  1. Hard Hat Safety

  2. A HISTORY OF HARDHATS

  3. A HISTORY OF HARDHATS • Manufactured by what is known as the Bullard Company today. • Called the Hard-Boiled Hat and patented in 1919. • Manufactured out of steamed canvas, glue and black paint. • 1938 - first aluminum hardhat became available.

  4. A HISTORY OF HARDHATS • 1940’s - use of heat resistant fiberglass. • 1950’s and 60’s - use of plastics replaced fiberglass. • 1980’s change in suspension.

  5. FIRST KNOWN HARD HAT AREA IN THE UNITED STATES

  6. HARD HATS • Must meet ANSI Standards • Require a hard outer shell and a shock-absorbing liner. • Have a liner that incorporates a head band and straps that suspend the shell from 1 to 1 1/4 inches away from the users head.

  7. HARD HATS MUST: • Resist penetration by objects. • Absorb the shock of a blow. • Be water resistant and slow burning.

  8. CLASSES OF HARDHATS

  9. CLASS A • General service only. • Provides good impact protection. • Has limited voltage protection. • Used in mining, building construction, shipbuilding, and manufacturing.

  10. CLASS B • Provide good impact protection. • Protect against high-voltage shock and burns.

  11. CLASS C • Offer limited protection. • Do not protect against falling objects or electric shock.

  12. SUSPENSION REPLACEMENT • Shows signs of deterioration such as cracking, tearing, or fraying. • No longer holds the shell from 1 inch to 1 1/4 inches away from the head.

  13. REPLACEMENT OF THE HARD HAT SHELL • The brim or shell is nicked, cracked, perforated, or deformed. • Loss of surface gloss. • Chalking or fading of surface. • Flaking of surface. • Shell is stiff or brittle. • Struck by a falling object. • Has made an electrical contact.

  14. DEGRADATION TEST OF THE HARD HAT SHELL • Compress the shell inward from both sides about one inch. • Release without dropping the shell. • Should return to its original shape quickly. • If elasticity is not similar to a new shell, it should be replaced.

  15. IMPORTANT POINTS TO REMEMBER • Protects from impacts from above. • Never modify the shell or suspension. • Avoid contact with electrical devices. • Replace if struck by a falling object. • Do not store in direct sunlight. • Do not sit on. • Do not paint. • Do not use solvents or cleaners.

  16. CARE AND MAINTENANCE • Remove head liner and inspect for defects. Replace if needed. • Immerse shell in hot water and detergent for one minute. • Scrub. • Rinse in clear hot water. • Inspect for defects, replace if needed.

  17. CARE AND MAINTENANCE • INSPECT DAILY BEFORE USING
