Jeff and Patrick,

I’ve attached the standard operating procedure and shut down notices for servicing lab exhaust systems. It may be necessary to share this with siemens as well. Here are a couple of key things to note from the SOP;

PF and building deputy will communicate/coordinate with the labs and lab PIs the need for service and the duration of the fan shut down.

Except for emergency situations, PF personnel will post the “Shut Down Notice” on the affected chemical fume hood(s) a minimum of three days prior to the scheduled shut down. The notice should be posted in the lower, center area of the sash so that it is easily visible. The affected hood(s) will be out of service during the period indicated on the notice regardless of whether or not the fan is actually operating. If the exhaust system being serviced provides ventilation for an entire room, the “Shut Down Notice” should be placed on the door to the room.
The laboratory PI must ensure and sign off on the “Shut Down Notice” that hazardous materials have been secured, the sash remains closed and no operations/experiments, including closed systems, shall be conducted in the chemical fume hood(s) for the duration of the maintenance as indicated on the posted notice.
PF personnel will verify that all chemicals and equipment have been secured or removed from the hood and the Laboratory Personnel section of the “Shut Down Notice” has been completed before maintenance work begins.

Let me know if you have any questions or concerns.

Thanks,

Subject: FRNY Manifold/Air shutdown

Jeff,

The siemens contractor is requesting a shutdown this Thursday, June 22^nd. This would take down the fume hoods on the newer side of Forney and HVAC supply air would be backed down to prevent damage to the roof and also keep egress in and out of laboratory doors possible.

I have copied EHS for awareness.
