Description

[0001] JACKET FOR FIREFIGHTERS

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to the field of flame-resistant protective clothing, more in particular to a jacket for firefighters. The present invention further relates to the use of a middle layer in a jacket according to the invention and to a kit of parts.

[0004] BACKGROUND OF THE INVENTION

[0005] Firefighters and other specialized personnel, such as first responders and rescue teams, are assigned to carry out diverse high-risk tasks during their interventions, each of which necessitates a different attire, the requirements of which are typically set out in official standards. These requirements for such personal protective equipment (PPE) thereby depend on the nature of the task or duty. Standards for protective clothing for firefighters have been set and focus among other things on heat and flame resistance, resistance to water penetration and to water vapour, and / or resistance to penetration by liquid chemicals. Standards may further include rules relating to mechanical properties of the garment (tear, tensile strength), inspection access, anti-wicking properties of the garment and the like. As a result, firefighter and rescue teams end up with a wide range of protective clothing, each suitable for a different set of tasks, wherein each item represents a significant cost and can only be used for a limited amount of duties.

[0006] It is known in the prior art to combine layers, each of which has a different set of properties, in an assembly to form a protective garment.

[0007] US 2008 / 0209611 Al discloses a garment outer shell and liner system, comprising a garment outer shell, a first liner having first protective properties and a second liner having second protective properties. Each liner is adapted to fit within, and is removably securable to, the outer shell. The liners each have a protruding portion, which is arranged to protrude from the outer shell when that respective liner is secured within the outer shell. The protruding portion of each of both liners has a colour which is different from each other. A shell can carry one single liner, but can also carry two liners at a single time.

[0008] EP 2 984 955 Al relates to a protective suit having a first outer fabric layer of a flame-resistant material, a second basic layer having a moisture barrier, and a third layer being heat resistant, wherein the second basic layer and the third layer are connected. The first outer fabric layer is detachably connected with the second basic layer by means of a connection means. When the first, second and third layer are worn together, the protective suit fulfils the requirements of EN 469:2005 / Al:2006. It is an object of this invention to allow the wearer to separate easily the first outer fabric layer from the second basic layer, when the first outer fabric layer has been contaminated during firefighting, without having to take off the second basic layer. When the contaminated outer layer has been removed, a new outer layer may easily be remounted outside the basic layer, so that the protective suit is ready for use again.

[0009] US 5 884332 relates to a firefighter garment including a liner inspection system which enables a firefighter to inspect the liner at any time to ensure that the waterproof sealing means of the liner is intact. The liner has a moisture barrier and a thermal barrier which are permanently connected to one another at the upper edge portions thereof, such upper edge portions also being detachably connected to the outer shell. The lower edge portions of the moisture barrier and the thermal barrier are detachably connected to one another only at spaced points in such a manner that they can be easily detached to gain access to the space between the moisture barrier and the thermal barrier.

[0010] It is a disadvantage of the protective garments and the combinations of layers as proposed in the above documents, that the user of such garments may be wearing unnecessary layers of protection during a mission. It is in the interest of the user of the jacket that the need for thermal protection and the risk for heat stress are carefully considered and balanced. Heat stress can lead to cramps, exhaustion or even a heat stroke. Hence, in interventions where little or no thermal protection is required, unnecessary layers providing such thermal protection will in reality only add to the total weight of the protective clothing while endangering the functioning, safety and wellbeing of the wearer.

[0011] Based on the above, there therefore is a need for a personal protective equipment (PPE), more in particular for a protective jacket, which jacket has to be adaptable by a minimal intervention to render it suitable for a multitude of high-risk tasks, wherein said adapted jacket meets the requirements of the standards required of clothing for such tasks, wherein investment costs may be reduced, and wherein said jacket further provides a maximum of comfort for the user, e.g. without imposing unnecessary layers. SUMMARY OF THE INVENTION

[0012] The inventors have surprisingly found that the jacket according to the present invention fulfills the above mentioned needs and overcomes the above mentioned disadvantages.

