Arc Flash Risk Assessments & Arc Flash Studies
About Our Arc Flash Risk Assessment
Arc flash incidents can release extremely high levels of energy and pose serious safety risks for workers operating or maintaining electrical equipment. An Arc Flash Risk Assessment evaluates electrical distribution systems to identify potential hazards, calculate incident energy levels, and determine the appropriate protective measures needed to keep personnel safe.
Unity Design Group provides Arc Flash Risk Assessments and Arc Flash Studies for commercial and industrial facilities in Modesto and throughout Central California. Our experienced electrical engineers analyze your electrical system and provide the data, labeling, and documentation required to comply with NFPA 70E, IEEE 1584, and OSHA electrical safety standards.
What Is an Arc Flash Risk Assessment?
An arc flash is a dangerous electrical event that occurs when current flows through the air between conductors, creating an explosive release of energy. Arc flash studies evaluate the electrical system to determine the level of incident energy workers could be exposed to and identify the safety boundaries required to prevent injury.
Arc flash risk assessments help facility owners:
- Identify electrical hazards
- Determine proper PPE requirements
- Improve electrical system protection
- Reduce the risk of equipment damage
- Maintain compliance with safety regulations
Our Arc Flash Risk Assessment Process
Arc Flash Analysis
We evaluate electrical equipment and distribution systems to determine potential arc flash hazards and calculate incident energy levels at various points in the system.
Short Circuit Current Study
Short circuit studies determine the maximum fault current available in the electrical system and verify that equipment ratings are adequate for safe operation.
Protective Device Coordination Study
Coordination studies ensure circuit breakers, relays, and fuses operate properly during electrical faults to minimize system disruption and equipment damage.
Arc Flash Labeling
We provide ANSI-compliant NFPA 70E arc flash hazard labels for electrical equipment, helping workers quickly identify potential hazards and required PPE.
Electrical System Data Collection
Our engineers coordinate with facility personnel and utility providers to gather accurate system data for modeling and analysis.
When Should Arc Flash Studies Be Performed?
Arc flash risk assessments should typically be updated:
- At least every five years
- After major electrical system upgrades
- When equipment or protection devices are modified
- When facility expansions change electrical load conditions
Regular updates ensure the electrical safety study accurately reflects the current system configuration and hazards.
