[labnetwork] gowning services and laundering vs. disposable

[Weaver, John R]

Richard -

I have not had good luck with any disposable gowns. While you may find that aerosol particle counts are not significantly affected - as long as the change-out is frequent and the gowns are maintained in good condition - surface particles and fibers tend to be a serious issue. The coated Tyvek is certainly superior to uncoated, but even with the coating fibers break loose on wearing. Additionally, the fragility of the garment is also a significant issue - bumping against a sharp corner on a piece of equipment is enough to tear the garment and give you a shower of particles and fibers.

Have you tried Environmental Products Warehouse (WWW.EPWHSE.NET)? I know they do quite a bit of mail-order business with their laundry and don't charge what the "big names" charge.

Subject: [labnetwork] gowning services and laundering vs. disposable

NREC at USF operates a class 1000 cleanroom servicing about 10-20 students per week with about 40-60 cleanroom entries per week. We have 3 sets of 20 gowns that we rotate out at regular intervals for cleaning.   We currently have our gowns cleaned by mail order but the current vendor wants to increase our contract rate by 10X the current amount, needless to say, this is not in our budget! The current company only seems interested in servicing high volume accounts and they want to move us to a minimum billing fee, based on their other clients usage.

Right now I'm looking for alternate companies that service the southeast market that will rent/repair and launder gowns via mail order for a smaller operation like ours. We've tried to contact several vendors but we've have not received any replies, based on this lackluster response I can only assume that the economy has picked up so well that they can afford to turn away business! 

We've always used laundry services and purchased/rented our own gowns, but I'm entertaining the idea of the standard coverall disposables but I have a few questions regarding their use that your feedback will help me determine if they will be cost effective for a smaller operation like ours.

1. would you consider using the disposable gown more than once, as long as they are not torn/tattered or soiled? it seems to me they would last for a few days or maybe even a week.
2. if you use disposables what is your policy regarding these gowns and replacement?
3. what brands/suppliers could you recommend. (I know there are many out there but I'm relying on the vast experience of Labnet to narrow down the playing field to a handful of contenders)
