What two types of hazards are associated with laser use?

The correct answer highlights the specific dangers inherent in laser technology, categorizing them into two distinct types: beam and non-beam hazards.

Beam hazards refer to potential dangers associated directly with the laser beam itself, such as the risk of eye injury from exposure to the focused light emitted by the laser. This exposure can cause serious damage to the retina or other parts of the eye, and therefore, safety measures must focus on protecting against direct or reflective exposure to the beam.

Non-beam hazards encompass various risks associated with the use of lasers that do not directly involve the laser beam. This can include issues such as electrical hazards from the laser equipment, heat generated by the operation of the laser, and the potential for fire when using certain types of lasers in specific environments. Non-beam hazards emphasize the importance of considering the broader safety environment when working with lasers, ensuring overall safety for both the operator and any bystanders.

In contrast, other options focus on different aspects of hazards that do not capture the unique risks presented by lasers in a comprehensive manner, such as mechanical, biological, physical, chemical, electrical, or thermal risks individually, without detailing their direct implications related to laser usage.
