According to Cal/OSHA, what is the minimum height for scaffolds to require guardrails?

• A. 5-½'
• B. 6-½'
• C. 7-½'
• D. 8-½'

Answer: (C)

The minimum height for scaffolds to require guardrails is established by Cal/OSHA regulations, which specify that guardrails are necessary when the scaffold is more than 7 feet in height. This regulation is in place to ensure the safety of workers by providing a protective barrier against falls, which are a significant risk when working at elevated heights.

At this height, the risk of injury from falls increases, and the presence of guardrails helps mitigate that risk, creating a safer working environment. The requirement for guardrails at this specific height aligns with the broader safety measures aimed at protecting workers and reducing the likelihood of accidents on construction sites.

In the context of the other options, heights below 7 feet do not trigger the requirement for guardrails according to Cal/OSHA standards, leaving the choice of 7-½' as the correct threshold.
