DESCRIPTION
Diesel Engine exhaust spark arrestors are a key safety feature for both
hazardous area and lower risk diesel engine applications where a stray
spark may cause ignition of combustible material. Virtually all
legislation regarding the operation of a diesel engine in a hazardous
area includes a mandatory requirement to fit a tested and approved
exhaust spark arrestor.
MAINTENANCE
Daily: Examine the spark arrestor for any sign of gas leakage, cracks
or significant areas of damage, i.e. dents of more than a few millimetres
in depth.
Three Monthly: Remove spark arrestor. Tap with a soft mallet to
loosen any internal deposits and shake out. Also by shaking check for
any loose internal baffles.
Six Monthly (or 1500 hours operation, whichever is sooner):
Examine the exhaust discharge in darkness whilst repeatedly loading
and accelerating the engine. If any sparks are observed, the spark
arrestor is not suitable for further use.
OPTION - SPARK ARRESTOR
NOTE: Ensure adequate ventilation if this check is carried out in an
enclosed area.
NOTE: The engine must not be put back into service until any
problems identified by the above checks are rectified.
