Question 806 Deck Safety

You are correct, the answer is A) be drier. High-expansion foam has a lower density and more air content compared to low-expansion foam. This makes high-expansion foam drier and less viscous, allowing it to flow more easily and not cling to vertical surfaces as well as low-expansion foam. In contrast, low-expansion foam is more dense and has a higher water content, making it heavier and more heat resistant. The other options B) be more heat resistant and C) be heavier are characteristics of low-expansion foam, not high-expansion foam.
