3.2 Danger of acid burning
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
calcium 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
combination with moisture (water) forms
hydrofluoric acid. The
condensate , which
accumulates in the sampling hose and in the
condensate container likewise contains acid.
Rules of conduct:
¶
When replacing the O
2
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 O
2
measuring sensors are hazardous waste
and must be disposed of separately. Your Bosch
specialist equipper can dispose of sensors in the
proper manner.
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
water and then consult a doctor.
3.3 Danger of injury, Danger of crushing
The vehicle has rotating and moving parts
that can injure fingers and arms.
If the vehicle is not prevented from rolling
away, there is a danger of people being
crushed against a workbench, for example.
There is the risk with electrically operated
fans in particular that the fan can start
running unexpectedly even when the engine
and ignition are off.
Safety measures:
¶
Take steps to prevent the vehicle from rolling away
while it is being tested. Select the park position
if the vehicle has an automatic transmission and
apply the handbrake or lock the wheels with chocks
(wedges).
¶
Deactivate the start/stop system when working on
a vehicle in order to prevent uncontrolled engine
start.
¶
Operating staff must wear work clothes without
loose bands and loops.
¶
Do not reach in any area with rotating or moving
parts.
¶
When working on or in the vicinity of electrically
driven fans, allow the engine to cool down first,
then disconnect the plug of the fan motor.
¶
Route cables at a suitable distance from rotating
parts.
¶
Secure the trolley against rolling away by setting
the brakes.
¶
Do not place heavy objects on or lean on the
sensor holder.
¶
Transport and operate the equipment only in
accordance with the operating instructions.
