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

You can find international suppliers at the reference.  It appears that many materials are used including plastic and aluminum.

they give you glasses to wear for boot camp so you dont have to worry about having a lense pop out or get dirt in it.  Trust me you will spend a good amount of time in dirt, or sand.  You dont want you glasses or contacts going through that.  Use their glasses, they are free and you dont need to worry about them breaking.  Once a year the corps will give you a free pair of "civilian" glasses, they are actually a nice pair of glasses, but you dont want them in the field.

Try looking at a substances MSDS.  That is Material Data Safety Sheet.  If it is a pure substance that will be helpful. Just put the name of the substance and MSDS into yahoo and you'll find a sheet

What kind of "safety"?

Stained glass makers use 60/40 solder, which means 60% tin and 40% lead, has a lower melting point so it doesn’t require as much heat. \n\n--> http://www.delphiglass.com/soldering-items/solder/mastercraft-60-40-solder-1-lb.html

probably not much more than spectacle frames can kill you through metal poisoning

Because the silicon chip inside is light sensitive, so they need opaque casings to keep from stray light from interfering with the proper operation of the device. Some light sensing chips are made with a clear epoxy body and a molded-in lens.

it depends on the material, you could have FCC, BCC, HCP and many other crystal structures, with many different substances present dependent on the alloy

why do you need it?  how much do you want to spend to figure out what it is, or what alloy it is. \n\nyou can just do the density measurement\nmeasure the radius of the wire and length. \ndo the pi r squared length deal and then weigh it, and run it through the density equation. \n\nyou need a ruler and a calipers or micrometer that reads in inches. \n\nso lets say you have .125 inch wire.  divide that by 2 to get the radius. =  .0625"\nthen square it.  .0039" and multiply by 3.14. \n\nand multiply it by the length in inches  \n\nthen weigh it.  in lbs. \n\ndensity of al is between .096 lb/cu in. and .100 lb/cu in\n\nyou might want to buy wire that is certified as the type of aluminum you need.  the stuff is cheap.  you can get at the electical supply store or maybe a hardware store. \n\nwiring used for electical applications is 8000 series alloy for modern applications \n\nolder wire is 1350 alloy.

Because the incident angle is fixed at 60 degrees, ordinary optical glass (refractive index of 1.52) is not able to support total internal reflection, and a prism having a high refractive index is required. Prisms fabricated with flint glass (refractive index of 1.64) will meet these specifications, and are commercially available. The beam will then refract away from the normal at an angle of 69 degrees in passing from the prism into the coverslip, thereby exceeding the critical angle at the coverslip/buffer or coverslip/cell interface. A trapezoid with walls ranging between 45 and 60 degrees is ideal, but these units are not readily available and must be manufactured to custom specifications. Unfortunately, 45 or 60-degree trapezoids are also not commercially available, but they can be cheaply produced by truncating and polishing the apex of a commercially available triangular prism.

is this a question about being a pilot? if not the only thing that matters is that your vison can be correceted to 20-20 or close to it with glasses.\n\nmsg me if you have more questions
