further discussion on the Peabody fatality. Recognized that everyone
needs to be aware of the possibility of creating a backfeed whenever
auxiliary power is utilized for maintenance purposes in an
electrical system. Safeguards need to be to be in place even if aux
power systems are not routinely used.
improvements in test equipment that make the current offerings much
safer than those available when many of us came into the electrical
industry. Even though there are still many of the older designs in
use and people need to be aware that the ratings are not adequate
for the circuit voltages being measured in today’s controls.
need to guard against becoming complacent about safety. Hearing the
same message repetitively can cause a person to develop a ‘Yah, Yah,
I’ve heard this before” attitude. Need to recognize that repeating
the message is one way to keep safety on everyone’s mind.

started out with Gary Sorenson talking about the changing weather
and safe winter driving. This also brought out the act of not
wearing seat belts it’s a basic PPE that many do not wear enough.
One in the group had lost several loved ones and friends who were
not wearing their seat belt when driving. Wearing a seatbelt some
of the time is not enough. Also if you are a first responder in
accidents knowing 1st aid can help keep some one alive till
paramedics can arrive.
told us about Australian electrical safety how every 6 months they
do a refresher in CPR and a “Hot save rescue” in Australia they have
bags in MCC and PCR’s that contain hot gloves and a hot stick with a
hook that can be used to pull someone out of an electrical circuit.
also discussed getting on the MSHA web site and reviewing the
winners of the sentinels
of safety awards and reviewing what they have done with their safe
practices to achieve their success.
Mike with Hampton noted
an incident at their warehouse were two of their people were trying
to access a ceiling mounted ballast by using a forklift to lift one
of them up to make the repair. This was halted by the operations
manager of the warehouse. This brought up that we all have the
power to stop unsafe acts when ever we come across them no matter if
we are at work or at home. It could save someone from injury or
brought up was lock out tag out and that the procedure is not
complete till you try the systems being disabled to know for sure it
is not live. Adam with North American talked about there zero energy
policy and that they work on nothing that is not at a zero energy
state. Rich Hall also stated that vendors are totally dependant on
the site personal to lock out for them so we need to be sure that it
gets done properly for our safety as well as others.
DCS is up
grading 30 year old shovels anything that can move dirt is being
utilized. They have developed an upgrade for a 295 shovel that can
be done in 7 days. It upgrades the PLC and the drive. Also DCS is
finding that they are upgrading machines for the second time
is coming out with a motor that has cooling channels in the motor
frame to help reduce heat. If you can run a motor 10 degrees cooler
than normal you can double the life of that motor. They have also
developed a medium voltage VFD for working outdoors it also
incorporates a much smaller foot print than older models. They also
have motor shaft power monitor, this monitors torque for faster
reaction time to over and under loads on the motor.
hold an electrical course for 2 days before the next meeting. If
anyone has anything they would like to see in the course please
contact Jim VanEmmerik.
Sorenson said that DCS would also like to hold a class in the future
for troubleshooting equipment. Hampton has developed a VFD
troubleshooting course. The class actually will have drives on site
for hands on experience.

talk to Rich.
