Err... That's a more difficult story.
There is no one way to do this and, as I see it, there is no 100% safe way. There is electron cash you might want to try. There's also a list of several clients that will accept bitcoin cash (although I'm not entirely sure what it is).

Edit: this is the link to a list of compatible wallets https://www.bitcoincash.org
You'll have to import your private keys/seed in the same way as you do in electrum into the desired wallet.
