Arc Flash Hazard Assessment & ETAP Power System Study Malaysia
Saturn Pyro provides Arc Flash Hazard Assessment and ETAP Power System Study services for industrial, commercial and utility electrical installations throughout Malaysia.
The study helps identify arc flash risk, calculate incident energy, review protection settings, update electrical single line diagrams, define boundaries, prepare warning labels and support safer electrical work practices.
Arc flash is a dangerous electrical fault that releases high levels of thermal energy. It can cause serious injury, equipment damage, fire and production downtime.
The risk is present in many electrical installations, especially where high fault levels, incorrect protection settings or exposed electrical work are involved.
Arc flash risk cannot be fully removed, but it can be assessed, labelled and reduced through proper power system study, protection coordination, safe work procedures, PPE selection and training.
The Key Message: Do Not Guess the Risk
Arc flash hazard level depends on available fault current, protection clearing time, working distance and equipment configuration. These must be calculated from actual electrical system data.

Why ETAP Power System Study Is Important
ETAP allows the electrical system to be modelled as a digital representation of the facility. This enables simulation of normal operating conditions and fault conditions without interrupting production.
Digital Electrical ModelCreates a structured engineering model of the actual electrical network.
Fault and Protection BehaviourValidates short-circuit levels, protection device behaviour and clearing time.
Safety Decision SupportProvides a stronger basis for PPE, labels, boundaries and electrical safety decisions.

Site escort and safe access
In most cases, data collection is visual and non-intrusive. A shutdown is normally not required unless specific testing or inaccessible equipment verification is requested separately.
Arc Flash Warning Labels
Arc flash labels provide important safety information at the equipment location. A typical label may include equipment name, voltage, incident energy, arc flash boundary, working distance, PPE requirement and shock approach boundary information.

Standards and References
Arc flash assessment is commonly aligned with recognised electrical safety and calculation references such as NFPA 70E, IEEE 1584 and workplace electrical safety requirements.
