You should hold your hair dryer 6 to 8 inches away from your head for optimal results and to avoid too much hot air near the scalp.
A CHI hair dryer uses ceramic technology that can dry hair up to 40% faster. They also contain far infrared technology which is a lot safer for the environment and also results in a reduction of EMF (Electric Magnetic Fields)
It is very dangerous to use an electronics in a room where there are gas generators. It is recommended that you use an electronics far away from gas generators.
Compressed air. Most people have to use cans of air, but I have an air compressor with an air dryer on it. It will blow FAR more dust out of a computer than a can of air will.
Usually up to where you grow hair.
Commercial or residential and what manufacturer
Jump to the top of the bathroom counter. Then jump on top of the hair dryer and tilt it as far up as you can without it falling of. Jump on the buttons and the hair dryer will turn on. Get into the air flow and it will blow you to the top of the curtain rod. Keep walking and you will fall onto the bathtub soap rack. Push the soap off of the rack. Jump down. Try jumping out of the bathtub to your left and you will find you can't get out that way. Climb up the plug rope and start the bath. Jump onto the the soap and you will be able to jump to the side of the bathtub where you can jump off and be in the toilet zone.
far hair
Jump on the back of it and point it up as far as possible. Then press the red button and ride on the air flow, up over the shower curtain into the tub. (You are going there to flush the thumb drive, but you have to back it up on the computer first.)
Nominal residential voltage is 120/240 volts. Not sure from you description if the plug is just rated at 230 volts or is supplying 230 volts (It is likely that the plug may be rated at 230 volts, but only operating at 120 volts). A typical hand held hair dryer would operate on 120 volts. A commercial hair dryer might operate at 220 volts, but must be plugged into a 220 supply.
There is no requirement on the distance the dryer must be from a sink. Any 120 volt outlet must be GFCI protected if it is within 6 feet of a sink. There is no requirement for a 240 volt dryer outlet. I would not want the dryer right next to the sink and I would want the dryer to be on a 4 wire circuit and not a 3 wire circuit. Use common sense here.
One should work far enough away from the flame to avoid contact with the flame itself. A person should have enough distance from the flame to keep loose clothing and hair safe as well.
As far as I know, you can't. It would be safer to have a new outlet installed closer to the dryer.
