I should have worded my response differently as in a bare minimum recommendation for HPDE usage.
As for actual motorsports usage the Lifeline 201 AFFF is not certified, which is also what makes it affordable, but it's also not due to it being AFFF (Aqueous Film Forming Foam). If a person is going to by a certified hand held then
https://competitionmotorsport.com/li...d-extinguisher would be a way to go as that is ABC rated, none directional usage, bottle is designed to be in a abusive motorsports environment and is a clean agent as well. Also a person needs to check the GCR of the sanctioning body they run with to verify if a handheld is legal vs using a fixed system in the car and what size they are required to have in a hand held or fixed system.
I interpreted the question on the suggested item, as with most HPDE drivers I am around, wanting to be safe but not having much for the budget.
