Blast in Enclosed Space Kills 2, Hurts 1

Moments before a blast ripped through a railcar on April 14, a check of the air quality inside indicated a serious risk of an explosion.

Despite that warning, Nebraska Railcar Cleaning Services sent two employees, aged 41 and 45, into the railcar to work without monitoring the air continuously for explosive hazards as required, nor providing the employees with emergency retrieval equipment or properly fitted respirators, said officials at the Occupational Safety and Health Administration (OSHA).

The explosion that resulted blew the railcar’s escape ladder off and killed the two men, trapping one inside and hurling the other off the top of the railcar. A third employee suffered an injury.

While this was not a true industrial control environment incident, it does go to show what could happen when precautions are not taken when people work in an enclosed area.

After its investigation at the company’s Hickory Street, Pierce Street and South 30th Street sites following the explosion, OSHA cited Nebraska Railcar Cleaning Services for seven egregious willful, three willful, two repeated, 20 serious, and one other than serious safety and health violations.

The company faces penalties of $963,000. OSHA also placed the company in the agency’s Severe Violator Enforcement Program.

“Our hearts go out to the families of these workers, whose deaths were so senseless and preventable,” said Dr. David Michaels, assistant secretary of labor for occupational safety and health. “This isn’t the first time this employer put its workers’ lives at risk – but OSHA will do everything in our power to ensure it is the last.”

The egregious willful violations involve multiple instances of failing to monitor air quality properly in confined spaces as required and for not fit-testing employees required to use respirators in railcars. Most railcars fall under the category of confined spaces, which are large enough for workers to enter and perform certain jobs, such as cleaning and maintenance, but are not designed for continuous occupancy. Safety regulations require employers evaluate confined spaces for air quality and other hazards prior to allowing workers to enter and then monitor conditions while employees are inside.

“This company has regularly failed to use appropriate equipment and procedures to keep their employees safe, and in this case it had tragic consequences,” said Jeff Funke, OSHA’s area director in Omaha. “The company needs to immediately reevaluate its procedures for entering and cleaning railcars.”

In the most recent citations, Nebraska Rail Car Services also failed to:
• Train workers on hazard materials in use
• Establish a hazardous waste program to include training, proper handling and removal
• Label containers for chemical hazards
• Guard floor openings to prevent fall hazards
• Establish a hearing conservation program
• Provide first aid and fire extinguisher training
• Remove damaged powered industrial vehicles
• Numerous electrical safety violations
• Train workers on safely operating powered industrial vehicles, a violation the company received a citation for in 2013

Nebraska Railcar Cleaning Services and Omaha Transloading LLC share a majority owner, Steven Braithwaite.

The company specializes in cleaning railcars that contained food grade products, herbicides, pesticides, fertilizers, used oil, asphalt, gasoline, and ethanol. At the time of the 2015 inspection, it employed 35 workers at three locations in Omaha.
