Space Jackets Down to Earth 87

Roland Piquepaille writes "Several technologies used to design the space suits protecting astronauts are now being adapted to protect workers facing extremely hot and dangerous conditions. According to the European Space Agency (ESA), these 'space-cooled' jackets are using three different technologies: special 3D-textile structure, cooling apparatus derived from astronauts' suits, and a special water-binding polymer acting as a coating. Even if these protective clothes are primarily intended for firefighters or steel workers, several applications are possible, such as in sportswear or in cars as parts of air conditioning systems.

      How are you defining 'regular clothes'?

      Indeed, it is likely we will see clothing such as this used by firefighters quite soon, for instance. While that isn't everybody, it would start to bring such textiles into everyday usage.

      If such materials are too expensive to be used for consumer-grade clothing, we may initially see it used for items such as cooking gloves. Eventually the technology will be developed further, and likely will become economically feasible for widespread use.

      Please pay more attention to the intention behind people's language. You should know perfectly well what their use of "3-D clothing" means. It shows that they are designing the structure of the fabric instead of using layers of a single fabric type. Regular T-shirts can be sufficiently described as being "a human shaped roll of 2-D wool" or whatever. While you have found a technical error in their language usage, you would paradoxically have to be a moron to not understand their intention.

    • Here's my guess as to what "3d Textile Structures" means

      2d Textile Structures is in regards to the process of weaving fibers together that being the most common way to create a textile.

      I think the Special 3d way is by making actual fiber like cell structures on a microscopic level and binding those together. Think tempurpedic memory foam etc.

      That's just my guess can anyone please shed a little more light on this?

      Traditional fabrics are woven in 2 dimensions. Consider cloth a plane, a 2 dimensional entity. It is wrapped about a 3-D body to create a piece of clothing. Cloth is very 2-dimensional.

      Instead here the fabrics are being considered in three dimensions from square one - their manufacture is in three directions to provide sweat wicking and other interesting properties.

      • by ghjm ( 8918 )
        Weaving would be impossible in two dimensions. A loom has vertical threads all parallel to each other. The weave is created by passing horizontal threads alternately in front of and behind the vertical threads. In two dimensions, once you had the vertical threads set up, you would not be able to pass any horizontal threads through them because two objects can't occupy the same space at the same time. You need a third dimension for the weave to exist in.

        There's a big difference between "flat" and "2d."

  • When I go into a building with uncontrolled fire I have gear currently weighing between 60 and 80 pounds. This includes a pants and jacket made with a gnomex fabric, traditional helmet, heavy leather boots with steel under the foot, in the toes, and at the shins (which is nice when you bark your shin on a ladder). I'm wearing on my back an air bottle and SCOTT pack good for 30 minutes or so (a full hour if I'm acting as a member of a Rapid Intervention Team - RIT). My face is covered with mask that allows me to use that air, and I'm wearing a carbon fiber hood that encircles the mask and covers my head and neck. Long leather gloves cover my wrists to the inside of my jacket. I am "Fully Encapsulated".

    I am fairly safe from heat and smoke up to the point of a 'flashover' -- in which case I have between 4 and 16 seconds to be somewhere else before being incinerated. I am so well protected, that many of the guys refuse to wear the hood or else won't fold down the leather flaps on the helment to cover their ears further because their warning for when the heat is too intense is when their ears start to feel too hot even through the protection.

    In addition to all this, I am carrying one or more of the following: Radio, Light, Axe (or other similar tool), Water Can, Thermal Imaging Camera, escape rope, hose line.

    Exactly how is it that this fancy jacket or undershirt is going to help me? I'm hot, but not so much that I can't make it through the 20 minutes in there. When I come out, I am handed a 20oz bottle of water and expected to finish it on the spot while having my pulse and respiration checked before even considering going back in.

    This jacket would supposedly protect me from flashover -- several thousand degrees where anything that can combust, will.

    BULLSHIT.

    Even if the jacket worked, my face mask would melt to my face while the straps on my airpack along with the protective clothing I'm wearing would literally disintegrate.

    The way to be protected from a flashover is to jump out the nearest window or to use the axe you're carrying to make a hole in the exterior wall and dive through it. That's pretty much it. When it comes to flashover -- Don't be there. If you are there, get out. I've taken classes that involved practing the fine art of going out a second floor window head first onto a ladder and flipping over, or slamming an axe into a wall braced across the corner of a window, tieing off a big of rope to it and bailing out the window -- even if its just to hang 20 or 30 feet down from the room where the flashover is about to happen until someone gets around to moving a ladder to you.

