|MEMORANDUM FOR:||AREA DIRECTORS|
|FROM:||JOHN B. MILES, JR|
|SUBJECT:||Christmas Treeing, Steel Erection|
Enclosed is documentation from the manuals of the Construction Industry Manufacturers Association, FMC Corporation, Construction Safety Association of Ontario and the Structural Manual V, Volume I for Ironworkers. This information was forwarded to this office by the Area Director of the Harrisburg, Pennsylvania office and is currently being used in Region III to support 5(a)(1) citations for the practice of hoisting multiple loads (Christmas Treeing) by cranes.
Effective immediately, Supervisors and CSHOs are advised that the practice of lifting multiple loads with a crane are citable under Section 5(a)(1) of the Act and that the attached information can be used to show that the hazard is recognized in the industry.
Particular attention, however, needs to be taken to thoroughly document the hazards to employees who man tag lines, work under the hoisted loads, methods of rigging the load, weather conditions, etc. so as to support the issuance of a 5(a)(1) citation. Photographs taken of employees under the suspended loads will also help in substantiating violations.
For your future reference, Region III considers Tom Doherty of the Harrisburg Area Office to be an expert in the hazards of multiple load hoisting. Tom has 21 years experience as a crane operator in the construction industry.
