Risks and opportunities in ISO 14001:2015

Dear Strahinja, To give you a little background, we are a small electronics company with approximately 120 employees. We have been working to implement ISO 14001:2015 for approximately 6 weeks. We already were compliant with ISO 14001:2004 version. We are planning to have our first NSF audit 7/17/17. I believe that most of the 14001:2015 requirements are being covered but we are still very confused on Risks. I have read multiple white pages but I haven't seen an actual example of an environmental Risk. I decided to utilize our APQP risk assessment form because it is very similar to others I found on the internet. But when my team sits down to discuss what a Risk is, I struggle to be able to explain it. We already have a list of aspects, so do we utilize the aspect list to create potential environmental problems that become our Risks or are Risks something we invent? For example, there is a fire and the fire reaches our stock of different types of plastic, burning it and creating dangerous smoke that pollutes the air. Would this b e one Risk? If so, then do I sit the EMS team down and invent multiple Risks that our processes could create if something major happens in the facility? Any help is greatly appreciated. Thanks
