Remaining hazards with the use of the combined heat and power plant

What active dangers does the block-type thermal
power plant involve for the operators?
Regardless of the use of a combined heat and power
plant, all applicable instructions for the safe
transportation and the applicable instructions relating
to the technical installation (power, gas, heating,
ventilation) should be observed.
Hazard analysis acc. to DIN EN 12100:
What remaining active hazards are posed by
the CHP to the operators?

Radiation hazard
Hazards due to materials and substances
Hazards due to ignorance of ergonomic principles
Hazards due to slipping, stumbling, falling
Hazard combinations
Hazards in connection with the site environment
Hazards due to accidental starting and unexpected cranking
Hazards due to shutting down / emergency stop
Hazards due to changes of rotational speed
Hazards due to power failure
Hazards due to failure of the control loop
Hazards due to fracture during operation

Mechanical hazards
Mechanical hazards occur if protective covers must
be removed for finding faults or making repairs. This
includes essentially the grids covering the fan box and
the toothed belt covers of some models.
This work must only be performed by specially trained
technicians.

Electrical hazards
Electrical hazards occur if protective covers must be
removed for finding faults during start-up (works test)
or for maintenance or repair. This includes essentially
the cover of the alternator terminal box, or switches
and protective covers in the switchboard, e.g., for
adjusting the setting of the synchronizer or measuring
the alternator voltage or the mains voltage.
Wear suitable protective clothing for work on the
ignition system because a defective ignition cable can
cause electric shock.
This work must only be performed by specially trained
technicians.
