Asbestos Contractor/Supervisor Practice Exam

When considering the requirements for free-standing mobile scaffolding, the height of the scaffolding plays a critical role in determining the necessary features for safety and compliance. A scaffold that is 16 feet high must adhere to specific guidelines to ensure stability and safety for workers. Lockable wheels are essential because they prevent movement while the scaffolding is in use, minimizing the risk of accidents. A minimum width of 4 feet is also critical for maintaining stability and preventing tipping; it ensures that the scaffolding structure is wide enough to support its height safely. Furthermore, regular inspections by a competent person are mandatory to identify and mitigate any potential hazards before the scaffolding is used. In this context, the minimum height of 10 feet is not a requirement for a scaffold that is 16 feet high. While it is true that scaffolding has structural safety requirements, the specification itself is focused on those exceeding practical heights typically found in construction. Therefore, stating a minimum height serves as a guiding principle but does not apply as a strict requirement for scaffolding that already exceeds that dimension. Hence, while the scaffolding in question is 16 feet tall, the stipulation of a minimum height of 10 feet does not add any additional safety regulation needs in this scenario.
