As I was ﬁlling up my car with gas, I
began taking pictures of the signage and
messages on the pump with my phone. As
I began to look a them closer, I realized
there was a lot to see on a gas pump, some
of which ties to Lean. I have attempted to
label and describe what I saw and draw a
few lessons. Take a look and enjoy. I
would be pleased to learn of applications
you see that I have missed.

Visual Guide to a Gas Pump
Lean Lessons of the Pump
• Too much signage can reduce its
• Visual Standard Work is a good way to
get a message across
• Colors can be used for Visual Effect

• We can use tools in combination to
• There are Lean aspects around us if we
will look for them
• 1, 8, 12, 13, & 23-Safety Guidelines/
Warnings-We would expect such to be
posted based on regulatory
requirements. I was surprised by how
many there were.
• 2, 4, & 19-Measurement Displays-
Theses tell us how much. They
become more important if we are
limited by budget or ﬁlling capacity
(think 2 gallon small can).
• 3-Inspection Label-This does a couple
of things: one, records the last time
the Government inspected the
accuracy of the Pump, and two, serves
as a visual that it has been inspected.
I like that it allows late differentiation.
The month of the inspection punched
so the same labels can be used for a

• 6-Call Button-Allows user to ask for
help or report an issue. Visual green

visually coded buttons using green,
red, blue, and gray. Grade selection is
yellow to stand out verses the black.
• 11 & 16-Visual Standard Work-11
Shows how to work the pump. It is
large and easy to follow. It helps to
make sure that someone new to this
style pump can use it without issue.
16 Shows how to swipe a card in the
card reader. Both are good examples
of simple and effect standard work.
