Arc Flash Solutions & 70e Compliance

Arc Flash is the sudden, unexpected release of intense heat, sound and light energy from electricity traveling through arcs, caused by either a phase to ground or phase to phase fault, which can cause fires, injuries and even death. Arc Flash contributing factors include:

•    Dropped tools
•    Accidental contact with electrical systems
•    Build up of conductive dust
•    Corrosion
•    Improper work procedures
•    Equipment Failure

Arc Flash Surveys are important as they comply with OSHA, NFPA, NEC, and ANSI regulations, increase equipment and system reliability, identify problem areas and develop effective solutions, and reduce design and operational costs. The National Fire Protection Association has issued OSHA-referenced standards and regulations requiring employers to provide the warning labels and protective equipment necessary to minimize risk of injury when employees are working on or in proximity to energized electrical equipment.  Terminal-Andrae has the knowledge and resources to perform the data-gathering survey, engineering software calculations and one-line diagrams required to achieve compliance with NFPA 70E. Terminal-Andrae provides many Arc Flash services such as single line diagram, hazard analysis/coordination study, labeling, and electrical preventative maintenance programs.

Single Line Diagram

NFPA 70E compliance requires up-to-date single line diagrams. This information is essential for documenting, troubleshooting and communicating information about your power systems. To meet this requirement, Terminal-Andrae conducts a comprehensive site survey used to update your existing single line diagrams or complete any unfinished electrical system drawings.

Hazard Analysis/Coordination Study

Terminal-Andrae uses state-of-the-art software to evaluate various electrical system configurations and operating modes. Arc Flash hazard analysis is essential for anyone working on or near proximity to energized electrical equipment. National Fire Protection Association (NFPA) states in their Standard 70E a "Flash hazard analysis shall be done before a person approaches any exposed electrical conductor or circuit part that has not been placed in an electrically safe work condition." To bring you into compliance with this standard, Terminal-Andrae offers Arc Flash Hazard Analysis to determine the appropriate Personal Protective Equipment (PPE) for anyone working near an exposed electrical conductor or circuit part. To help keep you in compliance, Terminal-Andrae Arc Flash Hazard Analysis also specifies the appropriate OSHA & ANSI Arc Flash Labels. Most important are the resulting safety benefits of a Flash Hazard Analysis helping prevent injuries, loss of property and expensive down-time.

Arc Flash Labeling                                                                                         
Arc Flash Labels identify potential arc flash hazards. Arc Flash Labels warn qualified individuals of the type of electrical hazard, correct Flash Protection Boundary distance, and the required Personal Protective Equipment (PPE). Labels must be clearly visible before examination, ad

justment, servicing, or maintenance of the electrical equipment.

Electrical Preventative Maintenance Program

Terminal-Andrae creates a schedule of service based upon the manufacturer’s recommendations and the environment to perform thermal scans and facilitate circuit breaker testing to identify potential problems at your facility. More information about our electrical preventative solutions can be found under electrical preventative maintenance.

Terminal-Andrae has the electrical knowledge, skills, and certifications to perform all your Arch Flash Fault Survey needs.
