What is the maximum allowable distance of a worker from the support face when plastering and lathing?

In the context of plastering and lathing, the maximum allowable distance of a worker from the support face is determined by safety regulations that aim to provide a balance between accessibility and stability while performing the task. The option indicating 18 inches (46 cm) as the maximum distance adheres to established safety standards, ensuring that workers can reach the end of the lathing or plastering support while maintaining stability and reducing the risk of falls or accidents.

This distance is set to ensure that workers can effectively and safely apply materials without compromising their balance or ability to maneuver. Staying within this range allows for adequate support and control, which is critical in achieving the desired finish and quality of work while minimizing physical strain on the worker.

Other distances mentioned, such as 10 inches, 12 inches, or 24 inches, either restrict movement too much or increase the risk associated with working at further distances from the support. Thus, the choice of 18 inches represents a well-considered standard in construction safety practices related to plastering and lathing operations.
