Written by NFPA at the request of OSHA to provide the prescriptive for compliance with Subpart S
Is the Electrical Safety Standard for employees who install, maintain or repair electrical systems and equipment
2015 Edition is the current edition & the next edition will be published in 2018
NFPA 70E® – Standard for Electrical Safety in the Workplace®
7
In several instances OSHA has been asked for a formal interpretation as to its relationship with the 70E Standard. The OSHA response is:
“Industry consensus standards, such as NFPA 70E, can be used by employers as guides to making the assessments and equipment selections required by the standard. Similarly, in OSHA enforcement actions, they can be used as evidence of whether the employer acted reasonably.”
OSHA tells you WHAT to do….NFPA 70E tells you HOW to do it

NFPA 70E 110.1 (I) Electrical Safety Auditing.
(1) Electrical Safety Program. The electrical safety program shall be audited to verify the
principles and procedures of the electrical safety program are in compliance with this standard.
The frequency of the audit shall not exceed 3 years. (2) Field Work. Field work shall be audited to verify the
requirements contained in the procedures of the electrical safety program are being followed.
(3) Documentation. The audit shall be documented.
Audits should cover all aspects of your safety program including electrical equipment.
Electrical Safety Audit
12
National Electrical Code
Updated Every 3 Years (current 2017 version)
For Electrical Safety…not design / efficiency
Equipment that is not installed or maintained properly can cause an electrical hazard.
When modifying old equipment, it must be brought up to new code. If you don’t touch old equipment, it is grandfathered in as compliant.
Equipment Installation & Maintenance
14
Maintenance OSHA & NFPA require that the equipment be maintained per
manufacturer guidelines….but this often gets ignored. Relay & Breaker Testing, cleaning off oil & dust…. Makes equipment more efficient / saves $$$ Resolves small problems before they become big ones.
GROUP QUESTION:
How often shall Ground Fault Interrupter Circuits be tested according to Manufacturer’s…and thereby by law?
Monthly ! Raise your hand if you are not compliant.
Equipment Installation & Maintenance
15
Electrical Workers should be referencing electrical drawings for design / safety.
Many companies file theirs away afterinitial build…good companies do the following:
Drawing Management Drawings are readily available to employees
Electrical Rooms ? Electronic Versions by Computer or Tablet ?
Employees are trained to read the drawings Drawings are updated at electrical equipment changes
Electrical Drawings
16
Arc Flash Most expensive part of electrical safety programs Most complex to understand Normally requires specialized engineer from outside
Short Circuit & Protective Coordination Studies Makes sure your equipment is
Properly rated to handle the electrical current Protective devices trip and in the right order
Normally done with arc flash study
Electrical Studies
17
NFPA 70E 110.3 Host and Contractor Employer’s Responsibilities
All parties have responsibilities. This section is divided into two parts, A and B:
(A) Host Employer Responsibilities(1) The host employer shall inform contract employers of: a. Known electrical hazards related to the contract
employer’s work that might not be recognized by the contract employer or its employees
b. Information about the employer’s installation that the contract employer needs to make the assessments required by Chapter 1
Contractors
18
(2) The host employer shall report observed contract-employer-related violations of this standard to the contract employer.
(B) Contract Employer Responsibilities.(1) To ensure that each employee is instructed in the hazards
communicated to the contract employer by the host employer. This instruction is in addition to the basic required training
(2) Ensure that each employee follows the work practices required by this standard and safety-related work rules required by the host employer
Contractors
19
(3) Must advise the host employer of: 1. Any unique hazards presented by contract employer’s
work 2. Hazards identified during the contract employer’s work
that the host employer did not mention, and 3. The measures taken to correct any violations reported to
him by the host employer; as required by previous paragraph
(D) Documentation. There shall be a documented meeting between the host employer and the contract employer.

Provides Guidelines and Specific Details One size doesn’t fit all – should be customized to your:
Equipment Tasks Performed Level of Hazards & Risks at the plant Skill Set of Employees & Risk Tolerance of Employer
Examples: What equipment can they work on…and when should they
call an electrical contractor? Do you have hazardous areas like battery rooms, dust,
gases…that need special consideration? Who is in charge of purchasing and managing the testing
of the PPE?Careful what you write !!! OSHA will measure you against your own policy, so don’t include things you aren’t going to do or you will be in violation !

