Hi Jerald,

Thank you for your question.  

To ensure safety and compliance within a hyperbaric oxygen
therapy (HBOT) setting, it is essential that all linens, including blankets,
scrubs, gowns, pillowcases, and sheets used in a monoplace chamber, meet specific
material standards and are appropriately labeled. According to the National
Fire Protection Association (NFPA) guidelines, linens within the HBO chamber
must contain at least 50% cotton to minimize the risk of static electricity, which
could potentially lead to fire hazards in the high-oxygen environment.

Many HBOT programs opt to use 100% cotton linens to further
reduce the risk of static. To ensure that these linens meet the required safety
standards, they can be specially labeled or color-coded. Linens may be purchased
with the words “HBO” or “Hyperbaric Oxygen Therapy” directly printed on them.  They may also just have a colored stripe
indicating the cotton content. Alternatively, a specific color, such as blue or
green, may be used for linens that are made from 100% cotton, serving as a
visual identifier of the material composition.

In order to maintain safety protocols, HBOT linens are kept
separate from non-HBOT linens. This can be effectively achieved by storing
clean linens separate from non-HBOT linen and using dedicated, color-coded dirty linen bags, which are clearly marked for HBOT use. Both hospital laundry
services and HBOT staff should receive training to ensure proper linen
segregation and handling, preventing any mix-up of materials that may not meet
safety standards.

I hope this helps!
