Which of the following is a common fall hazard in construction?

In the context of construction safety, fall hazards are critical concerns that can lead to serious injuries or fatalities. Lack of guardrails is a significant fall hazard because guardrails provide essential protection at edges of elevated surfaces where workers may be at risk of falling. Unstable working surfaces also pose a danger; when surfaces are not secure, they can cause slips, trips, or falls. Improper ladder use is another common fall hazard as it can lead to loss of balance or tipping, especially if ladders are not positioned or used correctly.

Since each of these options outlines a specific condition that can contribute to falls on a construction site, recognizing that all of these factors combined represent common fall hazards is key to understanding the comprehensive nature of fall risks in construction environments. Therefore, acknowledging that all listed hazards are applicable illustrates the importance of addressing multiple aspects of fall prevention in construction safety protocols.
