If a safety label reads PT 91, what does the 91 signify?

• A. The year of the standard with which the footwear meets compliance
• B. The size 9.1
• C. The model version
• D. The ballistic rating

Answer: (A)

The number following the safety footwear code shows the year of the standard the footwear meets. In this case, 91 indicates the standard as issued in that year, so the product is certified to that specific standard version. This matters because standards are updated over time, and a newer year can reflect updated tests or requirements. The two-digit year isn’t describing size, which would be a numeric shoe measurement, nor is it a model version or a ballistic rating. Those aspects would be indicated by different markings or codes elsewhere on the label.
