Title Estimation of CO exposure of road construction workers in tunnel
Bibliographic information Jan. 1997, Vol.35, No.1, p.119-125. Illus. 8 ref.
Abstract Carbon monoxide (CO) levels were measured in three tunnels in the Boston area (United States) and the potential exposure of construction workers in the tunnels was estimated. CO concentrations ranged from 5ppm to 42ppm, and a linear relationship between CO concentration and distance from the tunnel entrance was observed. The National Institute of Occupational Safety and Health (NIOSH) recommendation for CO exposure is 35ppm TWA for light work and 26-27ppm for heavy work. Repeated monitoring of CO levels during construction work in tunnels is recommended.
