| MEMORANDUM FOR: |
AREA DIRECTORS |
| |
| FROM: |
JOHN B. MILES, JR |
| |
Regional Administrator |
| |
| 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.
