The oil and gas industry, the nation's chambers of commerce and politicians who are dependent upon campaign contributions from the industry and the chambers, claim fracking is safe.

First, close your mind to the myriad scientific studies that show the health effects from fracking.

Close your mind to the well-documented evidence of the environmental impact.

Focus just upon the effects on the workers.

The oil and gas industry has a fatality rate seven times higher than for all other workers, according to data released by the Centers for Disease Control (CDC). According to the CDC, the death rate in the oil and gas industry is 27.1; the U.S. collective death rate is 3.8.

"Job gains in oil and gas construction have come with more fatalities, and that is unacceptable," said John E. Perez, secretary of labor.

Not included in the data, because it doesn't include the past three years, when the oil/gas industry significantly increased fracking in the Marcellus and other shales, is a 27-year-old worker who was cremated in a gas well explosion in late February in Greene County. One other worker was injured. Because of extensive heat and fire, emergency management officials couldn't get closer to the wells than 1,500 feet. Pennsylvania's Act 13, largely written by the oil and gas industry, allows only a 300-foot set-back from wells to homes. In Greene County, it took more than a week to cap three wells on the pad where the explosion occurred.

The gas drilling industry, for the most part, is non-union or dependent upon independent contractors who often provide little or no benefits to their workers. The billion-dollar corporations like it that way. That means there are no worker safety committees and no workplace regulations monitored by workers. The workers have no bargaining or grievance rights; health and workplace benefits for workers who aren't executives or professionals are often minimal or non-existent.

It may be months or years before most workers learn the extent of possible injury or diseases caused by industry neglect.

"Almost every one of the injuries and deaths you will happen upon will have something to do with cutting a corner, to save time, to save money," attorney Tim Bailey told EnergyWire.

"Multiple pressures weigh on the people who work in this high-risk, high-reward industry, including the need to produce on schedule and keep the costs down," reports Gayathri Vaidyanathan of EnergyWire.

Tom Bean, a former gas field worker from Williamsport, says he doesn't know what he and his co-workers were exposed to. He does know it affected his health:

"You'd constantly have cracked hands, red hands, sore throat, sneezing. All kinds of stuff. Headaches. My biggest one was a nauseating dizzy headache. People were sick all the time and then they'd get into trouble for calling off sick. You're in muck and dirt and mud and oil and grease and diesel and chemicals. And you have no idea (what they are). It can be anything. You have no idea, but they (management) don't care. It's like, 'Get the job done.' .You'd be asked to work 15-, 18-hour days and you could be so tired that you couldn't keep your eyes open anymore, but it was 'Keep working. Keep working. Keep working.'"

Workers are exposed to more than 1,000 chemicals, most of them known carcinogens. They are exposed to radioactive waste, brought up from more than a mile in the earth. They are exposed to the effects from inhaling silica sand; they are exposed to protective casings that fail, and to explosions that are a part of building and maintaining a fossil fuel system that has explosive methane as its primary ingredient.

In July, two storage tanks exploded in New Milton, W.Va., injuring five persons. One of the injured, Charlie Arbogast, a rigger and trucker, suffered third degree burns on his hands and face. "You come to the rigs, you do what you do and you don't ask questions," Diana Arbogast, his wife, told the Pittsburgh Post-Gazette.

"In Pennsylvania, workers have reported contact with chemicals without appropriate protective equipment, inhalation of sand without masks, and repeated emergency visits for heat stroke, heat exhaustion, yet many of the medical encounters go unreported," says Dr. Pouné Saberi, a public health physician and clinical assistant professor at the University of Pennsylvania.

The oil/gas industry, the chambers of commerce, politicians, and some in the media, even against significant and substantial health and environmental evidence, erroneously claim there are economic benefits to fracking. Disregard the evidence that the 100-year claim for natural gas is exaggerated by 10 times, or that the number of jobs created by the boom in the Marcellus Shale is inflated by another 10 times. Focus on Greene County. Apparently, included in the "economic boom" is a small pizza shop that was contracted by Chevron to provide large pizzas and sodas to about 100 families living near the gas well explosion that cost one man his life.
