Our early bird surf student Gautem has received 40m specific basic safety training today.

 Updated laser inventory and operator list. They are posted in the 40m wiki and entry doors of the 40m IFO room.

Let me know if this list needs correction.

Lightwave  M126N-1064-700 NPRO sn 337 in the PSL enclosure got connected to local emergency shut off switch. This is a LIGO operational safety requirement.

 Alex Cole and Craig Cahillane received 40m specific,  basic safety training last week.

All of us in the control room / desk area heard a sudden whoosh of air a few minutes ago.  It kind of sounded like a pressure washer or something.  We determined that the northmost nitrogen bottle outside the front door was letting out all its gas. 

It's a gazillion degrees outside (okay, only 91F, according to a google of "Caltech Weather"), and those bottles are in direct sun all day.

We are leaving the bottle as-is, since it seems like its has finished, and nothing else is happening.

Sujan got 40m specific basic safety training this morning.

Masayuki Nakano, a student of Seiji's from ICRR / U Tokyo, is visiting us here at the 40m lab for the next couple months.

 We had fire alarm tests  and evacuation drills at 1:30pm yesterday. All flashers and horns are functioning unbearably loud and bright including clean assembly room.

Chris Couste, our new undergrad help received 40m specific, basic safety training yesterday.

Facilities just came by and cleaned the smoke detector that is above Steve's desk.  It's next to an air vent, so I guess it collects dust more than a "typical" smoke detector.

 All 40m laser safety glasses are cleaned and measured this morning.  Bring your own safety glasses if you have to enter the 40m IFO room.

Glasses were washed in 1% Liquinox water solution and  their transmission measured at  165 mW,  2 mm OD beam of 1064 nm

 We had our annual safety inspection today.  Our SOPs are outdated. The full list of needed correction will be posted tomorrow.

The most useful found was that the ITMX-ISCT ac power is coming  from 1Y1 rack. This should actually go to 1Y2 LSC rack ?

 Please test this so we do not create more ground loops.

 Linus-1, Nodus and others  ac cords can be moved over to new blank yellow extension cord with multiple recepticals.

 Remove two red extension cords going to Smart UPS

 Annual crane inspection is scheduled for 8-11am Monday, March 17, 2014

The control room Smart UPS has two red extension cords that has to be removed: Nodus and Linux1

 KroneCrane Fred inspected and certified the 3 40m cranes for 2014. The vertex crane crane was load tested at fully extended position.

 Last long extension cord removed from 1Y1 to ITMX-ISCT

The AC power strip at ITMX-ISCT is coming from wall L#26

Be aware that this may affect POP QPD and POP RF Thorlabs PD

 Late adition: CHECK all viewport covers.

A, transparent Lexan sheet is protecting glass windows in a horizontal position

B, metal housing protection is required on each viewport except signal ports

C, signal ports should be shielded by optical table enclosure

We have to cover this window-camera with implosion proof cover or just remove it and blank it.

Question number 2: Do our vertically positioned windows with flip able covers require protective lexan ? NO 5-5-2014

This is the third safety glasses that I found laying around in the IFO lab lately. Safety glasses must be worn ALL times in the IFO room!

This rule is essential for your protection! Please do not enter if you can not put up with this regulation!

  Smoking Sorensen could have triggered the smoke alarm!

 Yesterday I called CIT Fire Protection Services very first to deactivate the sensors temporarily. The smoke alarm was turned back on right after the particle count dropped.

 Their phone number is posted at the entry doors 104M and 104W as shown below.
