Is it safe....?

to live un the vsame room as gas tank and water heater of home in basement? the gas tank is not in a completely enclosed closet. the door to the closet is a shutter door. Basically the gas tanks ventilation goes into the basement, thats it's out source (the same basement i live in).
Also, my husband and I have been getting headaches and every morning my baby's nose, as well as my husbands and myselfs nose are super stuffy and congested.
Are we safe down here or could we be getting carbon monoxide poisoning?
Serious answers please.
Thanks

it is not safe at all.
about the carbon monoxide poisoning...it is not the case!this is the result of burning the carbon in oxygen at hight temperature.what is happening there is the exposure to gas inhaling,only and hazard of fire
will copy for you some things from wikipedia to see what could happend ,first of all to your health:
Solvents and propellants used as inhalants are found in a range of inexpensive, legally-available household, office, industrial, and automotive products. A number of household and office products contain solvents that are used as inhalants, such as toluene and acetone. These products include correction fluids such as Liquid Paper, nail polish removers (acetone), and permanent markers (xylene).

Propellant gases used as inhalants in household and office products include freon and compressed hydrofluorocarbons, which are used in various household and office products that come in aerosol spraycans, such as air freshener, computer keyboard cleaner spray (canned air), non-stick cooking spray, aerosol insecticides, and aerosol hairspray. Another household product which contains propellant gases that are used as an inhalant is aerosol whipped cream cans, which contain nitrous oxide gas.


Industrial and automotive products also contain solvents and propellant gases that are used as inhalants. Solvents such as toluene are found in turpentine, gasoline, paint, spraypaint, an a range of quick-drying adhesives and cements (e.g., rubber cement and plastic cement). The solvent diethyl ether is used in an aerosol product called automotive starting fluid, which is used to help carburetor engines start in frigid weather. Canisters of butane are used in inexpensive home welding kits.

if you have this symptoms,get someone to fix the closet's door,or move to another place.sorry if i am not giving you the expected or very helpful answer

Get a carbon monoxide alarm/detector, if it goes off then leave the basement immediately and call the fire department

erm... It doesn't sound safe at all.

If I said I lived in the same room with a huge, fiery, explosive tank next to something that generates HEAT of all things... wouldn't you look at me a bit weird?
