Why use a qualified observer?

The majority of workplace injuries arise from worker behavior: mistakes, errors in judgment or lapses in attention. Having a qualified observer on site helps offset or eliminate these behaviors.

A qualified observer helps ensure that clearances are maintained, proper equipment is used and effective cover up is installed.

A qualified observer can help: 

• Eliminate unintentional contact with energized components while working on, or near, lines and equipment
• Eliminate injuries from unrecognized hazards or changes in conditions

(The term “effective cover up” is used to describe the installation of phase-to-phase rated insulating protective cover on energized conductors or equipment of different potentials when the lineworker is within reaching distance or in areas extended by handling conductive objects.)

Side notes

• The qualified observer shall not perform other duties and all work shall stop if the qualified observer can no longer perform observer duties.
• The observer shall have the authority to stop work if needed.

Qualified observer qualifications

A qualified observer shall be designated to provide timely warning while working: 

• On or within the minimum approach, including extended reach, of energized conductors or equipment (systems at and above 600V)
• When using mechanical mobile equipment near energized conductors
• When moving energized conductors

(The term “extended reach” is used to describe being within 5 feet of energized conductors or equipment or having a conductive object within 5 feet of energized conductors or equipment.)

Prior to work commencing, a member of the crew who is an electrically qualified worker and can meet the listed criteria shall be identified to act as the qualified observer.

A qualified observer is defined as is an electrically qualified worker that can identify all hazards present to the crew working energized conductors. The qualified observer shall be capable of: 

• Distinguishing exposed live parts
• Identifying nominal voltages
• Determining minimum approach distances
• Knowing safe work practices for working on, or near, energized lines and equipment
• Recognizing electrical hazards to which workers will be exposed and knowing skills and techniques to control those hazards
• Rendering immediate assistance in case of an accident
