The following explains the used terms and abbreviations:
TERM
DEFINITION
Lifting accessories
Components or equipment not connected to the machines that allow, located
between the machine and the load or on the load itself, the grasp of the load. The
harnesses and their components are also considered lifting accessories.
ATEX
It derives from the words ATmosphères and EXplosibles and it is the conventional
name that groups two directives of the European Union (EU):
•2014/34/EU for the regulation of the equipment used in explosion risk areas;
•99/92/CE for the safety and health of the workers in explosive atmospheres
or in explosion risk environments.
Failure
A general failure that prevents the normal operation of a machine, a plant, etc.
Chains, ropes or straps
Elements designed and built for lifting purposes as an integral part of lifting machines
or lifting accessories.
Damage
Any adverse consequences resulting from the occurrence of a dangerous event.

EC-compliant use and warning instructions
Page 16
CHAPTER 2 –PRELIMINARY INFORMATION
TERM
DEFINITION
D.P.I.
The term Individual Protection Device (acronym DPI) refers to products that have the
function of safeguarding the worker (operator, maintainer, technician, etc.) that you
wear or take them with you, from health and safety risks.
breakdown
Element totally deprived of normal ability to execute a required function.
Support
Equipped or intended to be equipped with an activation system, composed of parts
or components, at least one of which moves, connected to each other solidly for a
well-established application.
Malfunction
Faulty or inappropriate operation of a machine or one of its elements performing a
particular function.
Protection measure
Expected measure to achieve risk reduction, implemented:
•By the designer (inherently safe design, additional protections and
protection measures, information for use) and/or
•By the user (organization: safe working procedures, surveillance, work
permits; provision and use of additional means of protection; use of
personal protective equipment; training).
Danger
Potential source of damage that, if not avoided, implicates a risk to the safety and
health of the people exposed.
Exposed person
Any person who is entirely or in part in a dangerous area.
Prevention
The set of necessary provisions or measures, also according to the particularity of
the work, experience and technique, to avoid risks or reduce the chances of
happening.
Protection
Defense against what could harm. An element that is between those who can suffer
the damage and what can cause it for hazards that cannot be reasonably eliminated
or for risks that cannot be sufficiently reduced during design. We distinguish:
•active protection that the operators themselves must activate (emergency
stops for example) and/or wear (DPI);
•passive protection that intervenes even without human command.
Barrier
Physical barrier, designed as part of the machine, to provide protection.
Fixed Barrier
Protection held in place (i.e. closed) or permanently (welded) or by means of
fastening systems (screws, bolts, etc.) that make it impossible to remove/open
without the help of tools (keys, screwdrivers or hex key). Easy-to-remove fasteners
are not allowed (e.g. plastic knob).
Mobile Barrier
Barrier mechanically connected to the machine structure (e.g. with hinges or guides)
that can be opened without the use of tools.
Risk
Combination of the probabilities of damage and the severity of that damage.
Residual risk
Risk that remains after taking protection and prevention measures.

Expected use
Use of a machine in accordance with the information provided in the instructions for
use.
Reasonably predictable
