Question 800 Deck Safety

The correct answer is A) 10 times greater. The amount of low-expansion mechanical foam produced is typically about 10 times greater than the amount of concentrated foam liquid used. This is because the foam concentrate is mixed with air and water to produce the larger volume of low-expansion foam. The expansion ratio, which is the volume of foam produced compared to the volume of concentrate, is generally around 10:1 for low-expansion mechanical foam. The other answer choices are incorrect because they do not accurately reflect the typical expansion ratio for low-expansion mechanical foam. The expansion ratio is not 97 times, 2 times, or 94 times greater than the amount of concentrate used.
