Sufficient concentration of the highly stinky gas, hydrogen sulfide, will
knock out one's sense of smell. Is it possible that the same applied to its
methyl analog?

The initial statement about the amount of Mercaptan let loose and undetected
is also at odds with common sense :

"Chemical manufacturer DuPont has reported that about 23,000 pounds of a
flammable toxic chemical escaped in the building where four of its workers
died two weeks ago at a Houston-area plant.

DuPont disclosed in a news release the quantity of the methyl mercaptan that
led to the deaths Nov. 15."

Did anyone else find this tidbit odd? How could there be methyl mercaptan
vapor build up and no one notice it? Around here, someone takes the sealed
jar out of the dessicator to take to the fume hood and there's howling up
and down the hall from the smell.

HOUSTON -- It was DuPont's third deadly U.S. accident in five years and the
deadliest of them all. On November 15th, a chemical leak in LaPorte took the
lives of four workers, including two brothers.

They were inside a building that manufactured insecticides.

Federal investigators have now claimed there were problems both with the
building and with how things were done there.

"What we are seeing here in this incident in LaPorte is definitely a problem
of safety culture in the corporation of DuPont," said Rafael Moure-Eraso,
Chairman of the U.S. Chemical Safety Board.

After months of investigating, the independent agency found a ventilation
system had been broken that allowed a harmful chemical called methyl
mercaptan to build up without anyone knowing it.
