Which of the following is a common cause of tripping hazards in buildings?

Uneven flooring or loose carpets are significant tripping hazards in buildings due to their propensity to create abrupt changes in walking surfaces. These irregularities can cause individuals to stumble or trip, resulting in falls that may lead to injuries. Proper maintenance and inspection of flooring surfaces, as well as securing carpets, are crucial in preventing these hazards.

In contrast, freshly painted walls do not impact the floor surface and therefore do not contribute to tripping. Properly secured handrails are actually essential for safety and help prevent falls, thus reducing the risk of tripping hazards. Installed fire alarms pertain to safety in emergencies and do not influence tripping risks in any way.
