Title: What is UL 1187 and UL 1346? A Guide to Electrical Safety in Commercial and Industrial Settings

When it comes to ensuring electrical safety in commercial and industrial settings, two key standards come to mind: UL 1137 and UL 134As a critical component of the Underwriters Laboratories (UL) family of standards, both of these documents provide guidelines for the construction, installation, and maintenance of electrical equipment used in hazardous locations. In this article, we will explore the purpose and importance of UL 1137 and UL 1346 in ensuring electrical safety in these settings.

What is UL 1137?

UL 1137 is a technical standard established by UL, which provides guidelines for the construction, installation, and maintenance of electrical equipment used in hazardous locations. The standard aims to prevent fires, explosions, and other accidents caused by the ignition of hazardous substances such as flammable gases, vapors, liquids, or combustible dust particles due to electrical equipment.

UL 1137 covers various aspects of electrical safety, including the design and testing of equipment, selection of suitable materials, proper wiring, grounding techniques, and the use of protective measures such as enclosures and seals. Compliance with UL 1137 ensures that electrical equipment can be safely operated in potentially dangerous environments.

What is UL 1346?

UL 1346 is a widely recognized standard in the technical field, especially in the realm of electrical products. It is a standard specifically designed for safety requirements for isolated power systems in healthcare facilities. The primary goal of UL 1346 is to ensure the safe usage of electrical equipment and minimize potential hazards in medical environments.

In the mid-1990s, healthcare facilities started using isolated power systems as an alternative to grounded systems. However, concerns arose regarding the potential risks associated with isolated power system installations. This led to the development of UL 1346, which aimed to set forth comprehensive safety guidelines for isolated power systems in healthcare facilities.

Conclusion:

UL 1137 and UL 1346 are two crucial standards for ensuring electrical safety in commercial and industrial settings. Compliance with these standards is essential for the safe and effective use of electrical equipment in hazardous environments. By understanding the guidelines and requirements set forth by these documents, manufacturers, installers, and operators can minimize the risk of fires, explosions, and other accidents caused by electrical equipment.
