Hazards due to heat
During operation, the combustion engine in the block-
type thermal power plant and the downstream heat
generation components and the exhaust line become
very hot; the temperature can reach several hundred
degrees centigrade at exposed points. All pipelines
and components are insulated as far as possible.
However, some points are accessible freely for
service and installation. These can become hot in
operation and are not protected against accidental
touching, e.g., the measuring fitting for exhaust gas
back pressure.
If a fault develops, the safety pressure limiter can trip
and discharge hot cooling water. This can involve the
risk of scalding.
Hazard due to noise
Use suitable hearing protection when working on the
cogeneration module during operation with open
noise cover, e.g., during fault finding or repairs.
Hazard due to radiation
Electromagnetic fields emanating from generators in
the block-type thermal power station can temporarily
disturb any heart pacemaker in its immediate vicinity.
The signs of a potential disturbance might be
dizziness, palpitations or an irregular pulse. The heart
pacemaker functions normally as soon as the person
wearing it moves away from the generator.
Hazards due to materials and substances
Like a car, the block-type thermal power plant is
started by batteries. The batteries are filled with
battery acid. Battery acid has caustic effect. Avoid
skin contact and observe the applicable safety
instructions.
The same is true of cooling water containing glycol
and the lubrication oil of the engine. Wash the parts of
your body in contact with these substances with
copious amounts of water and apply body care agent.
Waste gas might escape uncontrollably if there are
leaks in the waste gas system (causing the hazard of
carbon monoxide poisoning). However, it is normally
conducted outside by the extract ventilator cowl
through an extract air duct. Therefore it is important to
watch out for leaks when carrying out service work on
the open machine and to ensure that the sound-
absorbing hood is closed during operation.

Hazards due to breakage in operation
Particular care is required when the CGP module is
lifted by crane; observe the crane hook and the
transport lugs.
Breakage can cause leaks in overheated
components. Hot engine oil, heating or cooling water
can gush out. For example, hoses can burst or test
fittings break away.
It cannot be excluded that - like in cars - the engine
can break and fragments be ejected in very rare
cases.
If parts of the exhaust system break or corrode, toxic
carbon monoxide can escape. In this case, switch off
(shut down) the block-type thermal power plant
immediately and start the ventilation.
Hazards due to operation in potentially explosive
atmosphere
It is permitted to set up, operate, maintain and run the
cogeneration module in a potentially explosive
atmosphere (ATEX zone) only if one of the two
following fundamental conditions exists:
1.
2.
The personal protection equipment comprises:
Hearing protection (work on the running block-type
thermal power plant with open noise cover)
Protective gloves and goggles when handling battery
acid, glycol or engine lubricating oil
EU directive relating to appliances burning gaseous fuels
EU pressure vessel directive
EU machine directive
EU low voltage directive
EU electromagnetic compatibility directive
Safety of machinery – Electrical equipment of machines
Part 1: General requirements
Safety of machinery – Fundamental terminology, general design principles
Constant mechanical ventilation (exhaust) of the
technical room prevents a potentially explosive
mixture.
The gas supply line is fitted with a gas warning
system and a sufficient number of sensors at
strategic points.
In this case, when the gas concentration is at the
lower alarm limit, the mechanical room
ventilation (exhaust) is switched on, the
cogeneration module can be switched off and
the gas main solenoid receives a closing signal.
