Dear Kaylan
you will find some documents on SCN and on SAP help etc. pages as well as SAP marketplace regarding your "doubts/questions" (bnut not easy fo find "good" ones); there are some OSS etc. which "talks" about use of S/4 HANA and EHS/EHSM.; some EHS classic components are not supported in S/4 HANA (check OSS notes !)
But as Pavan explained: this is very strategic decision; as well other options exists as "on premise" etc. solutions.
Coming back to your doubts:
What are the integration capabilities on S4 Hana 1511 with SAP EHS Central Repository.
=> if you have an S/4 HANA installation you can use EHS/EHSM (according to what I have read sofar and learned as well) in one system
RegardinG:
If there is a separate SAP EHS central repository which interfaces with multiple Logistics system and S4 Hana 1511 will be used as a primary ERP for all those Logistics system in future.
=> this is more complex.... S/4 Hana is "normally" the follower of SAP ERP. So I am not sure: why do you would like to use on S/4 HANA installation and many parallel SAP ERP systems?
IN any case: according to my knowlegde: whatever scenario you look for: as longas ALE is the same you can use EHS classic and exchnage data between several SAP installations
=> Which is the better way to go ahead to implement Product Safety and Dangerous Goods?
no clear answer is possible: Any SAP EHS installaiton will take some time and deciscions are needed (e.g do I use contetn etc.)
may be checke.g. Some links: SAP S/4HANA 1511 On-Premise Roadmap

PS: i have reread your sentence:
If there is a separate SAP EHS central repository which interfaces with multiple Logistics system and S4 Hana 1511 will be used as a primary ERP for all those Logistics system in future.
This is not a good approach. You would stick with EHS on one system and any logistic part on S/4 Hana; but as we know: you must integrate.
Reasons are like:
MSDS dispatch
SVT
GLM
and many others
Therefore this is not a good option..
As Markl has explained: becuase of many reasons: SAP ERP systems are reduced if possible; if you have onEHS installaiton and one SAP ERP you may be should move EHS installation to SAP ERP.
There is currently only one reason for EHS classic to stay in one system: the "low" performance of EHS (mainly EHS-BD);
For EHS classic there is as well a sizing guide available. (so caleld "T shirt sizing);
May be check as well:

As well check SAP S/4HANA | SCN
