Utility Tech Helps Reduce Hazard Awareness Delay for Field Workers

A new category of grid intelligence technology called Active Grid Response (AGR) is helping utility companies close the 'hazard awareness delay' gap that has long put field workers at risk when responding to electrical faults. AGR uses sensors on utility poles to monitor conditions in real-time, providing dispatchers and troubleshooters with detailed data about the location and nature of a problem before they are sent to investigate. This allows for better hazard assessments, safer response procedures, and faster resolution of issues that could threaten public safety.

Why it matters

Utility field workers have historically faced significant risks when responding to electrical faults, as they are often sent into unknown hazardous conditions with limited information. This 'hazard awareness delay' has made it difficult for employers to comply with OSHA safety standards that require detailed hazard assessments before work begins. By providing real-time data on the location and nature of issues, AGR technology is helping utilities better protect their workers and the communities they serve.

The details

AGR uses multiple sensors deployed on utility poles to monitor electrical, physical, and environmental conditions in real time. These sensors can detect pole tilt, vibration patterns, temperature changes, vegetation contact, and even the audio signature of an arc flash. When a fault occurs, dispatchers receive specific data on the location, fault type, and severity before troubleshooters are sent out. This allows them to build hazard assessments in advance based on actual data rather than assumptions. The technology has proven valuable during severe weather events, enabling utilities to identify structural failures and other hazards before they escalate into electrical faults or fire risks.

• AGR technology has been adopted by several of the largest utility companies in the U.S. over the past few years.

What’s next

Utility companies are continuing to invest in and deploy AGR technology across their grids to improve worker and public safety. Safety leaders are encouraged to advocate for these investments and ensure they have a seat at the table when grid modernization decisions are made.
