For the second time in as many months, Anne Arundel County paramedics were alerted to the presence of dangerous levels of carbon monoxide on the scene of a call by carbon monoxide detectors carried on their medical equipment.  On Sunday February 16th just after 1:30 p.m., paramedics responded to the Westin Hotel, located at 1110 Old Elkridge Landing Road in North Linthicum to assist an employee who felt faint.  While assessing and treating the patient, the paramedics were alerted to the possible presence of carbon monoxide by their CO alarm.  They immediately requested additional assistance to the scene and began to evacuate the patient and others in the area.
Additional responding units checked other areas of the hotel and found excessive levels of carbon monoxide in various locations in the hotel. Â Some levels were in excess of 700 parts per million- levels capable of causing serious injury with just two hours of exposure. Â The seven story hotel was evacuated by firefighters going room to room on each floor to ensure all employees and guests had been evacuated.
