State workplace safety officials have closed the investigation into whether Assemblyman Steven Brooks is a danger to Legislative Counsel Bureau employees.The investigation was requested by an unnamed LCB employee who said Brooks was “an unstable and dangerous employee who has been allowed to remain in this building despite many of our colleagues’ concerns.”LCB Director Rick Combs responded to the letter from the Occupational Safety and Health Administration with a list of actions he has taken to ensure the safety of both visitors and employees in the Legislative Building.After reviewing that response, Chris Davis, OSHA district manager in Northern Nevada, responded with a brief letter closing the case.“With this information, OSHA feels the case can be closed on the grounds that the hazardous conditions have been corrected or no longer exist,” the letter said.The response by Combs came just hours before Assembly Majority Leader William Horne announced that Brooks had been banned from the building pending resolution of the situation — a move that helped resolve the complaint.According to the letter, a Legislative Police officer accompanies Brooks when he is in the building. His key-card has been deactivated so he can’t enter after hours without contacting Legislative Police.“Assemblyman Brooks further allowed the legislative police officers to take whatever precautionary measures they requested to ensure that he is not armed when he enters the building,” the response states.Panic alarm buttons have been installed at the desks of employees most worried about Brooks.
