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

Introduction
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 personal
protective equipment (PPE) is required to be light, 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.
It is important to train firefighters 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.
This document provides minimum performance requirements for wildland firefighters' personal
protective equipment (PPE) face and eye protection, designed for use for extended periods during
wildland firefighting.
INTERNATIONAL STANDARD ISO 16073-7:2019(E)
Wildland firefighting personal protective equipment —
Requirements and test methods —
Part 7:
Face and eye protection
1 Scope
This document specifies the minimum performance requirements and methods of test for personal
protective equipment (PPE) face and eye protection, for wildland firefighting.
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 PPE for structural firefighting (see ISO 11999 series), for use against
chemical, biological, radiological and nuclear hazards, or for use where a reflective outer surface is
required (see ISO 15538).
Activities in support of wildland firefighting, such as the cutting of trees and the use of a chainsaw can
require additional protection to that provided in this document. Users are directed to those relevant
standards for the requirements associated with such protection.

4 Eye protectors
4.1 General
Wildland firefighters' eyes are exposed to irritants, such as smoke particles and off-gassing chemicals,
which cause severe irritation and discomfort to the eyes. Eye protectors should protect the eyes from
the ingress of smoke particles and other irritants. The complete eye protector should also resist fogging.
Activities associated with wildland firefighting, such as chainsaw use, may require alternative forms of
eye protection, such as mesh visors.
Eye protectors may need to interface with other items of PPE used for wildland firefighting, e.g. Helmet.
NOTE For more information, see ISO/TS 11999-2.
4.2 Design and manufacturing requirements
4.2.1 General construction
Eye protectors shall be free from projections, sharp edges or other defects, which are likely to cause
discomfort or injury during use.
4.2.2 Materials
No part of the eye protector in contact with the wearer shall be made of materials that are known to
cause any skin irritation.
