Which item is used to prevent laser ignition in an oxygen-rich environment during laser procedures?

• A. Aluminum-coated drapes
• B. Normal saline
• C. Towels
• D. Eye sponges

Answer: (A)

In laser procedures, reducing ignition risk in an oxygen-rich environment comes from using materials that won’t catch fire and can withstand laser energy. Aluminum-coated drapes are designed for this purpose—the aluminum layer is nonflammable and acts as a heat barrier that reflects or dissipates laser energy away from the fabric, greatly lowering the chance of ignition if the laser or plume contacts the drape. The other options don’t provide that protective barrier: saline doesn’t stop ignition, towels are typically combustible, and eye sponges can also ignite under laser exposure. So aluminum-coated drapes are the best choice to prevent laser ignition.
