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
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This second edition cancels and replaces the first edition (ISO 11393-4:2003), which has been
technically revised. The main changes compared to the previous edition are as follows:
— in the Introduction, the term “hand-held chainsaws primarily constructed for cutting wood” has
been added;
— the normative references have been updated;
— the terms and definitions 3.11, 3.12 and 3.13 have been added;
— in Clause 4, two types have been defined and 4.4 has been added;
— in 5.1, Table 3 has been revised;
— the original Clause 7 has been deleted and a new Clause 7 has been specified;
— in Clause 8, 8.2.2 has been added and 8.3 has been revised;
— in 9.2, a test procedure has been added;
— in 5.4 and Clauses 6, 8, 10, 11 and 12 the definitions have been specified;
— A.4 has been added.

ISO 11393-4:2018(E)
Introduction
This document forms part of a series concerned with personal protective equipment (PPE) designed
to protect against the risks arising from the use of hand-held chainsaws primarily constructed for
cutting wood.
In some areas of work with chainsaws, one third of injuries occur to the hands. However, with different
working practices few hand injuries occur. Accidents occur due to a number of complex reasons, but a
common factor is incorrect use of the chainsaw. The importance of correct training and proper use of a
chainsaw in preventing accidents cannot be underestimated.
In some countries, chainsaw users adopt working practices that, together with training, make the use
of chainsaw protective gloves unnecessary. These usually include the instruction to hold the chainsaw
with both hands and to use the chain brake if it becomes necessary to stop cutting and clear away
branches, etc.
All parts of the hand (palm, back and fingers) have been shown to be at risk when using a chainsaw.
It is generally accepted for ergonomic and health and safety reasons that protecting the palm and
the underside of the fingers is not practicable. Neither is it possible to adequately protect the back
of the fingers unless a mitt is used. In this document, specifications for the protective coverage and
performance of the back of the right-hand glove and the left-hand glove are given.
For certain operations, such as tree surgery from lifts or platforms, chainsaw operators may be assisted
by other workers who also require protection from the chainsaw, particularly for their hands. The
gloves specified in this document are suitable for these workers too.
Further information is provided in Annex A on risk analysis, glove ergonomics and selection.
No PPE can ensure a 100 % protection against cutting from a hand-held chainsaw. Nevertheless,
experience has shown that it is possible to design PPE that offers a certain degree of protection. As
far as is known, all chainsaws are designed for right-handed use and, therefore, all protective clothing
designs and requirements have assumed right-handed use. Protection may not be adequate for left-
handed use.
Different functional principles may be applied in order to give protection. These include:
a) chain slipping: on contact the chain does not cut the material;
b) clogging: fibres are drawn by the chain into the drive sprocket and block chain movement;
c) chain braking: fibres have a high resistance to cutting and absorb rotational energy, thereby
reducing the chain speed.
Often more than one principle is applied in chainsaw protective clothing. It should be noted, however,
that none has yet been shown to be fully effective in gloves.

Two different types of gloves are specified by this document. Type 1 gloves include cut protection

doesn’t include protection against hand-held chainsaws.
Within those types, two designs of chainsaw protective gloves are considered: design A and design B.
Design A and design B have different specified protective areas as defined in 4.2 and 4.3, respectively.
