Final answer:
The control line system for overhand bricklaying operations should connect to walls or guardrails on all sides and have a minimum breaking strength of 1500 lbs.
Step-by-step explanation:
When marking out the controlled access zone for overhand bricklaying operations, your control line system (whenever possible) should connect to either walls or guardrails on all sides.
The control line system will need to have a minimum breaking strength of 1500 lbs.
This ensures that the system is strong enough to support the weight of the workers and materials and maintain a safe work environment.
