OVERVIEW
Be Safe and Compliant
Arc flash is a serious hazard with
potentially devastating eects.
Ensuring worker safety and meeting
the challenges of the new arc flash
safety requirements can be a
diicult task.
Trust Vertiv's Electrical Reliability
Services (ERS) to deliver the most
complete solutions for arc flash
compliance. From risk assessment
and labeling to personal protective
equipment (PPE) and training, ERS will
provide you with the industry's best
safety programs, while reducing
your risk and ensuring
regulatory compliance.
Whether you require a complete
program or short-term assistance
with arc flash calculations, ERS has
a solution to fit your needs.

Electrical Reliability Services
Ensure worker safety and regulatory compliance with
comprehensive arc flash solutions
Electrical hazards, specifically shock, arc
flash and arc blast, can result in serious
injury or death to electrical workers.
Ensuring safety and meeting regulatory
requirements can be diicult to
accomplish in-house without the
assistance of resources familiar with
industry standards and recommended
practices. Consider the benefits of
partnering with ERS to help develop and
implement a complete, cost-eective,
single-point arc flash solution.
Our comprehensive portfolio of arc flash
solutions includes:
y Risk assessment
y Site review / compliance assessment
y Protective scheme design review
y Short circuit and coordination studies
y Single-line diagrams
y Arc flash analysis
y Hazard labeling plan
y Electrical safety program
review / development
y Training and performance evaluation
y PPE plan
y Preventive maintenance
y Documentation
y Optional annual re-certification
Risk Assessment
The National Fire Protection Association's
Standard for Electrical Safety in the
Workplace® (NFPA 70E) requires facility
owners to perform an arc flash risk
assessment prior to allowing a worker to
perform a task on or near energized
equipment. The risk assessment identifies
the presence and location of potential
hazards and provides recommendations
on PPE, boundaries for limited and
restricted approaches, flash protection,
shock protection and safe work practices.
To calculate the incident energy, all
technical data such as equipment type,
voltage, ratings, impedance, etc., is
collected and reviewed.
An eective way to conduct an
assessment is to utilize an outside
contractor trained in this procedure.
The technical sta of ERS is qualified
according to the National Electrical Code
definition. Our qualified electrical workers
have undergone specific training in the
hazards of working on energized
equipment, and the use and proper
application of PPE.

ARC FLASH SOLUTIONS
To provide accurate results, state-of-the-art software (e.g., SKM, ETAP®, EasyPower®) is
utilized to perform arc flash calculations in accordance with the standards of NFPA and
the Institute of Electrical and Electronics Engineers (IEEE). These software packages
enable users to evaluate alternatives quickly and easily in order to establish optimal
protective schemes and device settings.
Hazard Labeling Plan
NFPA 70E mandates that electrical equipment such as switchboards, panelboards,
industrial control panels, and motor control centers, that are likely to require
maintenance while energized, must be field marked with a label. ERS can assist with
compliance during each phase of an arc flash risk assessment. Once the initial
assessment has been performed, ERS supplies the labels and can assist in applying the
appropriate hazard warning labels. As part of an ongoing labeling plan, updated labels
can be provided to accommodate equipment or system changes, or regulatory updates.
Site Review /
Compliance Assessment
The Occupational Safety and Health
Administration (OSHA) can and does
enforce its requirements. To ensure
compliance, ERS will determine the steps
needed to meet OSHA and NFPA
requirements. By conducting a
comprehensive assessment to identify
areas of risk and non-compliance, we will
formulate a plan to bring your facility into
compliance in the most eicient
way possible.
Protective Scheme Design Review
ERS’s technical sta can conduct a
protective scheme design review and
operational assessment of your electrical
distribution system to identify areas for
reducing potential arc flash hazards.
Several areas are evaluated including fault
current levels, arc exposure times,
operational procedures (such as remote
breaker control and remote racking), and
system grounding. Conducting a design
review is the most eective way to uncover
potential hazards, so options can be
evaluated and mitigation strategies can
be employed.