[0013] In an aspect of the present invention, there is provided a jacket for firefighters having a body portion or body and two sleeves, further having an outside and an inside, said jacket comprising, in the direction from the outside to the inside

[0014] • a flame-resistant, abrasion-resistant outer fabric layer; and

[0015] • a liner, which liner is permanently connected to said outer fabric layer; wherein the jacket further comprises a middle layer, which is adapted to fit in between said outer fabric layer and said liner, and which is removably securable to said outer fabric layer and said liner, and wherein at the distal ends of the sleeves, said middle layer has a wristlet portion, arranged to protrude from said outer fabric layer when the respective middle layer is applied and / or secured between said outer fabric layer and said liner.

[0016] It is an advantage of the present invention that the jacket, having an outer fabric layer and a liner, and optionally a deliberately selected middle layer, qualifies for a wide range of technical missions, including fighting forest fires, structural fires as well as interventions involving liquids under pressure. The assembly of a permanently connected liner and an outer fabric layer, with or without a middle layer, can thereby qualify for a variety of standards, as will be explained herein.

[0017] It is thereby an advantage that only a limited number of items making up the PPE or jacket are necessary for meeting such standards, which reduces the cost of investment in an adapted equipment for e.g. a fire brigade.

[0018] It is a further advantage of the present invention that a jacket as described herein is easy to handle.

[0019] In an embodiment of the jacket according to the invention, said jacket is provided with an opening on the inside of the jacket for inserting and applying said middle layer in between said outer fabric layer and said liner, which opening is closable by means of a first connection means, wherein said first connection means relates to at least one of a plurality of buttons, a plurality of press buttons, a plurality of magnets, a zipper and / or a hook-and- loop fastener.

[0020] It is an advantage of this embodiment that a middle layer can be applied in between an outer fabric layer and a liner, and taken out therefrom, via an opening which can be closed and opened. Furthermore, by providing the opening on the inside of the jacket, no connection means need to be provided on the outside of the outer fabric layer, which could then form an unnecessary element or protrusion that could get caught somewhere during an intervention, thereby impeding the user of the jacket in his or her intervention.

[0021] In an embodiment of the jacket according to the invention, said opening is located at the lower part of the back of the jacket, preferably along the bottom hem of the jacket, wherein said first connection means is a zipper.

[0022] Advantageously, an opening along the bottom hem has been found to be very easy to access, especially when said opening extends from one corner near the front zipper to the opposing corner near the front zipper. Furthermore, by placing the opening along the bottom hem, the user of the jacket will not feel the presence of the connection means, such as a zipper, on the inside of the jacket.

[0023] In an embodiment of the jacket according to the invention, said outer fabric layer is based on meta-aramid fibres; para-aramid fibres; polyamide-imide (PAI); phenylene benzobisoxazole (PBO) fibres, more in particular poly(p-phenylene-2,6-benzobisoxazole); polybenzimidazole (PBI) fibres; polyphenylene sulphide (PPS); polytetrafluoroethylene (PTFE); polyetherimide; TLCP fibres; melamine-formaldehyde fibres; wool; flame retardant (FR) viscose; carbon; or a mixture or blend thereof.

[0054] DETAILED DESCRIPTION

[0055] In the context of the present invention, the term "comprising" should not be interpreted as excluding features or elements other than those explicitly mentioned. It should be construed as specifying the presence of the features or elements indicated, but does not exclude the presence or addition of one or more other features or elements. Thus, the scope of the expression "a device comprising A and B" should not be limited to devices consisting only of A and B. Similarly, a composition comprising components A and B should not be limited to compositions consisting only of components A and B. Accordingly, the terms "comprising" and "including" encompass the terms more restrictive "consisting essentially of" and "consisting of".

[0056] In the context of the present invention, if an element or component is said to be selected from a list of recited elements or components, it should be understood that the element or component can also be any one of the individual recited elements or components in said list, or can also be selected from a group consisting of any two or more of the explicitly listed elements or components.

[0057] Further advantages and characteristics of the invention will become apparent from the following description of a number of preferred embodiments of protective clothing according to the invention. However, the following description is merely illustrative and is not intended to limit the scope of the invention as determined by the claims.

