Sec. 192.171  Compressor stations: Additional safety equipment.

    (a) Each compressor station must have adequate fire protection 
facilities. If fire pumps are a part of these facilities, their 
operation may not be affected by the emergency shutdown system.
    (b) Each compressor station prime mover, other than an electrical 
induction or synchronous motor, must have an automatic device to shut 
down the unit before the speed of either the prime mover or the driven 
unit exceeds a maximum safe speed.
    (c) Each compressor unit in a compressor station must have a 
shutdown or alarm device that operates in the event of inadequate 
cooling or lubrication of the unit.
    (d) Each compressor station gas engine that operates with pressure 
gas injection must be equipped so that stoppage of the engine 
automatically shuts off the fuel and vents the engine distribution 
manifold.
    (e) Each muffler for a gas engine in a compressor station must have 
vent slots or holes in the baffles of each compartment to prevent gas 
from being trapped in the muffler.
