![]() ![]() The first sign of CO poisoning from exposure to higher levels (over 100 ppm) is usually a headache. PANY & NJ varies the air ventilation in the tunnels depending on traffic flow.Ĭurrently, there are no generally recognized health effects from breathing CO at the levels seen in the survey. CO exposures to toll collectors have decreased over the years as vehicle emissions have decreased and ventilation has increased. We don’t know if this represented a routine exposure. One of the samples was higher than the OSHA PEL for peaks - 372 ppm. ![]() One of the samples was higher than the OSHA PEL for peaks - 229 ppm. OSHA does not have legal authority over the PANY & NJ because it is a state agency, but PANY & NJ voluntarily complies with OSHA regulations. NIOSH’s recommendations are the same as OSHA’s legal standard. ![]() Exposures may not be over 35 ppm averaged over 8 hours and may never be over 200 ppm. The Occupational Safety and Health Administration (OSHA) has two permissible exposure limits (PELs) for CO exposure. The average peak is the average of all the peaks recorded over each shift. Highest 15-minute average: the average of all the highest 15-minute concentrations recorded during each shift.Īverage peak: “peak” means the highest concentration recorded for an air sample. Range: the lowest and the highest concentration of CO for each shift The range is shown for three measurements: 1) the average over the shift, 2) the average over 15 minutes, and 3) the average peak. For example, 1 ppm of CO means 1 “part” of CO for every one million “parts” of air.Īverage level over shift: the concentration of CO averaged over the work shift. Ppm: “ppm” means “parts per million.” It is a measure of the concentration of a substance in air. NIOSH took air samples of carbon monoxide (CO) for a health study on the effects of CO exposure. *** Compare to the OSHA peak (or ceiling) limit of 200 ppm. ** Compare to the OSHA permissible exposure limit ( PEL) of 35 ppm over an 8-hour workshift. (The concentration of CO inside the George Washington Bridge booths, which are ventilated, was about 75% lower than the concentration outside the booths). The concentration of CO inside the unventilated booths was about 16% higher than the concentration outside the booths. All work is being performed on a lane by lane basis while keeping the existing system operational.Table 4: Goethals Bridge – Toll Collectors Work Devices include Vehicle Enforcement Cameras, SICK Overhead Vehicle Sensors, LEC Lane Controllers, Lane Messaging Signs, AVI Antennas, toll booth canopy conduit, toll island concrete replacement, and new Close Up Lane Observation Cameras. ![]() This contract includes the electrical reconstruction of 66 EZ-Pass lanes, including the replacement of the most ETC components.
