Caveats:

Safety Glasses: Safety glasses with side shields are required to be worn during lab activities associated with this course. This requirement complies with accepted eye protection practices and Kansas State Law (K.S.A. 72-5207).

Safety glasses must meet American National Standards Institute Z87.1 specifications. Safety glasses brought to lab and worn will be part of the lab grade. Failure to bring safety glasses to lab will result in the students being dismissed from class until they have safety glasses.

Note: Most prescription eyewear does not meet ANSI Z87.1. Students who wear prescription glasses must:

  1. provide evidence that existing eyewear meets ANSI Z87.1, or
  2. wear cover goggles (if allowable), or
  3. purchase and wear ANSI Z87.1 prescription eyewear.
