9 til 5 - no.2

Had to venture into the bowels of the building to collect a parcel from the Loading Bay and spotted this on my way. In the event of an electrical fire in our Computer Hall, CO2 is the Fire Extinguisher of choice. I remember this used to freak me out whenever I had to do any work in the Computer Hall. I was told if I heard a popping noise I should get out of there quick smart!
