9.8.1 Safety instructions
Electrical current
DANGER!
Danger due to electrical current!
When working with a laser mast or the power mast in the immediate
vicinity of electrical systems, e.g. overhead cables or electric railways, a
life-threatening risk exists due to electric shock.
Therefore:
Maintain a sufficient safety distance away from electrical
systems.
If working in such systems is vitally necessary, inform the
departments or authorities responsible for these systems
prior to carrying out this work and follow their instructions.
Laser beams
CAUTION!
Risk of eye injury due to laser beams!
Laser transmitters operate with high-intensity light beams. Looking directly
into the laser beam may lead to eye injuries.
Therefore:
Do not look directly into the laser beam.
Do not point the laser beam into other persons' eyes.
Operate the laser transmitter clearly above eye level.
Improper installation
CAUTION!
Risk of injury due to improper installation!
Occasionally, laser transmitters and laser receivers have to be installed at
heights significantly above ground level. Installation using unsuitable aids
may lead to injuries.
Therefore:
Do not climb on the vehicle or power mast.
Use suitable aids (e.g. stepladders) and implement safety
precautions to install the laser transmitter on a tripod and the
laser receiver on the power mast.
