About Lesson
Despite their versatility, lasers pose several risks that require appropriate safety measures:
-
Eye Hazards:
- Exposure to powerful laser beams can lead to permanent damage or blindness. This occurs when the retina absorbs excessive energy, causing thermal or photochemical injury.
- Protective Measures: Laser safety goggles are essential for protecting against specific wavelengths.
-
Skin Hazards:
- High-intensity laser beams can cause severe burns to the skin if prolonged exposure occurs.
- Precaution: Wear protective clothing and gloves to minimize risk.
-
Fire Hazards:
- High-power lasers may ignite combustible materials such as paper, plastics, or flammable liquids.
- Safety Control: Implement fire-resistant barriers and have fire extinguishers nearby.
-
Electrical Hazards:
- Lasers operate using high-voltage sources that could lead to electrical shocks or fires.
- Precautions: Proper grounding and safety interlocks are critical to prevent accidents.
