Which items are listed as types of physical hazards?

• A. Surface hazards, unstable debris, overhead obstructions, confined space, below grade spaces, heights, vibrations, damaged utilities
• B. Electrical hazards and chemical spills
• C. Thermal hazards and radiation
• D. Psychological hazards only

Answer: (A)

Physical hazards are environmental factors that can cause harm through energy transfer—things you can be struck by, caught on, or exposed to in a way that could injure you. The chosen items cover a wide range of such hazards: surface hazards that can cause trips or slips, unstable debris that could shift or collapse, overhead obstructions that might strike, confined spaces and below‑grade spaces with limited entry/exit or dangerous atmospheres, heights that raise the risk of falls, vibrations that can affect hands and feet or damage equipment, and damaged utilities that can lead to shocks, leaks, or fires. This breadth makes it the best answer because it names several distinct physical-hazard types you need to recognize and control in real settings. Other options don’t capture that breadth. For instance, listing electrical hazards and chemical spills mixes a physical hazard with a chemical hazard, and isn’t as comprehensive about the range of physical hazards. Thermal hazards and radiation are physical hazards but only two examples, while psychological hazards are not physical hazards at all.
