Does anyone know what #5 means for eye protection?

Its a certain type of goggle you have to have. Talk to your coach to get them. They should have some. If you don't have that type of eye protection, you'll be DQ'ed.

I believe #5 means high impact. If your goggles have "Z87" on them they are NOT high impact.
They need to say "Z87+" for Junkyard Challenge. Good luck.

From the official website:

5. High Impact Protection (ANSI Z87+)

Another attribute to be considered is Impact Protection. Protective eyewear bearing the mark "Z87" provides basic impact protection. Devices that meet the "High Impact" specifications of ANSI Z87.1-2003 are identified by the mark "Z87+".

High Impact protection is indicated when there may be a high inertia particle hazard (high mass or velocity). This will be specified in the rules by preceding the type of protective eyewear above 1-4) with the words "High Impact". e.g., High Impact Particle Protection Goggles or Spectacles.

People are talking about PLCs. But, are there any PLCs that work with only 6V? The ones we found require much more power.