[0058] An aspect of the invention relates to a jacket for firefighters. The jacket according to the invention can be used in technical demanding interventions, such as performed by firefighters, first responders and / or rescue teams, which interventions may include, but are not limited to structural firefighting, wildland firefighting, rescue operations, as well as operations involving the containment, decontamination and clean-up of chemical products, said products being possibly under pressure. Structural firefighting relates herein to the activities of rescue, fire suppression, and property conservation in buildings, enclosed structures, or properties that are involved in a fire or emergency-situation. Wildland firefighting is related to suppression of wildfires, wherein the term "wildfire" relates to uncontrolled and unplanned fire in an area of combustible vegetation. Wildland firefighting typically requires different techniques and equipment than those used in structural firefighting.

[0059] The invention is based inter alia on the insight that a removable middle layer, which is placed in between an outer fabric layer and an inner liner of a jacket and is removably securable thereto and which middle layer is further interchangeable or exchangeable with another type of middle layer having different properties, can provide specific properties so that the assembly of layers qualifies for a certain standard. By providing an outer layer in a permanent connection with a liner, without a middle layer, a jacket is obtained which may qualify for and be used for wildland firefighting, as will be explained herein. The liner contributes herein to the necessary technical properties and provides for comfort for the user of the jacket. Like the outer layer, the liner must be durable. After all, the liner faces the user's body and provides comfort by protecting the user against the abrasive-resistant character of the outer layer. The invention is further based on the insight that the overall cost of the PPE can be reduced by permanently connecting the expensive, durable and / or essential parts of the jacket, being the liner and outer layer, while applying, if need be, the exchangeable and disposable parts, such as the variety of middle layers, therein between.

[0060] The jacket for firefighters as described herein may be sold, packaged and / or provided with at least one separate middle layer, wherein said middle layer is adapted to fit in between an outer fabric layer and a liner of the jacket. More in particular, the jacket may be sold or provided with two or more separate middle layers, which middle layers can each have a different set of thermal and / or moisture resistant properties. Said two or more separate middle layers may thereby be interchangeable or exchangeable.

[0061] The middle layer can have a set of such properties so that when applied in between said outer fabric layer and said liner and thus worn in combination, the assembly of the three different layers (outer fabric layer, middle layer and liner) provides a certain protection for the wearer of the jacket and meets the requirements of a particular standard. As an example, depending on the type of middle layer applied, said jacket can meet the requirements of the EN 469:2020 standard, thereby qualifying the jacket for use in fighting structural fires, possibly involving liquids under pressure.

[0062] The European standard EN 469:2020 relates to minimum performance requirements for protective clothing designed to be worn during firefighting activities. Distinction is made between firefighting activities by dividing them into two performance levels, wherein Level 1 specifies the minimum requirements for firefighting clothing involving work associated with outdoor firefighting and their support activities, and Level 2 specifies the minimum requirements for firefighting clothing for risks encountered in fighting fires and rescue from fire in structures. The distinction between Level 1 and Level 2 clothing depends solely on the requirements for heat and flame (XI for Level 1; X2 for Level 2). The standard further contains additional marking providing two grades of protection against water penetration (Y1 or Y2 depending on the degree of protection, wherein Y2 provides increased protection) and water vapour resistance (Z1 or Z2 depending on the degree of water vapour resistance, wherein Z2 provides decreased resistance to water vapour).

[0063] According to an aspect of the invention, there is provided a jacket for firefighters having a body and two sleeves, further having an outside and an inside, said jacket comprising, in the direction from the outside to the inside

[0064] • a flame-resistant, abrasion-resistant outer fabric layer; and

[0065] • a liner, which liner is permanently connected to said outer fabric layer; wherein the jacket further comprises a middle layer, which is adapted to fit in between said outer fabric layer and said liner, and which is removably securable to said outer fabric layer and said liner, and wherein at the distal end of the sleeve, said middle layer has a wristlet portion, arranged to protrude from said outer fabric layer when the respective middle layer is applied and / or secured between said outer fabric layer and said liner.

