The Robbinsville Township Fire Department tweeted early Wednesday that it was "on scene at Amazon Warehouse on New Canton Way investigating 'fumes' that have several employees complaining of illness. Fire Dept is attempting to isolate the source. EMTs are triaging multiple patients. 7 ambulances and a medic currently assigned."

The can of bear repellent contained capsaicin, which is found in chili peppers. The incident didn't require a complete evacuation of the warehouse, NJ.com reported, and it's under investigation.
