What piece of information must be shown on an NFPA 1971 compliance tag inside protective clothing?

The requirement for the year of manufacture to be shown on an NFPA 1971 compliance tag inside protective clothing is essential for several reasons. This information is vital for ensuring that the protective gear meets the latest safety standards and performance requirements set by the National Fire Protection Association (NFPA). The year of manufacture allows fire departments and personnel to track the age of the gear, which can impact its effectiveness and safety.

Protective clothing, such as fire-resistant coats and pants, has a finite lifespan due to wear and tear, exposure to heat and flames, and potential degradation of materials over time. By knowing the year it was manufactured, users can better determine if the gear is still compliant with current safety standards and if it is within the recommended service life. This helps ensure that firefighters have the most reliable and effective protection while on duty.

The type of materials used is also important for understanding the protective characteristics of the clothing but does not indicate whether the gear is still suitable for use based on its age. Thus, the year of manufacture is a
