Which statement is true about a balanced pressure foam system’s discharge outlets?

• A. They require a single discharge outlet
• B. They allow various percentages of foam solution to be discharged from multiple discharge outlets
• C. They prevent any foam discharge from direct injection
• D. They disallow simultaneous discharge of water and foam

Answer: (B)

Balanced pressure foam systems are built to mix foam concentrate with water at a precise proportion and to deliver that foam solution through multiple discharge outlets. This design lets you control and vary how much foam solution is discharged from each outlet, giving flexible, wide-area coverage as needed for different incident scenarios. The key point is that the system maintains balanced pressures so several outlets can operate together or independently while maintaining the correct foam-to-water ratio. The other statements don’t fit because one outlet would limit coverage, the system isn’t defined by prohibiting direct injection, and discharging water and foam together is exactly how the foam solution is produced and released.
