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 tunnel worker inside the Queens Midtown Tunnel, in Queens, New York, while the subterranean passageway was under construction. This man was manipulating the hoses on an unidentified holding tank inside the subterranean passageway. Note that the man was wearing a protective hardhat, but wore no gloves, or filtered breathing mask, though it cannot be determined from this image if these were necessary.
