ISO 18639-1:2018(E)
Introduction

ISO 18639 series of standards specify requirements of personal protective equipment (PPE) specifically

designed to protect firefighters from injury and/or loss of life while engaged in special rescue activities.

This document specifies the organisational structure of the ISO 18639 series of standards (see Annex A)

with common standard design for easier end user access (see Annex B for ISO 18639-3 onward) and the

drafting structure to be used consistently in the individual standards within the ISO 18639 series.

ISO/TS 11999-2 specifies design and performance requirements for the compatibility of the relevant

parts of the ISO 18639 series when all or some of the items covered in these parts are worn together,

thereby creating an ensemble standard. All items meet the general requirements for marking

and manufacturer’s instructions detailed in this document, as well as the specific marking and

manufacturer’s instructions of the respective parts.

Under best practice health and safety procedures, prior to choosing any PPE, a risk assessment of the

workplace is carried out. Where hazards are identified and cannot be removed from a work place, the items

of PPE chosen to protect personnel need to be fit for their intended use. They need to protect personnel

whilst allowing them to carry out the work required in their workplace without unduly increasing the

risk. In environments where firefighters can be required to work, not only needs the PPE protect the

firefighter whilst enabling them to achieve the objectives of attendance at an incident, but it also needs

safeguard them and allow a safe escape in the event that this becomes necessary. The risk assessment

is the responsibility of the firefighting organisation that is purchasing the PPE. The PPE chosen will also

allow the firefighter to carry out their duties without undue stress being caused by the PPE.

Some PPE, particularly PPE to protect against mortal danger, may have failure levels far above the

limit of exposures of human beings. In situations such as this, it is important to ensure that proper and

suitable safety procedures are in place that will both identify when personnel should be withdrawn

from dangerous or potentially dangerous situations. In addition, they need to ensure that the relevant

medical support is available for firefighters when they exit the incident, if rehydration or any other

medical treatment is required.

As the risk assessment will dictate the performance parameters for the PPE, it is critical that decision-

makers have the necessary knowledge of the risks against which the PPE is designed to protect. In

addition, they also need to understand the limitations of the equipment. It is recommended that those

who make the decision on the choice of PPE for particular work places should be competent in their

knowledge and understanding of both the work place hazards and the PPE from which to choose, prior

to making these decisions, to ensure that informed decisions are taken.

Further detail on carrying out risk assessment to ascertain the type of PPE required to protect

personnel working in specific areas is included in Annex C of this document.

Hazards in the workplaces of firefighters are varied but may be common from workplace to workplace

therefore some uses of PPE for firefighters can be multi-purpose. Because this Standard has been

developed on a risk assessment approach, a number of different types, levels or classes are given for

certain performance requirements of various parts of a PPE ensemble.

ISO 18639 series includes separate parts for each item of a firefighter's ensemble. As PPE to protect

each part of the body can be so complex, this Standard draws from the expertise of other technical

Committees in ISO, which specialise in such protection.

The results of the risk assessment for certain work places may require the use of PPE with higher

and/or different levels or classes of performance than those in this Standard. PPE covered in this

document will not protect from all possible exposures. Nothing in this document is intended to restrict

any jurisdiction, purchaser or manufacturer from exceeding the minimum performance requirements

specified in this Standard.

ISO/TC 94/SC 14 was established in 2000 with the purpose of standardisation of the performance

of personal protective equipment (PPE) intended to safeguard firefighters against the hazards

ISO 18639-1:2018(E)

encountered in the performance of their duties. Two of the objectives of the ISO/TC 94/SC 14 Business

Plan are:

— to move away from prescriptive-based requirements in standards to a performance-based approach

incorporating a risk assessment in all areas of firefighters personal protective equipment, and

— to ensure wherever practical, compatibility, integration and consistency between the components

of firefighters PPE.

ISO/TC 94/SC 14 has developed a Technical Report on this subject, ISO/TR 21808. Firefighters are

trained in the selection, use, care and maintenance of their PPE. Firefighters need also to be trained in

the performance and limitation of their PPE.

PPE ensembles for firefighters undertaking specific rescue
activities —
Part 1:
General
1 Scope

ISO 18639 series of standards specify requirements of personal protective equipment (PPE) specifically

designed to protect firefighters from injury and/or loss of life while engaged in specific rescue activities.

ISO 18639 series provides the principles that govern the development of incident type and/or hazard

specific minimum test methods including design and performance requirements for personal protective

equipment (PPE) worn by firefighters and other rescue workers to reduce injury and/or the loss of life

while engaged in rescue activities.

To assist with selection based on a risk assessment (see Annex C), type of PPE, (if applicable) and

performance levels, for different categories of protection are included.

This document covers PPE for use in the rescue activities for road traffic crash (RTC) and urban search

and rescue (USAR), but could also include other rescue activities depending on the risk assessment.

It does not include PPE for use in high risk fire exposures.

Similarly, this document does not include PPE to protect against chemical and biological hazards, except

against short term and accidental exposures whilst engaged in rescue activities.

This document describes the general structure of the ISO 18639 series, including each subsection,

sets design and performance requirements for PPE and includes requirements for marking and

manufacturer’s instructions.

