I buy butane in bulk, and add 200 millileters ethyl mercaptan to 7,500
gallons going into the bulk tank with a draft attachment for scenting. This
is to prevent contamination of the transport truck, as they haul different
varieties. I'm told by my supplier that tomato juice will kill the smell
about as quick as anything will. He related a story about an employee
accidently dropping a barrel of mercaptan from a handcart and the barrel
split. After evacuation of the area, they called in two 8,000 gallon loads
of tomato juice and sprayed all over the compound. He said the cleanup of
the juice was a bitch in and of itself.

I've heard that the odor is so strong and so bad
close up that it can cause people to become physically
ill. Is this true?
