A wall hole is specified to be between what height range?

• A. 1 - 30 inches tall
• B. Greater than 30 inches tall
• C. Less than 1 inch tall
• D. 10 inches tall

Answer: (A)

The concept here is how OSHA defines an opening in a wall by how high it sits above the floor, which determines when guarding or protection is required. A wall hole that is between 1 inch and 30 inches tall sits in a range where it is treated as an opening that can pose a fall or injury risk and thus requires appropriate protection or guarding. Holes smaller than 1 inch are usually not considered openings needing protection, while holes taller than 30 inches fall into another category with different guarding rules. So, the height range of 1–30 inches tall is the standard range used for this type of wall opening.
