�.1.2 Highvoltagesinhybridvehiclesandelectricve-
hiclesaswellastheirhigh-voltagecomponents
If high-voltage components or high-voltage
wires are inexpertly handled, there is a risk of
fatal injury from high voltages and the possib-
le transmission of current through the body.
¶
Deenergization is only to be performed by
a qualified electrician, a qualified electri-
cian for specific tasks (hybrid) or a power
systems engineer.
¶
Work on vehicles with high-voltage compo-
nents is only ever to be performed in a safe,
deenergized condition by persons with the
minimum qualification "Trained to perform
electrical work".
¶
Even after deactivating the high-voltage
vehicle electrical system, the high-voltage
battery may still be live.
¶
Operating condition cannot be established
from any running noise, as the electric ma-
chine is silent when stationary.
¶
In gear positions "P" and "N" the engine or
electric motor may start spontaneously depen-
ding on the charge of the high-voltage battery.
Safety measures:
¶
Never open or damage high-voltage batteries.
¶
On accident vehicles, never touch high-voltage com-
ponents or exposed high-voltage wires before deacti-
vating the high-voltage vehicle electrical system.
¶
Avoid contact with any high-voltage components
and high-voltage wires (orange sheathing) when in
operation.
¶
Secure against unauthorized renewed start-up
(e.g. by means of a padlock).
¶
Always wait at least 10 seconds after deactivating
the high-voltage system.
¶
Visually inspect the high-voltage components and
high-voltage wires for damage. The power systems
engineer responsible should always be immediate-
ly notified of any irregularities, doubts or defects
found.
$
High-voltage components must never exhibit signs
of external damage.
$
The insulation of the high-voltage wiring must be
intact and undamaged.
$
Watch out for any abnormal deformation of the
high-voltage wiring.

�.2 Dangerofacidburning
When exhaust gas measurements are taken,
the sampling hoses which are used release a
highly caustic gas (hydrogen fluoride) that can
cause acid burning in the respiratory system
when heated to temperatures in excess of
250 °C (482 °F) or in the event of fire.
Rules of conduct:
¶
Consult a doctor immediately after inhaling!
¶
Always wear gloves made of neoprene or PVC when
removing residues left after a fire.
¶
Neutralize any residues left after a fire with a cal-
cium hydroxide solution. This produces non-toxic
calcium fluoride, which can be washed away.
Acids and alkalis can cause severe burning on
unprotected skin. Hydrogen fluoride in combi-
nation with moisture (water) forms hydroflu-
oric acid. The condensate, which accumulates
in the sampling hose and in the condensate
container likewise contains acid.
Rules of conduct:
¶
When replacing the O2 measuring sensor, bear in
mind that it contains alkali.
¶
When replacing the NO measuring sensor, bear in
mind that it contains acid.
¶
Rinse any affected parts of the skin immediately in
water, then consult a doctor!
¶
NO and O2 measuring sensors are hazardous waste
and must be disposed of separately. Your Bosch spe-
cialist equipper can dispose of sensors in the proper
manner.
If liquid crystal escapes from a damaged liquid
crystal display, it is imperative to avoid direct
skin contact, inhalation and swallowing.
Rules of conduct:
¶
If you have inhaled or swallowed liquid crystal, con-
sult a doctor immediately!
¶
Wash the skin and clothing thoroughly with soap and
water if it has come into contact with liquid crystal.
If fluid (electrolyte) escapes from batteries
and rechargeable batteries, avoid getting it on
your skin or in your eyes.
Rules of conduct:
¶
If contact with skin or eyes happens nevertheless,
wash the affected parts immediately with clean wa-
ter and then consult a doctor.
