I've received a few questions lately, so I thought it would be time for a repost.
Not sure why the links are acting up.

My fire suppression system was approved by BS1.... But you probably don't remember, since it was a while back

Well done, you have purchased the absolute best fire protection system made.
Here's a brief rundown
Halon..puts out the fire but does not offer a "blanket" which, if the fuel is on metal can lead to reignition. It also occludes oxygen but for the most part that's not an issue for us since we aren't in a closet
Co2..basically same as above
Dry Chem..extinguished fire and leaves a blanket to prevent reignition, but it is very acidic and will destroy any electrical connection and damage electronics
AFF..Aqueous Film Forming Foam..extinguishes fire and provides a blanket to prevent reignition, the main component is water which is easily washed off and non corrosive. You can't use it on higher voltage electrical fires so it won't work on a Tesla but it's perfect for us. ARAFFF is used on alcohol fuels.
