The two types of protection for openings in walls, floors, or the ground are...

• A. Guards
• B. Guards and covers
• C. Covers only
• D. Lids and rails

Answer: (B)

Openings in walls, floors, or the ground create fall and hazard risks, so protection comes in two essential forms: a guard and a cover. A guard is a physical barrier that surrounds or encloses the opening to block access and prevent someone from stepping into the opening. A cover sits over the opening to stop people or objects from falling through and is typically rated to carry the expected load and securely fastened so it won’t shift or tilt. Together, guards and covers provide complete protection: the guard handles preventing access, while the cover handles preventing entry or fall through the opening itself. Terms like lids and rails aren’t the standard way these protections are described, and relying on only one type (either guards or covers) would leave gaps in safety.
