2Regulatory OverviewOn July 9, 2004, the Federal Advisory Committee on cranes and derricks (C-DAC) reached a consensus for a new crane and derricks standard.In May 2008, as part of its semiannual regulatory agenda, OSHA mentioned plans to publish a notice of proposed rulemaking on cranes and derricks in the August 2008 Federal Register.

10Types of Cranes Involved in Fatalities Mobile cranesTower cranesFloating or barge cranesOverhead cranes
11Types of Cranes Involved: Mobile Cranes71% of all crane-related incidents involved mobile cranesMobile cranes were involved in:80 of 95 (84%) of overhead power line incidents37 of 59 (63%) of crane collapses35 of 59 (60%) of struck by boom/jib incidents
12Types of Cranes Involved: Tower CranesTower cranes wereinvolved in:16 of 306 (5%) of all crane related incidents5 of 24 (21%) of struck by crane load incidents5 of 59 (8%) of struck by boom/jib deaths
13Other/unspecified cranes Types of Cranes Involved:Other/unspecified cranesOther/unspecified cranes were involved in 24% of all crane related incidents, including:13 floating or barge crane incidents12 overhead crane incidents
14Main Causes of Worker Deaths, by Frequency Electrocutions – from overhead power linesCrane collapseStruck by falling boom/jibStruck by crane load

20Recommendations Crane operators should be certified. Presently only 15 states and a few cities (including New York City and Chicago) require certification.Crane riggers and signalpersons should be certified.Crane inspectors should be certified.OSHA only requires that they be competent persons
21Recommendations (cont.) Cranes should be inspected after assembly or modification.Only trained workers under the supervision of a qualified person and competent person should assemble or disassemble cranes.Crane loads should not be allowed to pass over street traffic.
22Recommendations (cont.) OSHA should conduct more thorough investigations of crane-related fatalities and capture more complete data in its reporting system.OSHA should immediately take action on the proposed consensus crane and derrick standard for construction and include recommendations from this report.
