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

Introduction
In a world where there is an ever-increasing focus on worker occupational health and safety, fire services are
faced with the dilemma of trying to provide firefighters with as safe a work environment as is reasonably
possible whilst also having to deal with the ever-increasing risks our firefighters face whilst fighting fires in
both the urban, rural, industrial and wildland environments.
In the course of their duties, firefighters are exposed to many hazardous chemicals and carcinogens that
include smoke, soot, and the products of combustion such as heavy metals, benzene, perfluoroalkyl and
polyfluoroalkyl substances (PFASs) which are inhaled, ingested and/or, dermally absorbed, or both.
With the recent statement by the World Health Organization (WHO) elevating the classification of
occupational exposure as a firefighter to Group 1, ISO TC94 /SC14 Project Group on contaminates are taking
all possible steps to reduce the exposures to firefighters by reviewing all standards pertaining to PPE used by
firefighters and making recommendations to address identified shortfalls.
The following is an extract from the statement released by the WHO:
— — International Agency for Research on Cancer (IARC), the cancer agency of the World Health
Organization (WHO), has evaluated the carcinogenicity of occupational exposure as a firefighter
— — A Working Group of 25 international experts, including 3 Invited Specialists, from 8 countries was
convened by the IARC Monographs program for a meeting in Lyon
— — After thoroughly reviewing the available scientific literature, the Working Group classified
occupational exposure as a firefighter as carcinogenic to humans (Group 1), on the basis of sufficient
evidence for cancer in humans.
ISO/TR 21808 provides guidance on how to carry out a risk assessment, the guideline wasguidelines were
developed previously based on the work of CEN Technical Committee TC 162, Joint Working Group for
firefighters personal protective equipment and has been modified to encompass PPE worn by all emergency
service personnel.”.
During incidents being undertaken by emergency service personnel, many different hazards may be
encountered, including exposures to a range of chemicals that are biproducts of fires occurring in the urban
and wildland environment. Where possible, the level of risk that each hazard presents to firefighters is tomust
be eliminated or reduced to an acceptable level. The guidance given in ISO /TR/ 21808 indicates how to carry
out a risk assessment by acknowledging the hazards that may be present, the likelihood of the firefighters
becoming exposed to them and possible consequence of such exposure if not addressed.
This document provides minimum design and performance requirements for respiratory protective devices
(RPD) worn by firefighters, by referencing requirements of ISO 17420-5 which will reduce injury and loss of
life whilst fighting fires occurring in structures. Amongst other hazards faced by firefighters is exposure to
high thermal loads, flames, particulates and other hazardous chemicals.
This document forms part of the ISO 11999 series, ISO 11999-2, specifies design and performance
requirements to achieve compatibility across the PPE covered in parts ISO 11999-3 to ISO 11999-10, when all
the items are worn together, thereby creating a PPE ensemble, whether sold by a manufacturer or composed
by a user. In either case, the PPE ensemble should meet the requirements of ISO 11999-2. This becomes
significantly important when considering the issue of particulate protection and potential health risks posed
to firefighters from exposure to products of combustion.
This document supports the structure identified in ISO 11999-1 for a harmonised approach across all parts of
this series by setting single minimum design and performance requirements for PPE, including optional
requirements where identified, and for product markings and manufacturer’s instructions. Selection of an
v
appropriate system of PPE is dependent upon an effective risk assessment which identifies the hazards to be
faced, evaluates the likelihood of those ha
