Construction Crane Safety (new requirements 2010) September 2, 2010
Why? Crane accidents killed an average of 78 people per year between 2003 and 2005 The new standard is located at 0/08/09/ /cranes-and-derricks- in-construction#h-15 0/08/09/ /cranes-and-derricks- in-construction#h-15 OSHA expects the final standard to prevent 22 fatalities and 175 non-fatal injuries each year.
When? Intention to develop the rule in July Used negotiated rulemaking committee consisting both industry and labor. The committee completed its work in Released – July 28, 2010 Published – August 9, 2010 Effective – November 8, 2010 Phased in over four years – August 9, 2014 –Certification of operators phased in over four years. No grandfathering of those past certification.
Key Hazards Four main causes of worker death and injury: Electrocution, Crushed by parts of the equipment, Struck-by the equipment/load, and Falls. (See Subpart M )
Largest Impact Mandatory crane operator certification - qualification 200,000 construction crane operators in the industry OSHA allowing four years to meet the certification requirement. It will take time for certifying organizations to gain enough capacity to cover so many operators.
Other Significant Requirements Use of synthetic slings in accordance with the manufacturers instructions during assembly/disassembly work; Assessment of ground conditions; Procedures for working in the vicinity of power lines. Pre-erection inspection of tower crane parts;
OSHA – State - Local Employers must comply with local and state operator licensing requirements which meet the minimum criteria specified in § Some state had existing Crane standards that exceeded the old standard. In state plan states, please see the rules for that state.
Who Pays? Employers must pay for certification or qualification of their currently uncertified or unqualified operators (a)(4) Reasonable that employees, who have already been sufficiently trained in crane operation and may have many years' experience, certainly need no more than a short preparation to successfully pass the crane operator certification tests. – FR Preamble
Crane or Not Crane? Functional description –Can hoist, –Lower and –Horizontally move a suspended load Forklifts configured to hoist and lower (by means of a winch OR hook) and horizontally move a suspended load are covered Backhoes are excluded even if used like a crane… (c)(2) Forklift with attached boom (c)(8) See if using equipment with a rated hoisting/lifting capacity of 2,000 pounds or less
10 OPTION 1OPTION 1: Accredited testing organization OPTION 2OPTION 2: Employer qualification program OPTION 3OPTION 3: U.S. military OPTION 4OPTION 4: State/local govt license Operator Qualifications and Certifications - 4 Options
11 Operator Qualifications and Certifications (contd) Accredited testing organization YES *5 years Employer Qualification Program NO5 years US Military licenseNO *Set by issuing entity State/local licenseNO * Valid only in entitys jurisdiction Set by issuing entity, not > 5 years PortableValid
Written Certification Tests Administered in any language understood by the operator candidate. Test must cover: –Controls/performance characteristics –Calculate capacity (w/ or w/out calculator) –Preventing power line contact –Ground support –Read and locate info in operating manual –Appendix Q subjects
Practical Examination Must be well designed and sufficiently comprehensive Must have the demonstrated the skills and knowledge needed to operate the equipment safely. An operator's ability to handle unusual worksite conditions, such as adverse weather or working on crowded jobsites, are hazards that are not commonly part of this exam.
Power Lines Step 1: Identify Work Zone –Work Zone = Marking boundaries OR –360 degrees around crane up to maximum working radius –Make the power line hazard assessment
15 Could you get within 20 feet of power line? YESNO Option #1 Deenergize & Ground Encroachment Prevention measures Option #3 Ask Utility for Voltage and Use Table A ( with minimum clearance distance) Option #2 20 foot clearance No further action Planning meeting If tag lines used Non-conductive Elevated warning lines, barricade or line of signs PLUS (Choose one): Proximity alarm, spotter, warning device, range limiter, or insulating link
16 Table A – Minimum Clearance Distances Voltage (nominal, kV, alternating current) Minimum clearance distance (feet) up to 5010 over 50 to over 200 to over 350 to over 500 to over 750 to over 1000 (as established by the power line owner/operator or registered professional engineer who is a qualified person with respect to electrical power transmission and distribution)
Intentionally Working Closer Than Table A Zone Paragraph (b) requires the employer to consult with the utility owner/operator before deciding that it infeasible to deenergize and ground the lines or relocate them. Employer can establish this distance by either having the utility owner/operator determine the minimum clearance distance that must be maintained or by having a registered professional engineer who is a qualified person with respect to electrical transmission and distribution determine the minimum clearance distance that must be maintained.
