How far through the exit use zone does the Slide Clearance Zone continue?

The Slide Clearance Zone starts at the edge of the exit opening and continues indefinitely, until the person using the slide reaches the ground or other safe location. Option A is incorrect because the use zone does not end until the user reaches the ground. Option C and D are incorrect because they provide specific measurements which may not apply in all situations, whereas the Slide Clearance Zone does not have a set distance and depends on the height of the slide and height of the user. Therefore, the correct answer is B.
