What is one potential danger of class 4 laser systems?

Class 4 laser systems are among the most powerful lasers available and present significant hazards. One of the primary dangers associated with these lasers is their potential to cause fires. This can occur when the laser beam interacts with materials that can ignite, especially flammable substances or surfaces. The energy emitted by a Class 4 laser can produce enough heat to initiate a fire, making it crucial for facilities using such lasers to implement stringent safety protocols, including proper ventilation and the management of materials in the surrounding environment.

The other considerations do not effectively characterize the hazards of Class 4 lasers. For instance, they can cause severe eye damage rather than only minor irritation, as hinted at in the first option. Additionally, Class 4 lasers can cause skin damage and are indeed capable of affecting individuals at a distance, especially if the beam is not properly controlled. Therefore, understanding the specific risks associated with Class 4 lasers is essential for ensuring safety in environments where they are utilized.
