<br>HI Darrell,<br><br>I recall that the asbestos from this building was removed a number of years ago. If the building had asbestos originally, no amount of removal can get rid of asbestos completely. Regardless of what constitutes these particles, and what fraction of that makes it through the filter, would not it be wise to shut down the system until the holidays? <br>
<br>I am surprised only Jay on the fourth floor is concerned about his lungs. Those on the other floor can rest assured that one of the benefits of a centralized system is that it is just a matter of a few hours before the particles find their ways to every lungs.<br>
<br>Obviously, I don't know all the facts about asbestos. But even if there is a possibility, I think we should rather err on the side of caution.<br><br>Sooby<br><br><div class="gmail_quote">On Wed, Dec 2, 2009 at 10:59 AM, Jay Harris <span dir="ltr"><<a href="mailto:harris@attila.sdsu.edu">harris@attila.sdsu.edu</a>></span> wrote:<br>

<p class="MsoNormal"><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy;">The problem we face is having a continuous
flow of a high density of particulates I would estimate to be under 10 microns
in diameter. Most are probably sub-micron in size. All are easily
ported to the lungs. How can covering the vents with cheesecloth with 100-1000
micron sized holes be effective? </span></font></p>

<p class="MsoNormal"><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy;">Please locate someone who can provide
information concerning the health hazard of the profusion of these particulates
and let the faculty know of the dangers. This should be viewed as a very high
priority.</span></font></p>

<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">This week the contractor has begun system tests of the air
handler system being installed in the building. Several of you have noticed
dust and particulate in your offices. This has been especially evident in
offices in the North wing, particularly on the 4<sup>th</sup> floor. The
contractor should have covered the vents in these areas, especially where the
duct work has not been replaced. We had originally been told that the North wing
was not a part of this project, but as it turns out the new air handler has
been connected to the old duct system in that area. Since the new system has an
increased air flow, accumulated dust and particulates in the old ductwork were
being pushed out the vents. This morning the contractor covered all of the
known problem vents, and all areas at the end of duct lines. In addition, known
offices affected have been cleaned. If there is a problem in your office
or work area that has not been addressed, please let me know, and the
contractor will cover your vents and physical plant will clean your office or
work area.</span></font></p>
<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>
<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">For the remainder of this week, the system will be
undergoing tests, and balancing. The balancing will be done on Thursday and
Friday, and will start with offices or rooms that have temperature controls in
them. Eventually, they will visit all rooms to check the air flow and make
adjustments as necessary. Since they will be visiting all of the rooms during
this phase, the contractor asks for your cooperation in allowing them access,
and also expressed their appreciation for your cooperation and patience during
this construction. This is the final phase of this project, and if all goes
well this week, the system will be fully operational next week. We will have
air conditioning and heating to all the rooms connected to the new air handler.</span></font></p>

<p class="MsoNormal"><font size="2" face="Arial"><span style="font-size: 10pt; font-family: Arial;">Again, please let me know of any issues during this testing
and balancing phase, and I will bring them to the attention of the contractor.</span></font></p>
