The basic regulation, in Section 1910.212, states that any machine that creates a hazard must be safeguarded to protect the operator and other employees. OSHA can also cite violations by referencing other standards such as the ANSI (American National Standards Institute) B11 series. The following is a list of each ANSI B11 Series Standard available at the printing of this publication.

Note: These are NOT OSHA regulations. However, they do provide guidance from their originating organizations related to worker protection.
