The wind cooling factor. In a calm day with temperature at 50 °F (10 °C), the weather is fresh but still warm.
With 20 mph (32 km/h) wind speed, the perceived temperature on face and hands is 32 °F (0 °C). Therefore, wear warm
clothes before starting the operations, even if temperature on the ground seems to be warm (if temperature is 32 °F /
0 °C, that perceived is 5 °F / -15 °C !).
Special attention must be taken when façade coatings are transported, as well as windows, panels and other similar
materials that can act as a "sail" and seriously compromise the machine stability, especially in presence of gusts of wind.
For the same reason, billboards and similar must not be affixed on the work platform, even if only temporary.
Moreover, the shelter and funneling effect of high or close buildings must be known and predicted, as it can increase
the wind speed in days where the speed of the wind in open zones is low.

OPERATOR'S WORKSTATION
The operator can control the machine inside the work platform (cage); if the EWP is controlled externally,
he must always keep at a safe distance, outside the dangerous zone.
2.5.
DANGEROUS ZONE
The dangerous zone corresponds to the workspace in the condition
of maximum horizontal outreach of the platform.
Keep at least 33ft / 10m away from the machine turret.

RESIDUAL RISKS
These risks cannot be fully reduced during the designing phase and with protection techniques, so they
are non-evident potential hazards.
Pay attention to the following residual risks that can occur when using the machine and that cannot be
removed.
Dangerous movements
Persons different from the operator cannot stay around the machine. Otherwise, immediately stop the
movements and oblige them to move away.
Electrical risks due to live parts and residue voltages.
Operations on the machine main electrical panel must be carried out only by skilled personnel and always
with the power supply disconnected.
Danger of mechanical nature.
Contact with the machine articulated components, such as:
- outriggers;
- column;
- arms;
can be cause of crushing and shearing of the limbs.
Danger of thermal nature
- Contact with hydraulic pumps can cause burns.
- Contact with the internal combustion or electric engines can cause burns.
- Contact with components of the hydraulic system can cause burns.
Further residual risks, according to the experience gained:
- danger due to an imperfect control of the trajectory by the operator,
- danger due to protruding parts of the machine,
- danger due to moving parts,
- danger due to instability,
- danger of crushing.
