Wire rod ties, which hold bundles of bars or pipes, must not be used to hoist those same bundles.
Once the load is slinged, check its balancing by slowly hoisting the load by a few centimeters. The suspended load must never be
guided by hand, but only with ropes or hooks. The non-intervention of protections and of safety equipment or wrong maneuvers or the
incorrect use of PPEs may result in the following hazards
CRUSHING
SPECIFIC SAFETY REQUIREMENTS
The appropriate specific safety requirements for load hoisting machinery are listed hereunder:
• Maximum admissible capacity must be displayed on all hoisting equipment (not including hand operated ones) and hooks.
• Hooks must be fitted with safety catches or be shaped so as to prevent ropes, chains or other slinging apparatus from
coming unhooked.
• Ropes and chains of hoisting machines must be checked every quarter by qualified
staff, and be registered on the appropriate page of the matriculation-book.
• Load hoisting and hoisting-moving maneuvers must be designed so as to prevent
suspended loads from traveling above workers and places where the load fall might
be dangerous. If such transit is unavoidable, load hoisting and/or handling
maneuvers must be timely announced by appropriate and dedicated signals in
order to allow, where possible, people to move away from the area where they
might be exposed to danger if a load fell down.
• Hoisting and handling machines must be fitted with braking devices which can
guarantee a prompt stopping and a stand still position of load and machine and,
when required for safety purposes, guarantee a smooth stopping.
• When a black-out might endanger people, hoisting machines must be fitted with
devices which will cause both the load and the machine to stop automatically.
However, the stopping must always be smooth in order to avoid excessive stress as
well as to prevent the stability of the load from being compromised by dangerous
swinging.
Further and/or different safety requirements may be prescribed for a machine and the above information are therefore to be
considered neither exhaustive nor mandatory.
• Motor operated elevators must be built so as to work with the motor engaged even while lowering
• While using hoisting and handling machines, the necessary measures in order to guarantee the stability of the machine and
of its load, depending on the type of machine, on its speed, on accelerations at starting and stopping and on the
characteristics of the route.
CHIEF BEHAVIOR RULES FOR WORKERS AND PROCEDURES
Each worker shall pay the greatest attention during operations, following the instructions supplied by the employer, by managers and
by the persons in charge as well ass the information contained in the user’s manual of the machine.
CHIEF ACCIDENTS
The notes hereunder do not ensue from statistical data, which at the moment are not available, but from experiences collected in
factories and among people working in this field.
