Electrical safety in industry: from compliance to risk management

The greatest risks emerge throughout the asset lifecycle

Electrical installations are constantly evolving. New equipment is connected, switchgear is modified, and temporary solutions often become permanent operating conditions. Every change influences the overall behaviour of the electrical system.

When these modifications are not evaluated from a system-wide perspective, new risks can emerge, including inadequate protection coordination, increased fault currents, overloaded circuits, and altered fault characteristics. Because these changes typically occur gradually, they often remain undetected until a significant incident occurs.

Arc flash remains an underestimated hazard

One of the most significant risks within industrial electrical systems is the potential for an arc flash event. During an internal fault, enormous amounts of energy can be released within milliseconds, generating extreme temperatures, pressure waves, and high-velocity molten metal.

The severity of an arc flash incident depends not only on the electrical installation itself but also on factors such as protective device clearing times, network configuration, and the procedures followed during maintenance or operation.

Reducing this risk requires a combination of sound engineering design, appropriate protection philosophies, periodic system assessments, and disciplined safe working practices.

Effective risk management requires a systems approach

Electrical safety cannot be achieved through a single protective measure. It is the result of an integrated approach that combines engineering design, maintenance, inspection, operational procedures, and organizational governance.

An effective electrical risk management strategy typically includes:

• Periodic assessment of the technical condition of electrical assets.

• Evaluation of changes in system loading and network configuration.

• Regular review and coordination of protection settings.

• Short-circuit and arc flash hazard analyses.

• Clear procedures for working on or near energized electrical equipment.

• Continuous training and competency development for operational personnel.

When these elements are managed together, organizations establish an electrical safety program that extends well beyond minimum regulatory compliance.
