Utility Worksite Safety Articles

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.

Is 100 percent cotton protective in an electric arc flash? While lab tests say so, real life experiences say no!

It is widely understood that clothing made from non-flame resistant synthetic fabrics, such as polyester, nylon and polyester/cotton blends, are not appropriate when working on or near electrically energized parts and equipment. If these garments are exposed to an electric arc flash, they can ignite, melt and drip, which can lead to severe contact burns to the skin. In fact, the OSHA 1910.269 and NFPA 70E standards prohibit this type of clothing.

The pros and cons of single-point equipotential grounding, as opposed to working between your grounds or bracket grounding, has generated a lot of discussion. As found in IEEE-1048 Guide for Protective Grounding of Power Lines, single-point equipotential grounding is becoming more simply and accurately referred to as worksite grounding.

One of the significant risks that many organizations take in managing their confined spaces is to try to sort spaces into permit-required and non-permit spaces. Many times the only thing separating the two is a shaky assumption. The characteristics of many spaces can change, increasing the risk. The best programs I have observed treat all spaces on-site as if they were permit spaces. But what exactly is a Permit Required Confined Space?

A simple and effective system for ensuring proper fall protection.

The development of an effective fall protection program has long been a tough issue to deal with. Many of the hazards that utility workers face often seem impossible to provide adequate protection for without introducing some other unsafe condition. And once systems are developed, getting workers to use them is another problem.

What do a pain in the neck, back or shoulder have in common?
Unsafe work behaviors.
