The current COVID Risk Level is Low. Masks are optional indoors. Health symptom check required for site access.
When severe weather conditions develop (prior to the start of the normal workday) warranting the declaration of a weather emergency, the Laboratory will announce any changes to regular work schedules as early as possible, normally by 5:45 am via this webpage or the following:
Laboratory Telephone Hotline: (609) 243-2034
This page and the Telephone Hotline will be updated as soon as possible when there is an alteration in normal work schedules due to a weather or other emergency.
