*1. Purpose of the Safety Door*
- *Laser radiation protection*: Blocks direct and reflected laser beams that can damage eyes and skin instantly. Even diffuse reflections from metal are dangerous.
- *Physical barrier*: Stops molten metal, sparks, and cut parts from flying out.
- *Fume containment*: Keeps toxic fumes/smoke inside until extraction system removes them.
