How Should You Inspect a Hard Hat Before Each Use?

Hard Hat Inspection: Common Questions

How often do hard hats need to be inspected?

A hard hat should be visually inspected before every shift, not just once a month. OSHA's general PPE duty of care under 1910.135 puts responsibility on both the employer and the wearer to check gear before use. Beyond the daily check, many safety programs log a more thorough hard hat safety inspection weekly or monthly, especially for crews working outdoors in direct sun or around chemicals.

Is OSHA changing hard hat requirements?

OSHA itself references the ANSI/ISEA Z89.1 standard rather than writing separate helmet specs, and that ANSI standard has been updated over the years. There's no federal mandate forcing crews to switch to climbing-style helmets, but many contractors are moving that direction voluntarily for better coverage and chin-strap retention. Always check the ANSI date stamp inside your hat and confirm it matches current Type/Class needs for your jobsite.

What color hardhat do inspectors wear?

OSHA does not require specific hard hat colors, but many jobsites adopt informal or company-specific color coding. White is the most common color assigned to supervisors, engineers, and inspectors, while orange or yellow is often used for general laborers and green for new hires or safety officers. If your company uses a color system, confirm it in your site safety plan since it's not a universal OSHA rule.

Do hard hats expire under OSHA?

OSHA doesn't set a hard federal expiration date, but manufacturers do, and that guidance matters during any hard hat inspection. Most shell manufacturers recommend replacing the shell every 5 years from the date of manufacture (stamped inside the hat) and replacing the suspension every 12 months regardless of visible damage, since UV exposure and sweat break down the plastic and webbing faster than they show on the surface.

What should I check on the hard hat shell before each shift?

Run your fingers over the entire shell feeling for cracks, dents, gouges, or soft spots. Hold it up to light and look for a chalky, faded appearance, which signals UV degradation even if the shell looks intact. Check the brim edges for fraying or cracking, and confirm there are no unauthorized holes drilled for stickers or accessories, since holes compromise the shell's structural integrity.

How do I inspect the suspension system inside my hard hat?

Pull each suspension band and check for cracks, tears, or stretched-out webbing. Test the ratchet or pin-lock adjuster to confirm it holds tension and doesn't slip. Check the sweatband for mildew, hardened material, or missing stitching. If any suspension component is compromised, replace the whole suspension unit rather than trying to patch it. Our guide on how to assemble your new hard hat also covers proper suspension seating if you're swapping in a new one.

What are the signs a hard hat needs to be replaced entirely?

Retire the hard hat immediately after any hard impact, even if there's no visible damage, since the shell's energy-absorbing properties can be compromised internally. Also replace it if you find cracks, brittle or chalky shell material, damaged suspension, missing straps, or if it's simply past the manufacturer's recommended shell life. When in doubt, it's cheaper to replace than to risk a failed hard hat safety inspection during an OSHA site visit.
