You may only work with a laser after you have obtained permission from your supervisor. Make sure you know the local laser safety rules.
You should at least obey the following rules:
- the sign 'Laser on' means no entry;
- for each new set-up check with your supervisor that the laser does not pose any threat to either you or others;
- make sure you know where the emergency stop is;
- do not set up the laser at eye height;
- wear laser safety goggles as much as possible, make sure these have the right filter;
- never look directly into the beam even if you are wearing laser safety goggles;
- shield off all beam reflections;
- do not wear reflective jewellery;
- make sure there are enough beam dumps to block possible reflections;
- during the prolonged use of beams wear hand and wrist protection;
- only laser workers may enter the laser lab.
