(2) Structural Requirements:

(a) The booth walls shall be permanently fixed barriers of at least seven feet (2.13 m) high;

(b) When a door or movable panel is used as an integral part of the booth structure, it must have an interlock which will prevent an exposure when the door or panel is not closed;

(c) Shielding shall be provided to meet the requirements of division 120 of these rules.