[0068] In embodiments of the jacket according to the invention, the jacket 10 has a storm flap or front flap 12, for covering said front zipper 11, which front flap 12 is typically part of or made of the same material as the outer fabric layer 20.

[0069] In embodiments of the jacket according to the invention, said jacket 10 has at least one of the following elements: a pocket, a bellow pocket and / or a sleeve pocket. Said elements may be applied onto the outside of the outer fabric layer 20 or may be internal to the jacket, but accessible from the outside of the jacket 10. In embodiments according to the invention, the jacket 10 contains or is partly covered by a fluorescent or reflective material 13, such as fluorescent strips or reflective trim. Preferably, said fluorescent or reflective material 13 is attached on its outer fabric layer 20, on the body part 17 of the jacket 10 and / or the sleeves 18. Furthermore, said jacket 10 can have visual indicia, such as text imprinted or embroidered on its outer fabric layer 20, on the body part 17 and / or the sleeves 18. Furthermore, said jacket can have reinforced elbow areas 14.

[0070] In embodiments according to the invention, said jacket 10 has a detachable hood (not shown on the figures). In embodiments, said hood has preferably a same assembly of layers as discussed herein. More in particular, said hood may comprise, from the outside to the inside a flame-resistant, abrasion-resistant outer fabric layer and a liner, as described herein. In embodiments, said hood can contain a middle layer in between said outer fabric layer and said liner, said middle layer being any one of the middle layers as described herein. More in particular, said middle layer may relate to a thermal barrier, or a thermal barrier and a moisture barrier; said middle layer may further contain a filter layer, e.g. comprising active carbon, or a particulate barrier. Preferably, said middle layer is permanently connected to said outer fabric layer and said liner for said hood and / or permanently applied in between both layers. In embodiments of the hood according to the invention, said hood and / or said jacket 10 may contain a connection element for detachably connecting said hood and said jacket, said connection element preferably comprising at least one of: a plurality of buttons, a plurality of press buttons, a plurality of magnets, a zipper and / or a hook-and-loop fastener.

[0071] The jacket has an outside 15 and an inside 16 and comprises, in the direction from the outside 15 to the inside 16 a flame-resistant, abrasion-resistant outer fabric layer 20 and a liner 40.

[0072] For the purpose of the invention, the term "flame-resistant" as used herein is intended to mean, in particular, that the flame directed to the inside or the outside of the clothing or of the material which is flame-resistant, is not propagated by the clothing or by said material. It will be understood that for both the outer fabric layer 20 and the liner 40, a flame propagation index or flames spread index of 3 is achieved, measured according to the European standard EN ISO 15025:2016, procedure A. More in particular, each of said layers has a flame spread index 3 according to EN ISO 14116:2015.

[0073] For the purpose of the invention, the term "abrasion-resistant" as used herein is intended to mean that the clothing does not wear too quickly due to use or washing. The abrasion or wear resistance of textile materials is measured with an abrasion test device, also known as a Martindale tester. Herein, the textile material is rubbed against a standard abrasive at a predetermined pressure and according to a continuous variable movement. The standard abrasive material is a wool fabric. The pressure is selected depending on the application and / or the requirements of the final article, being either 9 kPa or 12 kPa. The result is expressed as the number of cycles of resistance, wherein, in the textile industry of personal protective clothing, the end point of the test is usually taken to be the rupture of two threads. In the present description, the term "an abrasion resistant layer" is intended to mean, in particular, a layer which resists for at least 50000 cycles at a pressure of 12 kPa (until two threads are broken).

[0074] The liner 40 is permanently connected to said outer fabric layer 20.

[0075] In embodiments according to the invention, said liner 40 is sewn or stitched to said outer fabric layer 20, thereby securing a permanent connection between the two layers. Said permanent connection, which thus comprises a seam, will typically be provided at least partly along the edge of said outer fabric layer 20 and said liner 40. Preferably, said liner 40 is sewn or stitched to said outer fabric layer 20 at least at the collar portion and / or shoulder portions of the jacket 10, thereby securing a permanent connection between the two.

