Here is what we are using at Hewlett Packard Labs:


Cleaning Protocol

Process:

  *   Mop floor with cleanroom mop and water
  *   Empty recycling and waste bins - 6 dome bins-4 located in each cleanroom aisle, 1 service chase,  and 1 gas corridor AND 2 bins in gown room stainless steel dispenser.
  *   Do not empty or touch red Hazardous waste bins
  *   Vacuum floors- use green Cleanroom vacuum only- not Nilfisk vacuums dedicated to tools
Emergency

  *   Safety first!  Get out if Fire or gas alarm goes off
  *   Alarms: Blue light or high pitched siren with flashing strobe light- exit the building.
  *   Spill kits- contain absorbent materials.  Test all unknown liquids with Ph paper before cleaning up.
  *   Eye wash station- form perimeter to spill.  Test liquid with Ph paper.  If green, Ph= 7, then is water (if they know how and are comfortable).  Proceed to form perimeter to spill with PIG absorbers from spill kit
  *   See attached Emergency booklet
Clean floors frequency: Monday, Wednesday, Friday
Clean walls, glass windows:  Monthly, first Wednesday of the month
Vacuum floors to remove big particles, then mop with water

Dirty mop water can be dumped outside on the concrete pad drain (see photo for location, half way in, towards building)


Blue Sticky Mat Cleaning

Sticky mats- important defense in keeping particles out of the cleanroom.

  *   Spray mat with cleaner
  *   Squeegee back and forth (north to south, east to west), pulling dirt off the map
  *   Do not let water accumulate on the black borders of the mat!
  *   Divide mat into half or thirds sections, do one section at a time
  *   End by using mop to get dirt off the floor (should already be off the mat).
