Clarification to "Pilot measurements of ELF contact currents in some electric utility operations."
J Occup Environ Hyg 2007 Jul; 4(7):D65-D66
We wish to offer several clarifications to our recently published article on measurements of contact currents on electric utility workers. (1) This article used a recently developed contact current meter (CCM) that logs voltage differences between the extremities (2) in order to assess personal exposures to contact currents in a sample of electric utility occupations. After our article was accepted for publication, an investigation of the CCM's accuracy in various electric utility environments was published as a report. (3) This report identified several sources of error that affect the results in our article. In this letter, we discuss the implications of Bracken's findings on the results in our article and the future use of the CCM for assessing exposures to contact currents and electric fields.
