Odor Present on Delivery Ticket

Odor Present -- Yes-No

Odor Present—Yes-No

The odor present box on your delivery ticket should ALWAYS be checked “yes”—it does not mean that there is a leak in your propane system.

Propane is a naturally odorless gas.

Typically, an odorant called mercaptan is added to propane to provide a distinctive odor or smell.

This allows the consumer to detect if there may be a problem with the propane system.

The History of Propane

The Discovery
In 1910, Dr. Walter O. Snelling, a chemist and explosives expert for the U.S. Bureau of Mines, was contacted to investigate vapors coming from a gasoline tank vent of a newly purchased Ford Model T. Dr. Snelling filled a glass jug with the gasoline from the Ford Model T and discovered on his way back to the lab that volatile vapors were forming in the jug, causing its cork to repeatedly pop out. He began experimenting with these vaporous gases to find methods to control and hold them. After dividing the gas into its liquid and gaseous components, he learned that propane was one component of the liquefied gas mixture. He soon learned that this propane component could be used for lighting, metal cutting, and cooking. That discovery marked the birth of the propane industry.

The Growth of an Industry

1912 Dr. Snelling and colleagues established the American Gasol Co., the first
commercial marketer of propane.
1913 Dr. Snelling sold his propane patent for $50,000 to Frank Phillips, the founder of
Phillips Petroleum Co. In 2002, Phillips Petroleum merged with Conoco Inc. to
form ConocoPhillips.
1918 Propane was primarily used for cutting metals. J.B. Anderson of Sharpsburg, PA
developed the first propane-fueled pumpless blowtorch.
1922 The Bureau of Mines, which is part of the U.S. Department of the Interior, began
tracking propane sales in the United States. National sales totaled 223,000 gallons.
1925 Propane sales reached 404,000 gallons—nearly doubling sales in just three years.
1927 Phillips Petroleum, now ConocoPhillips, began the research and development of
domestic appliances and gas equipment. The Tappan Stove Co. began producing
gas ranges. Today, Tappan Stove is part of Electrolux Home Products.
1928 The first bobtail truck was built to transport propane. Servel Inc., which went out of
business in 1958, produced the first propane refrigerator.
1929 Aggressive sales promotions and marketing pushed national sales to 10 million
gallons. The propane industry asset value was approximately $22 million.
1931 H. Emerson Thomas, George Oberfell, and Mark Anton founded the first propane
industry trade group called the National Bottled Gas Association in Atlantic City,
1932 At the 1932 Olympics in Los Angeles, CA, propane powered all of the appliances
for cooking and heated the water in the Olympic Village.
1933 A propane odorant was developed to easily detect leaks.
1934 National sales reached 56 million gallons, due in great part to rapid industrial
1936 Twenty-pound cylinders, such as those used for grilling, were first introduced to
enhance portability.
1945 The end of World War II brought great industrial development, leading propane into
its so-called “Golden Years.” Sales reached 1 billion gallons.
1947 Sixty-two percent of all U.S. homes were equipped with either natural gas or propane ranges. Water heater sales rose 261 percent, and the first propane-fueled clothes dryer entered the marketplace. The first oceangoing tanker built for propane, the SS Natalie Warren owned by Warren Petroleum Corp., was launched; total capacity was 1.4 million gallons.
1950 The Chicago Transit Authority ordered 1,000 propane-fueled buses, and Milwaukee converted 270 taxies to run on propane. In addition, an estimated 7.5 million propane installations occurred on farms and in suburbs.
1955 Propane containers, equipment, and appliances were exposed to an atomic explosion at a federal test site in Nevada. After the explosion, all were in perfect working order, and the ranges were used to cook meals for the test personnel.
1958 National propane sales reached 7 billion gallons annually.
1961 Propane installations in the United States totaled 13 million tanks.
1962 The propane industry celebrated its 50th anniversary at its national convention in Chicago during May.
1963 The first 50,000-gallon tank car was built, and hot-air balloons began using propane.
1965 GATX built the world’s largest propane tank car, with a 60,000-gallon capacity.Chevrolet introduced four new truck engines designed for propane.
1973 Propane price controls were instituted in the wake of the Arab oil embargo. The propane industry trade association, now called the National Propane Association, opened its first Washington, DC office.
1977 The U.S. Department of Energy was established, and the Federal Energy Administration (FEA) began investigating propane pricing practices, which were then controlled by the U.S. government.
1981 President Reagan eliminated price controls on propane, gasoline, and crude oil.
1987 The National Liquefied Petroleum Gas Association (NLPGA) changed its name to the National Propane Gas Association, the national trade association representing the propane industry.
1990 Propane was listed as an approved, alternative clean fuel in the 1990 Clean Air Act and, two years later, was listed again as an alternative fuel in the Energy Policy Act of 1992.
1996 The Propane Education & Research Council (PERC) was authorized by the U.S. Congress with the passage of Public Law 104-284, the Propane Education and Research Act (PERA), signed into law on October 11, 1996. PERC’s mission is to promote the safe, efficient use of odorized propane gas as a preferred energy source.
2004 Today, propane is an $8 billion to $10 billion industry in the United States and is growing. The United States consumes more than 15 billion gallons of propane annually for home, agricultural, industrial, and commercial uses. Of the 101.5 million U.S. households, 8.1 million depend on propane for one use or another.
