Natural Gas Smell: Scratch-and-Sniff Cards
"The smell of a suspected natural gas leak in Great Falls, Mont., Wednesday was traced to discarded scratch-and-sniff cards, a gas company manager said.
The cause, though, was boxes of scratch-and-sniff cards designed to educate customers what a gas leak smells like. The cards had been thrown out, then hauled away and compacted in garbage trucks, Nick Bohr, general manager of Energy West, said."
Natural gas doesn`t have any scent, but chemicals with a distinctive smell are added to gas so that customers will be aware of any gas leaks.
The scratch-and-sniff cards were given away to customers by the gas company as an educational tool. In a way the cards worked beyond their expectations, everybody blamed a gas leak for the odor caused by the scratch-and-sniff cards.
Several buildings were evacuated before the cause for the odor was discovered. In the future it might be a good idea to burn or bury any surplus scratch-and-sniff cards.
