Dear Mr. White:

This is in response to your April 12, 2000 letter in which you asked the Occupational Safety and Health Administration (OSHA) if there are any OSHA regulations that specify how a concrete mixer must be guarded and if the dimensions of the guard's openings are specified.

Requirements for leaving construction equipment and powder-actuated tools unattended on a construction building site; impalement protection from reinforcing steel for masonry workers on a scaffold.
