ISO 16073-9:2020(E)
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.

4 General design requirements
4.1 General

Materials used in the construction of the firehood shall meet all requirements of ISO 13688, including

specifically the requirements for innocuousness in 4.2.
4.2 Firehood flexibility and facial opening

The firehood shall have flexibility to take up the shape of the wearer's head without discomfort and

shall not restrict head movement.

The firehood shall fit around, when possible, the respiratory protection devices for which compatibility

is claimed by the manufacturer without reducing the field of view or interfering with the breathing

function of the mask and give no discomfort to the wearer.
NOTE 1 Firehoods do not fit around P2 masks, check compatibility.

The design requirements specified shall be verified by visual inspection during the procedures in

Annex A.
NOTE 2 For more information on compatibility, see ISO/TS 11999-2.
4.3 Yoke interface area

The firehood shall have a yoke creating an interface area with protective clothing (see ISO 15384), the

integrity of which shall be maintained.
NOTE For more information on compatibility, see ISO/TS 11999-2.
4.4 Sizing

The firehood may be manufactured in various sizes. It shall be sufficiently elastic to be compatible with

various head sizes and shapes. Assess by visual inspection.

NOTE 1 Overstretching will reduce the heat protective performance of the firehood and is to be avoided by

design. Excess material in the construction of the firehood can hamper the wearer and compromise the wearing

of other personal protective equipment.

NOTE 2 The yoke is not always symmetrical on the back, upper shoulders and front (upper chest).

---------------------- Page: 7 ----------------------
ISO 16073-9:2020(E)
4.5 Seam construction

Seams shall be constructed to give minimum loss of strength and protection and to maintain the

temperature resistance and the integrity of the fire hood meeting the requirements of 6.2 and 6.7. Also

assess by visual observation as detailed in Annex A.
4.6 Labels

The label(s) for the marking requirement shall be positioned in the area defined as the yoke of the

firehood. Assess by visual inspection.
4.7 Particulate protection (Optional)

The firehood shall meet the requirements in 6.9 and the requirements in this sub-clause.

The particulate protection surface shall include from the top of the head to at least the areas from

50 mm below the side neck point, 100 mm below the front neck point and 100 mm below the back neck

point (neck points as defined in ISO 8559-1) (see Figure 1).

The elastic and stitching around the facial opening shall be permitted to exclude particulate blocking

material specifically for meeting the requirements of 4.2 for a distance of 20 mm from the leading edge

of the firehood face opening to the innermost row of stitching. The distance shall be measured in at

least six locations with the firehood lying on a flat surface with the face opening facing upwards.

2 particulate protected area

If the requirements of this subclause are met, add on the label wording equivalent to “This firehood

provides limited particulate protection" [see also 7.3 h)].

ISO 16073-9:2020(E)
5 Sampling and pre-treatment
5.1 Sampling

A sample shall be taken, which is representative of the materials used to construct the firehood taking

into account whether 4.7 applies.
5.2 Pre-treatment by cleaning

Where required in this standard, tests shall be carried out after five cleaning cycles (a cleaning cycle is

one wash and one dry cycle), cleaning shall be performed in accordance with ISO 6330 using the front-

loading horizontal drum machine and reference detergent 3 (ECE reference detergent 98).

Washing shall be carried out in accordance with ISO 6330 procedure 6N (60 ± 3) °C and drying by

procedure F (machine Type A1) exhaust temperature normal (minimum 40 °C, maximum 80 °C), unless

otherwise specified in the care labelling.