An Arc Flash is an electrical explosion due to a fault condition or short circuit when either a phase to ground or phase to phase conductor is connected and current flows through the air.
Arc flashes cause electrical equipment to explode, resulting in an arc-plasma fireball.
• It strikes without warning
• The strike is lightning quick
The energy released by the arc is function of; • System Voltage• Magnitude of the current• Duration of the arc = time (big factor)
Arc Flash
26
TECHNICALLY…..NO, MAYBE and YES ! “How” you protect workers is left up to each employer, which is why
you won’t see “shall perform an arc flash analysis” in OSHA code. You have options….but they aren’t used very often.
Alternatives to Arc Flash Risk Assessments Use of robotics to do some electrical tasks
Limited to few applications & expensive Real time indicators on panels providing PPE requirements
Expensive NFPA 70E Tables
Requires electrical engineering calculations first…and if you are going to do this, it’s the same cost as doing an arc flash analysis
May be going away in next code cycle
Arc Flash: Law? Compliance?
27
TECHNICALLY…..NO, MAYBE and YES ! Identifying Electrical Hazards & the PPE to protect workers is
required, including from arc flash. OSHA letters of interpretation state that performing arc flash is one
way to protect workers OSHA fines companies if there is not a protective program in place for
protection against arc flash Arc Flash warning labels with protection information is required by
NEC as of 2017 version. All states have adopted NEC as their code, so this is a law as soon as your state adopts the 2017 version.
1910.269 – Power Generation electrical safety 2015 update now has specific language about conducting arc flash (incident energy analysis)
In short….you have options on how to comply, but arc flash analysis is what 99.9% of companies choose.
Arc Flash: Law? Compliance?
28
OSHA Enforces arc flash labeling
• Cives Steel Company Citation (Page 11) 7.6.12• Interstate Electrical Services 6.6.12• US Postal Service 7.12.10• O'Connell Electric Fines 11.16.09
Worker injury or death with no / wrong PPE or warnings
Negligence / Willful Violation If you know about a hazard and choose not to protect workers,
it may be negligent Business owners and managers are now being personally
responsible, which has resulted in fines and jail time.
Third Party Lawyers “Too expensive” is not a defense that will work Multi-million dollar lawsuits
Arc Flash - Ignoring…
29
It’s not been clear in writing until recently
NFPA 70E 130.5 (D) New in 2015The owner of the electrical equipment shall be responsible for the documentation, installation and maintenance of the field, marked labels. This includes the methods for calculating the data that is on the labels (conducting the arc flash analysis).
Arc Flash: Responsibility
30
Arc Flash Labels are required to have the following:
1. Nominal System Voltage
2. Arc Flash Boundary
3. At least one of the following Available Incident Energy and Corresponding working
distance, or arc flash PPE category from Table 130.7 (C)(15) (A), but not both
Minimum arc rating of clothing
Specific level of PPE
Does this label meet compliance ?
Arc Flash Labels
31
Wearing PPE ≠ Working Safe !PPE is the last line of defense in the Risk Control Hierarchy, not the first !
32
• Wearing the proper PPE is designed to limit the worker to 2nd degree burns or curable burns.
• PPE protects form Shock & Burn
• Workers can still get injured in an arc flash if wearing the proper PPE
• The air blast can throw workers, resulting in serious injury or death
• Greater than Category 4 has no PPE that will protect the worker from the blast.
Arc Flash PPE
34
Includes things like: Risk Assessment Job Briefings De-energization of equipment Lockout of equipment Testing for voltage Using Proper Tools Identifying & Setting up Boundaries Energized Work Permit
Should be documented in your written policy Requires training Part of Qualified Person annual observation

OSHA §1910.399 Subpart S and NFPA 70EQUALIFIED PERSON
“One who has received training in and has demonstrated skills and knowledge in the construction and operation of electric equipment and installations and the hazards involved.
Qualification is specific to Task & Equipment – not a title Person may be “Qualified” for one task or equipment, but not
the other. Person in training is a “Qualified Person” if working under the
direct supervision of another Qualified Person Annual Review & Documentation by another Qualified Person
Qualified Person
37
Only Qualified Persons May Work on Electrical Equipment >50 volts (unless already proven de-energized by another Qualified Person)
• Qualified Person:• Safety Training• Demonstration of Skills & Knowledge related to equipment &
tasks• At least annual review of Qualified Persons
• OSHA leaves it up to the employer to determine:• Program Requirements for “Qualified Persons”• How to determine & document “demonstration of skills &
knowledge”

