How can you identify a platform edge door gap hazard?

• A. Recognize warning signs and maintain safe distance; ensure platform alignment.
• B. Step over the gap and continue boarding.
• C. Assume there is no hazard on modern platforms.
• D. Stand directly above the gap to observe.

Answer: (A)

Recognizing when you’re near a platform edge gap comes down to spotting the safety cues and keeping well back from the edge. Look for warning indicators such as yellow edge markings, gap markings, and other caution signs, and listen for announcements. These cues tell you where the danger lies and remind you to stay behind the safe line and away from the gap. Keeping a safe distance also means you’re not trying to step into or over the gap; you wait until the train doors are fully opened and the area is safe before approaching. It’s also important to choose a boarding position where the door opening aligns with a solid, level surface, so you’re not stepping into the void.

Stepping over the gap is unsafe because it ignores the warning cues and the risk of slipping or the door closing unexpectedly. Assuming there is no hazard on modern platforms is incorrect, since gaps and misalignments can vary and pose real risks. Standing directly above the gap places your body over the edge and increases the chance of losing balance or being drawn into the gap.
