What exposures should be limited where conductors or equipment are located?

Limiting exposures to gases, fumes, vapors, liquids, dust and dirt, humidity levels, and temperature extremes is crucial for maintaining the safety and longevity of conductors and electrical equipment. Each of these factors can significantly impact the performance and integrity of electrical installations.

Gases, fumes, and vapors can create corrosive environments that may degrade the insulation and components of electrical conductors, leading to increased risks of failure and short circuits. Exposure to liquids can result in electrical shorts and hazards associated with electrocution, making it imperative to keep areas around electrical equipment dry and free from spilling substances.

Dust and dirt accumulation can obstruct ventilation pathways, trap heat in equipment, and create pathways for creep currents, which could lead to malfunctions over time. Humidity levels can lead to condensation that creates moisture-related issues. High humidity can increase the risk of corrosion and reduce the effectiveness of insulation properties over time.

Temperature extremes can affect the performance of conductors and equipment by causing them to expand and contract, potentially leading to mechanical failure or thermal overload. Equipment is often rated for specific temperature ranges, and operating outside of those ranges can lead to unsafe conditions.

In summary, by recognizing that all of these exposures—gases, fumes, vapors,
