Safety Trained Supervisor in Construction (STSC) Practice Exam

What is the maximum distance a worker should have to travel to access a ladder for entering and leaving an excavation?

1. 10 feet

2. 25 feet

3. 50 feet

4. 100 feet

The correct answer is: 25 feet

The maximum distance a worker should have to travel to access a ladder for entering and leaving an excavation is set at 25 feet to ensure safety and efficiency. This guideline is established to minimize the risk of falls and accidents—critical concerns when working around excavations, where the potential for serious injury is high. Having a ladder within 25 feet means that workers can quickly and easily access a point of safety, mitigating extended exposure to hazards such as trench collapses and falls. It's essential for employers to comply with this standard, as it reflects an understanding of the hazards present in excavation work and the necessity of providing safe access and egress. If the distance were longer, such as 50 feet or 100 feet, it could lead to increased fatigue and a higher likelihood of accidents as workers may attempt unsafe shortcuts or delay their exit in an emergency situation. The standard is designed not only to promote safety but also to encourage proper training and awareness among workers regarding the importance of maintaining safe access to ladders in excavation sites.
