Learning objectives Review considerations for light fixture selection in hazardous-classified areas. Understand why specific light fixtures are selected for maintenance purposes. Learn about light fixture selection for heavy-duty/rugged environments. Lighting insights After reading this article, facility managers, engineers and designers can make more informed light fixture selections to enhance safety and extend fixture service life in demanding industrial settings. The article explains how industrial lighting in hazardous and harsh environments must be carefully classified, designed and maintained using certified fixtures and rigorous standards to ensure safety, regulatory compliance, durability and long-term operational reliability. Lighting systems in industrial and hazardous environments are subject to a unique set of challenges that extend beyond providing general illumination. In industrial areas, areas with accessibility restrictions and in harsh environments, lighting must be more than functional — it must be safe, reliable, durable and maintainable. Improperly selected or poorly maintained lighting can become a safety hazard and may result in early equipment failure or noncompliance with regulations. This article is divided into three parts, each focusing on a fundamental aspect of industrial lighting in challenging environments: Classification of hazardous locations and explores the types of light fixtures suitable for these environments, with an emphasis on explosion protection and regulatory compliance. Design strategies for ensuring lighting systems can be maintained safely and efficiently, without disrupting operations or compromising worker safety. Critical standards and ratings used to select fixtures that can withstand extreme conditions, including ingress protection; material compatibility; and resistance to vibration, impact and temperature extremes.…
