Narrative:

I did not notice certification sticker was out of date maybe because certificate sticker is not same color as all our certificate stickers in shop and is certified for 5 yrs. My foreman caught certificate sticker out of date. Units were pulled from service. Out of date units were sent to standard laboratory for certification. I think all our certificate stickers should be same color and easy to read.
