Re: Whether OSHA standards prohibit using two power hoists wired together to a single control; whether a minimum of two persons are required to be on board a two-point suspended scaffold.

Dear Mr. Hogne:

This is in response to your e-mail submitted January 26, 2005,1 to the Occupational Safety and Health Administration (OSHA). You requested that OSHA address the use of power-operated hoists on two-point suspension scaffolds and the whether at least two persons must always be on board.
