According to the story, despite the high percentage, the number of violations is actually down from an average of 8.15 violations per office in 2007 to 1.75 violations per office this year.
The severity of the violations have also decreased, and generally include minor infractions like blocked electrical outlets, the story stated.
Peter Ames Eveleth, general counsel of the Office of Compliance, said: "In the past, we''ve found serious fire hazards such as blocked sprinkler heads, stacks of paper on heaters, fire doors obstructed by furniture and outlets with exposed live wires."
According to the story, 154 of the 541 congressional offices had zero violations, a marked improvement from 2008 when only 37 offices were in complete compliance.
OSHA officials say that increased education efforts combined with the lawmakers'' desire to maintain face in the eyes of the voters have resulted in the decrease of violations, but that there is still a long way to go for those that aim to receive the "Office Safety" award, the story noted.
