Monro Muffler Brake Inc.’s Portsmouth, N.H., facility faces more than $221,000 in fines following an inspection by the Occupational Safety and Health Administration. OSHA inspectors found that workers were in danger of electric shock from exposed, energized wires, a hazard that the company did not correct after knowing of its existence. Defective work ladders, unsecured oxygen and acetylene cylinders, and inadequate eye washing facilities — hazards similar to those cited at company locations in three other states — accounted for five repeat violations. Serious citations also were issued for obstructed exit routes, improper storage and disposal of combustible material, damaged gas pressure regulators and inadequately grounded electrical equipment.
