CONTROLLING GENERAL HAZARDS

7.3.3
Checking tubes and hoses
Regardless of the inspections carried out at the start of the work shift, the cab
operator and ground operator
– each from their own point of observation –
must have an overall view of the drilling rig in order to warn one another of
any change in configuration. For example, a broken hose clamp might lead to
damages to the hose by crushing, cutting or stretching. Inspections must be
carried out also after accidental impacts with foreign objects during work,
although this should not happen if the work area has been adequately
prepared.
7.4 Entering and exiting the drilling rig cab
7.4.1
Proper position and movements
Do not get on or off the machine when it is moving. Do not get on
or off the machine when the hydraulic lock (E) is not activated.
When passing by the controls, there is a risk of touching them
inadvertently, starting dangerous movements. The left joystick A is
particularly exposed to this risk.
Moving it may cause the sudden rotation of the cab with serious
consequences:
•
the operator may fall from the cabin;
•
parts of the machine may hit external operators;
•
damage may be caused to the machine in proximity of obstacles or of
the rod when the bucket is in the borehole.
Keep the footboards clean from mud or earth, in order to ensure a
good grip between the shoes and the metal. Clean you shoes
before entering the cab. Mud and earth can obstruct the proper
operation of the foot controls. When getting on or off the rig, always maintain
three points of contact with it, in order to prevent dangerous swinging.
7.4.2
Cab space
The cab is designed to accommodate a single operator. Do not enter the cab
in two or more, even if only to pick up an object.
