Unfortunately economic interests usually trump common sense or social responsibility. Despite the clear health risks, there are still active mines taking asbestos out of the ground. There is a big one in Quebec. Their only markets are developing countries, as asbestos use has been banned everywhere else.Not hardly considering the pain and suffering it can cause. It's best if not used anywhere, especially in a country with poor access to health care.
You are correct that it is not being manufactured here but it is still being used as a roofing material..do not know where it comes from but in Higuey , my friends and I saw it being sawn by a man without a mask and put on a roof ,,It is lethal stuff when being cut or broken easily giving cancer of the lungs .It is an awesome building material. It is often used in roofing materials and tiles in a lot of countries. Dunno about the DR but it's pretty popular elsewhere in Latin America. Given the electrical system I'd say your increased chance of lung cancer is more than offset by the reduced chance of being killed in some conflagration
The average homeowner can't determine if their asbestos is harmless. If you have, or think you might have, asbestos in your home get it inspected by someone knowledgeable. Even if it's only roof panels. If it's friable or can become friable it should be encapsulated or removed. And that takes someone looking at it that knows what their doing. Don't take chances with it.if it is already in place it is harmless unless it is getting disturbed so don't get freaked out if you figure out there's asbestos in an existing building.
