Dear Mr. Demos:
This is in response to your recent letter concerning the accuracy of definitions.
Employees engaged in the Construction of electric transmissions and distribution lines are required to use hydraulic tools that contain an insulating oil and nonconducting hoses. The "insulating type" as used in my April 3, 1978, letter means a fluid that will not conduct electricity; "nonconducting" as used in 29 CFR 1926.951(f)(4)(i) means a hose meeting the requirements of the American National Standards Institute (ANSI) J6.1-1950 (R1971) for rubber insulating line hose.
The requirements for the use of insulating type fluids, and nonconducting hoses, is to protect an employee from electrocution by an accidental contact of the hose with an energized line.
If I may be of any further assistance, please feel free to contact me.
