Arc Flash Protection
Protect your technicians, protect your company
59
years
Electrical shock, severe burns,
death—electrical technicians are
exposed to serious dangers when
working on or near exposed, energized
equipment. One of the most
serious risks, arc flash explosions,
causes hundreds of deaths and
thousands of disabling injuries in the
United States every year. As a result,
the Occupational Safety & Health
Administration (OSHA) has set
federal regulations to protect
employees from safety hazards
associated with potentially deadly, but
highly preventable, incidents. Failure
to use correct safety practices is a
clear violation of OSHA regulations.
Many companies, however, are not
compliant with OSHA regulations.
When companies don’t comply, they
run the risk of having an arc flash
explosion and suffering its related
expenses: lawsuits, fines, equipment
damage, facility downtime, and lost
productivity. More important, these
incidents can have devastating
physical, emotional, and financial
effects on victims and their families.
Is your company setting itself up for
a multi-million dollar lawsuit and
putting technicians’ lives at risk.
Jim Dutko, Monsen’s Director of
Engineering, says, “The vast majority
of the facilities that Monsen’s
technicians work in are non-
compliant. Not only are these
companies in violation of federal
regulations, they are putting human
lives in danger."
The good news is, understanding the
hazards helps you reduce your costs.
Simply put, investing in worker safety
reduces your risk of penalties.

Arc flash is an explosive release of
energy caused by an electrical arc due
to a conductor-to-ground or
conductor-to-conductor fault. During
an arc flash incident, thermal heat,
toxic fumes, and pressure waves are
released into the air. Blinding light
and intense sound waves accompany
these explosions. An individual does
not have to come into direct contact
with a live panel or conductor to
suffer a disabling injury from an arc
flash incident.
The temperature of an arc flash
explosion can reach more than
5,000°F. Arc flash’s powerful heat
spreads hot gases, causes radiation
burns, and vaporizes metal. The force
of the pressure waves alone can cause
hearing, eyesight, and brain damage;
blasts of pressure can also send
objects flying through the air.
