What fire-extinguishing equipment must a heavy vehicle carry under the CEMAC Highway Code, and what does the international ADR standard add for a dangerous-goods load?

1. The code requires at least one extinguisher able to tackle a fire starting on the vehicle or its load; ADR practice adds a small cab extinguisher plus a larger certified unit for the load, each within its inspection date
2. The code requires nothing, and ADR practice is to carry a bucket of sand and a garden hose
3. A single 1 kg aerosol can in the glovebox satisfies both the code and ADR practice
4. No extinguisher is needed if the tank is fitted with an automatic foam suppression system
