Generally, most safety helmets are recommended to be replaced every 3 to 5 years, depending on usage frequency, environment, and maintenance.
High temperatures, UV exposure, and humid conditions accelerate aging of the plastic shell and foam.
Helmets used frequently outdoors, exposed to sunlight and mechanical stresses often have shorter lifespans.
Below is a reference table for recommended replacement intervals for different helmet types:
| Helmet Type | Suggested Replacement Interval |
|---|---|
| High-altitude / industrial safety helmet | ~3 years |
| Climbing / outdoor helmet | 3 – 5 years |
| Bicycle / skateboard helmet | 3 – 5 years |
| Ski / winter sports helmet | ~3 years |
After a Significant Impact or Drop
Even if the outer shell seems undamaged, the internal EPS foam may be compromised and no longer able to absorb energy as designed.
Visible Cracks, Fractures, or Deformation
Whether in the shell, liner, supports, buckles, or connectors—any visible structural damage necessitates replacement
Aged or Deteriorated Liner / Foam
Yellowing, hardening, disintegration, or adhesive failure in foam or liner layers reduce cushioning capability.
Long-term Exposure to Sunlight, Chemicals, Extreme Heat
UV, solvents, heat cycling can embrittle plastic and degrade elasticity or structural strength.
Accessory or Component Damage
Broken buckles, worn adjustment mechanisms, frayed straps, or damaged visor/mounting parts can compromise fit and stability, reducing protection.
Even if none of the above have occurred, if a helmet approaches its recommended service life (e.g., 3–5 years), consider replacing it proactively.
Visual inspection: Look for hairline cracks, surface crazing, chalking, discoloration, or the “network of fine cracks” typical of aging.
Structural check: Test adjustment systems, internal supports, liners for looseness or deformation.
Compression / elasticity test: Gently squeeze helmet sides inward ~1 cm; compare rebound behavior with a fresh helmet. If rebound is noticeably slower or any cracking occurs, replace.
Component test: Fasten and unfasten buckles, test strap tension, move adjustment dials—see if anything slips or feels weak.
Label / date check: Locate internal labels or production dates. If the helmet has exceeded the manufacturer’s recommended lifespan, it’s time to replace.
Avoid prolonged sun exposure—do not leave helmets in direct sunlight, such as on a car dashboard.
Avoid contact with harsh chemicals (strong acids, alkalis, solvents).
Store in a cool, dry, shaded, well-ventilated place.
Clean liners periodically using mild soap and lukewarm water; air dry fully before reassembly.
Before each use, briefly inspect the helmet to ensure all parts remain functional.
When it’s time to replace, opt for helmets that are certified to international safety standards and built with quality in mind. Our company offers a range of industrial safety helmets / climbing helmets / skateboard helmets / bicycle helmets / ski helmets, all made with advanced composite materials (EPS + PC/ABS), and tested under CE / EN / ASTM standards for impact resilience, lightweight design, and easy disassembly/cleaning.
Based on your usage scenario (commuting, extreme sports, industrial work, etc.), we can help you select a model that fits best.
A seemingly intact helmet may no longer offer reliable protection. Timely inspection and replacement are essential practices for safety. Stay vigilant and always prioritize protection—because your head deserves nothing less.
