Lithium Safety Testing - 8th December

[teamstorm]

You can see why an EO might be concerned - and it takes more than a fan and a hose to shift that volume of air !

But I think we'll soon get agreement there isn't a safety issue in play

4min 50sec into the fight :shock:
Sorry was it only me who saw the flames?

Something like that with ducting similar to that flexible tunnel stuff you played with as a kid would clear that space in no time

And what is the problem with fire?

[blazerbotics]

Fire are a concern anywhere, i'm more worried about fire in the pits than in the arena though, smoke is an issue when in the arena. The fan you pointed out Gary, doesn't take ducting, if you look they do the smaller ones that do, for that we're looking £500 for a setup and it would take about 8minutes to empty our arena.

The issues aren't as much with the batteries themselves, but more the users attitude towards them. This is for me the big issue to get around.

As someone who has no experience currently with these batteries, I'm am waiting in anticipation the tests/talk about them, even though tests are being carried out by certain experienced roboteers it would be good to see a video/discussion directly from experts and willing to show the worst case scenario, good to see someone grab the bulls by the horns (as it were) it will b nothing but educational to all, well done robochallenge!!
But in the videos I have seen on youtube I worry about the head scratching it all cause for eo's, plus the extra cost in dealing with a incident quickly, I have seen first hand in keeping audience occupied in a battle changeover let alone waiting to clear a arena of smoke, out of interest with no experience myself, are the fumes pretty nasty in smell??? As a audiance member it could be quite good viewing tbh, but things are bad enough in these economic times and from a eo point of view how does allowing these batteries benefit them??should the worst happen,

Btw I'm happy to here opinions or arguements, just trying to think outside the box that's all

Fire are a concern anywhere,

A starting fire is something you have to deal with.
In case of a LiPo fire in the arena, keep the burning machine in a cloud of CO2, to avoid ignition of more stuff. Using anything else would case damage to everything, delaying the show a lot.
And except some exotic foams or powders, quelshing a Lithium fire is next to hopeless. On the other hand, the amounts of lithium, even for heavies, are not that impressive.

I'm more worried about fire in the pits than in the arena though, smoke is an issue when in the arena.

The smoke is a problem everywere.

The fan you pointed out Gary, doesn't take ducting, if you look they do the smaller ones that do, for that we're looking £500 for a setup and it would take about 8minutes to empty our arena.

Well spend £500 then.

The issues aren't as much with the batteries themselves, but more the users attitude towards them. This is for me the big issue to get around.

That was an issue with any kind of battery. Even seen an exploded lead-acid? I did. Not funny.
I still see the burning NiCd pack at Maidstone a lot of years back.. Who was running around with it, the battery dangeling on a half molten wire? To dunk it in a bucket of water.

Oh well, more rules please.

Is the risk of fire not greatly increased by doing what they did in that video - continuing to fight? Running a badly damaged battery for that long after the smoke starts seems crazy. At an event here, at the first sign of smoke make it a thing that everyone stops dead and it is dealt with immediately. I don't know how LiPos ignite but in a situation like the one in the video, perhaps the fire could have been avoided.

Unless already planned, maybe that's a test to do, Grant and co., running a LiPo after it has been damaged and what happens when you do?

[mattsdragons]

I would agree with ellis there, would be interesting to see what can happen if a damaged lipo is kept running incase with all the co2 exausts etc it wasnt noticed till too late

[typhoon_driver]

I await the results of the tests and the subsequent ruling with much interest
