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

Introduction
This document provides minimum performance requirements for wildland firefighters' personal
protective equipment (PPE) firehoods, designed for use for extended periods during wildland
firefighting.
Wildland firefighting involves work carried out mostly in summer temperatures and for many hours,
during which the firefighter can develop high levels of metabolic heat. As a consequence, the PPE is
required to be of low mass, flexible and commensurate with the risks to which the firefighter can be
exposed in order to be effective without introducing excessive heat stress to the wearer.
Firefighters should be trained in the selection, use, care and maintenance of the PPE covered by this
document, including an understanding of its limitations.
It is intended that a risk assessment be undertaken to determine if the PPE covered by this document is
suitable for its intended use and the expected exposure.

Part 9:
Firehoods
1 Scope
This document specifies the minimum performance requirements and methods of test for firehoods
that cover the head and neck and are used for wildland firefighting. An optional requirement has been
included to provide limited protection against particulate contaminants
This document covers the general design of the PPE, the minimum levels of performance for the
materials employed and the methods of test used. This PPE is not intended to provide protection during
fire entrapment.
This document does not cover firehoods for structural firefighting (see ISO 11999-9). This document
only applies in situations when compatible protective clothing, helmet, and when necessary respiratory
protection devices are also worn.
