Explosive gas will not trigger carbon monoxide detectors, even at high concentrations. Usually people rely on the bad smell (like rotten eggs) that is added to natural gas/propane as a warning system. However, we have seen situations where gradual accumulation prevented detection due to nose blindness. A few years ago a man and woman came home from date night and could smell natural gas in their driveway as they pulled up. Their two teenage boys were at the back of the small house (1500 sq ft) playing video games and hadn't noticed a thing. One of them had nudged a kitchen stove burner knob and it was hissing out gas, filling the house. After that, they got one of the these alarms [amazon.com] and put it in their kitchen. Tested by leaving a burner slightly on, unlit...the alarm went off in under five minutes. I have the same unit in my own kitchen.
One last important point: if you smell gas in your house, do not start opening windows to air it out. Explosive gasses are only explosive at relatively low concentrations with air. Propane is only about 10%; methane around 15%. By the time you smell it, it's possible your concentrations could be higher than that. Opening windows could pull you back into the "danger zone". Don't ventilate; evacuate. Call the fire department. We can determine the concentrations and ventilation needs, as well as speed ventilations with fans that are low-risk for causing explosions.
Remember, as a general rule (in the US at least):
• We won't charge you for our help
• You are not bothering us
• If anything, you are probably making our day more interesting
• It is good practice for us
• We are then on-hand in case anything does explode
Alright, enough rambling from me. Be safe, everyone.

Edit: anyone else seeing weird line breaks anywhere I used italics/bold when viewing on the app? If so, I'll let mods know.

The link in one of the replies I was quoting. I also included it in my follow up post 2 or 3 after the one you've quoted here.

Call FD? Honestly, I would call them in either event (outside or inside). Dispatch will also notify the appropriate natural gas company and get someone out there...and while I'd like to say the companies respond faster when dispatch calls, YMMV. Around here, the gas company is great, but electric companies take forever (I once stared at a power line on a tree branch for 90 minutes before a worker showed). But in either event, the fire department will be able to respond fastest, can secure the scene/assess risk while awaiting the gas company, may be able to temporarily shut off the gas themselves (depending on the setup in the area), and will be on-hand if gas ignites. Basically, if you smell/detect a gas leak and have reason to believe it is not minor and fixable by you, you should clear the area and call 9-1-1. Better to have us and not need us than to need us and not have us.
Placement: directly under the gas pipe is probably fine if it is fairly close by. Methane is lighter than air; propane is heavier than air...but when leaks occur, usually neither is just strolling into the area. They are being ejected from a pressurized tube, which means they will shoot in a given direction before drifting. How close to the pipe is the alarm you placed under it? I'd say as long as it's within 5 feet or so, you're probably fine. Those things are quite sensitive. I was able to read detection of holding down a cigarette lighter's gas button and putting it about six inches from the detector.
