What is a key consideration for lighting in hazardous locations?

• A. It must be bright enough for visibility.
• B. It must be rated for the specific class and division.
• C. It can be any commercially available light.
• D. It should be aesthetically pleasing.

Answer: (B)

In hazardous locations, the selection of lighting is critical to ensure safety and compliance with safety regulations. One of the most vital considerations is that the lighting must be rated for the specific class and division of the hazardous area. This rating is designed to prevent ignition of flammable gases, vapors, dusts, or fibers that may be present in the environment. For example, areas classified as Class I, Divisions 1 or 2 have different requirements than Class II, which pertains to locations with combustible dust. Using lighting fixtures that are not appropriately rated can lead to catastrophic failures, such as explosions or fires, if electrical sparks ignite hazardous materials present in the locality. Therefore, it is crucial to adhere to these rigorous standards to ensure that all lighting used in hazardous areas is designed to withstand the unique environmental challenges posed by these locations, thereby safeguarding personnel and property.
