The environmental condition of Niger Delta is harsh with average humidity of about 85 percent (relative), and rainfall of about 2500mm. Some of the factors may affect the machine directly or indirectly. It is necessary to take a critical study to identify the effect of humidity so that proper selection could be made for safe operation and for longer life of the equipment.From the results, humidity was the most severe environmental factor that affect the machine. It was also seen that a motor stored in that environment for a year looses 15 percent of its life span due to humidity The humid effect is more severe in the rainy season therefore proper selection of machine and frequent check and drying is necessary to keep a longer life of the machine.
