Pat Keogh has just sent me this message

Just a bit of info on what is happening today Between 1.00pm and 2.30pm we will be testing the fans in the two tower stairs, this means the fans will run and our staff member will hold the bottom door open to get the correct air flow, they will not let anyone exit. Please let the help desk know as the door alarm buzzer will operate.
We will do one stair at a time.

Thanks

Tim O’Sullivan
