Description
Generic hazard warning.
Positioned near the condensation discharge plug (if present), to warn of the possible
presence of hazardous substances and/or substances at a high temperature.
2.2
Mechanical characteristics risks
The following is a list of specific hazards related to the fan’s mechanical characteristics.
WARNING!
Risk of personal injury.
A person may receive injuries as a result of:
•
Being dragged between a moving part and a fixed part, for example a impeller and the
casing or some other fixed part of the fan.
•
Being dragged into the fan through the air intake, with consequent contact with the
shaft or impeller.
•
Contact with a moving part, such as the impeller.
•
Ejection from the fan exit of fragments deriving from the introduction of residual solids
or liquids extraneous to the process, or deriving from the suction environment.
•
An object drawn into the fan mouth and ejected at high speed from the fan intake or
exit.
•
Structural defects of fan components.
•
Contact with fan surfaces at dangerous temperatures, for example below -20°C or higher
than +50°C.
•
When working with hot fluids, there may be losses of jets of hot fluid from the
transmission shaft hole that may cause burns or scalds.
•
The potential harmfulness of the fluid being moved or the presence of substances that in
case of leaks may be hazardous (toxic and/or inflammable).
•
A hazard deriving from motor overspeed, which may cause the breakage of machine
parts.
•
The intake of air at abnormal temperatures higher than those recommended may cause
structural deformations, malfunctions and hazards.
2.3
Environmental risks
The fan is designed to operate in and to withstand ordinary conditions of working
environments.
The presence of the following can affect the life span of components, causing premature
deterioration, above all with respect to guards:
•
Vibrations
•
Corrosive agents (dust, gas, fumes, mist)
•
High temperatures
•
Condensation
•
Solid bodies
•
Abnormal turbulence
•
Currents of air
