What are the common hazards associated with laser usage?

The hazards associated with laser usage primarily include eye and skin damage due to thermal effects. Lasers produce highly concentrated light that can be harmful when it comes into contact with biological tissues. When a laser beam strikes the skin or eyes, it can generate substantial heat, leading to burns or other forms of damage. The eyes are particularly vulnerable; exposure to a laser can cause permanent retinal damage, potentially leading to vision loss. This is why precautionary measures, such as appropriate eye protection and safety protocols, are critical in environments where lasers are used.

While electrical shock, chemical burns, and mechanical injuries can occur in various industrial and laboratory settings, they are not specific hazards tied to laser use. Additionally, radioactive exposure is not relevant to laser safety concerns, as lasers do not produce ionizing radiation. Therefore, the significant concern regarding thermal effects on eye and skin is the primary focus in laser safety contexts.
