Product Safety Engineering Society
of the
IEEE Long Island Section

The Product Safety Engineering (PSE) Society targets Long Island design professionals and design engineers interested in electrical product safety. The Society addresses safety engineering for equipment and devices used in the scientific, engineering, industrial, commercial and residential arenas. It allows engineers and other technical professionals an opportunity to discuss and disseminate technical information, to enhance professional skills, and to provide outreach to engineers, students and others with an interest in the field.

Safety Considerations in Power Supply Design
Louis Diana - TI
2014 May 22

Increasingly, the responsibilities of a power supply designer extend beyond merely meeting a functional specification, with designing to meet safety standards an important collateral task. Since all commercial and home-use supplies must eventually be certified as to safety, knowledge of the requirements should be a part of every designer’s repertoire. This simplified overview has been prepared with the collaboration of Underwriters Laboratories, to provide a basic introduction to the issues and design solutions implicit in assuring the safety for both the user and service personnel of your power supply products, as well as easing the certification process.

Anatomy of an Effective Human Factors Engineering Program

Timothy R. McEwen & Stephanie Alpert - Underwriters Laboratories
2014 April 24

The comprehensive application of human factors engineering (HFE) in product development is an imperative. “User-friendliness" helps ensure that products are operated in a safe manner and helps foster a product's marketability. In some domains, such as the medical device industry, there is also a regulatory requirement to perform HFE en route to a final, validated design. In an effective HFE program, manufacturers perform detailed use-related risk analyses; revise their designs as needed to reduce risk to acceptable levels, and conduct validation tests to demonstrate that users will not commit potential harmful use errors.

Henry Ford's Universal Code

Bill Levinson - Levinson Productivity Systems
2013 July 10

Henry Ford achieved world-class results in the language of both money and productivity. These included a return of $125 on the dollar for his investors, an annual wage growth of 7.2 percent for his employees, and expansion of the US economy into the most prosperous on earth. Only after he achieved these results did he write books that show how he did it. Ford attributed his success to a universal code that is suitable for all economic activities, including services as well as businesses. He applied it successfully to mines, railroads, and a hospital as well as to the manufacture of automobiles and tractors.

Nothing has changed during the past century to invalidate this universal code. Most of our country's economic problems, including the 2008-2009 stock market crash, stem from failure to conform to it. This universal code consists of a simple triad of impartial economic, scientific, and behavioral laws. Economic law says no system or supply chain can disburse more wealth than it produces. Manufacturing science, and many principles apply to services as well, allow the system to produce more wealth through the elimination of waste. Behavioral law mandates a square deal for all supply chain stakeholders including customers, suppliers, and workers. The laws are impartial (they belong to no ideology or political position), inarguable, and also synergistic. The latter means that success depends on the understanding and application of all three.

Electric Utility Distribution System Design & Safety Concepts

George Ello - National Grid
2010 April 20

Electric distribution systems involve many aspects of safety. Basic concepts of distribution system design include grounding as well as step and touch potentials. Protective devices and fault clearing protect against damage due to electric faults or short circuits, and are as essential to a utility as they are to a building distribution system. Voltage issues such as back-feed, swells and lightning are also explored.

Distributed generation and cable testing also present safety challenges. Small generators (Solar PV) impact existing protective relaying, circuit voltages, other customers and safety. Distribution cable requires special test techniques, such as to locate faults on underground cable.