[0112] In embodiments of the jacket according to the invention, said liner 40 comprises or contains reinforcing filaments. More in particular, any material forming a liner 40 as described here above, may be formed around such reinforcing filaments. Preferably, said reinforcing filaments contain or relate to a polyester material.

[0113] In embodiments of the jacket 10 according to the invention, said liner 40 relates to a single woven layer.

[0114] In alternative embodiments of the jacket according to the invention, said liner 40 relates to a special woven layer, more in particular to a double woven layer, wherein said special woven layer is configured to have one material, or two or more materials, such as a three dimensional woven layer made of one or two or more materials, interconnected to form said special woven layer, wherein each material has an equal, similar or a different composition. In preferred embodiments, said liner relates to a fabric, e.g. such as disclosed in EP 3 165 258 Bl, wherein said fabric preferably comprises strips having a flat fabric structure, alternating with strips where the fabric is doubled to form air channels. These air channels can have, in particular, a width which is comprised between 2 and 10 mm and more preferably between 3 and 8 mm. The strips between the air channels preferably have a width which is comprised between 1 and 10 mm and preferably between 1 and 6 mm.

[0115] The jacket 10 further comprises a middle layer 30, which is adapted to fit in between said outer fabric layer 20 and said liner 40. For fitting in easily between said two layers 20,40, the middle layer 30 may have substantially the same size and / or shape as both of said layers 20,40.

[0116] The jacket 10 is configured to contain maximum only one middle layer 30 at a time. In other words, if used, only one single middle layer 30 can be applied in between said outer fabric layer 20 and said liner 40, and worn by the user, at a time.

[0117] The middle layer 30 is configured to be removably securable to said outer fabric layer 20 and said liner 40, meaning that the middle layer 30 can be connected or secured to said outer fabric layer 20 and said liner 40 in a detachable manner.

[0118] The middle layer 30 has or is provided with wristlet portions 31, which wristlet portions 31 are situated at the distal end of the sleeves 18. For the purpose of the invention, the term "wristlet" refers herein to a lose-fitting knitted band which is attached to the end of the sleeve portion formed by the middle layer 30.

[0119] Said wristlet portion 31 is arranged to protrude from the outer fabric layer 20 when the respective middle layer 30 is secured between said outer fabric layer 20 and said liner 40. Hence, the wristlet portion 31 is noticeable when the middle layer 30 is applied between said two layers 20,40. In other words, when wearing the jacket 10 with the wristlet portion, the wearer or user of the jacket 10 or a bystander will be capable of noticing the presence and appearance of the wristlet.

[0120] In embodiments of the jacket according to the invention, said wristlet portion 31 may contain a means of identification (not shown on the figures) with regard to the type of middle layer 30 that has been applied between the outer fabric layer 20 and the liner 40. Said means of identification may be a visual indication, such as a colour, a text or number imprinted or embroidered on the wristlet portion 31, and the like.

[0121] As mentioned here above, a middle layer 30 may relate to a fabric layer providing a thermal barrier. A middle layer 30 may also relate to a fabric layer providing a thermal barrier and, in addition, a moisture barrier. A middle layer 30 may also relate to a fabric layer providing a thermal barrier in some sections of the layer 30 and, in addition, a thermal barrier and a moisture barrier in other sections of the layer 30. A middle layer 30 may also relate to a fabric layer providing a filter layer, said filter layer comprising e.g. an active carbon layer. Middle layers 30 that are suitable for being applied within the layers 20,40 and fit therein between may thus have a same or similar size, shape and / or appearance, but may differ in performance and materials characteristics.

[0122] In embodiments of the jacket according to the invention, said middle layer 30 relates to a fabric layer providing a thermal barrier.

[0123] As determined by EN 469:2020, contact heat, tested according to EN ISO 12127- 1:2015 with a contact temperature of 250°, should have a threshold time of at least 10 seconds (=level 2 or X2).

