6 NETBEAT USER MANUAL
INTRODUCTION
Thunderstorms
If the area is known to be prone to thunderstorms, NetRTUs installed in the fields, may attract lightning
discharge, as they are the highest object in the vicinity.
In such case it is recommended to install a lightning rod in the NetRTUs vicinity.
A lightning rod is a metal rod installed on a pole and grounded.
The lightning rod should be the highest object in the vicinity in order to properly attract the lightning
discharge and direct it safely into the ground.
Working at height
WARNING
Mounting the base unit and routers and erecting poles might require working at height:
To prevent fatalities or major injuries, all safety measures regarding work at height must be observed.
Without limiting the foregoing:
Avoid work at height whenever possible.
As much work as possible should be done from the ground (whenever possible: mount the unit
on the pole, wire it and then erect the fully equipped pole into position).
If work at height cannot be avoided:
All work at height must be properly planned, supervised and carried out by competent, trained
and experienced personnel, authorized by the local safety authority.
Make sure equipment used for work at height is certified by the local standards authority, well
maintained and inspected regularly.
Avoid standing on fragile surfaces such as shingle or asbestos cement roofs.
For the entire duration of work at height a person should be present on the ground, constantly
keeping eye-contact with the workers at height, ready to assist them when needed.
When working at height make sure that nobody is standing under you.
Make sure the surface, scaffold or ladder used are stable and strong enough to support the
worker’s weight and that of the equipment.
Always wear a harness and make sure it is correctly anchored to a stable element.
Always use tools designed for work at height and make sure that they are secured in a basket
preventing them from falling.
