TRENTON - Tests at dozens of Hurricane Sandy cleanup sites show that the level of contaminants does not exceed federal workplace exposure limits.

The tests were done by the Occupational Safety and Health Administration (OSHA), and the sites in New Jersey and New York will continue to be monitored.

While some of the sites showed the presence of contaminants including asbestos, carbon monoxide and lead, none were above OSHA's permissible exposure limits.

The sites will continue to be monitored. The agency warned that the results aren't an "all clear" to employers.
