Depending on how then line is constructed, it might change the area from unclssified to a classified area. Possible construction elements that would cause this is pipe joints, valves, connections etc.

(1) Indoor. Indoor installations shall comply with 110.26(F)(1)(a) through (d).
(a) Dedicated Electrical Space. The space equal to the width and depth of the equipment and extending from the floor to a height of 1.8 m (6 ft) above the equipment or to the structural ceiling, whichever is lower, shall be dedicated to the electrical installation. No piping, ducts, leak protection apparatus, or other equipment foreign to the electrical installation shall be located in this zone.

I don't believe propane would trigger a hazardous classification. NFPA generally excludes propane and natural gas piping/valves/utilization equipment from triggering XP requirements -- that is, the gas piping to the gas stove in your kitchen doesn't mean you need XP outlets and lights. My understanding of the reasoning for this (I think it's in the NFPA footnotes) is that the burners on the equipment are a bigger hazard than the electrical installation, so if the burners haven't set off an explosion than neither will your electrical stuff.
