to muc bad intake of air for example a factor to smoking , inhaling petrol fumes or even fart gas
You waft it toward your nose with your hand, which dilutes the fumes in the air, preventing you from inhaling too much of a potentially harmful substance.
If you inhale 'air' from your nose, you are more protected from nasty tings in the air because your nose hairs catch everything bad (or most of it), and gives you the 'clean' air. This is also how 'boogers' are formed :)
The majority of risks when it comes to using an inflatable mattress focus around children more than adults. Some air mattresses can give off toxic fumes which are harmless to adults but dangerous to children.
Inhaling.
Probably not - I've never heard of it. I've heard of miscarriages being caused by breathing paint fumes - but the ones that say low odor are safe.
Fumes are colloidail systems (solid-air or liquid-air).
Thorium metal cuttings may ignite spontaneously if exposed to air. Extremely flammable; will ignite itself if exposed to air. Burns rapidly, releasing dense, white, irritating fumes.
Inhaling
yes it is dangerous for the environment because rocks may fall of a Cliff and kill something and quarries can also cause air pollution which is gasses and fumes building up in the air to make a smell that could kill something...
The force required to open air bags is dangerous for children, infants, and small adults.
A vent pipe is located afte a fixture trap to remove dangerous fumes from the system and exhauts them through the roof terminal as the fresh air enters through the fresh air inlet
