Dry cleaning or laundering flight suits will not compromise which property and does not require renewal treatment?

• A. Flame-retardant properties are preserved but renewal treatment is required.
• B. Flame-retardant properties are lost and renewal is needed.
• C. Flame-retardant properties are preserved but renewal treatment is required.
• D. Dry cleaning or laundering will not compromise flame-retardant properties, and no renewal treatment is required.

Answer: (D)

The essential idea is that some flight suits use inherently flame-resistant fabric, meaning the flame protection is built into the fibers themselves (for example, Nomex). Because this protection is intrinsic to the material, laundering or dry cleaning does not reduce its flame-retardant properties. With inherently FR fabrics, the garment maintains its protective characteristics through cleaning, and there is no need to reapply a flame-retardant treatment after laundering. Renewal treatment is only necessary if the FR properties come from a surface-applied chemical finish that can wear off with washing. Inherent FR fabrics don’t require this re-treatment, so no renewal is needed. Just be sure to follow care instructions (avoid chlorine bleach, excessive heat, and harsh detergents) to preserve the fabric’s protective performance.
