Question

Quizplus · Accepted Answer

Foam produced by compressed air foam systems (CAFS) has a unique quality of adhering well to vertical surfaces, which is a significant advantage in firefighting operations, especially when trying to coat and protect structures or contain hazardous material spills. This characteristic is due to the foam's consistency and the air bubbles within it, which help it cling to surfaces rather than immediately running off.
