Which of the following represents a safety requirement for railings at construction sites?

For railings at construction sites, the requirement to be at least 1.0 meter tall is a crucial safety measure. This height is intended to provide effective protection against falls, which are a significant risk in construction environments, particularly on elevated surfaces such as scaffolding, roofs, or platforms. A railing that is at least 1.0 meter tall creates a barrier that minimizes the likelihood of workers falling to lower levels, thus enhancing overall safety on the job site.

In addition, standards from safety organizations, such as OSHA (Occupational Safety and Health Administration) in the United States, often stipulate this height as a minimum requirement to ensure adequate worker protection. Railings that do not meet this height may be insufficient to prevent falls or may not comply with local or national safety guidelines, leading to potential hazards for workers in construction settings.
