Top 10 Crane & Rigging Losses Recognizing & Avoiding The Risks Presented by NBIS Insurance & Risk Management Team: Michelle Lorenz – Manager, Litigation & Claims Cliff Shepherd – Supervisor, Claims Billy Smith – EVP, Risk Management Acknowledgement to Jim Wiethorn, PE of HAAG Engineering for the Accident Scene Photos & Re-enactments
OSHA’s Crane & Rigging Fatalities Source: Crane Related Fatalities in the Construction Industry, ASCE’s Journal of Construction Engineering & Management (September 2006) • Not surprisingly, in 2001, OSHA determined that the construction industry had the 3rd highest fatality rate among all 9 major economic sectors. • OSHA investigated 7,479 construction fatalities from 1991-2002 • Average 623 fatalities per year on construction sites… over 50 people per month! • Crane Related Fatalities on Construction Sites • Represented 8% of construction site fatalities • Nearly 600 crane related fatalities on construction sites • 84% of crane related fatalities involved mobile cranes with lattice and telescopic booms, truck or crawler mounted cranes/derricks. • Reason for OSHA’s recent re-writing of its crane & derrick standards
OSHA’s Crane & Rigging Fatalities Source: Crane Related Fatalities in the Construction Industry, ASCE’s Journal of Construction Engineering & Management (September 2006) • Using OSHA’S fatality investigations from 1997–2003, the study’s authors analyzed 125 Fatalities to assess: • Proximate Cause of Accident • Victim’s Occupation • Work site’s End Use Function • Construction Operation being Performed by the Crane • Evaluation of Safety Program of Victims’ Employers • Union vs. Non-union • Type of Crane involved in the Fatal Event • Number & Type of OSHA citations by proximate cause • Training & Certification of Operators • Experience of the Victim • Presence of a Competent Person on Site • Type of Rigging
OSHA’s Crane & Rigging Fatalities Source: Crane Related Fatalities in the Construction Industry, ASCE’s Journal of Construction Engineering & Management (September 2006) • Proximate Causes of OSHA Fatalities involving cranes & derricks during lifting operations. • Failure of Boom/Cable • Crane Tip Over • Electrocution • Struck by Load (other than failure of boom/cable) • Falls • Crushed During Assembly & Disassembly of Lattice Booms • Struck by Cab/Counterweight • What didn’t Cause any OSHA Fatalities: • Two blocking • Takeaway from this: Crane Manufacturers play a significant role in minimizing fatalities by developing safety devices
OSHA’s Crane & Rigging Fatalities – Causation Source: Crane Related Fatalities in the Construction Industry, ASCE’s Journal of Construction Engineering & Management (September 2006)
OSHA’s Crane & Rigging Fatalities - The Victims Source: Crane Related Fatalities in the Construction Industry, ASCE’s Journal of Construction Engineering & Management (September 2006) • Occupations of Fatality Victims: • Crane Operator = 10% • Rigger/Laborer = 54% • Ironworker = 9% • Other General occupations including carpenters, welders, masons, truck drivers, etc = 21% • Considering the Proximate Cause of the Fatalities … • The most commonly killed worker was always the Rigger/Laborer • Ironworker fatalities were caused almost exclusively by being struck by the load • Nearly ½ of crane operator fatalities occurred when cranes tipped over • Skilled vs Unskilled Victims • Fatalities to Ironworkers and Crane Operators were far less than unskilled workers • Study doesn’t detail union vs non-union

OSHA’s Crane & Rigging Fatalities – Serious Citations Source: Crane Related Fatalities in the Construction Industry, ASCE’s Journal of Construction Engineering & Management (September 2006) Items in Red = Serious Citations Common in NBIS Data
OSHA’s Crane & Rigging Fatalities – Conclusions Source: Crane Related Fatalities in the Construction Industry, ASCE’s Journal of Construction Engineering & Management (September 2006) • As a result of this OSHA study, the authors concluded: • Crane operators and riggers should be qualified & re-qualified every 3 years thereafter • Crane safety training must be provided to specialty trade crafts before they are allowed to work around cranes during lifting operations. • A “diligent” competent person should be in charge of all aspects of lifting (in accordance with as defined in 29CFR 1926.32f ) • OSHA should improve its system of collecting information during fatality investigations • WE AGREE! • But, we also recognize that we have different data!
OSHA’s Fatality Data vs. NBIS Accident Data • Sample Size of Data • OSHA data only includes 125 crane accidents over 7 years • NBIS data includes appx 500 crane accidents in 1year alone • Severity of Injury & Type of Damages • NBIS analyzes all types of bodily injuries, not just fatalities • NBIS includes property damage claims, not just bodily injury claims • Type of Victim • OSHA data may not properly characterize different types of Victims (i.e. Ironworker vs Rigger) • No Signalmen • Lumps together different “general occupations” • Sophistication of Crane Operator & Crane Company • NBIS data is exclusive to experienced crane & rigging companies & operators • OSHA data includes C&R specialists but also generalists like GC, tree companies, etc • Mobile Crane – Auto Motor Vehicle Accidents • NBIS includes those often occurring accidents going to & from a jobsite • Actual vs Potential Exposure • NBIS analyzes not just actual catastrophic accidents but potential catastrophic damages from “minor” accidents • Location of Accident • NBIS data includes All Crane Related Accidents not just construction sites
OSHA Data vs NBIS Data - Similarities • Overload Conditions are a frequent cause of Structural Failures to Boom & Crane Stability/Tipping • Rigging Failures are very common • Crane Stability Issues are very common • Being Struck by Load is very common • Common cause: Load dropping • Common cause: Rigging Failure • Assembly-Disassembly Accidents are very common • Cause of both High Frequency of Accidents & High Exposure Damages • When electrocutions do occur, the most common cause is similar: failure to maintain required clearance • Lattice boom cranes are involved in more accidents than telescoping boom cranes
OSHA Data vs NBIS Data –Differences • Common Causes unique to OSHA Data • Often reflects inexperience of generalists involved in crane operations • Examples: • Structural Failure of Crane • 12% of OSHA fatalities • Improper Assembly & equipment damage • Appx 10% OSHA fatalities • Struck by Cab & Counterweights • Electrocution is far more common in OSHA data • 27% of OSHA Crane Related Fatalities • Boom contact & cable contact are far more common in OSHA data • Common Causes in NBIS Data • Reflecting unique nature of lifts done by Crane Experts • Often indicative of conditions outside the Crane Operators’ Control • Examples: • Wind Related Accidents significant with NBIS • Only 1.6% of OSHA data • Falls
