Hi Chito,
<div><br>
</div>
<div>We have some sloppy conditions during the winter here and all year round. Plus, our entrance is via a cafe.</div>
<div><br>
</div>
<div>Our first step, and to avoid over-taxing our shoe cleaner, is to clean the bulk of the matter off with a mud cleaning brush (see attached). <span style="background-color: rgba(255, 255, 255, 0);">The stiff bristles do remove the larger clumps. </span>After
this step, the user enters the lobby and uses the auto shoe cleaner (with vacuum and HEPA). </div>
<div><br>

<div><br>
</div>
<div><br>
</div>
<div>The key is make sure people actually check their boots and shoes. Some stuff may stick all the way through the gown donning process. When users doff their pre-gowning materials and remove their booties while exiting during the dirtiest months, and do
so in the gowning room/area, the clumps that remained stuck to the shoes can now come off within the pre-gown room (or gown room if combined). We currently have all users completely leave the clean room, remove the CR garments and hang them, and exit the
pre-gown room entirely before taking off any of their hair covers, gloves, or shoe covers. This has kept our pre-gown room and gown room much cleaner, and therefore keeps the Cleanroom cleaner.</div>

<p>Does anyone have shoe cleaners in their gowning room for users? We get over 200' of snow during winter and this often is brought into our facility, including the gravel and salt that is put down by facilities. We are currently thinking about how our gowning
area is done and were thinking about installing shoe cleaners for the users that forget to bring a spare pair of shoes.<o:p></o:p></p>
<p>So far I have only seen one that might be rated "Bulldog 351 Shoe Brush Machine" for the type of debris that might be brought in.
