What is the significance of a 'two-person rule' or buddy system around high-risk tasks?

• A. It reduces the number of workers required.
• B. It extends shift length.
• C. It slows down operations.
• D. It ensures mutual assistance, improves hazard awareness, and helps in emergencies.

Answer: (D)

The main idea here is safety through mutual support and awareness. A two-person rule around high-risk tasks ensures there is always a partner who can monitor the work, notice hazards, and act quickly if something goes wrong. If a worker becomes overwhelmed, injured, or encounters a dangerous situation, the buddy can immediately intervene, provide assistance, and summon help. This setup also keeps hazard awareness high—each person looks out for the other, checks controls and procedures, and helps ensure proper isolation, PPE, and permit compliance. In an emergency, having a partner means help is already on site, so response is faster and rescue actions can begin without delay. So, the value of the buddy system is mutual assistance, better hazard awareness, and quicker emergency response. It doesn’t aim to reduce staff numbers, extend shifts, or slow down operations; those are not its safety-focused purpose.
