Unfortunately, I have to be the bearor of bad news here. Luckily most of the companies I've worked for used "tech" toes, not steel toes, but I have had to use the steel also.
but look at this letter from OSHA on the subject:

Dear Mr. Wayne Marryatt:

The Directorate of Compliance Programs received your undated letter on June 15 that requested information about protective footwear>>.

OSHA does not generally consider the wearing of steel-toe shoes by electrical tradesmen to be hazardous, so long as the conductive portion of the shoe is not in contact with the employee's foot and is not exposed on the outside of the shoe. One option you and your employer may wish to consider is the purchase of safety <<footwear>> that has been manufactured in accordance with section 4 "Electrical Hazard <<Footwear" of the American National Standards Institute (ANSI) Z41 document. Enclosed are copies of the OSHA and ANSI standards that are applicable to your inquiry.

Your letter has been forwarded to the OSHA Regional Office that has the jurisdiction for your workplace.

Should you need further assistance the OSHA Regional Office, VI, is located at:

525 Griffin Square Building
Room 602
Dallas, Tx. 75202
214-767-4731.


We appreciate your interest in employee safety and health.

Sincerely,
