content: Hello ! I want to ask You How safe is to use infrared tools ? I own an infrared preheaterBest 853A chinese brand, and it makes me hard headache every time Im near of it. whenever I approach this infrared heater only for a few seconds, I feel it burn my head and occasionally has lasted me several days the burning sensation inside my skull, i think can be the low quality brand or what ? I cant work onto it

content: Could be the initial fumes from whatever coating is on the heating elements from factory.If so it may go away once it's all burnt off.Installing a fume extractor funnel right above the unit to pump the air outside may help also.But really, if your body is saying "GTF away from that" you really should listen to it.

content: thanks, But its Not about the fumes, is a strong heat radiation emitted by the device that I dont know if its normal on other brands

content: Quote from: mrflibble on August 04, 2013, 03:06:47 pmNo, it was a few IR hotplates. The operators were issued with special dark glasses to protect their eyes but everyone that used them suffered with dry eyes so although they did an excellent job of heating, the risk if causing real damage to the operators left them useless. I wonder if it's the same mechanism causing problems.

content: It is definitely not a good idea to look directly at a powerful IR source just as it is not a good idea to look at the sun. I cannot think that there is any emf that causes headaches so it must either be the IR which perhaps it pulses at a frequency that you are susceptible to or its the fumes from the unit. If its flashing IR or light I would also avoid any strobe lights and also get a medical check it just might be you have a predisposition to epilepsy and you certainly don't want to bring that on.

content: This is very funny question. Its like asking why the sun is hot. That's because IR brings heat and you eyes is not able to fully see the IR wavelength so you can either mask the exposed areas with alu foil or return it with a non IR preheater.

content: Some of you took it as a joke, but I suffered internal burns in the skull, I exposed only about 15 seconds to preheater at a distance of 40 cm, the device was only 220 degrees Celsius, and I spent several days recuperating from that, so I think that device is dangerous to health and just wanted to alert you that!I also wanted to know if others have had similar symptoms of burns with infrared preheaters in order to know if its the quality of the brand or its normal in all infrared tools.should be noted that this preheater does not emit light, but only infrared heat. so I had no problems with sight, only burns.I work with mobile technical service. and preheater is very necessary for this work, now I'm making a resistance based preheater which emits no infrared heat

If you "suffered internal burns in the skull" you would likely not be here to tell that bullshit story.Listen, you got a device that is supposed to heat up things you put above it. You put your head 40 cm above it. And you are surprised it got hot? Doh.

For Christ's sake, yes, infrared heaters emit infrared. And in other news, knives are sharp, soldering irons hot, water wet. I think you suffered the internal skull burns a while ago...

content: Things heat up for two types of reasons: 1). heat transfer or other types of energy to heat conversions.The examples of the later are microwave oven, or current flowing through a resistor. They are done by converting other types of energy to heat.On the other hand, heat transfer is the exchange of heat energy from hotter objects to cooler objects. It is done by conduction, convection, and/or radiation.IR is the radiation part of the story. It is not the whole story. Though, heat transfer will be always associated with IR to a degree due to the heat source being "hot" (Black body radiation), it does not mean different heating methods have the same contribution from radiation (IR).

content: HeyOP:Firstly I really sorry to hear you got harmed ...secondly : No matter the cause .. either reflection of few of the beams by metallic cases ( shields .. Solder traces .. Crystals .. Etc ... ) .. or some problem with the device himself ...you must know the Hazardous caused by the device you got .I welded one day with no sleeves .. and when I went into shower .. well .. I felt like my shoulders was sunburned .. that's due to ultra violet and perhaps Infra red as well ..*Yes I had long leather welding gloves . and auto shading welding mask . and long pants plus leather welding apron and ?hoes with protective cap ,No dizzy , no headache no nothing .... because I was aweary of the potential of blinding . and perhaps even worse stuff ... I used the proper protection wear .for you ... I'd go ahead And build some shielding ... simply Hermetically siled box with front door ... and nice stickers to warn the workers ...eyes are not proper light shading tissues ... IR radiation can fry your poor little brain .. that's some serious Hazardous to be awear of ...I was going to say that need to be sticky thread ... but nope ... that's not the correct form of doing that .... if someone know how it should be done ....it would be nice if you share it
