2.2 General safety instructions
2.3 Safety devices
In the process of designing and building the fan, the manufacturer adopted the necessary technical solutions to
ensure compliance with fundamental safety requirements: the object of the risk reduction process was to ensure
that the operator can use the fan in safety. The machine is provided with protection devices of fixed type and is
fitted with an actuator for the emergency stop function.
Fixed guards
The fixed guards are solidly fixed to the structure of the machine and cannot easily be eluded: the guards are fixed
with systems which require the use of tools for dismantling.
Operators must be trained to deal with the occurrence of possible faults,
malfunctions or dangerous conditions to themselves or others, and in such an
event must:
•
stop the fan immediately by operating the emergency stop device (mushroom-
shaped pushbutton/main switch mounted on the electrical panel);
•
not carry out operations which are beyond their duties and/or technical
knowledge.
WArNINg
•
Safety devices must not be removed or rendered ineffective;
•
the fan must not be started with guards removed;
•
any adjustment or maintenance operation must be performed with the
electrical isolating device activated and locked in position with a padlock;
•
any operation is prohibited which may cause arcing or sparks or other
situations which could start a fire;
•
in the event of alarm signals resulting in the intervention of safety devices, the
operator must ask for immediate action by qualified technicians responsible
for maintenance;
•
user must ensure that the environmental and electricity supply conditions
in which the fan operates are always within the limits specified in this user
manual;
•
do not for any reason modify parts of the fan in order to fit additional devices.
WArNINg
Do not start the fan with fixed guards removed: the guards can only be removed
with special tools, by specialized and trained personnel and with the system
stationary (emergency system activated and electricity and hydraulic fluid
isolated). At the end of maintenance operations, the guards which were removed
must be replaced correctly.
