OSHA 1910.303 and ANSI/NETA MTS: Practical Electrical Maintenance Best Practices

Frequently Asked Questions

What does OSHA 1910.303 require for electrical maintenance?

It requires electrical equipment in the workplace to be maintained in a safe condition, not just installed correctly at the start. The post explains that inspection and maintenance should be planned, documented, and followed through when equipment condition can affect safe operation.

How does ANSI/NETA MTS help with an electrical maintenance program?

ANSI/NETA MTS gives teams a structured framework for deciding which assets need maintenance and testing, how often to inspect or test them, and how to record and review results. It helps facilities move away from informal or reactive maintenance toward a more consistent process.

What should be included in a strong electrical inspection and maintenance program?

The post says a strong program starts with a current asset inventory and a risk-based schedule. It should also include defined inspection frequencies, preventive maintenance tasks, testing scopes, escalation criteria for deficiencies, and trending of test results and recurring issues.

What records should EHS managers keep for electrical maintenance?

Records should show what equipment was inspected, maintained, or tested, when the work happened, who performed it and their qualifications, what deficiencies were found, and what corrective actions were completed. The program should also show what equipment remains in service with open issues and what interim controls are in place.

How should electrical shutdown work be planned?

The post recommends coordinating shutdowns early with operations, maintenance, and supervision so work is not rushed. Planning should define the affected equipment, verify drawings and isolation points ahead of time, allow enough outage time, clarify decision authority for added defects, and communicate restart and handoff expectations.
