What is a potential hazard of using non-intrinsically safe lighting in explosive areas?

Using non-intrinsically safe lighting in explosive areas poses a significant hazard because such lighting can generate sparks or heat that may ignite flammable materials present in those environments. Intrinsically safe equipment is designed to operate in a manner that prevents the release of sufficient electrical or thermal energy to cause ignition. Non-intrinsically safe lighting lacks these safety features, meaning that it can create conditions conducive to ignition if the surrounding gases or dust are combustible.

The other options highlight benefits or characteristics unrelated to the hazard aspect: enhancing visibility and operating at lower voltage can be advantageous in some scenarios, but they do not address the risks posed by potential ignition sources. Moreover, stating that non-intrinsically safe lighting has no effects on explosive materials ignores the critical safety concerns associated with using equipment that can create an ignition source in hazardous environments.
