Our signs are UL Listed.  What does it mean?

Underwriters Laboratories Inc (UL)

UL’s safety certification services include testing, evaluation and factory surveillance of products to national, regional and international safety standards. These certifications enhance the safety of products, as well as the public’s confidence in their compliance. Consumers, retailers, insurers, distributors and regulators recognize the familiar UL Mark as a trusted symbol of safety.

WE ARE “UL” CERTIFIED, all our electrical signs will have UL Labels.

History of Underwriters Laboratories

In 1894, William Henry Merrill, an electrical engineer, founded UL. Prior to founding the company, Merrill had served as an electrical inspector for the Boston Board of Fire Underwriters, an electrician for the Chicago Underwriters Association and as an electrical inspector for the Chicago World’s Fair. At the World’s Fair, Merrill was hired to examine the electrical safety of the Columbian Exposition’s Palace of Electricity, the first large-scale use of electricity for illuminating. The proliferation of untamed DC circuits and the new, higher voltage AC currents caused a great deal of concern and a rash of fires. Critics questioned if the new technology would ever be safely harnessed. Merrill assured that it could be with the proper care, handling and understanding of its potential hazards.With this goal in mind, Merrill conceived of the idea of an independent testing facility that could render expert opinions concerning fire hazards and certify electrical devices. At first rejected, the need for such a laboratory became clear and UL came into being. From that point forward, UL has been a pioneer and leading authority in testing and creating safety standards.
