• Equip single-point or two-point adjustable suspension scaffolds that use horizontal lifelines or structural members of the scaffold for fall protection with both of the following:
– Additional independent support lines that are equal in number and equivalent in strength to the suspension ropes;
– Automatic locking devices capable of stopping the scaffold from falling if one or both of the suspension ropes fail.
• Make sure horizontal lifelines are secured to either:
– Two or more structural members of the scaffold;
– Looped around both the suspension ropes and independent support lines above the hoist and brake attached to the end of the scaffold.
• Make sure independent support lines and suspension ropes are not:
– Attached to each other or the same point on the scaffold;
– Attached to or use the same point of anchorage.
• Make sure independent support lines and suspension ropes are not attached to either:
– A personal fall arrest system;
– The same point on the scaffold as a personal fall arrest system.
