The government is proposing $91,000 in penalties against Oklahoma’s Wynnewood Refining Co. for allegedly failing to protect employees from hazardous working conditions.
The Occupational Safety and Health Administration proposed the penalties after citing Wynnewood with three serious and two repeat violations of OSHA standards.
OSHA began investigating on April 21 following an explosion due to the release of flammable liquid and vapor from an open piping system during preparation for maintenance.
The facility, which produces gasoline, butane, fuel oils and asphalt, employs 210 people.
The three serious violations were for failing to document and implement OSHA rules concerning equipment deficiencies, operator training and safe working practices.
The two repeat violations were for failing to document design codes, written procedures for normal operations and written procedures for mechanical integrity.
