OSHA says in 1910.1200(g)(9) that the sheets may be kept in any form. If the electronic work station is in the employee’s work area, and the employee knows how to access them, then maintaining the sheets on a computer would be in compliance. If the SDSs can be accessed only out of the employee’s work area(s), then the employer would be out of compliance with paragraphs 1910.1200(g)(8) or (g)(9). Also, if the access is only in a supervisor’s office that may be locked at certain times when employees may need to access the sheets, that would not be in compliance.
