19

Qualified EvaluatorA person who has demonstrated that he/she is competent in accurately assessing whether individuals meet the qualification requirements for signal persons or riggers, per 296-155-53302 and 53306.

Third Party Qualified Evaluator– means an entity which is independent from the signal person’s or the

rigger’s employer.

Employer (not a third party)– means a person employed by the signal person’s or the rigger’s

employer.

20

Signal Persons Qualifications 296-155-53302

21

Signal Person (Feb 1,2012)

This applies to construction activities which involve cranes and powered industrial trucks which have been configured to hoist and lower by means of a winch or hook

Who meets the requirements of WAC 296-155-53302

22

Signal Person Required

– Point of operation is not in full view of operator– View of direction of travel is obstructed– Site specific safety concerns which the operator

or person handling the load determines it necessary

– Working near energized power lines and a dedicated spotter is used, in addition to other responsibilities they must also meet the signal person qualifications

– Any time someone is signaling a crane

Signal Person Qualifications

Qualification Requirements:– Know and understand the type(s) of signals

which will be used– Competent in the application of the type of

signals used– Have a basic understanding of equipment

operation and limitations, crane dynamics, and boom deflection

24

Signal Person Qualifications

Qualification Requirements:– Demonstrate knowledge and skill through

a verbal or written test, and through a practical test

– Documentation from qualified evaluator• A Third Party Qualified Evaluator• An Employer Qualified Evaluator

– An assessment by an Employer's Qualified Evaluator under this option is not portable

25

Qualified EvaluatorA person who has demonstrated that he/she is competent in accurately assessing whether individuals meet the qualification requirements for signal persons or riggers, per 296-155-53302 and 53306.

Third Party Qualified Evaluator– means an entity which is independent from the signal person’s or the

rigger’s employer.

Employer (not a third party)– means a person employed by the signal person’s or the rigger’s

employer.

Power Line Safety WAC 296-155-53408

34

Power Line Safety Requirements If the crane or rigging could get closer than 20/50 feet to an

energized power line there are new safety requirements which apply. 

If the crane or rigging can not get closer than 20/50 feet to the line even if the crane is operated at its maximum working radius, the 20/50-foot requirement is satisfied.

Minimum approach distance:

Up to 350kv 20 Feet

Over 350KV 50 Feet

35

Power Line Safety

Crane assembly/disassembly below energized power lines is prohibited.

Crane assembly/disassembly inside Table 4 is prohibited.

36

Operation of Crane/Derrick

Identify the work zone by demarcating boundaries. (flags, or devices/limiting)

Determine maximum working radius/360 which includes rigging & load. If could get closer than 20 ft of a power line.

Employer must meet requirements in Option (1)(2) or (3)

Power Line Safety Requirements Crane operations near power

lines, use one of 3 Options– Option 1 - Deenergize & Ground

Power lines

– Option 2 - Maintain 20/50 foot clearance

– Option 3 - Obtain power line voltage from Utility Owner/Operator and ensure the crane or rigging does not get closer than the distances listed in Table 4

38

Power Line Safety Requirements

Work Zone360 degrees around the crane (maximum working radius) Demarcate work zone boundariesand prohibit the operator fromoperating the crane past those boundaries

Power Line Safety Requirements Options 2 and 3 also require the

following: Installing an elevated warning line or

barricade 20/50 feet from Power Line, and

Implement at least one of the following:

• Proximity alarm (OSHA exempt)

• Dedicated spotter• Range control warning device• Range Movement limiter• Insulating link (OSHA exempt)

40

41

Could you get within 20 feet of a power line?

YES NO

Option #1 Deenergize & Ground

Encroachment Prevention Measures

Option #3Ask Utility for Voltage and Use Table 4 (with minimum

clearance distance)

Option #220-foot Clearance

No Further Action

• Planning Meeting• If Tag Lines are Used, They Must be Nonconductive• Elevated Warning Lines, Barricades, or Line of Signs

PLUS (Choose One):

• Spotter, Warning Device, Range Limiter.

Power Line Safety Requirements (Part L before 2/1/2012)

For energized power lines rated at or below 50kV the minimum approach distance shall be 10 ft.

For lines rated over 50 kV., minimum clearance between the lines and any part of the crane or load shall be 10 feet plus 0.4 inch for each 1 kV. over 50 kV., or twice the length of the line insulator, but never less than 10 feet

42

Power Line Safety Requirements (Current Part L)

Minimum Clearance Distances Table 4
