Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of

Introduction
This International Standard is one of a series of standards produced by ISO/TC 214 as part of its program
of work regarding standardization of terminology, ratings, general principles (technical performance
requirements and risk assessment), safety requirements, test methods, maintenance, and operation for
elevating work platforms used to raise (elevate) and position personnel (and related work tools and
materials).
Mobile elevating work platforms (MEWPs) are machines/devices which provide protection from falling
when working at height.
The entities with responsibilities related to safe use of a MEWP are established by law in some countries.
This International Standard provides guidance in the identification of those responsible.
The responsibility for safe operation of a MEWP lies with employers, managers, supervisors, operators,
and others using these machines/devices. This International Standard provides requirements so that
appropriate MEWPs are selected for use and positioned, used, maintained, and examined for safe use.
The safe operation of a MEWP requires the use of competent authorized persons and trained operators
(see ISO 18878).

other reasons
3.10
qualified person
person who, by possession of a recognized degree, certificate, or professional standing, or by extensive
knowledge, training, and experience, has successfully demonstrated his/her ability to solve or resolve
problems related to the subject matter, the work, or the project
3.11

overturning
4 General requirements
4.1 Basic principles
The information in this International Standard shall be supplemented by good job management, safety
control, and the application of sound principles of safety, training, inspection, maintenance, repair,
application, and operation. All data available regarding the parameters of intended use and expected
environment shall be considered. Those with direct control over the application and operation of MEWPs
shall be responsible for the conformance with good safety practices. Decisions on the use and operation
of the MEWPs shall always be made with due consideration for the fact that the machine will be carrying
persons whose safety is dependent on those decisions as well as others in the operating vicinity.
The operation of any MEWP is su
