Cernol Fire Training Foam (RLF 4) in Namibia

Muscle memory on real hardware: pickup, induction rate, branch handling and blanket application all behave in a drill exactly as they would at an incident, because RLF 4 reproduces realistic foam expansion and flow through the appliance’s own proportioning equipment. Crews that drill quarterly on RLF 4 arrive at a real fuel fire with practised evolutions instead of theory — and the drill log to prove it to auditors and insurers.

Cost and compliance: certified operational concentrate is expensive, its consumption must be replaced to hold mandated stock levels, and modern environmental scrutiny of fluorinated firefighting foams makes discharging them for practice increasingly indefensible. RLF 4 exists precisely to absorb the drill calendar — realistic behaviour, training-foam price, cleaner environmental profile — while the certified stock stays sealed.

Like any concentrate: original sealed drums, shaded and cool, batch numbers visible, first-in-first-out. Keep it clearly labelled and physically separated from any certified operational stock so a night-shift drill can never tap the wrong drum. Log drill consumption and reorder against the training calendar — Cernol supplies from Windhoek, so replenishment is days away, not an ocean freight cycle.

The operational concentrate range (AFFF, protein and fluoroprotein grades) has been discontinued; RLF 4 training foam is the range’s continuing product. The rest of the fire-service order stands: Ardrox NDT chemistry for equipment certification, and the appliance-bay and station chemistry.
