Product overview
CHEMGUARD CLASS A PLUS is a low-concentration firefighting foam for ordinary combustible fuels. It improves wetting and can be used with documented handline, CAFS and rotary-wing delivery arrangements. Finished foam expansion depends on the selected discharge equipment and operating method. The concentrate should be stored separately from any solution prepared for immediate use; long-term premix storage is not recommended. Select the dilution for the delivery device rather than applying one rate to all uses. Confirm the current safety data, equipment compatibility and container requirements when specifying the supply.

Key features
- Product: CLASS A PLUS Class A foam concentrate
- Overall proportioning range: 0.1–1.0%, application-dependent
- CAFS dilution: 0.1–0.3%
Applications
Class A hazards involving wood, paper, coal and rubber with an appropriate foam delivery system. Aerial use and any emergency application beyond the core Class A scope require the applicable equipment and operating approvals.
Selection and project integration
Provide UDCT with the fuel or test application, required capacity, available water pressure and flow, selected concentrate and compatible equipment. Confirm the exact part numbers, coupling threads, storage conditions and current manufacturer instructions. For foam systems, use the fuel-specific application criteria and approved proportioning/discharge assembly; commissioning must verify the actual hydraulic and proportioning performance.
