92 Ill. Adm. Code 449.40
Container Installation
Section 449
Section 449.40 Container
Installation
In addition to the requirements
established by Section 449.30, installation shall comply with the following:
a) Compressed or liquefied gas containers shall not be mounted in
the passenger or driver's compartment.
b) Container valves, appurtenances and connections shall be
mounted in an enclosed compartment.
c) Containers shall be located at least 36 inches from the
entrance door and any emergency exit. Due to the smaller size of Type II
school buses, space limitations may sometimes make it impossible to locate a
fuel tank further than 36 inches from an exit.
A Type II school bus has a
gross vehicle weight rating of 10,000 pounds or less
as defined in Section
12-800 of the Illinois Vehicle Equipment Law (Ill. Rev. Stat. 1987, ch. 95½,
par. 12-800). If the original fuel tank for a Type II bus was located within
36 inches from any exit, the alternate fuel container may be located in the
same location as the original tank.