Safety Training – Qualified Persons Employees must be trained:
Recognize & avoid specific hazards associated with electrical energy
Provide protection from the electrical hazards associated with their respective job or task assignments.
To identify and understand the relationship between electrical hazards and potential injury
Creating an electrically safe work environment Selection of proper tools & PPE Emergency Procedures / First Responder
Degree: Up to employer / based on risks & skill sets
Electrical Safety Training
42
Safety Training – Qualified Persons Frequency:
OSHA – up to employer & with equipment changes & deviations
NFPA 70E - 3 yrs & with equipment changes & deviations
Method: Live / classroom or on-the-job Online / Video….nope!
Many companies do not provide proper training
If the training does not include things like how to use meters to create a safe work environment or shock release methods…it is “awareness” training only and does not meet requirements.
Electrical Safety Training
43
Employees must have the skills of the operation of the equipment to perform their task safely
Proper training improves efficiency and downtime Common areas of Electrical Skills Training
• Reading Electrical Schematics• Basic Electricity• Electrical Troubleshooting• Motors & Motor Controls• PLCs• VFDs• Solar Maintenance• Standby Power & Generators• Grounding & Bonding

1. Identify Champion(s)2. Perform an Audit of Your Current Program3. Prioritize Fixing the Gaps by Hazard Risk Assessment4. Plan & Budget for Highest Priorities5. Develop a Written Electrical Safety Policy6. Develop a Qualified Person Program7. Perform Training to Standards, Your Program & Gaps8. Conduct Required Studies, Testing & Maintenance9. Periodic Audits on Program, Workers & Equipment
Implementation
50
1. IT’S HARD TO UNDERSTAND & COMPLY !! You can’t see it, smell it or hear it….it’s invisible ! Too much detail for Safety Managers to handle:
Must know electrical theory, equipment and installation NEC – 875 pages 70E – 104 pages 70B – 227 pages OSHA
Includes equipment choice, installation & maintenance 70E & NEC Codes Change every 3 years Equipment changing – Solar, PLCs, Robotics….
Solutions – You’re here – that’s the first step! Understand what you don’t understand and
fill in the gaps
Common Challenges
51
2. TIME CONSUMING & EXPENSIVE Some projects can take years if done internally, or months
with outsourcing Electrical systems frequently change….so it’s a never ending
process Arc Flash Risk Assessments & PPE can be expensive Getting equipment to code can be expensive
Solutions – Prioritize in small, manageable chunks. Create an annual budget. Mix internal implementation & outsourced to
maximize speed and $
Common Challenges
52
2. TIME CONSUMING & EXPENSIVE
Solutions – Sell in Safety If there is an accident, this will always be more than
the cost of investing in safety. Electrical Accidents are often very traumatic injuries /
deadly and require replacing expensive equipment. Down time – if you don’t have electrical…..
Common Challenges
53
3. LACK OF AN ELECTRICAL SAFETY CHAMPION Who’s driving the program?
MAINTENANCE ? SAFETY ? Who’s is keeping up with codes? Who’s do you go to answer questions? Who’s managing the PPE purchases?
Solutions – Identify a champion & provide proper tools & training
for success Outsourced electrical safety leadership – quarterly
meetings
Common Challenges
54
4. FEAR (and reality) OF INCOMPETENCE Employees afraid to ask for help / pretend they
know it all Many do have skill or knowledge gaps because
they only have on-the-job training Fear of reporting problems / being punished
Solutions – Encourage / Celebrate near miss reporting Create anonymous question box for maintenance Encourage continuing education programs for
electrical workers
Common Challenges
55
5. Overlooking NEC Compliance NEC is not for Electrical Design – but for Safety ! Electrical Safety Work Practices assume:
Equipment meets the scope of the application Equipment was properly installed Equipment was properly maintained
Safety Manager or Maintenance Manager often don’t have knowledge of NEC
Electrical Engineers often build for efficiency and cost, not safety, so it can get missed.
Common Challenges
56
5. Overlooking NEC ComplianceSolutions –
Assign NEC Champion to learn how to use the code
As part of work order completion / signoff, installed or modified equipment should be checked for approval by NEC Champion
Common Challenges
57
6. Program on Paper Only Written Policies that nobody knows exist Electrical Safety Labels – but don’t use them PPE – but not using them Generic Training - not specific to needs
Solutions – Assign a Champion Build an Electrical Safety Culture Train Workers on Requirements & Expectations Enforce the Policies & Requirements Periodic Inspections of Worker
Common Challenges
58
7. The “Old Guard” Passing along old methods & information Hasn’t been injured…so must be working safe? Reluctance to Change
Solutions – Assign a Champion Sell in change management to team Continued Education – new standards
