Tricks of the Trade to Improve the Trenching Environment

This is the final installment in a four-part series on trenching and excavation. “Trenching by the Numbers” (http://incident-prevention.com/blog/trenching-by-the-numbers), the first article in the series, presented a simple method for recalling OSHA’s trenching and excavation requirements. The second article focused on soil mechanics (http://incident-prevention.com/blog/soil-mechanics-in-the-excavation-environment), taking an in-depth look at the behavior and characteristics of different soil types and their relationships with water and air. In the June 2016 issue of Incident Prevention, I...

Train the Trainer 101: Practical Personal Grounding in Underground Work

Incident Prevention has been covering personal protective grounding (PPG) for many years. Most of the emphasis has been on overhead applications for transmission and distribution. Lately, however, iP and many consultants associated with the publication have been receiving more and more inquiries from utilities seeking to understand the issues related to PPG applications in underground. Part of the issue with PPG is that, as I mentioned, most training and rules seem to coalesce around overhead applications. The majority of the written standards – both OSHA and consensus – are found in sections...

Protective Systems for Trenching and Excavations

This is the third installment of a four-part series on trenching principles. “Trenching by the Numbers” (http://incident-prevention.com/blog/trenching-by-the-numbers), the first article in the series, presented a simple method for recalling OSHA’s trenching and excavation requirements. The second article focused on soil mechanics (http://incident-prevention.com/blog/soil-mechanics-in-the-excavation-environment), taking an in-depth look at the behavior and characteristics of different soil types and their relationships with water and air. In this article, we will discuss the four different protective...

Trenching by the Numbers

By and large, organizations directly provide the training and other resources needed for the development of their foremen and crew chiefs. Such training tends to be built around two components: following the standards set forth by OSHA and other regulatory agencies, and adhering to organizational policies and procedures. This is a great approach but perhaps an incomplete one. Truly impactful safety training typically includes a third component: sharing of personal experience. For instance, I once observed a training session in which the instructor drew from his experiences during a discussion...

Train the Trainer 101: Practical Underground Safety: Handling Neutrals and Rescue

Over the years I spent as a lineman, I did my share of underground installation and maintenance work. During my years in safety, I have seen the expansion of safety processes associated with underground, especially in response to the most recent OSHA changes. Not all of the changes have been effective, and that’s why we’re now going to spend some time addressing several underground safety questions Incident Prevention frequently receives. We’ll look at the rules and practices and what works from a practical perspective. Handling URD NeutralsThis will not come as news to most of you, but for...

August 2015 Q&A

Q: I’m wondering about an issue with a third-party safety analysis required by one of our clients. We are required to satisfy their safety requirements, including creating programs and safety manual changes worded to meet their criteria. I have issues with the required changes because they don’t fit into our safety program. A: You are not alone in your concerns. OSHA issued a warning about this exact topic, and it was a reason for changing the language in the proposed rules from June 2005. In the proposed rule, 29 CFR 1926.950(c) required contractors to follow a utility’s work rules...

Notes From the Underground

In the May/June 2005 issue of Incident Prevention the cover article, “Why Single-Point Grounding Works,” generated a lot of inquires about single-point worksite grounding in underground installations. The most frequently asked question was, “How do we create an equipotential zone for underground worksites?” I received inquiries from California to Maine, North Dakota to Florida. There were so many that IP asked if I could immediately address underground protective grounding for employees in this issue. OF BONDS AND BOUNDARIES Let’s begin with the practicality of...
