What is the guideline regarding working at heights?

• A. You can work at heights alone if you are experienced.
• B. No working at heights without supervision.
• C. Always wear safety goggles; otherwise allowed.
• D. Only during daylight hours.

Answer: (B)

Working at heights carries a real risk of serious injury from falls, so the guideline emphasizes that you should not perform such work without supervision. A competent supervisor ensures the job is properly planned and controlled: a risk assessment is considered, fall protection is ready and used correctly, ladders or scaffolds are set up safely, tools are secured, and a rescue plan is in place if something goes wrong. This oversight helps catch mistakes, confirms that safety rules are followed, and can intervene before an unsafe situation develops. Even if someone is experienced, conditions can change and equipment can fail, so supervision remains essential. The other options don’t address the core safety need: wearing goggles protects eyes but does not prevent a fall, and working only during daylight hours has no bearing on the need for supervision when heights are involved.
