Most inspection standards for the equipment listed above are established by ANSI (American National Standards Institute). ANSI standards for this type of equipment are defined as 'voluntary recommended practices'. However, OSHA (Occupational Safety and Health Administration) requirements for most industries (utility, telecommunications, electrical, etc.) often reference ANSI standards and state that compliance is mandatory. Therefore, at least within the United States, voluntary ANSI standards may become mandatory for the types of equipment referenced by OSHA. Contact the ML Utilities service team if you are unsure of what inspections are required. ML Utilities is proud to offer annual ANSI inspections at our customers' convenience.