[0126] Furthermore, as determined by EN 469:2020, the resistance to water vapour (Ret), measured according to EN ISO 11092:2014, should be below or equal to 30 m2Pa / W (= level 2 or Z2).

[0127] Furthermore, as determined by EN 469:2020, the resistance to water penetration, tested according to EN ISO 811:2018 with a pressure increase rate of 0.98 kPa / min, should be less than 20 kPa (= level 1 or Yl) due to the absence of the moisture barrier.

[0128] Accordingly, in the present description, the term "middle layer 30 relating to a fabric layer providing a thermal barrier" and similar expressions is intended to mean, in the further absence of a moisture barrier, in particular a middle layer which insures that the resistance to heat and flame fulfils level 2 (X2) according to EN469:2020, and the resistance against water vapour resistance fulfils level 2 (Z2) according to EN 469:2020. However, it will be appreciated that the resistance to water penetration according to EN 469:2020 fulfils level 1 (Yl).

[0129] Hence, a jacket 10 being provided with a middle layer 30 which relates to a fabric layer providing a thermal barrier (and hence in the absence of a moisture barrier) can meet the requirements of EN 469:2020, having a level X2 Yl Z2. As a consequence, said jacket 10 has a performance grade Yl < 20 kPa, with respect to the norm EN 469:2020.

[0132] In embodiments of the jacket according to the invention, said fabric layer relating to said middle layer 30 also provides a moisture barrier, further to a thermal barrier, wherein said thermal barrier may be a thermal barrier as described hereabove. Hence, it will be understood that a middle layer 30 according to such embodiments relates to a fabric layer providing a thermal barrier and a moisture barrier.

[0133] It will be appreciated that, due to the presence of a thermal barrier as described here above, the resistance to heat and flame fulfils level 2 (X2) according to EN469:2020.

[0134] The middle layer relating to a fabric layer providing a thermal barrier and additionally a moisture barrier, ensures that no water penetrates through the assembly of layers and therefore through the jacket 10, while still allowing water vapour to escape through the protective clothing. As determined by EN 469:2020, the resistance to water penetration, tested according to EN ISO 811:2018 with a pressure increase rate of 0.98 kPa / min, should be at least 20 kPa (= level 2 or Y2) due to the presence of the moisture barrier.

[0135] Furthermore, as determined by EN 469:2020, the resistance to water vapour (Ret), measured according to EN ISO 11092:2014, should below or equal to 30 m2Pa / W (= level 2 or Z2).

[0136] Accordingly, in the present description, the term "middle layer 30 relating to a fabric layer providing a thermal barrier and a moisture barrier" and similar expressions is intended to mean, in particular, a middle layer which insures that the resistance to water penetration of the assembly of layers and therefore the jacket 10, fulfils level 2 (Y2) according to EN469:2020, the resistance against water vapour resistance fulfils level 2 (Z2) according to EN 469:2020, and the resistance to heat and flame fulfils level 2 (X2) according to EN 469:2020.

As a consequence, said jacket 10 has a performance grade Y2 > 20 kPa, with respect to the norm EN 469:2020.

[0145] In embodiments of the jacket according to the invention, said middle layer 30 relates to a fabric layer providing a thermal barrier in first sections of the layer 30 and a thermal barrier and a moisture barrier in second sections of the layer 30.

[0146] In preferred embodiments of the jacket according to the invention, said first sections being provided only with a thermal barrier may relate to portions of the middle layer 30 covering at least part of the back of the user.

[0147] It will be appreciated that, due to the presence of a thermal barrier as described here above, the resistance to heat and flame fulfils level 2 (X2) according to EN469:2020. Furthermore, as determined by EN 469:2020, the resistance to water vapour (Ret), measured according to EN ISO 11092:2014, should be below or equal to 30 m2Pa / W (= level 2 or Z2).

[0148] Furthermore, as determined by EN 469:2020, the resistance to water penetration, tested according to EN ISO 811:2018 with a pressure increase rate of 0.98 kPa / min, should be less than 20 kPa (= level 1 or Yl) due to the partial absence of the moisture barrier.

