Which of the following situations poses a fire risk during laser treatment?

In the context of laser treatment, fire risks can arise from various factors involved in the procedure. The correct choice indicates that all the mentioned situations pose a risk.

Using meticulous sterile technique is essential for preventing infection, but it may not directly contribute to fire risk. However, if sterile drapes or materials are not handled properly, they can become ignited by the laser.

Employing wet dressing materials is a critical factor as damp materials can help absorb some of the laser energy, reducing heat build-up; however, if the materials are not sufficiently wet, they can still catch fire.

Applying the laser onto dry tissues significantly increases the fire hazard, as dry tissues can easily ignite under the intense energy produced by lasers. This highlights how the presence of dry, flammable surfaces is a principal fire risk.

Thus, the combination of these situations emphasizes their collective contribution to fire hazards during laser treatments. Understanding that fire risks can derive from both the treatment materials and the conditions in which the laser is applied is crucial for ensuring safety in these procedures.
