General-duty citation text

Section 5(a)(1) of the Occupational Safety and Health Act of 1970:  The
employer did not
furnish employment and a place of employment which were free from
recognized hazards
that were causing or likely to cause death or serious physical harm to
employees in that
employees were exposed to a potential struck-by hazards associated with
the structural failure
of a crane's boom:
(a)Derr & Gruenewald Construction Co. & 12401 E. 17th Ave, Denver, CO
80045: On or before September 19, 2006, the employer's designated person
responsible for the crew involved in the off-loading of steel beams from a
flatbed trailer, did not ensure that the information provided to the crane
operator was accurate involving the actual weight of the steel beams. The
foreman indicated to the crane operator that each beam weighed 1000 lbs, in
which the beams actually weighed 2000 lbs per beam. This condition resulted
in a load that exceeded the Manitowoc 4100 Series 1 with a No. 23 boom and
No.124 jib lifting capacity and the eventual structural failure of the
boom.
Among other methods, one feasible and acceptable abatement method to
correct this hazard
is to follow ASME B30.5-2000, The American Society of Mechanical
Engineers-An
American National Standard-Standard for Mobile and Locomotive
Cranes-requirements
associated with Section 5-3.2 Operating Practices:
5-3.2.1.1 Size of the Load
(c)When loads that are not accurately known are to be lifted, the
designated
person responsible for the job shall ascertain that the weight of the load
does
not exceed the crane ratings at the maximum radius at which the load is
handled, as per ASME B30.5-2000, The American Society of Mechanical
Engineers- An American National Standard- Safety Standard for Mobile and
Locomotive Cranes.