[0149] Accordingly, in the present description, the term "middle layer 30 relating to a fabric layer providing a thermal barrier in first sections of the layer and a thermal barrier and a moisture barrier in second sections of the layer" and similar expressions is intended to mean, in the further partial absence of a moisture barrier, in particular a middle layer which insures that the resistance to heat and flame fulfils level 2 (X2) according to EN 469:2020, and the resistance against water vapour resistance fulfils level 2 (Z2) according to EN 469:2020.

[0154] It will be appreciated that, due to the presence of a thermal barrier as described here above, the resistance to heat and flame fulfils level 2 (X2) according to EN 469:2020. Furthermore, as determined by EN 469:2020, the resistance to water vapour (Ret), measured according to EN ISO 11092:2014, should be below or equal to 30 m2Pa / W (= level 2 or Z2).

[0157] Hence, a jacket 10 being provided with a middle layer 30 which relates to a fabric layer providing a thermal barrier (and hence in the absence of a moisture barrier) can meet the requirements of EN 469:2020, having a level X2 Yl Z2. As a consequence, said jacket 10 has a performance grade Yl < 20 kPa, with respect to the norm EN469:2020.

[0158] The thermal barrier may be provided by one of the materials cited here above for a middle layer 30 relating to a fabric layer providing a thermal barrier.

[0159] In embodiments of the jacket according to the invention, said middle layer 30 relates to a fabric layer providing a thermal barrier further comprising a filtration capacity based on active carbon.

[0160] It will be appreciated that, due to the presence of a thermal barrier as described here above, the resistance to heat and flame fulfils level 2 (X2) according to EN 469:2020.

However, it will be appreciated that the resistance to water penetration according to EN 469:2020 fulfils level 1 (Yl).

[0163] Hence, a jacket 10 being provided with a middle layer 30 which relates to a fabric layer providing a thermal barrier (and hence in the absence of a moisture barrier) can meet the requirements of EN 469:2020, having a level X2 Yl Z2. As a consequence, said jacket 10 has a performance grade Yl < 20 kPa, with respect to the norm EN 469:2020.

[0165] In embodiments of the jacket 10 according to the invention, middle layers 30 are interchangeable or exchangeable. In a practical everyday application, a firefighter who is mobilized for an assignment, can exchange a middle layer 30, providing certain thermal and moisture repellent properties, for another middle layer 30, having a different set of properties. Hence, a middle layer 30 meeting the requirements of EN 469:2020, having a level X2 Yl Z2 can be exchanged for a middle layer meeting the requirements of EN 469:2020, having a level X2 Y2 Z2. Likewise, a middle layer 30 meeting the requirements of EN 469:2020, having a level X2 Y2 Z2 can be exchanged for a middle layer meeting the requirements of EN 469:2020, having a level X2 Yl Z2. In embodiments, exchanging middle layers 30 can be accompanied by exchanging hoods, e.g. by removably attaching a hood having a similar composition as the assembly forming the jacket 10, more in particular by having a similar type of middle layer 30 in said hood.

[0166] As explained hereabove, the amount of jackets 10 per firefighter can as a consequence be limited to a minimum. There is therefore no need to purchase for each firefighter a different type of jacket for each particular type of assignment.

[0167] It is an advantage of the invention, that in line with the nature of the intervention, and the risks associated therewith, a particular type of middle layer 30 may be applied or omitted in between the layers 20,40, which results in the user of the jacket 10 being appropriately protected for the task, so that one single jacket 10 according to the invention qualifies for a large variety of interventions.

[0168] In embodiments of the jacket according to the invention, no middle layer 30 is applied in between said outer fabric layer 20 and said liner 40. It has been found that the jacket 10, without the middle layer 30, can have a set of such properties so that it provides a certain protection for the wearer of the jacket and meets the requirements of the standard EN ISO 15384:2020 / Al:2021, thereby qualifying the jacket for use in fighting wildfires. The European standard EN ISO 15384:2020 / Al:2021 relates to minimum performance requirements for protective clothing designed to be worn during wildland firefighting and associated activities.
