[PEPPo] installation update

[Joe Grames]

Dear PEPPo Collaborator:

Activities are already underway in preparation for the installation of 
the experimental apparatus later this summer.  This means work is going 
on both at surface level in the Injector Service Building (ISB) and 
tunnel level in the injector region of the accelerator enclosure.   You 
will begin to receive regular installation updates about new or on-going 
activities.  You should read these and ask questions if you are 
unclear.  Presently, a handful of us are in a position to be working in 
these areas, but at the summer progresses many more collaborators will 
be in this position.

1. _*Cable Penetrations Opened*_ - Two cable-way penetrations which 
connect the ISB to the tunnel at locations IN02B23 & IN02B24 were opened 
today, meaning the stones which fill the penetration have been dumped 
out of each preparation in preparation for pulling new cables (HV, 
signal, magnet, etc) through them.  For the duration these penetrations 
are open the work area around and above the racks is elevated from ODH-0 
to ODH-1.   For those who already have Oxygen Deficiency Hazard (ODH) 
training, this means the two-person buddy-rule is in effect.  Signs have 
been placed to define the area and an ODH monitor has been placed above 
the region, and will be activated Thursday morning 6/2.  As usual, if 
the ODH system ever goes into alarm (blue beacon & horn) you must exit 
the building.  If this doesn't make sense to you then you probably 
haven't taken ODH training, so you shouldn't yet be working in this area.

2. _*Work Area Personal Protective Equipment (PPE)*_ - The injector 
accelerator enclosure downstream of the cryounit (plastic curtain) is 
now an installation area.  Personnel in this area should wear closed 
shoes (no sandals) and pants (no shorts).  In addition, it is 
recommended that those working below the open penetrations wear safety 
glasses and hardhats as small stones and or materials can drop from the 
surface level to the tunnel level.

3. _*Injector Walkway Installation Planned Next Week June 6th*_ - The 
new injector platform at the injector accelerator enclosure is on track 
for installation next week and will last 2-3 days.  During the 
installation please pay attention to any posted signs.  The task 
includes a significant amount of drilling and hammering, with some dust 
and noise.  During these activities avoid the work area if possible.

As always, if questions/issues arise you can contact me on my cell 
757-344-0188.

Joe
