How Often Should You Replace Safety Helmets in Australia

Last Updated:24 July 2025

There is no legislation on how often job site hard hats must be replaced. However, guidelines are recommended, like bicycle helmets and general safety equipment. Helmets will deteriorate over time with regular daily use. A compromised hard hat will not provide complete 100% protection for the wearer and is a severe safety concern. 

Frequency for Replacement 

So, how often should you replace your personalised hard hats? There are many different factors, including the industry that you operate in. Here are the general guidelines we recommend to our clients: 

Standard Every 5 Years: Even if your hard hat doesn’t show visible signs of damage, we suggest replacing it every five years. Over time, the materials can degrade due to regular exposure to the elements. Job sites in Australia can be highly challenging, especially in outdoor environments. Wear and tear, and environmental factors like sunlight and chemicals. Regular replacement ensures that your hard hats meet safety standards and provide the protection your employees need. 

 High-Risk Environments—Every 2 Years: Hard hats should be replaced every two years in high-risk environments where exposure to extreme temperatures, sunlight, or chemicals is daily. Only job site managers will be adequately equipped to know the extent of the harsh conditions. These conditions can accelerate the degradation of the helmet, which is why it’s essential to replace them more frequently in such environments. 

 Immediate Replacement for Damaged Hard Hats: If a worker feels any impact when wearing, then caution is immediately required. Check your hard hat for visible damage, such as cracks, dents, or other structural issues. Read our article on how to inspect hard hats for damage. Replace immediately if helmets have any sign of damage. Dispose of the helmet in case other people reuse it. Even minor damage can compromise the helmet’s ability to protect the wearer. It is always better to be safe than sorry. 

Tip for Purchasing:  

Tracking Replacement Dates: Record when each hard hat was purchased and note when it should be replaced. This helps ensure your team always wears hard hats that are up to standard. Many companies implement a maintenance schedule for hard hats, making tracking their condition easier and ensuring they are replaced when necessary. 

With regular maintenance and replacement, you can ensure your team is always well-protected. If you need to order replacement hard hats or bulk orders for your team, contact us to discuss your requirements. Ready to purchase personalised safety hard helmets?
