Published by SALUS

In Massachusetts, when using control lines to demarcate a Controlled Decking Zone (CDZ), the control line must be erected not less than six (6) feet (1.8 m) nor more than ninety (90) feet (27.4 m) from the leading edge 1, 7. These control lines should extend along the entire length of the unprotected or leading edge and be approximately parallel to it 1, 7.

The control lines must also meet specific criteria [1]:

  • They must be made of ropes, wires, tapes, or equivalent materials, supported by stanchions or other suitable anchorages 1, 7, 8.
  • Each line must have a minimum breaking strength of 200 pounds (90.8 kg) 7, 8.
  • The lines must be rigged so that the lowest point (including any sag) is between 39 inches (1.0 m) and 45 inches (1.3 m) from the walking/working surface 7, 8.

Remember that a painted line on the surface or a sign is not an acceptable substitute for control lines [1].
