Arc Flash Studies Across Southern California
Direct Source Industrial Solutions is headquartered in Santa Fe Springs, CA — at the center of Southern California's industrial corridor. We provide complete NFPA 70E arc flash studies for facilities throughout Los Angeles County, Orange County, and Riverside County.
Southern California's industrial base spans an enormous range of sectors and geographies: from the Los Angeles Basin's aerospace, food processing, and distribution operations, to Orange County's semiconductor fabs, medical device manufacturers, and defense contractors, to the Inland Empire's massive logistics and e-commerce fulfillment cluster and the Coachella Valley's agricultural, resort, and wind energy operations.
Every one of these facilities — anywhere with electrical equipment operating at 50V or above — is required under NFPA 70E and Cal/OSHA Title 8 to maintain a current arc flash risk assessment. Cal/OSHA actively inspects industrial facilities throughout SoCal, and penalties for non-compliance can exceed $25,000 per violation.

We handle field data collection, IEEE 1584 calculations, and label installation. Call (562) 396-9924.
What industries in Southern California require arc flash studies?
Any Southern California facility with electrical equipment operating at 50V or above requires an arc flash risk assessment under NFPA 70E and Cal/OSHA Title 8. This includes aerospace, semiconductor, food processing, distribution and logistics, healthcare, resort operations, water utilities, and manufacturing facilities across LA County, Orange County, and Riverside County.
What does an arc flash study include?

How often should Southern California facilities update their arc flash studies?
NFPA 70E recommends reviewing your arc flash study whenever significant changes are made to your electrical system, or at least every 5 years. Facilities with frequent equipment additions or utility service changes should review more often.
Is an arc flash study required by Cal/OSHA in California?
Yes. Cal/OSHA Title 8 requires California employers to assess electrical hazards including arc flash and provide appropriate PPE. NFPA 70E is the recognized standard. Non-compliance can result in penalties exceeding $25,000 per violation.
