What safety feature is commonly required for luminaires in industrial applications?

In industrial applications, luminaires are often subjected to harsh environments where they may be exposed to dust, debris, chemicals, or physical impact. The use of protective covers or guards is essential as it helps safeguard the fixtures from damage and ensures the safety of personnel working in the area. These protective measures can also prevent injuries that might result from broken glass or exposed electrical components if a luminaire were to fail or break.

The requirement for protective covers or guards aligns with safety codes and best practices in industrial settings, emphasizing the need for robust lighting solutions that enhance safety and durability. This feature not only extends the lifespan of the luminaires but also contributes to maintaining a safe working environment. Other options, while beneficial in certain contexts, do not specifically address the fundamental need for physical protection in industrial luminaires.
