Smoke control and "Désenfumage" systems

The intention of this technical note is to explain what a smoke control (SC) system is, and to what extent SC systems (and derivatives) are used at CERN. The role of ST Division in relation to these systems will be analysed, and some improvements suggested. This note is particularly addressed to people with local safety responsibility (TSO, DSO, etc.) but it also might be of interest to the CERN user in general. The complete list of facilities, under the responsibility of ST, having any relation with the control of smoke can be found at the end of the note.
