Sec.  108.175  Contiguous locations.



    An enclosed space that has direct access to a Division 1 or Division 

2 location is the same division as that location, except--

    (a) An enclosed space that has direct access to a Division 1 

location is not a hazardous location if--

    (1) The access has self-closing gas-tight doors that form an air 

lock;

    (2) The ventilation causes greater pressure in the space than in the 

Division 1 location; and

    (3) Loss of ventilation overpressure activates an alarm at a manned 

station;

    (b) An enclosed space that has direct access to a Division 1 

location can be considered as a Division 2 location if--

    (1) The access has a self-closing, gas-tight door that opens into 

the space and that has no hold-back device;

    (2) Ventilation causes the air to flow with the door open from the 

space into the Division 1 location; and

    (3) Loss of ventilation activates an alarm at a manned control 

station; and

    (c) An enclosed space that has direct access to a Division 2 

location is not a hazardous location if--

    (1) The access has a self-closing, gas-tight door that opens into 

the space and that has no hold-back device;

    (2) Ventilation causes the air to flow with the door open from the 

space into the Division 2 location; and

    (3) Loss of ventilation activates an alarm at a manned control 

station.
