OK - what you are smelling is the odorant Ethyl Mercaptan which is
added to natural gas to make it detectable. Somehow the mercaptan is
being released into the air - with or without the gas. My suspicion is
some has "settled out" of the gas at the pilot. Only a fraction of a
small drop will be detectable by a sensitive schnozz.

To date they've never been able to set off their high-priced,

I've become convinced by characteristics it's a remnant of the odorant

Odorant can fool you.
I worked at a place out in the country that had a small motel for new emplo
yees until they found a place. There were maybe a dozen rooms. The place
smelled so strong of gas I wouldn't have walked near it. Their claim was t
hat it was normal. The odorant addition machine only came in one size, and
so they had a large unit for that tiny motel. With that much odorant bein

In hindsight, they were probably lying, but we all did survive. And move o
This is a farm residence/homestead; the pot is at the tap off the

brings up other stories that initially was un-metered tap for farm/house
use as part of the right-of-way easement grandfather negotiated in the
30's when they built the line. Some 30 yr ago now, the original
pipeline company was acquired by another and they somehow found an
escape hatch that state corporation commission backed them up on to
break all those existing agreements. I've been extremely surprised they
haven't come around trying to pull the tap entirely in order to get rid
of the hassle of these scattered residential taps all over the county...

Given that propane is heavier than air, having a *small* propane leak in a house with a basement or below grade crawl space is an explosion waiting to happen.
A *small* propane leak is probably less dangerous in an above grade slab house.
Given that natural gas is lighter than air, a *small* natural gas leak seems far less dangerous.
No "safe amount" of any explosive gas can be detected
by human nose. Our noses have not been trained to
discriminate between safe and unsafe odours. This is
why gas companies ask people to notify them if they
ever smell gas.
Natural gas has no detectable odor at all -- it's only the mercaptan
oderant added that can be detected by the nose. It's so strong simply
so that a tiny amount is detectable by almost everybody (albeit I can
often not notice the trace amounts spoken of above when some others
claim it smells strongly of it to them; my sniffer ain't so hot as some
The measurement devices used by the gas co aren't "smelling", they're
using active sensing to detect the actual methane/propane/whatever...

Getting more common - Co detectors are now MANDATORY in any living
space in Ontario, joining smoke detectors.
Many Co detectors are combination natural gas detectors. $63 is about
the average cost. Likely more like $40 yankee bucks.

I don't remember how the problem started. but the loud CO alarm woke me
up one night. I opened the window and turned off the oil furnace. It
was a cold night, and after a while I was torn whether to shut the
window again, so I could go to sleep. But I didn't want the big sleep.
The alarm wasn't alarming, but I think I had a slight headache and
didn't want to take chances. But it was getting cold quickly. After 20,
25 minutes I shut the window and went back to sleep.
Next day called the furnace guy. He took off the 6" stove pipe leading

It's more than the difference in the buck (right now in the 88 cent

even taking exchange into consideration. I guess having a market ten

I know a lot of electronics products made in Japan, or at least made by
Japanese companies in countries near them, are cheaper in the US than in
Japan. But I thought that had to do with Japanese taxes or something.
(I don't know what prices are like in China, or how many Chinese can
afford to buy their products, even at US prices.)
I would think one could treat Canada as any 30 million person section of
the US. Most chains in the US don't cover the whole country, or if
they do like the mail-order catalog, I mean webpage, of Sears, they are
still just one of many buyers.
Does NAFTA only affect things made in the US, Canada, and Mexico, and
not how Chinese or Japanese companies exporting here elate to us?
