Deliverables on Safety

Summary of past deliverables related to public and worker safety

Recent deliverables on distribution safety are highlighted below.

2021

For meeting results, utility presentations, and other updates from 2021, see here.

Arc-Flash Analysis Guide

This deliverable is an online, multimedia reference. Safety personnel, work-methods personnel, and protection engineers can use this information to evaluate and update their arc-flash hazard analyses. Additions and updates in 2021 include:

Grounding and Personnel Protection Practices

This deliverable covers grounding and personnel protection for scenarios involving overhead work, underground work, and work around vehicles. Safety personnel and standards engineers can use this information to design better approaches to grounding and personnel protection. Additions and updates in 2021 include:

Personnel Protection Equipment and Technologies

This deliverable covers evaluations of technologies and equipment for personnel protection. This includes performance of personal protective equipment (PPE). For 2021, the additions includes tests of:

2020

For meeting results, utility presentations, and other updates from 2020, see here.

Arc-Flash Analysis Guide

This deliverable is an online, multimedia reference. Safety personnel, work-methods personnel, and protection engineers can use this information to evaluate and update their arc-flash hazard analyses. Information may also inform practices and help line workers to understand risks. The site includes reference material and videos. An online app and spreadsheets are included to aid in the analysis of hazards.

Grounding and Personnel Protection Practices

This deliverable covers grounding and personnel protection for scenarios involving overhead work, underground work, and work around vehicles. Safety personnel and standards engineers can use this information to design better approaches to grounding and personnel protection. The information can also be shared with line workers to reinforce the hazards and how to avoid them. The site includes reference material, videos, and online apps to calculate hazards.

Detecting and Preventing Live, Downed Conductors

Several resources are provided based on research on detecting and preventing live, downed conductors. The site includes reference material, videos, and online apps. Protection engineers, operations groups, standards engineers, and safety personnel can use this information to implement approaches to detect and prevent downed conductors.

Application to Verify Live-Line Coverup: Feasibility Analysis

This report considers the feasibility of developing an application that could verify and reinforce proper use of coverups. Several approaches to developing this concept into an application are reviewed. Scenarios were staged with good and bad uses of coverups to evaluate ways to create training data for machine-learning models. Utilities can use these results to evaluate their plans for deploying digital-worker technologies.

Personal Voltage Detectors: Tests in Utility Distribution Scenarios

Results from staged tests are used to quantify the performance of voltage detectors. Detectors were tested near energized downed conductors, an energized vehicle, and an overhead line (from the ground and from the air). This report can be used to help utilities select appropriate personal voltage detectors. Results can help identify where these detectors work best, as well as to understand their limitations.

Electrical Performance of Plastic Guards: Distribution Safety

This report documents tests on the electrical performance of used plastic guards. These tests allowed comparison of physical condition to electrical performance. Utilities can use the results to help determine inspection and replacement strategies.

Impacts of 5G Equipment on Distribution Practices

This report documents industry-wide requirements for telecom attachments. These requirements include allowable structures, clearance requirements, and other attachment limits. Issues related to worker safety are covered—including radio frequency exposures. Finally, safety-related industry needs for workers are identified.