18 Must show : Staying outside zone is infeasible Infeasible to deenergize and ground Intentionally Working Closer Than Table A Zone All of the following are required: 1.PL owner – sets minimum approach distance 2.Planning meeting – procedures 3.Dedicated spotter 4.Elevated warning line or barricade 5.Insulating link/device 6.Non-conductive rigging 7.Range limiter (if equipped) 8.Non-conductive tag line (if used) 9.Barricades - 10 feet from equipment 10.Limit access to essential employees 11.Ground crane 12.Deactivate automatic re-energizer
Assembly Disassembly Employers must use a qualified rigger for rigging operations during assembly & disassembly Two options: –Manufacturer procedures or –Employer procedures (criteria requirements)
Assembly/Disassembly Supervisor Must understand procedures Review procedures (unless theyve used them before) Check that crew members understand their tasks, hazards Follow manufacturers prohibitions When using outriggers - fully extended or deployed per the load chart
21 A/D supervisor addresses 12 key hazards, including: –Adequate site and ground conditions –Sufficient blocking for load and stability –Suitable boom and jib pick points –Identify center of gravity –Stability for pin removal –Consider wind speed and weather Assembly/Disassembly (contd)
22 The suitability of blocking material Verification of the loads for assist cranes Snagging of cables or components Struck by counter weights Boom hoist brake failure Loss of backwards stability Assembly/Disassembly (contd)
Qualified Rigger (r) Meets the criteria for a qualified person Possession of a recognized degree, certificate, or professional standing, or extensive (rigging) knowledge, training and experience Successfully demonstrated the ability to solve/resolve problems (relating to rigging)
Tower Cranes Employers must perform a pre-erection inspection of tower cranes. Extensive requirements under and other sections. Beyond scope of this presentation Numerous accidents such as Seattle in 85, San Francisco in 89, Manhattan in 08, Hong Kong in 08, New York in 06,
Ground Conditions (b) Ground conditions must be firm, drained, and graded Use supporting materials, Use equipment manufacturer's specifications for adequate support Use equipment manufacturer's specifications for degree of level of the equipment
Controlling Entity (c)(3) Must ensure that ground preparations are safe Must inform the user of the equipment and the operator of the location of known hazards beneath the equipment set-up area (such as voids, tanks, utilities) If there is no controlling entity then the employer that has authority at the site to make or arrange for ground preparations must do so.
27 Signals Signal person – when required: –Point of operation not in full view of operator –View of direction of travel is obstructed –Site specific safety concerns – Signal person qualifications Signal Types: –Hand, voice, audible or new –Only time an operator can use a cell phone is while lifting as part of a planned procedure
28 Signals (contd.) Signal person qualifications 3 rd party qualified evaluator Yes Employer Qualified Evaluator YesNo Qualified howDocumentationPortable
29 Qualification Requirements: –Know & understand signals –Competent in using signals –Basic understanding of crane operation –Verbal or written test + practical test Signals (contd.)
Inspections Modified or Repaired/ adjusted Qualified Post-assemblyQualified ShiftCompetent MonthlyCompetent AnnualQualified Type of Inspection: Who Inspects:
Each Shift Inspection (d) Apparent deficiencies Control and Drive mechanisms Hydraulics Hooks Wire Rope Electrical Ground Conditions Levelness of the crane Operator view All Safety Devices Operational Aids are working
Operators has many requirements. Some highlights are: Must not engage in any activity that diverts his/her attention while operating the equipment, No cell phones (other than when used for signal communications) Must not leave the controls while the load is suspended, (four exceptions) Must verify that the load is within the rated capacity of the equipment (2 methods) Must obey a stop (or emergency stop) signal, irrespective of who gives it. Told of any employee entering the crane work area (a)(3)
Employer Training Employee Training Issues Powerline safety Signal persons Operators Competent Person Qualified Persons Crush Pinch point hazards Tagout for repair Must confirm that the employee understands the information provided in the training Provide the training at no cost to the employee
Work Area Control Train each employee assigned to work on or near the equipment Erect and maintain control lines, warning lines, railings or similar barriers to mark the boundaries of the hazard area (1 Exception)

Further This ppt was prepared by John Newquist as a preliminary aid for the new standard. Please check the OSHA website for Crane Outreach Material that will be developed in the coming months. This is not an official OSHA publication. Those will be on the OSHA.gov website. is my if you see any Brian Sturtecky is our Region V Certified Crane Inspector and has provided key assistance on this standard. He can be reached at Several slides were obtained from the OSHA Training Institute from their Webinar August 30, Every aspect from inspecting, repairing, operating, rigging and signaling these cranes require extensive training. Please take classes with hands on training if you are expected to perform any of these activities. I want to thank Brian, Lisa, Tom, Bill, Cathy for all their assistance in answering questions and providing issues that are coming from the public.
