What is NFPA 70E?
 Standard for Electrical Safety in the Workplace
 Covers industrial personnel
 Electricians
 Maintenance workers
 Anyone who works on or near energized parts
 Chapter 1- covers Safety Related Work Practices
 Chapter 2- covers Safety Related Maintenance
Requirements
 Chapter 3- covers Safety Requirements for Special
Equipment
 Annexes provide additional and important
information

What is an Arc Flash?
P A G E
6
A dangerous release of energy created by an electrical
fault
Release will contain:
 Thermal energy
 Acoustical energy
 Pressure wave
Debris Variables that effect the size and energy of an
electric arc flash are:
 Amperage
 Voltage
 Arc Gap
 Closure time
 Distance away from arc
 3 phase vs. single phase
 Confined space

Typical equipment that can cause an arc include:

Motor Control Centers (MCC’s)
Circuit Breakers

Metering Devices (remove – install)
Panel Boards
Switchgear (low and high voltage)

Why is FR Clothing needed?

Costs of an arc flash
 30,000 arcs, 7,000 burn injuries per year
 Over 2,000 people admitted to burn centers
yearly with severe arc flash burns
.
 Burn treatment requires approx. 1.5 days
hospitalization per % burn
 Average hospitalization is 19 days, at costs
exceeding $18,000/day - many over
$1,000,000

Burns
 Most severe burn injuries and fatalities are caused by
non-flame resistant clothing igniting and continuing to
burn
 Flame resistant clothing will self-extinguish,
thus limiting the injury
 Body area under non-FR clothing is often burned
more severely than exposed skin
What is a burn?
A chemical process which progressively injures skin; severity
relates to depth
1st : redness, pain – not permanent
2nd: blistering – skin will regenerate
3rd: total skin depth destroyed. Will not regenerate –
requires grafting
4th : Underlying muscle damaged

Survival
Three factors: extent, severity, location
-Extent expressed as % body surface reaching
2nd and 3rd degree.
-Closely linked to survivability
-Severity, location linked to quality of life

Cost of an Arc Flash Injury
Burn treatment requires approx. 1.5 days hospitalization per %
burn
Average hospitalization is 19 days, at costs exceeding $18,000/day
Total hospitalization cost typically ranges from $200,000 to
$750,000, with many over $1,000,000

NFPA 70E – 130.7 (13) (a) (d)
Care and Maintenance of FR Clothing and FR Arc Flash Suits
 (a) Inspection. FR apparel shall be inspected before each
use…Protective items that become contaminated with
grease, oil, or flammable liquids or combustible materials
shall not be used. Care and Maintenance of FR Clothing
and FR Arc Flash Suits
 (d) Cleaning, Repairing and Affixing Items. When FR
clothing is cleaned, manufacturer’s instructions shall be
followed to avoid loss of protection… the same FR
materials used to manufacture the FR clothing to provide
repairs…guidance in ASTM F 1506.
P A G E

1.2.2- …For best cleaning results and proper maintenance of the
protective characteristics of flame, thermal, and arc resistant
clothing the services of a professional processor is
recommended. (See X1.1.)
X1.1 …In addition, the end user must ensure the cleaning
process used in home laundering follow the manufacturers
recommended laundering procedures…for example, if
chlorine bleach is used in home laundering, the flame,
thermal, and arc resistant characteristics of some types of FR
clothing can be compromised or eliminated…
NOTE X1.1—Some soils containing potentially flammable
materials such as solvents, oil, and other petroleum
products may not be removed by home laundering…
