Which of the following is a requirement for compressed air foam system regulators?

Explanation:
Regulators in a compressed air foam system must be listed for use because listing verifies that the component has been evaluated and approved by a recognized testing organization for CAFS applications. This confirms the regulator is compatible with the foam concentrate, materials, and operating pressures, and that it will perform safely in the demanding firefighting environment. Features like automatic shutoff or battery power may appear in some designs, but the essential requirement is that the regulator is listed for use. Using a listed regulator helps ensure proper foam proportioning, prevents leaks, and reduces the risk of regulator failure during operation.
