Service Life of Safety Helmets

Safety helmet expiry dates: What do they mean?

Safety helmet expiry dates are more than just numbers stamped inside your PPE, they’re a critical indicator of whether your head protection is still safe to use. A helmet that looks intact may no longer provide the protection you rely on. Over time, materials degrade even if the helmet has never been used.

In this guide, BBU® Safety explains what safety helmet expiry dates mean and how long safety helmets last.

What is a safety helmet’s lifespan?

Safety helmets are a vital part of staying protected on site as they are designed to shield people from impact, falling objects, and electrical hazards. However, like all PPE, they don’t last forever. Most safety helmets have a recommended lifespan of three to five years from the date of manufacture. This can vary depending on the brand, usage conditions, and environmental exposure.

Helmet longevity can be affected by several environmental and usage-related factors. Prolonged exposure to UV light can weaken the shell material, while sweat and moisture may degrade the internal padding. Frequent use contributes to wear and tear on the suspension system, and improper storage such as leaving helmets in direct sunlight or damp areas can accelerate deterioration. Even if a helmet appears intact externally, its protective performance may be compromised. Regular inspection and awareness of these factors are key to ensuring your helmet continues to offer reliable protection.

TOP TIP, People often forget about proper storage. Be sure to not leave your helmet out in the sun or on a parcel shelf of a vehicle in the sun. Place your helmet somewhere cool and dry out of sunlight.

How do I know if my helmet is still safe?

Helmets can degrade without showing obvious signs. Therefore, before each use, it is important to check for:

If any of these signs are present, replace the helmet immediately. Continuing to use a compromised helmet can significantly increase the risk of injury in the event of an accident. A helmet that no longer meets safety standards may fail to absorb impact effectively, putting the wearer at serious risk.

TOP TIP, A more thorough inspection should be done monthly to ensure that there is no hidden damage, that could reduce the protection a helmet should provide.

Do safety helmets expire?

Yes, safety helmets do expire. Manufacturers typically include a manufacture date and a recommended replacement timeframe. These markings help users determine when a helmet should be retired from service. Even helmets that remain unused over time are still subject to degradation. This is due to the natural ageing of materials, which can lead to reduced flexibility, brittleness, and diminished impact resistance. Exposure to ambient conditions such as temperature fluctuations and humidity can also accelerate this process, making it essential to monitor helmet age regardless of usage.

For example, BBU® Safety helmets are recommended as 3 years in use and 2 years in storage from the date of manufacture, or sooner if signs of damage, wear, or impact are present. If a helmet experiences any form of impact, even if no visible damage is apparent, it should be replaced immediately to ensure continued protection.

In conclusion, any safety helmet that has exceeded five (5) years from its date of manufacture shall be replaced immediately

How to check the expiry date of a safety helmet

Knowing how to check the expiry date of a safety helmet is essential. To know if a helmet is safe to use follow these steps:

Locate the manufacture date – Most helmets feature a raised circular marking moulded into the shell. The year is displayed inside the circle, and an arrow points to the month of manufacture. Other helmets may feature the manufacturer date in a MM/YYYY or M/YY format

Always choose helmets marked with a production date stamp. You can never know exactly when the production date was written on helmets that are laser-marked later. Absolutely do not accept laser-marked or ing printed helmets.

Verify certification markings – Check for standards such as EN 397 to confirm compliance.

If markings are missing or illegible, replace the helmet immediately. A helmet without clear traceability may not meet current safety standards, putting the wearer at risk.

Conclusion

Understanding safety helmet expiry dates is essential for maintaining workplace safety and compliance. Here’s a quick recap:
