What are safety goggles (In labs) made of?

Glass or perspex(plastic).Each have their advantages and disadvantages

They are all different materials (plastic polymers)that contacts are made out of.  Etafilcon A is what Acuvue and Acuvue 2 are made of.  Phemfilcon A is FreshLook and ocufilcon D is 55.  Each material is made by different companies and does essentially the same thing.

You can describe different types:\n\nhttp://www.aecom.yu.edu/ehs/Industrial%20Hygiene/Fs_Fibergls.htm\n\nhttp://www.clarkcraft.com/fiberglasscovering.php3

refer to your OSHA manual or talk to your safety supervisor. You can always contact OSHA at www.osha.gov for more info.  I recommend OSHA approved Z81 frames with permanant side sheilds. As for the lenses at least 2.0mm Center thickness lenses...DO NOT USE POLYCARBONATE if you are welding

Wild guess here... a dihydrate of copper chloride.\n\nSecond guess would be copper sulfate, possibly from the manufacturing process.

Sadly, many animal rights groups would lead you to believe that animals are exposed to anything and everything. In reality, any compound intended to be used on human skin is extensively tested in labs prior to being tested on animals. They check everything from basic corrosive properties to chemical interactions. Scientists are not out there spraying concetrated Nitric Acid into rabbits eyes out of curiosity.\n\nThe actual animal testing is done only if they already have a resonable expectation that it would be OK. Further more, once animal testing is done, they also do human testing as a final verification prior to gaining approval for public use.

silicone, carbon, nitrogen, sulphur ect. basically eny  elements from grp 4 - grp 7, all group 3 elements r amphoteric( both acid n base) n grp 1 n2 oxides r basic

I think its bcoz of some lyophobic particles present... im not sure..... jus guessin...

The best way to keep your goggles fog-free is to keep your lenses clean. Start with clean lenses by washing them out with dish washing detergent or shampoo. This will remove the body oils in your lenses. After your swim rinse the inside of your lenses out (not with your fingers, unless your using shampoo), then dry them off with a soft, clean towel. This should help to reduce fogging. The anti fog solution in stores work to an extent but I'd rather just keep my lenses clean than to spend 5 bucks.

http://ohioline.osu.edu/~agsafety/ash/programs/osha_labs.html\n\nYes, there is.\n\nCompliance with the Laboratory Safety Standard was initiated for the College of Food, Agricultural and Environmental Sciences Columbus campus in June, 1998. This standard applies to all departments that deal with wet chemistry on a laboratory scale i.e. operations easily manipulated by one person, large number of chemicals, small quantities of material, multiple procedures used, not part of a production process, etc. Compliance is similar to that for the Hazard Communication Standard with some additional requirements. The following outline should assist you in complying with this regulation. Please call the college safety office if you have any questions or require any assistance. \n\nRequirements and What to Do \n\nWritten Chemical Hygiene Plan \nObtain generic Chemical Hygiene Plan from OEHS at http ://www.ehs.ohio-state.edu/index.asp?PAGE=ehs.chp, or the college health and safety speacialist, follow instructions, add sections and fill blanks, modify if necessary. Locate your written Chemical Hygiene Plan in a place accessible to employees. \n\nChemical Information \nInventory chemicals and obtain MSDS's for those with hazard ratings of 4. Locate MSDS's with Chemical Hygiene Plan. Post inventory on laboratory door. Provide access to and identify sources of chemical information.Retain labels on chemicals received. You may search for MSDS's at http://www.ehs.ohio-state. edu/. \n\nTraining\n\nIdentify and list employees required to have training. Send laboratory supervisors and employees to OEHS or the college health and safety speacialist for generic lab standard training.Train employees on special procedures for handling laboratory chemicals.Document training.

Well, lets see ... there's plastic, steel, and nylon for sure.  \n\nAnd possibly ...adhesives, polystyrene, paint, glass (this one's a little iffy because it does occur in nature, albeit infrequently)

Toothpaste.  Smear it on the goggles then rinse off with cold water.  Also helps with eyeglasses that fog. How I know that I will never know!?! =)

I don't know medically important examples, but nitrocellulose (gun-cotton) is made from nitric acid and cellulose (like from cotton).  I think the nitro-groups replace the OH groups.  The resulting product is an explosive (it can burn without oxygen because it has the required oxidizing groups in the molecule.\n\nThe sugar substitute sucralose (Splenda) is made from sugar where a lot of groups are replaced with chlorines.

Louis Garneau used to have 10% recycled materials in his helmets, Not sure about nowadays but won t hurt to check into them.\n\nheres a cool one>http://www.nytro.com/product_p/22044.htm

There are two ways that I am familiar with and that are safe.  One is anti-fog gel made especially for divers and snorklers.  Its somewhat pricey depending on where you live.  The other, believe it or not, is toothpaste. take a small dollup on your fingertip.  You dont NEED alot.  Then rub it on the inside of your googles so it makes them white and filmy.  Let it dry, and then rinse and wash them off.  It works.  If you use too much it will bother your eyes as will the anti-fog gel so DONT OVER DUE IT. If you want to try it on your bathroom mirror when you shower the next time feel free.  Follow the same steps.

Well.. It sounds like your a teacher, aren't you?\nHmmm... according to "good laboratory practice", everyone working in the lab are required to wear a lab coat. It's not suppose to be an uniform, but to protect us from any dangerous chemical spillage.\nIf concentrated acid (E.g. 10M) is spilt on your labcoat, you can just take it off and discard it. But if the acid is poured directly to your shirt, I guess you would have to take it off as you lack the extra protection of the labcoat.\nIf you are working with volatile chemicals (ethanol, chloroform, phenol, concentrated acid etc.), you are suppose to work with the chemicals in the fume hood and not in the open space, as the fumes of such chemical can cause respiratory disorder, eye irritation, etc.\nPlease refer to MSDS (Material Safety Data Sheet) available from chemical supplier and online.\nNormally for student's lab experiments (Secondary or Pre-university), the chemicals involved are common chemicals that are not very dangerous if handled properly. Acid and Alkaline used are also very diluted (0.1M-0.01M), which don't really cause much of a damage to your clothes or skin if you wash it off with water quickly.
