Survey Says:
Raise Arc-Flash Awareness

ACCORDING TO A recent global arc-flash survey conducted by Littelfuse Inc., Chicago,
(littelfuse.com), there's a real need to raise electrical-safety awareness in industry. Despite the fact
that most of the 255 people surveyed (all of whom play some role in a site's electrical safety) felt
arc-flash mitigation was a priority in their workplaces, only 66% of facilities had completed an
arc-flash risk assessment.
As Littelfuse's report on the survey explains, arc-flash risk assessments determine the incident
energy that employees risk being exposed to when they're near electrical equipment. Thus, facilities that operate without regular shock and arc-flash risk assessments are like drivers rolling down
a highway with their eyes closed: They're cruising along blind to the risk their employees face.

AMONG SPECIFIC SURVEY
FINDINGS:

 One in three survey respondents said they had
experienced an arc-flash incident.
 Nearly 25% of respondents said they had never received safety training in their workplace.
 Of the facilities that had completed an arcflash assessment, 77% have equipment at
high risk-rated more than 8 calories/cm2.
The calorie rating determines the required
minimum arc-flash protection clothing
workers must wear to protect themselves. (To
put this finding in perspective, Littelfuse notes
that onset of second-degree burns may occur
at 1.2 calories/cm2.)
 While 85% of respondents are familiar with
the National Fire Protection Association
(NFPA) 70E, Standard for Electrical Safety in
the Workplace, only 40% are familiar with the
2018 edition of the NFPA 70E Hierarchy of
Controls (right).

HIERARCHY OF CONTROLS








The Littelfuse arc-flash-safety-survey report
points out that the hierarchy of controls starts
with the most-effective method and moves
to the least-effective safety measure. Not all
hazards can be eliminated, but the idea is that
the closer you get to the top, the safer workers
will be. The hierarchy-of-controls methods
include:
Elimination-Physically remove the hazard.
Substitution-Replace the hazard.
Engineering controls-Isolate people from
the hazard.
Awareness-Inform people of possible
hazards.
Administrative controls-Change the way
people work.
Personal protective equipment (PPE)-
Protect the worker with PPE.
NFPA 70E follows the model of the
hierarchy of controls. The standard establishes
the de-energization of energy sources as the
preferred approach to working on or around
electrical hazards, and emphasizes that PPE
should solely be relied upon as a last resort
(or an extra layer of protection). PPE is not the
first line of defense, it is the last.
