🔌 Electrical Safety is Now a Digital Issue!
Consider a maintenance team responding to an electrical fault during production. The equipment may seem familiar: breakers, motor control centers, relays... But what has changed is that these decisions now depend on digital systems that the maintenance team cannot fully control.
In connected facilities, automation and operational technology (OT) systems support every stage of the electrical safety lifecycle. Critical information such as device settings, audit logs, alarm histories, and remote access paths are stored in these systems. While these systems enhance safety when accurate and reliable, electrical safety is compromised when they are inaccessible or incorrect.
🚨 Why is Cybersecurity Becoming a Maintenance and Safety Issue?
The real concern here is not whether we can prevent a major cyberattack. The more urgent question is whether the systems, data, and access paths supporting maintenance and safety decisions are reliable. If breaker settings are changed without documentation, audit logs are missing, or remote access to critical systems is poorly managed, confidence in the organization's maintenance program can be undermined.
🔄 NFPA's Electrical Safety Cycle and Digitalization
The National Fire Protection Association's (NFPA) Electrical Safety Cycle provides an important framework for understanding this change. This cycle links NFPA 70, NFPA 70E, and NFPA 70B standards into a broad electrical safety model covering safe installation, safe work practices, and proper maintenance of electrical equipment. While these elements were once limited to physical equipment and written procedures, in modern facilities, each stage relies on connected automation and OT systems.
✅ Reliable Information is the Foundation of Safe Maintenance
Traditional electrical safety questions are still valid: Is the system installed correctly? Are employees protected from electrical hazards? Is the equipment maintained properly? However, the answers to these questions increasingly depend on digital information that must be accurate, protected, and accessible.
- Maintenance teams can use electronic audit logs to demonstrate job completion.
- Reliability teams can use condition monitoring data to prioritize equipment repairs.
- Engineers can rely on relay settings, single-line diagrams, and arc flash studies that should reflect current system conditions.
In every case, a digital dependency supports a maintenance or safety decision. Even if a breaker has been physically maintained, if its settings are changed without documentation, the facility's risk profile changes. Therefore, connected dependencies now require the same discipline applied to physical inspections, tests, and safety procedures.
🚀 Where Standards Are Heading: NFPA 70B and NFPA 72
NFPA 70B provides a structure for electrical maintenance programs. The 2026 edition states that an electrical maintenance program must work in conjunction with the relevant electrical safety program. This program includes elements such as equipment surveys, documented maintenance procedures, and inspection and testing plans. These program elements rely on reliable information.
The 2026 edition of NFPA 70B explicitly establishes the connection with cybersecurity. Electrical maintenance program elements include a risk assessment of OT cybersecurity where industrial control systems or OT are not limited to a local, non-networked connection. NFPA's supplementary material emphasizes that maintaining OT cybersecurity is an integral part of modern connected electrical, electronic, and communication systems.
NFPA 72 shows a similar direction for fire alarm and signaling systems. The 2022 edition added Chapter 11, which requires cybersecurity for fire alarm and signaling systems. This is important because many facilities do not consider fire alarm, signaling, or emergency communication systems as part of OT or automation, yet these systems increasingly rely on networked devices, software, and integrations with other facility systems.
🛡️ Security by Design: Its Place in Maintenance Planning
"Security by Design" principles help bring this issue to earlier stages. In industrial automation, Security by Design should influence how connected electrical, automation, and life safety systems are specified, integrated, accessed, maintained, and supported throughout their lifecycles. The Cybersecurity and Infrastructure Security Agency (CISA) defines Security by Design as an approach where products prioritize security as a core business requirement, not as a technical feature added later.
For a facility leader, the practical question is simple: Can this system be safely operated, protected, maintained, updated, monitored, and recovered?
