I have asbestos shingle siding on my house. It is currently covered up with vinyl siding. Is this safe to nail into... break up.. I am not drilling, sanding, or cutting with any type of saw... when I come acress it for various reasons, I snap it off carefully. Is there any danger in this removal technique? What is the proper procedure for disposing of these shingles?

From what I have read on various sites you can throw away small amounts in your garbage
asbestos waste does need to be separated
from other waste and to fit in a 1m x 1m container
and sealed or contained as explained below
anything 50 lbs or over needs to be transported to a hazard waste site

Here is the California guide for disposing
I don't know if it is stricter or the same for other places.
Asbestos wastes must be contained and transported in one of the following ways:

1.In sealed, leak-tight, and non-returnable containers (e.g. plastic bags of 6mm thickness, cartons, drums, or cans) from which fibers cannot escape. Wastes within the container must be adequately wetted to prevent blowing of fibers in case the container is broken.


2.For bulk wastes that will not fit into containers without additional breaking, place wastes into sealed and leak-tight wrapping after wetting. If the wastes are to be placed directly in trailer or drop-boxes, the trailer or drop-box should be lined with plastic sheeting. The wastes should be wetted to prevent blowing of fibers in case the wrapping is broken. The wrapping should be sealed (e.g. with duct tape), and the trailer or drop-box should be covered with a tarp.

In California, asbestos wastes totaling more than 50 lbs. must be transported by a registered hazardous waste hauler to an approved treatment, storage, or disposal facility. Persons generating and transporting less than 50 lbs. of a hazardous waste to a permitted hazardous waste facility are exempt from this requirement and the requirements concerning possession of the manifest while transporting hazardous waste upon meeting all of the following conditions:
1.The hazardous wastes are transported in closed containers and packed in a manner that prevents the containers from tipping, spilling, or breaking during the transporting.


2.Different hazardous waste materials are not mixed within a container during the transporting.


3.The person transporting the hazardous waste is the producer of that hazardous waste, the person produces no more than 100 kg of hazardous waste in any month, and accumulates no more than 1000 kg at any one time

Most of the danger from asbestos is when it becomes friable and repeated exposure. I do not think you are in any hot water but I don't encourage folks to do anything to asbestos other than encapsulate it.

Yeah they say if it is in good condition to leave it alone as much as possible but I guess in his case he needs to repair/redo his new siding.

Nailing through should be fine. If you nail through it, it will break. Where I am, asbestos siding is no longer considered hazardous waste, goes to county dump.

Imagine that. Lead paint scares, Ever wonder about Gov not mentioning drinking water through a water line with Lead solder in it...

Or fish is bad for you because of the mercury in the water but we can put mercury in your teeth to fill a cavity and in the CLF light bulbs.
