RESIDUAL RISKS RELATED TO THE WORKED MATERIAL
There are also residual risks related to the worked material:
Risk of fire: the worked material is inflammable, so it is forbidden to use free flames close to the machine. A
correct cleaning of the machine (as stated in this manual) reduce the probability of fire on the machine;
Risk of explosion: this is related to the possibility of having explosive atmospheres (mixture of wooden
dust and air) inside the machine and in the dust extraction tubes. For all these reasons is necessary to
adopt the following rules (as in the EN 859 rule):
Check regularly that the dust extraction parameters requested by the constructor of the machine are
satisfied. These values are studied in designing the machine to avoid explosive atmospheres inside the
machine;
Connect the machine only to plants
declared in keeping with the EN12779
regulation, and in particular having primer
sensors and fire extinguisher devices (see
the figure on the right, extracted from the
above mentioned rule)
If the machine is connected to the dust
extraction plant using flexible pipes, be sure
that they are made of self-fire extinguishing,
antistatic material, suitable for grounding
any electrostatic charges due to the dust-air
mixture passing inside the pipes.
