I’ve written about equipotential grounding for Incident Prevention magazine dozens of times over the past 15 years, both in this column and in the Q&A. Those articles have had thousands of views on Incident Prevention’s website, which suggests that their messaging should be getting through to industry employers and lineworkers – but my experience says […]

Q: I’m a municipal utility substation engineer, and I’m hoping you can help me with this question: Does an engineer taking photos in a substation fall under the OSHA 29 CFR 1910.269 work rules? A: The simple answer is yes. No matter your training or education, if you must be inside the fence to take […]

Q: Here in Australia, we recently read Jim Vaughn’s “Trainer the Trainer 101: Substation Entry Policies” (https://incident-prevention.com/blog/train-the-trainer-101-substation-entry-policies/). We have a 415-volt substation on-site; its doors and cabinets are locked. However, we are not comfortable allowing entry to the substation without some control over who is able to enter and the qualifications they must have. Do […]

Employers in our industry must have policies and procedures in place that align with OSHA’s qualified worker requirements. Each employer also must be able to defend its interpretation of those requirements. Many can’t do it. This is something I come across in almost every OSHA and civil litigation case I work on. Whether it’s General […]

Q: We are looking for some direction and opinions regarding SF6 gas switches. The SF6 switches we use on our campus are older and starting to pose problems. Some are leaking and others are very difficult to operate. Can you help? A: Sulfur hexafluoride, or SF6, isn’t a topic or problem we can effectively deal with […]

I perform audits of both utilities and contractors. When I work with them to do those audits, we include trucks and trailers. The trailers I’m talking about here are not the box vans behind tractors, but the general-duty trailers used to haul trenchers, backhoes, wire reels and padmount transformers. It’s no surprise that the trailer […]

A few years ago I came upon a crew using 6-inch chocks to hold back a 38-ton crane truck. I told the crew I was happy that they were making an effort at compliance, but I had to ask them, “Why do we place chocks under a truck’s wheels? Is it to comply with our […]

Q: How high can we stack poles in a pole yard? I can’t find any references in OSHA or ANSI C2/the National Electrical Safety Code. Is there a standard? A: Your question provides us with an example of when a standard governing our industry is not necessarily found in the National Electrical Safety Code, OSHA […]

This isn’t the first time – and I suspect it won’t be the last time – that I have addressed the question of what work can be done under the digger derrick exemption found in OSHA’s Cranes and Derricks in Construction standard (29 CFR 1926 Subpart CC). The issue has come up constantly since the […]

Q: Why don’t all utilities use rubber gloves with hot sticks? A: One of our supporting consultants sent us this question that he gets all the time. The answer is simple: There is no requirement in any standard to use rubber gloves with hot sticks. Rubber-gloving hot sticks has evolved as a work practice in […]
