Presentation Transcript
  • Crane accidents killed an average of 78 people per year between 2003 and 2005
  • The new standard is located at
  • OSHA expects the final standard to prevent 22 fatalities and 175 non-fatal injuries each year.
  • Intention to develop the rule in July 2002.
  • Used negotiated rulemaking committee consisting both industry and labor.
  • The committee completed its work in 2004.
  • 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
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 1926.500-503)
largest impact
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
Other Significant Requirements
  • Use of synthetic slings in accordance with the manufacturer’s 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
OSHA – State - Local
  • Employers must comply with local and state operator licensing requirements which meet the minimum criteria specified in § 1926.1427.
  • Some state had existing Crane standards that exceeded the old standard. In state plan states, please see the rules for that state.
who pays
Who Pays?
  • Employers must pay for certification or qualification of their currently uncertified or unqualified operators. 1926.1427 (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
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….1926.1400 (c)(2)

Forklift with attached boom. 1926.1400 (c)(8)

See 1926.1441 if using equipment with a rated hoisting/lifting capacity of 2,000 pounds or less

operator qualifications and certifications 4 options

Accredited testing organization


Employer qualification program


U.S. military


State/local gov’t license

Operator Qualifications and Certifications - 4 Options


written certification tests
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
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.
1926 1408 power lines
1926.1408 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



Could you get within 20 feet of power line?



Option #1 Deenergize & Ground

No further action

Encroachment Prevention measures

Option #2

20 foot clearance

  • 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

Option #3

Ask Utility for Voltage and

Use Table A

(with minimum clearance distance)


intentionally working closer than table a zone 1910 1410
Intentionally Working Closer Than Table A Zone 1910.1410
  • 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.

Intentionally Working Closer Than Table A Zone

  • Must show:
  • Staying outside zone
  • is infeasible
  • Infeasible to
  • deenergize and
  • ground

All of the following are required:


  • PL owner – sets minimum approach distance
  • Planning meeting – procedures
  • Dedicated spotter
  • Elevated warning line or barricade
  • Insulating link/device
  • Non-conductive rigging
  • Range limiter (if equipped)
  • Non-conductive tag line (if used)
  • Barricades - 10 feet from equipment
  • Limit access to essential employees
  • Ground crane
  • Deactivate automatic re-energizer

Assembly Disassembly
  • Employers must use a qualified rigger for rigging operations during assembly & disassembly
  • Two options:

  • Review procedures (unless they’ve used them before)
  • Check that crew members understand their tasks, hazards
  • Follow manufacturer’s prohibitions
  • When using outriggers - fully extended or deployed per the load chart

  • 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 website.
  • is my email if you see any errors
  • 312-353-5977
  • Brian Sturtecky is our Region V Certified Crane Inspector and has provided key assistance on this standard. He can be reached at 312-353-2220.
  • Several slides were obtained from the OSHA Training Institute from their Webinar August 30, 2010.
  • 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.
