Brief Electrical Safety History of:

OSHA/PERRP

National Electrical Code (NEC)

NFPA 70E Standard

5

In 1896, 23 people started the development of the first national electrical

installation rules in the United States, the National Electrical Code (NEC).

This was only 7 years after electricity became commercially available.

Thomas Alva Edison established the Edison Electric Illuminating Company

of New York. On 4 September 1882, Edison’s direct current (dc) generating

station at 257 Pearl Street. This installation was the forerunner of all central

electric generating stations.

In 1895 - Five Electrical Codes existed with no consensus standard.

• 1970 - Federal OSHA created

(Public employees exempted from coverage)

• 1992 - Ohio Public Employment Risk Reduction began

• 1994 - Ohio Public Employment Risk Reduction went into full effect

• 2005 - PERRP became part of the Ohio Bureau of Workers’

Compensation, Division of Safety and Hygiene

• At OSHA’s request in1976, the standards council of the NFPA appointed

a committee to develop employee electrical safety standards, NFPA 70E.

7

• A new standard for Electrical Safety was first published in 1979: NFPA

70E edition #1.

• The NFPA 70E Electrical Safety Standard has been updated in 1981,

1983, 1986, 1995, 2000, 2004, 2009, 2012, 2015.

• In 2013 October 23, 2013 – The National Fire Protection Association

(NFPA) announced the new Certified Electrical Safety Compliance

Professional (CESCP) certification program, created to encourage

education on electrical safety within the industry, based on NFPA-70E

OSHA vs. ANSI

OSHA is responsible for promulgating and

enforcing mandatory safety and health standards

(regulations).

ANSI is the American National Standards

Institute; a private, non-profit organization.

ANSI promotes and facilitates voluntary

consensus standards and safeguards their

integrity.

Conducting a Facility Inspection

13

Why use ANSI or

Other Standards?

ANSI standards are developed as a “consensus” of “best” practices in industry.

Therefore, industry consensus standards may be evidence that a hazard is "recognized" and that there is a “feasible” means of correcting a hazard.

So…Employers are encouraged to use consensus standards in their efforts to comply with regulations that do not have specific requirements for hazard correction.

At no time…can an ANSI or other consensus standard be used for compliance if it is in direct conflict with an adopted regulation unless it provides equivalent or greater protection!

110.3 Host and Contract Employers’ Responsibilities.

(C) Documentation. Where the host employer

has knowledge of hazards covered by this

standard that are related to the contract

employer’s work, there shall be a

documented meeting between the host

employer and the contract employer.

110.3 Host and Contract Employers’ Responsibilities.

(B) Contract Employer Responsibilities.

The contract employer shall advise the host employer of

the following:

(1) Any unique hazards presented by the contract employer’s

work

(2) Hazards identified during the course of work by the

contract employer that were not communicated by the

host employer

(3) The measures the contractor took to correct any violations

reported by the host employer under 110.3(A)(2)

and to prevent such violation from recurring in the

future

Clarification of Multi-employer citation policy:

Scope: OSHA-wide

References: OSHA Instruction CPL 2.103 (the FIRM)

Suspensions: Chapter III, Paragraph C. 6. of the FIRM is

suspended and replaced by this directive

CPL 2-0.124

On multi-employer worksites (in all industry sectors), more than one

employer may be citable for a hazardous condition that violates an OSHA

standard. A two-step process must be followed in determining whether

more than one employer is to be cited.

Flash Hazard Analysis

Methods

51

Flash Hazard Analysis

There are several methods to conduct an arc flash analysis:

– Use NFPA 70E Tables

Tables have limitations (Note sections)

Tables make several assumptions

Best used as a temporary solution

– Use NFPA 70E Equations (Lee Method)

Simple, can be done by hand using a calculator

– Use IEEE 1584 Equations

Most accurate method, but very complicated

– Purchase a software program (SKM, ETAP, EasyPower, to name a few)

Expensive, but easy to use

– Contract someone else to do it

Probably the best solution for smaller companies

52

ARTICLE 130



An arc flash risk assessment shall be performed and shall:

(1) Determine if an arc flash hazard exists. If an arc flash

hazard exists, the risk assessment shall determine:

a. Appropriate safety-related work practices

b. The arc flash boundary

c. The PPE to be used within the arc flash

boundary

53

ARTICLE 130


130.1 General. Article 130 covers the following:

(1) When an electrically safe work condition must be established

(2) The electrical safety-related work practices when an