5 Design and performance requirements for PPE items and ensembles
5.1 PPE ensembles

An ensemble of PPE items is classified as meeting the requirements of this document, if every item in

the ensemble meets the appropriate requirements of the relevant parts of ISO 18639 series and provide

as an ensemble protection to the whole body of the firefighter for rescue operations.

For example, any item of PPE or any PPE ensemble, which are intended to provide protection for the

firefighter’s upper and lower torso, head, neck, arms, hands, legs and feet, shall be in accordance with

the requirements of relevant part of ISO 18639 series.

Nevertheless, an item of PPE, which is in accordance with the requirements of one of the relevant part

of ISO 18639 series, can individually be designated and marked for that item of PPE according to the

relevant part of the ISO 18639 series.
5.2 Combination of items of PPE

A PPE combination is the use of 2 or more PPE elements, each of which meets the requirements of the

relevant individual part of ISO the 18639 series but is not classed as an ensemble (see 5.1).

Annex C
(informative)
Information on risk assessment
C.1 General

Personal protective equipment is only one part of an effective system of firefighter safety. Well-trained,

closely supervised and properly staffed fire departments are equally essential elements of minimizing

the operational risk.

Regardless of location, the primary goals of rescue work are to control an incident as quickly as possible

and at the same time take steps to minimize eventual damage to and loss of persons and materials. In

order of priority, the objectives of a firefighter reaching an incident are to:
— save lives and to prevent or minimize injury;
— prevent or minimize damage to property;
— prevent or minimize damage to the environment.

The role of firefighters' personal protective equipment (PPE) is to protect the firefighter and to enable

the firefighter to achieve these objectives.

However, at an incident where the firefighter is unable to achieve these objectives, the PPE shall also

provide sufficient protection to enable the firefighter to escape whilst eliminating or minimising

the possibility of injury. The choice of PPE and the protection it offers shall be selected on the basis

of a risk assessment specific to the incidents and where hazards are identified and selecting specific

performance requirements for the PPE used which eliminate or reduce these hazard.

C.2 General approach for conducting a risk assessment
The three major steps of the risk assessment process are as follows.

1) Risk identification: for every aspect of the operation of the fire department or brigade, list

potential problems and hazards. The following are examples of sources of information that may be

useful in this process:
— a list of the risks to which members are or may be exposed;

— records of previous accidents, illnesses, and injuries, both locally and nationally and

internationally;
— facility and apparatus surveys, inspections, etc.

2) Risk evaluation: evaluate each item listed in the risk identification process using the following

questions.
— What is the level or potential severity of the occurrence?
— What is the potential frequency or likelihood of the occurrence?
— What are the potential consequences of the occurrence?
8 © ISO 2018 – All rights reserved
---------------------- Page: 14 ----------------------
ISO 18639-1:2018(E)

This will help to set priorities in the developing specifications for PPE performance. Some sources of

information which may be useful are:
— safety audits and inspection reports;
— prior accident, illness, and injury statistics;
— application of national data to local circumstances;
— professional judgement in evaluation risks unique to the jurisdiction.

3) Risk control: once the risks are identified and evaluated, a control for each should be implemented

and documented. The hazard controls in the hierarchy are, in order of decreasing effectiveness

represented in Figure C.1:
Figure C.1 — Hazard controls in the hierarchy
— Elimination

Eliminating the hazard—physically removing it—is the most effective hazard control. For example,

if employees shall work high above the ground, the hazard can be eliminated by moving the piece

they are working on to ground level to eliminate the need to work at heights.
— Substitution

Substitution, the second most effective hazard control, involves replacing something that produces

a hazard (similar to elimination) with something that does not produce a hazard.
To be an effective control, the new product shall not produce another hazard.
— Engineering

The third most effective means of controlling hazards is engineered controls. These do not

eliminate hazards, but rather isolate people from hazards.
— Administration

Administrative controls are changes to the way people work. Examples of administrative controls

include procedure changes, employee training, and installation of signs and warning labels (such

as those in the Workplace Hazardous Materials Information System. Administrative controls do

© ISO 2018 – All rights reserved 9
---------------------- Page: 15 ----------------------
ISO 18639-1:2018(E)

not remove hazards, but limit or prevent people's exposure to the hazards, such as completing road

construction at night when fewer people are driving.
— Personal protective equipment

PPE is often referred to as the Last Line of Defence. Additionally, some PPE in the Firefighting

service is designed to protect the firefighter from the unforseen event or exposure and better

facilitate their retreat to a safe place.

Firefighters often use some or a combination of all of these controls at emergency incidents.

In the case of PPE, this should include determining the appropriateness of specific tests and

requirements for eliminating or reducing risk. Normally, the two primary methods of controlling risk,

in order of preference, are as follows:

— wherever possible, totally eliminate and/or avoid the risk or activity that presents the risk;

— where it is not possible to or practical to avoid or eliminate the risk, steps should be taken to control it

— such as developing appropriate PPE specifications.

Specification of appropriate PPE shall be part of any overall safety program which includes Standard

Operating Procedures, training, and inspections. As with any program, it is important to evaluate

whether the plan is working. Periodic evaluations should be made, and if the program elements are not

working satisfactorily, then modifications to the program should be made. If the methods are changed,

a new risk assessment should be per
