No, not all vermiculite contains asbestos. You should have it tested.
Asbestos was not an intentional component in vermiculite, it was a contaminant in the material as taken from the ground. The only way to "quit using" it was to stop using vermiculite fro those sources.
I believe a good salary for a insulation contractor would be around $60,000.00 per year, due to the physical labor and health risks that they sometimes incur.
Vermiculite insulation containing asbestos is about as dangerous as any other type of insulation that contains asbestos. If it becomes airborne and people breath in the fibers, their risk of contracting an asbestos related disease increases. The amount of increased risk depends on how much asbestos is in the insulation, how much becomes airborne, how long the people are exposed to the airborne fibers, and whether they smoke tobacco products.
Yes, it is fine to do that. You should also put the batts perpendicular to the rafters. This will help tp minmize thermal bridging.
Currently it is illegal to add insulation to a home with more than a very small percentage of asbestos. Exposure to these small quantities of asbestos typically do not cause harm and are considered to be safe. Older homes may have asbestos insulation that needs to be removed as these older forms of insulation do present certain health risks.
Vermiculite has many uses. One of the typical things it is used for is seed germination. It also is used in brake linings, loose fill insulation, acoustic panels, as a soil conditioner and a additive to fireproof wallboard just to name a few things.
It's about 25mm - 1" vermiculite thick layer for every 100 degrees Celsius temperature level. For 350C oven temp reach the insulative layer should be 70mm thick.
