Dear Mr. Ghormley:

Thank you for your letter of April 6, 1973, regarding the use of aerial baskets.

Paragraph [1926.453(b)(2)(iv)] places limitations on working areas associated with the use of an aerial basket. It does not address the subject of using the basket to lift employees to an elevation and then climbing to a higher elevation.

Paragraph [1926.453(b)(2)(x)] prohibits the wearing of climbers when working from a basket. It does not address the use of the basket to lift personnel. American National Standards Institute (ANSI) A92.2 is the basic support material for this standard and no reference is made to the usage to which you refer.

If the basket is properly protected so that the dielectric capabilities will not be degraded, there does not appear to be any objection to the utilization of the aerial basket as suggested.

The number of operating personnel required in connection with the operation of an aerial basket is not specified, however, good safety practices would require a man on the ground when an employee is in the air working on lines.

There are several areas which could be hazardous to the employee when attempting to enter or leave the basket, and could subject him to shock and fall hazards.

Therefore, utilization as you outlined should be given careful consideration and procedures should be developed to protect the employee during such operations.

Sincerely yours,


Carlyle F. Bunn
