Sec.  176.93  Vehicles having refrigerating or heating equipment.

    (a) A transport vehicle fitted with refrigerating or heating 
equipment using a flammable liquid or Division 2.1 (flammable gas) 
material, or diesel oil as fuel, may be transported on a ferry vessel. 
However, the refrigerating or heating equipment may not be operated 
while the vehicle is on the vessel, unless the equipment complies with 
the following requirements:
    (1) The installation is rigidly mounted and free of any motion other 
than normal vibration in operation;

    (2) An easily accessible shutoff control is fitted to the fuel and 
electrical supply of the refrigerating or heating equipment; and
    (3) The fuel storage tank, the fuel lines, the carburetor and any 
other fuel devices are tight and show no signs of leakage.
    (b) If the vehicle operator desires to operate the refrigerating or 
heating equipment while on the vessel and the equipment is not fitted 
with automatic starting and stopping devices, it must be started before 
the vehicle is taken on board. It may continue in operation while the 
vehicle is on the vessel, but if the motor stops it may not be 
restarted.
    (c) In the case of a ferry vessel on a voyage exceeding 30 minutes' 
duration, stowage must be provided for transport vehicles having 
refrigerating or heating equipment operated by internal combustion 
engines which will permit ready diffusion of exhaust gases to the open 
air. Passenger vehicles may not be stowed in a position adjacent to 
vehicles operating internal combustion motors which expose the occupants 
of the passenger vehicles to excessive concentrations of exhaust fumes 
from such motors.
    (d) A transport vehicle containing solid carbon dioxide as a 
refrigerant may be transported on a ferry vessel only if it is stowed in 
a well ventilated location.
