Title:

This historical image was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH).

Description:

This historical image was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH). The photograph depicted a group of tunnel workers as they were emerging from a 'man lock' inside the Queens Midtown Tunnel, in Queens, New York, while the subterranean passageway was under construction. A man lock is an airlock which acts as an air pressure equalizer, allowing it occupants to enter from one pressurized environment, and emerge into an environment, which is under a different air pressure. Note that all these men were wearing hardhats, but none of the workers were wearing gloves, or filtered breathing masks, though it cannot be determined from this image if these items were necessary.