    Don't believe this crap that a little water held in that jacket is going to help.

      Just wanted to say, your department really needs to get with the times and I would also recommend a department subscription to Fire Engineering magazine and a complete set of IFSTA and NFPA manuals.

      You should know that there are modern methods of combating flash over. The first is to ventilate the structure and the second is to use short burst of spray from a 60 degree fog nozzle which cools the unburned particles of combustion (aka smoke) just enough to eliminate flashing but not so much that the smoke banks downward. The latter is known as the 'Swiss' method because it was developed by Swiss engineers and firefighters.

      You should also know that leather boots are not recommended for structure firefighting by the NFPA. Your department should be wearing bunker boots, we wore Fire-Walker bunker boots made by Ranger Footwear, and Nomex pants jackets and hoods.
      I don't know of a fire department anywhere that still wears 'traditional' firefighting helmets with leather ear protectors, except yours, I guess. Most department have been wearing composite helmets with face shields and Nomex ear protectors.

      Everything I've described here is 'old' technology.

      Oh, and sticking a pick-headed ax in a wall, tying a rope to it and jumping out a window to escape a flash over? Sounds like something someone pulled out of their ass.

      By the way, over a 24 year period I was a Firefighter I, II, III, Firefighter/Paramedic, Fire Specialist, Fire Engineer and Engine Company Captain. I've been retired for 8 years.

        A) How much more do you think I can carry and still hope to pull someone else out? Water is HEAVY.

        B) What good is a cool suit if the mask I'm wearing melts off my face?

        • The exapnsion depends on the pressure and temperature (PV = nRT). At the higher temperatures in a fire the water might expand 20000 times.

          • Convection doesn't really create the kind of turbulance you'd see in a liquid, but unless someone screws up and just starts putting too much water on the smoke and destroys the thermal layering, it can be hundreds of degrees hotter at your head high than at your feet. The rule generally goes "if you can't see your feet, crawl". In a fire where the thermal layering isn't artificially destroyed or one that is being vented once attack starts, you can sometimes see clearly at foot level and not at all at kne
            • Thanks for the interesting post. I was referring to convection as a heat transfer mechanism to protective clothing, where it is fairly minor compared to the radiation. What you are referring to is actually 'stratification', where different temperature fluid separates out.
              • My terms may not agree with the once used as scientists study heat transfer. The primary sources of heat we face come from the following:

                - Superheated air & gasses from the source of the fire. The fire itself is (except on TV) usually in one place. We spend a lot of effort getting to the fire, crawling under hot gasses and smoke. We also spend a lot of effort doing searches in parts of the building not on fire but heavy with heat and smoke. I've been considering this convection.

    Ugh. I literally JUST got back in the door from a structure fire (sorry, no links to pictures yet, but they'll be up in the morning at www.kuhlhosefire.org). My bunker gear was sopping wet when I finished my second bottle, and we were just doing RIT/overhaul! (Uh, sorry, overhaul is what you do when the main fire is out and you find all the hot spots and burning debris and put it out so that you don't get called back three hours later once everyone is home in bed).

    There are a couple of major issues that this technology might address that would be helpful.
    1) At hazmat incidents, turnout gear is frequently inappropriate. The people doing the hot zone work are in "level 1" suits, which are fully encapsulated. However, level 1 suits are HOT, and level 1 techs are hard to come by. This might make it easier for level 1 techs to stay in the hot zone for longer periods of time or perform more evolutions.
    2) For my brother firefighter who pointed out that structural firefighting gear including nomex hoods provide inadequate protection for flashover (or getting steamed by the idiot outside who started squirting when we're inside), imagine having a level-1 type of setup for fighting fire. Your hands and head are no longer the most vulnerable because with this new technology your whole body is being cooled actively. I realize that level 1 is bulky and wouldn't be appropriate NOW, but if the technology is available someone will figure out a way...
    3) Barn fires in August just KILL crews. If you're standing outside in the sun for any length of time in turnout gear, you get completely baked. This might make it easier for us to endure fires in summer.
    4) Brush fires suck. SOG for departments that don't have nomex jumpers for fighting brush fires are to wear FF boots, turnout pants, and gloves. So you're slogging around through chest-high red brush getting cut to hell, a mile off the road, getting your ass kicked in your heavy gear, taking a shovel, axe, or if you're a rookie an Indian Can strapped to your back. Again, it doesn't take long to get overheated. Maybe not any longer.

    I hope that the technology performs. I'm whipped.
