All the safety rules when using pillar drill?
They can be purchased in bulk for around $2. At a typical college bookstore you could expect to pay $3 to $6. For chemistry, you want splash-proof goggles so that there is no way for a liquid to get inside the goggles when they are tight against your face.
junior is incorrect, as is Elliot. Every helmet sold in the US has to have a DOT sticker, this means it has met minimum specifications for safety. DOT certifies every helmet sold, not just full face ones. Junior seems to think that the Snell sticker is better than the DOT one, and this thinking is flawed as well. About 2 years ago Motor Cyclist and researchers at a California university studied DOT only and DOT/Snell helmets and found that the DOT only helmets were better for your head. (See Blowing the Lid Off) in a past issue of MotorCyclist magazine. I've personally never heard of WOW helmets before, and I've been riding and wearing them since 1990. Next time, buy a well known brand, even if it costs a bit more. Your life could depend on it.
