Robert,
Any motorsport event in SA, which is CAMS affiliated, (eg operates under CAMS licenses), requires Flaggys, Ambos and Firerys.. the Flaggys are SAFMA, firerys are WFW, and Ambos usually SAAS.. / Motorsport Medical services.
Don't think u can become the" South East Fire Marshal " as i doubt an official title exists... an any events which operate under CAMS would require the teams I listed above...
