Barrier Materials

  • Should resist combustion
  • Burn or melt when subjected to oxygen accelerant
  • ALL materials burn more vigorously in the presence of oxygen

Surgical attire, such as scrubs, gowns, masks, hair and shoe covers may also ignite under the right conditions. As an example, a fiber-optic light cord disconnected from the light source and came into contact with a surgeon's scrubs, igniting them. Fortunately, the circulating nurse was able to push the surgeon to the floor and roll him to extinguish the flames.

AORN's 2006 Recommended Practice: Surgical gowns and drapes should resist combustion.

  1. Gowns and drapes selected for use should be consistent with accepted flammability standards to provide the safest environment for patients and health-care workers. Specific standards for surgical materials have not been developed. All materials used in the surgical environment will burn given the right conditions.
  2. Barrier materials are made of natural and/or synthetic fibers, and may be flammable needing only a combination of heat, fuel and oxygen to ignite. Care should be taken when gowns and drapes are exposed to light and heat sources, electrosurgical devices, lasers and other power equipment. Materials ignite and burn at various rates. Even materials said to be flame-resistant might burn or melt when subjected to intense heat or an oxygen-rich environment. Some materials not only ignite more easily than others, but also may burn more rapidly.
