Introduction
This European Standard is one of several ergonomics standards for the safety of machinery. EN 614-1
"Safety of machinery – Ergonomic design principles – Part 1: Terminology and general principles" describes
the principles designers should adopt in order to take account of ergonomic factors.
This European Standard describes how these principles should be applied to the design of openings which
will allow whole body access. This standard has been prepared to be a harmonized standard in the sense of
the Machinery Directive and associated EFTA regulations.
1 Scope
This European Standard specifies the dimensions of openings for whole body access as applied to machinery
as defined in EN 292-1. It provides the dimensions to which the values given in EN 547-3 are applicable.
Values for additional space requirements are given in annex A. This European Standard has been prepared
primarily for non-mobile machinery, there may be additional specific requirements for mobile machinery.
th th
Dimensions for passages are based on the values for either the 95 or the 99 percentile of the expected user
th
population. Values for the 99 percentile apply to emergency egress routes.
The anthropometric data given in EN 547-3 originate from static measurements of nude persons and do not
take into account body movements, clothing, equipment, machinery operating conditions or environmental
conditions.
This European Standard shows how to combine the anthropometric data with suitable allowances to take
these factors into account.
Situations where people are to be prevented from reaching a hazard are dealt with in EN 294.
2 Normative references
This European standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to
this European Standard only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies.
EN 292-1, Safety of Machinery - Basic concepts, general principles for design - Part 1: Basic terminology,
methodology.
EN 294, Safety of Machinery - Safety distances to prevent danger zones being reached by the upper limbs.
EN 547-3, Safety of Machinery – Human body measurements – Part 3: Anthropometric data.
EN 614-1, Safety of Machinery - Ergonomic design principles – Part 1: Terminology and general principles.
3 General requirements
This European Standard specifies the relevant dimensions of openings with respect to different body
positions.
In arriving at values for these dimensions, in addition to the basic anthropometric data it is necessary to add
allowances to permit unhindered and safe entry and working, taking into account aspects specific to the
operator and to the operating conditions.
In this respect the following criteria are of particular significance:
a) Ease of passage of a person is influenced by:
 The type of clothing, e.g. light or heavy clothing;
 Whether tools are being carried, e.g. for maintenance or repair purposes;
 Whether additional equipment such as personal protective equipment (including protective clothing),
or portable lighting, is being carried or worn;
 The demands of the task, e.g. posture, nature and speed of movement, lines of sight, application of
force;
 Frequency and duration of task;
 Length of passage, e.g. through a relatively thin wall (wall of a vessel) where there is space for
movement at the exit or through a channel type passage;
 amount of space available to allow for the dynamic nature of movement to escape from danger;
 the position and size of supports for the body, e.g. foot support, hand holds;
b) environmental conditions (e.g. darkness, heat, noise, moisture);
c) level of risk during the task
The allowances to be made for these items will depend on the particular machinery concerned and its
application.
Annex A gives the application on how to apply this European standard in practice.
Annex B gives information on the use of notations for dimensions and anthropometric measurements.
4 Passage openings
A passage opening is an opening which allows the movement or the entry of a person's entire body, to enable
the person to carry out measures such as operating of control actuators, monitoring of work processes and
inspection of work results.
This European Standard specifies minimum, not optimum, dimensions for openings. Wherever possible from
the safety point of view the dimensions should be increased.
Furthermore, passage openings should be sufficiently large to allow rapid egress in the event of danger.
The allowances x and y in sub-clauses 4.1 to 4.5 are given in annex A. The values for a , h etc. are given in
