After being confronted with evidence by a Senate committee, Terrence M. Scanlon, who is awaiting confirmation of his appointment as chairman of the Consumer Product Safety Commission, has said he used a federal employe and government equipment to handle personal business on several occasions, according to documents released yesterday.

Scanlon was investigated by the General Accounting Office after being accused by Joan Claybrook, president of the Public Citizen lobby, of using government resources for personal work and antiabortion activity.

In response to Claybrook's allegations, Scanlon had repeatedly denied to GAO investigators and in previous letters to the committee that he used his staff and other government resources for personal work.

But Sen. John C. Danforth (R-Mo.), chairman of the Commerce, Science and Transportation Committee, told Scanlon in a letter Thursday that a CPSC employe had identified numerous instances in which Scanlon used a federal employe for personal business, including letters typed on behalf of the antiabortion movement.

In response to Danforth, Scanlon said in a letter Friday that "my best recollection is that, over the three-year period I have served at the commission, this employe did type or copy a personal letter or document for me on occasion."

"However, these occasions were very r of tasks dealt with private business transactions, usually involving some typing and Xeroxing," said the senators' letter to Scanlon on Thursday
