Option 2. Warning lines
Option 3. Safety nets
Option 4. Control lines

Answer 1

Guardrails must be flagged at 6' intervals with high visibility material and erected along each side of a roof work area to prevent falls from heights and protect workers. Warning lines, safety nets, and control lines serve different purposes and do not provide the same level of fall protection as guardrails.

Step-by-step explanation:

Guardrails must be flagged at 6' intervals with high visibility material and erected along each side of a roof work area. Guardrails provide a physical barrier to prevent falls from heights and protect workers. They are often made of metal or strong materials to ensure stability and durability.

Warning lines are used to mark off designated work areas on a roof, but they do not provide the same level of fall protection as guardrails. Safety nets are another type of fall protection system that can be used to catch workers or objects that may fall from heights. Control lines, on the other hand, are typically used to control access to a work area, but they do not offer fall protection.
