all over Drywall ihouses are so failed country style - Bricks and Concrete FTW ;-)

They're $400 a pop. Petzl aren't a charity.

Far cheaper for them to use webbing and a tool to sling themselves out. Someone has a tool and both should have some length of webbing ("Different strokes"), you may not be able to rappel all cool like but your ass won't cooked

@@Goldenfightinglink that seems far more inconvenient... especially as this is only done in a life threatening situation

@@bensblues I know plenty of firemen that choose and use webbing way more often

You can't insulate with a thin coating, because insulation value is proportional to the thickness of the material and a coating is of thickness 0 for the purpose at hand. You could possibly use a reflective material to reflect as much infrared as possible, for example by painting the rope with titanium oxide, but this would do nothing against an open flame or simply hot air / convection. There's flame retardants, but those only protect against the material self-sustaining a fire, and if you heat a rope enough for it to start burning itself, it's already dropping you to the ground anyway. The only thing that could possibly work would be to have a material coating that changes phase. For example, aviation black boxes have some water in them, while it's boiling up it keeps the temperature of the box at 100⁰C. There's several problems though. First, it's not clear what material could have the desirable property without imparting negative ones. Second, the amount of protection would be proportional to the mass of that material, and thus unlikely to amount to much. Third, a rope can break at any point, and when heat affects just 1% of the length, the remaining 99% of the coating does absolutely nothing. The only solution is to use rope materials that are certified to resist to heat in the first place. There's many technical polymers such as polyimides that can withstand 100s of degrees, though they might not all be appropriate for making rope. But I'm sure firefighters use materials that are certified for some amount of heat resistance. edit: the Petzl rope is made from aramid. Melting point is >500⁰C

Sure, if you've got $460 to burn

The rope has a higher heat resistance temperature. It only has to withstand slightly more heat than a fully suited firefighter can handle and last long enough for the firefighter to get out and down.

+Jeffrey Cook you might not, but who cares if it saved your life

With a broom and dustpan. You lived. To save life ALL equipment is expendable, buildings are expendable, apparatus is expendable. In other news, jet fighters have ejection seats because riding it in accomplishes less than nothing.

para salir con una victima en brazos ya necesita el ID L o el ID S, que son para rescate, esos cuestan doscientos cuarenta euros, son mucho mejores y eficientes que el que se esta hablando aqui, pero entendamos...., para usar un aparato como estos hay que tener practica y experiencia, y sobre todo formacion, los anclajes son muy importantes, arnes y anclaje en punto firme de sujecion , luego el ID S, es una maravilla de descensor para utilizarlo con una gran confianza y tranquilidad, si,

The Technora sheath has a very high melting temperature. It will eventually burn through but hopefully you've escaped by then

The biggest problem about rope access or professional applications like this is that you cant discuss about it without layman talking bullshit, thinking they are the professionals.

It is better to remain silent and be thought a fool, than to speak and remove all doubt. It is unfortunate that the internet provides anonymity to oxygen pirates.

Shawn Mccoy that rope can take 1000 kg or an elephant

And its kevlar infused so it won’t melt.

O shut the fuck up

@@jakethegreat4466 Come on man, he is clearly joking. Relax.

Daniel L hes only mad cause it happened to him dude slipped out the window

@@aninjawaffle98 I think so too! lmao

It's based of the same mechanism as a grigri. If you look on petzls webpage you will see that the majority of their devices look like big or small funny shaped grigris. The I'D, Rig , grillon, grigri and exo all work and are designed on the same premise. It's not a bad thing.

You have no idea what you are talking about. Not everyone are like you. Some are, but these are professionals.

Rope? Who gives a fuck about 50 feet of rope?

cant get your life back either
