Question 19

Ch14: Norman – Multiple Dwellings
(NC #19)

Answer 19

Approved self-closing devices

Question 20

Ch14: Norman – Multiple Dwellings
(NC #20)

Unfortunately, many people remove this critical safety factor by disabling the self-closing device for their own convenience. This is especially true in:

Question 22

Ch14: Norman – Multiple Dwellings
(NC #22)

Larger MD’s require means of bringing ventilation & daylight to the rooms in the middle of the bldg. These light & airshafts pose a danger of fire extending horizontally across the shaft (often bypassing a fire wall), as well as vertically due to:
