About Chino
Arc Flash Studies for Chino, CA Industrial Facilities
Chino's industrial corridor spans the Riverside Drive and Kimball Avenue food processing zone housing major dairy and beverage producers; the Central Avenue logistics corridor with cold storage and distribution operations; and the Chino Valley Agricultural land-to-industrial transition zone where dairy operations increasingly coexist with modern warehousing. Food processing facilities in Chino run ammonia refrigeration systems, large compressor MCCs, and high-load processing electrical — environments where arc flash hazard analysis is complicated by both electrical complexity and ammonia classified locations requiring coordinated NFPA 70E / NEC 500 compliance.
Direct Source Industrial Solutions serves dairy processors, food manufacturers, cold storage operators, and logistics facilities in Chino and throughout San Bernardino County. We are based in Santa Fe Springs, CA — centrally located to serve the entire Southern California industrial market.

FAQ
Chino Arc Flash Study — Common Questions
Do you provide arc flash studies for dairy and food processing facilities in Chino, CA?
Yes. Direct Source Industrial Solutions provides NFPA 70E arc flash studies for dairy processors, food manufacturers, and cold chain operators in Chino, CA. We handle IEEE 1584 calculations and label installation for refrigeration and processing electrical environments. Call (562) 396-9924.
Do dairy operations and food processors in Chino need arc flash studies?
Yes. Any Chino food or dairy facility with electrical equipment at 50V or above requires arc flash risk assessment under NFPA 70E and Cal/OSHA Title 8. Refrigeration compressor MCCs, ammonia systems, and processing electrical present significant arc flash exposure — and Cal/OSHA actively inspects food processing operations in this corridor.
What does an arc flash study include?
A complete arc flash study from Direct Source includes: on-site field data collection, single-line diagram creation or update, short-circuit and protective device coordination analysis, IEEE 1584 incident energy calculations, arc flash boundary and PPE category determination, and NFPA 70E-compliant arc flash labels printed and physically installed on equipment.
How often does a Chino facility need to update its arc flash study?
NFPA 70E recommends reviewing your arc flash study whenever significant changes are made to your electrical system, or at least every 5 years. Chino facilities with frequent equipment additions or utility service changes should review more often.
Is an arc flash study required by Cal/OSHA?
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.
