Working Within Dangerous Areas; High Voltage Overhead Power Line; Operating Under Ground; Working In Confined Areas - Volvo L90E Operator's Manual

Safety rules when operating

Working within dangerous areas

Working within areas where there are pipes,
power lines or cables
• It is the duty of the employer to know and mark the position of
pipes for gas, water, sewage or power lines or cables on the work
site and to inform the operator about these. Failure to do so may
have legal consequences. When required, local authorities and/or
communication and power companies should be contacted
regarding maps. drawings and advice.
• Cables and power lines must be protected against damage in a
suitable way. Electric cables should, if possible, have the power
turned off.
• Information about where the gas and water can be turned off
should be made available, so that they can be quickly turned off, if
they are ruptured.
NOTE: If digging has to be carried out very close to cables,
pipes or overhead wires, It may be necessary to dig by hand.

High voltage overhead power line

Observe great care when working in
the proximity of high
overhead power lines, as electrical
flash-over may damage the machine
and injure the operator at fairly great
distances from the power line. Bear
the following in mind:
The distance sideways between
machine and power line must be:
- at least 2 m (6.5 ft) in case of low
voltage.
- 4 m (13 ft) in case of high voltage of
at the most 40 kV (line normally
supported on fixed insulators).
- 6 m (20 ft) in case of high voltage above 40 kV (line normally
carried on suspended insulators).
The distance vertically between machine and overhead power
line must be:
- at least 2 m (6.5 ft) in case of low voltage.
- 4 m (13 ft) in case of high voltage.
The safety distances also apply to any load. The boom kick-out
(lifting height) may have to be adjusted.

Operating under ground

• Special equipment, e.g. certified engine is required within EU and
EEA countries. Talk to your dealer.

Working in confined areas

• Check that there is sufficient room for machine and load.
• Move slowly.
• Drive in the middle of a doorway which is too narrow to allow two
machines to meet.
Working near danger
areas
• Observe great care near marked
danger areas.
• Do not operate too close to the
edge of a quay, ramp etc.
