General laser safety
The following general laser safety guidelines should be followed at all times
.
Never look into the direct path of a laser beam or its reflections.

Never look into the expected path of a laser beam without ensuring by posi-
tive means that the laser cannot be excited.
.
While carrying out any operations in which the laser can be exposed, wear
protective goggles, ensuring that they are suitable for the power output and
wavelength of the laser in use and avoid, even when wearing such goggles,
direct viewing along the paths of the laser beam.

Only authorised personnel should be allowed to enter the area where serv-
icing of the instrument is taking place.
.
Avoid traversing the laser beam with any reflective object.
