SAFETY GLASSES (PROTECTIVE EYEWEAR)

Mechatronics Department safety rules* require that approved safety glasses be worn by every student in the classroom when appropriate.

The MECH 1 class requires the correct type of ANSI approved safety glasses (photos below).

Without the correct type of ANSI approved safety glasses, you will not be allowed to participate in any activity that requires them (e.g., hands-on activities, etc.) and may be required to leave the classroom during that time.  Activities usually may not be "made up," so you may lose the grade for that task if you didn't bring them.

Answers to some often-asked questions about safety glasses:

When will I first need safety glasses?

  • For MECH 1, safety glasses will be required by the second class session.


How often do I need to bring my safety glasses?

  • Safety glasses must be available to be worn every session.
  • Class schedules may change unexpectedly and a task that requires safety glasses may occur without advance notice.


Where are some places I can get safety glasses?

  • Hardware stores
  • Tool outlet stores
  • Building supply stores
  • The school bookstore
  • Big-box retail stores
  • Auto-parts retailers
  • On-line (have a shipping delay)


How much do safety glasses cost?

  • The cost of safety glasses can be relatively small.
  • A local "tool" outlet sells the "wrap-around" and the "over-the-glasses" types (see photos below) regularly on sale for as little as two dollars plus tax.
  • Wearing comfortable, fog-free safety glasses can be an important consideration, which may increase the cost.


How long do I have to wear the safety glasses?

  • Once an activity begins that requires safety glasses they must be worn continuously, even if it seems that they are not needed at that moment.
    • A nearby student may inadvertently cause something to happen that may be hazardous to your eyes.
    • Because the classroom is full of students who's actions may pose a risk, anyone not wearing safety glasses may be required to leave the room.
  • In our Mechatronics program, safety glasses are required and used for many hours of class time.  
    • Consider buying ones that are both comfortable and easy to see through (clear and don't fog up).


Are safety glasses available in the classroom?

  • No.  The instructor cannot lend you safety glasses.
    • This is due to cleanliness / hygiene considerations.
  • You're at your own risk if:
    • you borrow safety glasses
    • use someone else's
    • use a pair found in the room.


May I share safety glasses?

  • No.  You may not share the same safety glasses with anyone during an activity.
    • There must be one pair of safety glasses per student.
    • Passing one pair back-and-forth is not permissible.


May I use my eyeglasses, sunglasses or motorcycle goggles instead of safety glasses?

  • No.  Your eyeglasses, sunglasses, skiing and motorcycle goggles are not likely ANSI approved safety glasses.
  • They are certified safety glasses only when the lenses and/or frames are imprinted with the ANSI standard number, Z87 or Z87+.
  • Some cheap "dollar" look-a-likes that say "safety glasses" may also not be approved.
  • When in doubt, the instructor will check for that imprint.


What are the "correct type" of safety glasses? 

  • If you wear eyeglasses, the safety glasses must be made specifically for eyeglass wearers.
  • Goggle-type or over-the-glasses type safety glasses must be used by eyeglass wearers (see photos below).
  • Safety glasses intended for non-eyeglass wearers may not be used over or under eyeglasses.
  • Approved safety glasses must have clear lenses.  
    • Unless there is a medical reason to use them, dark lenses will not be allowed for safety reasons.
  • If you are in doubt about a purchase:
    • ask the teacher
    • be sure to save the receipt and packaging for a possible refund


What does "ANSI approved" mean?

  • Safety glasses must conform to a higher standard of impact resistance than regular eyewear.  That standard applies to both lenses and frames.
  • OSHA, the federal government department that oversees workplace safety, has adopted safety-glass standards established by ANSI (the private, nonprofit, American National Standards Institute).
  • Safety glasses must pass a high mass impact test, a durability test and, for the high impact rating, a high velocity impact test. 
  • Non-prescription safety glasses are marked with either Z87 (basic impact) or Z87+ (high impact).

*"Personal protective eye wear conforming to ANSI Z87.1 must be worn by every student in the classroom any time there is a potential hazard that could adversely affect a person’s eyes and/or face.  You must furnish your own eye protection which can be purchased at an automotive parts retailer, hardware store or from the campus bookstore at a nominal cost."
