1. What is Hard Hat Expiration?

Hard hats typically expire 5 years from their manufacture date, as recommended by OSHA and manufacturers. This accounts for normal wear and degradation of materials over time.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Manufacture Date — The date the hard hat was produced (usually stamped inside the hat)
• 5 years — Standard recommended service life for hard hats

3. Importance of Hard Hat Replacement

Details: Regular replacement ensures the hard hat maintains its protective capabilities. Degraded materials may not provide adequate protection against impacts or electrical hazards.

4. Using the Calculator

Tips: Enter the manufacture date (found stamped inside the hard hat shell) to calculate when the hard hat should be replaced.

5. Frequently Asked Questions (FAQ)

Q1: Why do hard hats expire after 5 years?
A: The materials degrade over time due to UV exposure, temperature changes, and normal wear, reducing their protective capabilities.

Q2: Can I use a hard hat past its expiration date?
A: It's not recommended. OSHA requires hard hats to be in good condition, and expired hats may not meet safety standards.

Q3: Where can I find the manufacture date?
A: Look for a stamp inside the hard hat shell, typically on the underside of the brim or inside the crown.

Q4: Are there exceptions to the 5-year rule?
A: Some manufacturers may specify different service lives, and harsh environments may require more frequent replacement.

Q5: What about hard hats that have been impacted?
A: Any hard hat that has sustained an impact should be replaced immediately, regardless of age.
