# 111.103-7 Ventilation stop stations.

Each power ventilation system stop station must:

(a) Be protected by an enclosure with a glass-paneled door on the front;

(b) Be marked, “In Case of Fire Break Glass and Operate Switch to Stop Ventilation;”

(c) Have the “stop” position of the switch clearly identified;

(d) Have a nameplate that identifies the system controlled; and

(e) Be arranged so that damage to the switch or cable automatically stops the equipment controlled.
