Lean
and clean
In
trying to become a 5-S plant, don't forget about a sixth S: sorbents.

Lean manufacturing. Kaizen. 5-S.
These are important concepts, all
geared toward making your plant more efficient and productive, and
helping workers be happier and more satisfied in their work.
That might seem like a tall order,
but when it comes to implementing a 5-S program in your workplace, it
isn’t necessarily the big things that have to be changed. In many
ways, it’s the smaller, day-to-day, detail-oriented things, the ones
that get taken for granted.
Something as simple as a solid
sorbent program can fit into your 5-S process. Or, looked at another
way, your 5-S process can help you develop a solid sorbent program.
Let’s review the steps and see how
sorbents come into play.
The 5-S’s are seori, seiton, seiso,
seiketsu and shitsuke.
SEORI (Sort): The first S focuses on
eliminating unnecessary items from the workplace. What do you think of
when you apply that to sorbents? Well, how many different sorbent
products do you use? Do you really need all those SKUs? And, are you
using the right sorbents?
Through environmental and site
surveys, especially at larger plants where a bunch of departments buy
what they want from whoever they want, representatives from sorbent
manufacturers often find that they can help plants reduce the SKUs
they need by as much as 50 percent.
So, by looking into what product(s)
you use for a given application, and keeping an eye open to SKU
rationalization, you can expect significant savings through
simplicity. Fewer SKUs turn faster and take up less space in storage.
That is exactly what this first S is all about. You don’t
necessarily need a myriad of different sorbents. You just need the
right sorbent.
SEITON (Set in order): This is about
getting organized, determining everything you need to do the job, the
quantities you need, and their present or proper location.
In regard to sorbents, this is more
important than you may have originally thought.
Chances are that your plant is at one
extreme of a sorbent spectrum. At one end, no one is totally certain
where the sorbents are kept on the shop floor or where to find them
when the need arises. At the other end, the sorbents are under lock
and key in the tool crib. “If they need some, they’ll have to come
get it.” Clearly, there’s a better way.
This might seem obvious, and it’s
just as true for emergency response as it is for the routine
maintenance use of sorbents, but you should have a place assigned for
sorbent storage. Call it a “Sorbent Station.” After
all, sorbents must be accessible to the people who need them, when
they need them.
That’s why some sorbent companies
package products in boxes, and why they try to make their sorbents
convenient to use and store (for example, using dispenser boxes, or
offering a choice between mobile and stationary spill kits). Some
products even come with a collection station for immediate disposal of
used sorbent pads.
SEISO (Shine): This refers to keeping
the work area clean and neat to help sustain productivity and pride.
Sorbents fit here.
It’s well documented that good
housekeeping is a key factor in maintaining high levels of safety and
productivity. It doesn’t take much imagination to understand why a
properly outfitted workstation (one with sorbent pads, rolls, socks
and rugs) is a cleaner, safer and more productive workplace than one
with wet, oily, slippery floors, or one where workers are ankle deep
in kitty litter.
That’s a “before and after”
picture that needs no further explanation.
SEIKETSU (Standardize): This focuses
on standardizing best practices. Establishing a good sorbent program
is imperative. Sorbent companies can help you out here with
environmental and site surveys.
In terms of emergency response and
preparedness, you must have a contingency plan in place for
“worst-case discharge.” This should include knowing what liquids
are at risk, their hazard level, the areas in need of protection, how
to best contain a spill, which sorbents to employ, and who to call for
outside help in hazardous materials cleanup.
Best practices for routine
maintenance sorbent usage involves understanding the applications,
preparing the workplace for the job at hand and having the right
sorbent materials available.
For example, prior to a plant
shutdown, you must know what machines are scheduled for work and what
liquids will be cleaned up. When reviewing your material handling
areas, you must recognize that leaking forklifts are a common
occurrence and prepare the storage area with a sorbent industrial rug
or barrier spill mat suitable for vehicle storage. The same process
applies to liquid storage areas, laboratories, workstations, aisles
and walkways, and literally all other plant areas.
SHITSUKE (Sustain): The final S is
all about sustainability, or making the change part of the way you do
business from now on. This is often the toughest part of a 5-S
program.
Even after you spend all that time
and energy getting organized, it’s easy to slip back into old,
sloppy habits. It’s human nature.
The good news is that a sorbent
program is very easy to maintain. Using sorbents is as intuitive and
straightforward as using a sponge and paper towels in the kitchen.
Just keep a mental picture, or
perhaps an actual photo, of what it was like before: wet, oily,
slippery floors; parts and equipment covered and dripping with oils,
grease, coolants, etc.; and workers standing ankle deep in kitty
litter.
You and your co-workers could go back
to working in such a pigsty, but why would you?
In pursuing 5-S, remember to add a
sixth S for sorbents!

Sorbent
selection guide
To choose the right absorbent product for the application . . .
1)
Know what liquids you need to pick up and whether that liquid is
considered hazardous. This will point to whether you need an
oil-only, universal or chemical sorbent.
2)
Know how much liquid you need to clean up, how often you need to
replace it and if it’s a constant leak, drip or spray as
compared to a periodic “spill.” This will help you select a
required absorbent capacity (heavy, medium or light duty)
3)
Know where and how you will use your sorbents. Are you going to
wipe things down with it? Will you stand, walk or drive over the
sorbent? Will it be under machines or surrounding machines? Will
it be on work tables?
These
and other questions help you determine the grade and type of
product needed, whether it be pads, rolls, socks, pillows, rugs,
etc.
