Training foam for fire brigades & airports

Crew competence needs regular foam drills, but certified operational concentrate is expensive and environmentally scrutinised. RLF 4 reproduces realistic foam behaviour through your real equipment — induction, expansion, blanket forming — at training-foam cost and with a cleaner environmental profile. Brigades and airport fire services drill quarterly on RLF 4 and keep their certified operational concentrate sealed for real incidents, which also preserves its shelf life.

No — the operational foam concentrate range (AFFF, protein and fluoroprotein grades) has been discontinued. Cernol continues to supply RLF 4 training foam, and the rest of the fire-service list: Ardrox NDT chemistry for equipment certification, and the appliance-bay and station chemistry brigades order alongside it. If you need help sourcing certified operational concentrate, talk to our sales team and we will point you in the right direction.

That is its purpose: RLF 4 is designed to run through standard induction and proportioning equipment so a drill exercises exactly the hardware and crew actions a real incident would — pickup, induction rate, branch handling, blanket application. Check your inductor’s calibration before the drill, run the training evolution, and rinse the system with fresh water afterwards so residue never blocks a pickup tube.

Like any foam concentrate: in original sealed drums, out of the sun, within the label temperature range — Namibian heat is the main enemy of stored concentrate. Keep batch numbers visible, rotate first-in-first-out, and log drill consumption so reordering happens before the training calendar catches you empty. Cernol supplies from Windhoek, so replacement stock is days away, not an ocean freight cycle.
