Who sets the rules
for electrical testing
and safety?
Alphabet soup
There’s no question that electrical safety is a key concern
for electricians and engineers,
their employers, unions and the
government.
Every day, an average of
4,700 workers in the U.S. suffer
disabling injuries on the job.
Insurance industry estimates
put the direct cost of workplace
injuries in 2005 at more than
$8 billion.* With costs that high,
no wonder so many government
agencies and private groups hold
pieces of the safety puzzle.
To maximize safety for yourself and your team, you need a
solid understanding of the rules
and standards that govern safe
electrical work. This article will
help you cut through the alphabet soup of safety organization
names to see how each plays a
role in safety.
We’ll check them out in two
groups. First, we’ll look at the
government agencies that oversee workplace safety, such as
the U.S. Occupational Safety and
Health Administration (OSHA)
and the National Institute for
Occupational Safety and Health
(NIOSH).
Application Note
Then we’ll examine the
independent safety and standards organizations, including
the National Fire Protection
Association (NFPA), the American National Standards Institute
(ANSI), the Institute of Electrical and Electronics Engineers
(IEEE) and the International
Electro-Technical Commission
(IEC). Though they’re not part of
government, they too help set
the rules of the safety game.
The government agencies
First, where did OSHA and NIOSH
come from, and what do they
do?
Both agencies were created
by the federal Occupational
Safety and Health Act of 1970.
OSHA is in the U.S. Department
of Labor and is responsible
for developing and enforcing
workplace safety and health
regulations. In addition, many
states have their own occupational safety agencies that work
with OSHA and govern workplace safety on the state level.
NIOSH is an agency of the
U.S. Department of Health and
Human Services, established to
help assure safe and healthful
working conditions by providing
research, information, education,
and training in the field of occupational safety and health.

In other words, OSHA sets and
enforces the rules, while NIOSH
provides helpful information on
workplace safety. Here are some
examples:
Several OSHA regulations have
an impact on electrical workplace safety. For instance:
29 CFR (Code of Federal
•
Regulations) 1910 Subpart
I sets standards for Personal
Protective Equipment (PPE),
including eye and face protec-
tion, footwear and protection
for electrical workers, such
as insulating blankets, gloves
and sleeves.
The key electrical safety rules
•
are part of 29 CFR 1910
Subpart S, including design
safety standards for electrical
systems, safe work practices,
maintenance requirements
and safety requirements
for special equipment. This
regulation also covers training
requirements, sets guide-
lines for work on energized
parts, outlines lockout/tagout
procedures and provides rules
for use of PPE in electrical
work. The OSHA web site
provides other electrical safety
resources at http://www.
osha.gov/SLTC/.
While OSHA sets the broad safety
agenda, it leaves some details to
others. For example, the OSHA
electrical safety rules in 1910
Subpart S specifically refer the
reader to NFPA and ANSI codes
and standards for help in complying with OSHA. These include
NFPA 70E (Standard for Electrical
Safety in the Workplace), ANSI/
NFPA 70 (National Electrical
Code) and others. Subpart S was
updated in August 2007 and further amended in October 2008.
Here’s an example of how the
standards work together. OSHA’s
safety-related work practice
standards in Subpart S do not
currently address flame-resistant
(FR) clothing. However, OSHA
standard 29 CFR 1910.335 (a)
(2)(ii) requires use of protective
shields, protective barriers, or
insulating materials to protect
employees from shock, burns or
other electrically related injuries
while working near exposed
energized parts or where dangerous electric heating or arcing
might occur. Chapter 1 of NFPA
70E-2009 contains specific
requirements and methodology
for hazard assessment and selection of protective clothing and
other personal protective equipment. Employers may follow
NFPA 70E flash-hazard requirements as a way of meeting the
OSHA standard.
The key distinction is this:
OSHA 1910 Subpart S and other
OSHA safety and health standards are law. Failure to follow
these standards could result in a
citation, a work shutdown, fines
or other sanctions. The NFPA,
ANSI and other standards OSHA
refers to, on the other hand, are
intended as guidelines to safety.
“We’re pointing employers
and employees to these documents as sources for additional
information,” said David Wallis,
director of the OSHA office of
engineering safety. “For safe
work practices there are some
general-type requirements in
OSHA 1910 related to protection
from electric shock and electric arc hazard. Employers can
look toward NFPA 70E for more
specific information about the
kind of equipment they need to
protect their employees.”
“There is another caveat I
might explain,” Wallis continued.
“Sometimes OSHA will have a
specific requirement not contained in NFPA 70E, or where
the 70E provision might not be
quite as stringent. In that case,
OSHA would expect employers to comply with the OSHA
standard. Compliance with NFPA
70E would not automatically be
considered adequate.”
Key Points:
Both employers and employees are responsible
•
to know and follow OSHA standards.
Citations and penalties may be imposed if
•
standards are not observed.
Other safety standards, including NFPA 70E,
•
provide guidance on safety measures and
procedures. They do not supplant OSHA.
In case of conflict, follow OSHA standards.
