I did approx 600 ft in my kitchen.
I covered all cabinets and counters in plastic sheet and taped off. I also made plastic barrier curtains between the other rooms.
I then wet the tiles down with a combo of water and soap from a pump mist bottle. then I used a floor scraper (Floor Bully from Home Depot
http://www.qpitools.com/QPIProductFloor.htm) to get the tiles up and placed them in construction grade hefty bags. I used a flat file often to keep the scraper edge both clean and sharp.
When the entire tile didn't lift in one piece I used a hammer and putty knife to remove the remnants....while wetting with the mist.
The problem arises when the tiles crack and their dust gets into the air.
I wore tyvek coveralls, respirator and nitrile gloves taped at the wrist. When done all plastic was carefully folded and thrown using the hefty bags.
BTW, most 9x9 and 10x10 floor tile sold today contains asbestos...as does Spackle and other joint covering products.
