Options for operating in fire hazard areas
Diesel motors represent a potential source of ignition in environments with concentrations of gas,
vapour or dust, and may cause major fires with disastrous consequences for people, the environ‐
ment and production.
For the operation in fire hazard areas, the machine is equipped with the following accessories:
■ Spark arrestor
4.9.4.1 Option la
Spark arrestor
Sparks in exhaust fumes represent a considerable risk in environments with flammable materials.
Flying sparks combined with flammable materials may cause fires and explosions.
A spark arrestor on the exhaust silencer is required when operating a diesel engine in a fire hazard
area and in forestry and agricultural applications. In such applications, a spark may ignite flamma‐
ble materials.
A spark arrestor mounted on the machine roof prevents the escape of burning combustion residue
from the exhaust silencer.
