Personnel training
All operators engaged in the use of the fan must
have received adequate information from the
employer relating to:
• risks to health and safety at work connected with the

their capabilities in the interests of safeguarding their
health and safety;
• to provide adequate means of protection;
• to require compliance by individual operators with the
company rules and provisions regarding safety and the
use of the collective and individual protective measures
at their disposal;
• to ensure that normal and special maintenance
operations, or in any event operations necessary for
machine safety, are regularly carried out.

as well as that of other people in the workplace who may
be affected by their actions or omissions, in accordance
with their personal skills, and the instructions and means
provided to them by the employer.

3.3 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.
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.
