fiber wiping cloths provide a safer alternative for cleaning tasks involving flammable chemical agents on aircraft.
