# List of pipeline accidents in the United States (1900–1949)

The following is only a sample of natural gas and petroleum product accidents for this era. Gas and oil leaks and explosions were not tracked in an organized fashion except by fire marshals. Many leaks, fires, and explosions were not recorded unless they occurred in population centers with newspapers to report them.
Later in the twentieth century, the Pipeline and Hazardous Materials Safety Administration (PHMSA), a U.S. Department of Transportation agency, would be established to develop and enforce regulations for the safe and environmentally sound operation of the United States' pipelines, and to collect data on pipeline leaks, accidents, and explosions.

## 1900s
### 1900

* December 20 – In Beaver Falls, Pennsylvania, two children were fatally burned and five injured in a gas explosion and fires that destroyed three houses. The explosions were caused by the breaking of a valve gate on the Fort Pitt Gas Line, which allowed leaking gas to seep into the houses' cellars, following water pipes from the street.

### 1901

* May – Three teachers and a plumber were injured by a gas explosion at Saint Michael's Roman Catholic Church parish school in Pittsburgh, Pennsylvania.
* October – In Boston, Massachusetts, five women narrowly escaped being burned alive after a leaking gas meter exploded in the basement of their three-story tenement, starting a fire that ascended through the stairwells and drove them out the upper windows where they clung to the ledges until firefighters rescued them with extension ladders.

### 1902

* February 21 – In Rochester, New York, an explosion destroyed a building at the works of the Rochester Gas and Electric Company. The loss was estimated at $20,000.

### 1903

* May – An oil well driller in eastern Ohio struck gas which ignited and exploded after escaping from the well. The derrick burned, and three men and an eight-year-old boy were seriously injured by the explosion.

### 1904

* January – In Marion, Indiana, three were killed, four fatally injured and eight dangerously injured when a hotel burned after a gas leak exploded, probably due to increased pressure in the mains. The loss was estimated at $50,000.
* December 1 – In Winchester, Massachusetts, a lighted match dropped into a sewer manhole by an employee of the Arlington gaslight company set off an explosion which injured five gas line repairmen and blew the steel manhole cover 30 feet into the air. The gas ignited along the sewer line into Rangeley, where two more manhole covers were blown into the air. The gas company's official statement was that the gas was ignited by a spark from a pickaxe.

### 1905

* February – In Hastings, Pennsylvania, two employees of the Hope Gas Company were killed while repairing a leak in a 12-inch diameter natural gas pipeline, which exploded so violently that their clothes were blown off their bodies.

### 1906

* November 22 – In Cherryville, Kansas, five Australians working on the Kansas Natural Gas Company's pipeline to Joplin were badly burned by an explosion "through misunderstanding or neglect."

### 1907

* August – A gas explosion shook Boston's South End after new machinery ignited a gas leak in the one-story brick engine house of the Boston Consolidated Gas Company, where natural gas was pumped to three huge reservoirs holding 2,000,000 cubic feet of gas. The engineer, knowing the fire could spread to the reservoirs, ignored his burning clothes and rushed to close the valves between the engine house and the reservoirs, saving the South End from a disaster. Seven workmen including the engineer were seriously injured.

### 1908

* March 28 – In South Deerfield, Massachusetts, a tank used for supplying gas to houses and stores exploded, killing two men and injuring two others. Hundreds of windows shattered from the force of the blast, and a small building near the tank was demolished. Leaking gas was thought to have been ignited by the flame from a lantern.
* July 31 – In Haysville, Pennsylvania, a gas explosion demolished a varnish factory building and broke 500 windows in the town, doing $6000 of damage.

### 1909

* December 14 – In Topeka, Kansas, six men were seriously injured when gas trapped in a fire cistern exploded. Two were cleaning out the cistern when another man struck a match to light a cigar and the explosion followed.

### 1911

* January 15 – Four persons were killed and four injured in a natural gas explosion at Niobrara, Nebraska. The explosion was caused by a leak from a gas plant in a hotel's cellar. The resulting fire burned the three-story frame hotel to the ground.
* June 26 – In Estes Park, Colorado, an explosion of gas in the Stanley Hotel endangered the lives of 20 guests and fatally injured one. The Stanley, a new $500,000 four-story hotel lighted by electricity, had a gas plant for emergency use. Guests noticed the odor of gas the previous day and at night the leak was found on the second floor by employees with lighted candles who set off the explosion.
* September 18 – In Schenectady, New York, the explosion of a gas generating tank in the basement of the Exchange building resulted in the death of the owner of a confectionery store. The building was considerably damaged by the fire which followed the explosion. Firemen found the confectioner's body in the basement.

### 1912

* May 13 – In Parkersburg, West Virginia, a gas explosion shook a woolen mill and injured three men, probably including the one searching for the gas leak with a lighted match.

### 1916

* July 12 – In Lafayette, Colorado, an explosion at the Western Light and Power Company injured none of the eight men in the building. Employees said the explosion was caused by accumulation of natural gas in the economizer in the fan room. The explosion did not interrupt gas service. The explosion in the feed pipes blew out the west wall of the fan house, causing about $1,000 in damage.

### 1917

* January 1 – In South Boston, Massachusetts, a paper boy was killed by a flying manhole cover, 11 persons were severely injured and property damage running into thousands of dollars was entailed in a terrific gas explosion that threw 13 manhole covers into the air. When gas company employees used pickaxes to uncover the leak to repair the pipe, it flamed up again.
* January – Near Ouray, Colorado, an untapped seep of natural gas near the ferry across the Green River exploded in a blast that was heard two miles away and hurled blocks of ice five feet square and more than a foot thick onto the riverbank.
* February 2 – In Chicago, Illinois, a gas explosion wrecked a tenement house, killing seven residents and injuring 21. Another 27 were missing. After the explosion, a pillar of fire rose from the ruins, indicating that gas was still leaking.

### 1918

* December 30 – In Lebanon, New Jersey, 12 people were killed and 12 others injured by two gas explosions in the post office's basement tank of artificial gas. The first explosion blew the roof from the building and the second caused the walls to collapse, burying victims in the debris. Nearly 20 persons were waiting in the post office for the evening mail when the explosions occurred, and everyone in the building was killed or injured. Several in the street were hurt by falling debris. Some of the injured were badly burned before they could be rescued from the wreckage.

### 1919

* February 16 – In Salt Lake City, Utah, natural gas escaping into a home nearly suffocated two boys and their dog. When their mother returned to the house, a wave of gas met her as she opened the door: the dog could only crawl and the boys were nearly asphyxiated by the gas but revived when treated at the hospital.

### 1948

* February 28 – Crude oil spilled from a ruptured pipeline leading to storage tank in Oklahoma City, Oklahoma. Some teen boys in the area saw crude oil bubbling out of manhole covers, and thought that igniting the oil would be a good idea. This caused a string of sewer explosions, causing manhole covers to fly 10 feet (3.0 m) into the air.
* March 18 – The 20 inch diameter "Little Big Inch" natural gas transmission pipeline near Petersburg, Indiana exploded and burned, throwing pieces of the pipe as far as 300 feet (91 m) away from the blast point. 3 homes were destroyed by the fire.
