Sustainability, safety, and maintenance management are closely connected because the primary objective of maintenance is to ensure that equipment, machines, and facilities operate efficiently, safely, and with minimum environmental impact throughout their life cycle. Effective maintenance management not only prevents unexpected failures but also supports resource conservation, reduces waste, improves energy efficiency, and protects employees and the environment. A sustainable maintenance system balances economic performance, environmental responsibility, and social well-being while ensuring compliance with safety regulations and organizational objectives. Safety is one of the fundamental goals of maintenance management. Poorly maintained equipment may lead to accidents, injuries, fires, explosions, and environmental pollution. Planned maintenance activities reduce the probability of equipment failure and ensure that machines function within safe operating limits. Maintenance personnel must follow standard operating procedures, use personal protective equipment, perform risk assessments, and comply with occupational health and safety regulations. Safe maintenance practices reduce downtime, improve employee confidence, and minimize legal liabilities for organizations. Sustainability in maintenance management emphasizes extending the useful life of assets while minimizing the consumption of energy, water, spare parts, and other resources. Instead of replacing equipment frequently, organizations focus on preventive, predictive, and condition-based maintenance to maximize equipment reliability and reduce waste generation. Sustainable maintenance also supports the
