Which foam expansion category has a range of 200-1000?

• A. Low expansion
• B. Medium expansion
• C. High expansion
• D. Ultra expansion

Answer: (C)

Foam expansion is about how much the foam solution grows into foam—the expansion ratio. It tells you how many times the original liquid volume becomes foam, which in turn affects how quickly and how much foam can fill a space. A range around 200 to 1000 times indicates a foam that’s fairly light and highly expansive, designed to blanket large enclosed or complex areas quickly and help displace or smother the fire. That’s the hallmark of high expansion foam. Lower expansion foams are denser and don’t fill as much volume, while ultra expansion would push beyond 1000 and produce even lighter foam for even larger, more open spaces.
