3.4 Danger of burning
When working on a hot engine, there is a risk
of injury from burning if such components
as the exhaust gas manifold, the turbo-
charger, the Lambda sensor, etc. are touched
or if parts of the body come too close to
them. These components may be heated to
temperatures of several hundred degrees
Celsius. Depending on the duration of the
exhaust gas measurements, the sampling
probe of the exhaust gas measuring
instrument may also become extremely hot.
Safety measures:
¶
Always wear protective clothing, e.g. gloves.
¶
Allow the engine to cool down first. This also
applies to auxiliary heating systems.
¶
Keep connecting cables well away from all hot parts.
¶
Do not leave the engine running any longer than
necessary for the test or setting.
3.5 Danger of fire, Danger of explosion
There is a risk of fire and explosion
from fuels and fuel vapors when work is
performed on the fuel system or on the
mixture control system.
Safety measures:
¶
Switch off the ignition.
¶
Allow the engine to cool down first.
¶
Avoid naked flames and potential sources of sparks.
¶
Do not smoke.
¶
Collect any leaked fuel.
¶
Always ensure effective ventilation and suction when
working in closed areas.
3.6 Danger of asphyxiation
Car exhaust fumes contain carbon monoxide
(CO) - a colorless, odorless gas. If inhaled,
carbon monoxide causes an oxygen
deficiency in the body. Extreme caution is
therefore essential when working in a pit, as
some of the components of the exhaust gas
are heavier than air and settle at the bottom
of the pit. Caution is also necessary when
working on LPG-driven vehicles.
Safety measures:
¶
Always ensure effective ventilation and suction
(especially when working in a pit).
¶
Always switch on and connect the suction plant in
a closed area.
3.7 Danger of tripping
When conducting tests or making
adjustments, the sensor and connection
cables increase the risk of tripping.
Safety measures:
¶
Route the connecting cables such that any risk of
tripping up is prevented.
3.8 Noise
Noise levels in excess of 70 dB(A) can occur
when measurements are carried out on a
vehicle, especially at high engine speeds.
Damage to hearing may result if human
beings are exposed to noise at such levels
over an extended period of time.
Safety measures:
¶
Noise protection facilities must be provided by the
owner at all workplaces in the vicinity of the testing
area.
¶
Suitable personal noise protection facilities must
be used by the operator.
