MEMORANDUM FOR: Vernon A. Strahm Regional Administrator
Subject: Citation under 1926.251(c)(3) of R.C. Williams Trucking Company

This is in response to your memorandum of August 2, 1976, same subject, regarding any comments and/or suggestions we deem appropriate on this citation.

The only comments we have to offer is 29 CFR 1926.251(c)(3), Rigging Equipment for Material Handling, Wire Rope, states that: "Wire rope shall not be secured by knots, except on haul back lines on scrapers." In addition, if this wire rope were used as a bull wire, then 29 CFR 1926.251(c)(4)(iii) requires that eyes in bull wires shall not be formed by knots or wire rope clips. The above standards recognize the hazard of tying knots in wire ropes used for hoisting, lowering, or pulling loads.
