I don't think it is so much a matter of safety as of other issues. The area is enormous and very densely populated. I would probably have gotten completely lost and, if that hadn't happened, at best I would have found a fraction of what our guide showed us. He also clued us in as to what was culturally appropriate for us to do, especially limits on appropriate photography. Personally, I wouldn't take children under the age of about 13 or 14, not so much because of safety as because of cultural shock.

Yes! .. I can recommend Magical Mumbai Tours.. I used them specifically for this exact tour.. They are great!

Mumbai magic can connect to Dharavi and arrange transportation to and from as well as other sites. I don't think it is a full day tour but maybe you can add Dhobi Ghat and some other sites through Mumbai Magic?

We didn't take our kids but there were some people with kids around 7-9. I think it would be excellent for them. Just wear closed shoes! We stepped through dirty water, dead rats and possibly human waste! However, the experience is worth it and would be invaluable for kids. My little one was 3 which I felt was too young.

Hola, it's not dangerous but I would not recommend it. Dharavi is huge and you need some explanations. If you are a man and your Maharati , the local language,is good you can ask for the way. Reality Tours are really good.
