What maximum temperature should not be exceeded by panels for light fixtures illuminating spray areas?

The maximum temperature that should not be exceeded by panels for light fixtures illuminating spray areas is 200 degrees F. This standard is critical in preventing ignition of flammable vapors or aerosols that may be present in such environments. In spray areas where flammable liquids are used, controlling the heat generated by lighting fixtures is essential to maintain safety.

Heat from light fixtures can ignite flammable materials, and exceeding the specified temperature can create a hazardous scenario. The limit of 200 degrees F is derived from safety standards that consider the types of materials typically found in hazardous locations and their respective flash points. By maintaining the temperature below this threshold, you significantly reduce the risk of fire or explosion in environments where vapors may accumulate.

The other temperature limits, while they may provide a certain level of safety, fall below established guidelines for environments classified as hazardous, which is why they are not the correct answer. Adhering to the 200 degrees F maximum ensures compliance with safety regulations and protects personnel and property within spray areas.
