Better at identifying when repairs are genuinely necessary, predictive maintenance outperforms preventative methods in seeing the earliest signs of impending failure.
Preventive maintenance aims to identify and correct potential issues before they become critical. Most often, this is done through scheduled inspections that occur throughout the year.
Injury or death can result from the unexpected or inadvertent activation of electrical equipment. The power must be cut at the switch box, and the breaker tagged out or padlocked in the off position before any inspections or repairs may be conducted.
