tance measurements and then entering
the data into the CMMS. The Electrical
Maintenance Program includes visual
inspections and thermal imaging. The
program was applied to all critical
electrical-distribution systems, as well
as critical equipment used to support
manufacturing. Many issues have been
discovered and resolved solely because
of this program, he stated.
Around the same time, the Facilities
Engineering team worked together to
set up a vibration-analysis program.
The program has also created significant improvements in the department's
ability to provide uninterrupted
utilities to manufacturing, identifying
motor issues, and making repairs
before a catastrophic failure happens. It
also helps identify equipment that may
need precision alignment to improve
efficiency and increase reliability.
Electrical readings are taken
for panels and motors, including
high-voltage readings. "One thing
we look for is voltage unbalance,"
Myers said. "The industry standard
is 3% unbalance. This is significant
enough to cause additional heat and
reduce the life of a motor. We track
these readings. If unbalance is found,
further investigation is performed to
determine the root cause."
Myers' involvement in electrical reliability doesn't end there. He also works
with the company's Electrical Steering
Committee. The goal of the committee
is to ensure that procedures are in
place to maintain electrical safety, such
as ensuring an arc-flash analysis is
completed and posted at the equipment, reviewing energized electrical
work permits, and drafting or revising
any electrical-related SOPs. 
"Several years ago it was evident
that there was a need to better manage
electrical safety," Myers said. "At AstraZeneca, we regularly evaluate electrical
safety and constantly make an effort
to update how we manage it. So the

current Safety Health and Environment (SHE) director created the team
and asked me to be a member. Shortly
after that, I took on a very large task,
to build a custom electrical test board
and design a test that all technicians
that work on electric equipment in
their departments would have to take."
This test was designed to comply
with NFPA 70E regulations and
determine if an employee is electrically
qualified. As a result, the site has had
no electrical injuries. 
Myers also serves on the Electrical
Improvements Team, which was
formed to reduce any impact on
manufacturing caused by the electrical
system. An example of one effort was
a project to ensure the panel schedules
match the field tags, and that when the
breaker is turned off it actually goes to
the appropriate equipment. 
"You would be surprised how
many discrepancies are found during
this process," he said. "The team also
looks to increase its robustness and
reliability by ensuring electrical feeds
come from different switchgears when
it makes sense. A couple of examples
would be that we have many environmental chambers that house product
and samples of product. They are very
critical to the site. Some of the critical
units have two feeds-a primary and a
secondary. It was discovered that both
feeds came from the same panel. This
was identified as an issue because electrical maintenance is performed
on switchgears every three to five
years. When the switchgear would
have been de-energized for maintenance, power to the chambers would
have been lost, potentially putting all
that product at risk."
To resolve the issue, a plan was engineered to change the secondary
feed to a panel from a different
switchgear. This solved the problem
and has provided redundancy for the
system. The team has experienced
issues where redundant feeds were not
an option to the equipment. "We found
this on our freezer that houses very
critical contents," he explained. "To
resolve this issue, I came up with a
plan to install an ATS (automatic
