Any flammable gas is hazardous to your health if used improperly.
Some points:
Working in your kitchen is not a good idea. This is a food preparation and eating area, not a glass fabrication area. Glass bead making and food do not mix.
Working beside an open window is not good ventilation. You need some method of capturing contaminated air and moving it outside as well as replacing the exhausted air with fresh air from outside.
You can have no more than 2 (two) one-pound bottles of MAPP (or propane) in your residence at any given time, including a garage if it is physically attached to your house.
Gas cannisters must be disposed of properly, this usually entails removal of the filling orifice on the bottle and allowing any remaining fuel gas to leak out (this should always be done outside), or calling your local waste hauler to find out the proper method of disposal of the tanks. They may tell you that they will not accept them as part of the household waste stream, that they are considered hazardous waste and must be disposed of separately - if they do tell you that, ask them what the method and procedure is. Don't allow a bunch of "empty" tanks to lay around your house or garage.
This is basic safety information that is covered in a variety of threads here at LE and elsewhere, as well as many of the books and videos, and should be part of almost every beginning lampworking class taught.
For your future studio, you mention that you will have an oxygen and gas tank. Please be aware that the gas (fuel gas) tank MUST be kept outside at all times. Please read the "Propane in the house?" thread:

I would also strongly encourage you to do some reading of the many ventilation threads here on LE and elsewhere.
