New EN397 Head Protection Standards: What They Mean for Employers and Workers
When most people think about workplace safety, they think about procedures, training, and compliance. Yet one of the most important pieces of safety equipment on any site is often taken for granted – the hard hat.
The upcoming changes to the EN397 standard represent one of the most significant developments in industrial head protection for many years. These changes are not simply about compliance or introducing new technical requirements. They are about learning from real-world incidents, understanding how head injuries occur, and improving protection for the people who wear safety helmets every day.
At Hard Hat Awareness Week, our focus has always been simple: protecting people. These new standards are another positive step towards achieving that goal.
Why Is EN397 Changing?
The existing EN397 standard has served industry well for many years, but workplace risks continue to evolve. Research into head injuries, concussion, falls from height, and impact mechanisms has provided a greater understanding of how serious injuries occur.
The revised EN397:2025 standard has been designed to reflect that knowledge, creating a more evidence-based approach to head protection.
One of the biggest changes is the introduction of two categories of industrial safety helmets:
Type 1 – Designed primarily for workers operating at ground level.
Type 2 – Designed to provide additional protection for workers who may be exposed to impacts from multiple directions or who are working at height.
For many organisations, this distinction will prompt an important review of existing risk assessments and helmet specifications.
A Greater Focus on Real Injury Risks
Perhaps one of the most encouraging aspects of the revised standard is its recognition of how head injuries actually occur.
The standard now acknowledges the importance of rotational forces during an impact. These twisting movements are often associated with concussion and traumatic brain injuries. While a fully approved test method is still being refined, the industry is already moving towards technologies that help reduce rotational energy reaching the brain.
Innovations such as rotational impact protection systems are becoming increasingly relevant and may soon become an expected feature of advanced workplace head protection.
Keeping Helmets Where They Belong
One of the most notable changes relates to chinstraps.
Historically, some standards focused on allowing chinstraps to break under certain loads to reduce potential strangulation risks. However, industry evidence has shown that a far more common problem is helmets becoming detached during an incident.
The updated standard places greater emphasis on ensuring helmets remain securely fitted when needed most.
For workers operating at height, Type 2 helmets will require chinstraps as standard. This reflects a simple principle: a helmet can only protect you if it stays on your head.
Improving Visibility and Comfort
The revised standard also addresses practical challenges faced by workers every day.
Manufacturers will now be able to certify high-visibility helmet designs under the standard, helping improve worker visibility in busy environments.
Ventilation requirements have also been modernised. As temperatures continue to rise globally, heat management has become an increasingly important workplace safety issue. The new approach allows manufacturers greater flexibility to develop helmets that help workers stay cooler while maintaining protection.
Comfort matters. If equipment is uncomfortable, workers are less likely to wear it correctly. Better design ultimately leads to better safety outcomes.
New Optional Protections
The revised standard introduces additional optional certifications that may be highly relevant depending on the working environment.
These include:
- Anti-static protection for environments where static discharge could present a risk.
- Enhanced electrical insulation classifications.
- Molten metal protection for foundry and heavy industrial applications.
- Improved side, front and rear impact protection in Type 2 helmets.
The important message for employers is that head protection should never be treated as a “one size fits all” purchase. Selecting the correct helmet should always be based on a thorough risk assessment and a clear understanding of workplace hazards.
What Should Businesses Do Now?
The good news is there is no immediate need to panic.
A transition period has been established, giving organisations time to understand the new requirements and prepare accordingly.
However, this period should not be viewed as a reason to delay. Instead, it provides an opportunity to review current head protection policies, assess whether existing equipment remains appropriate, and consider whether newer technologies could provide greater protection for employees.
Many organisations may find that Type 2 helmets become their preferred option due to the broader protection they offer and the increasing recognition of work-at-height activities across multiple industries.
Looking Beyond Compliance
The most important thing to remember is that safety standards represent minimum requirements.
The goal should never be simply to comply with a standard.
The goal should be to prevent life-changing injuries.
Every year, workers suffer serious head injuries that impact not only their careers but also their families, livelihoods and futures. The best organisations recognise that investing in better protection is not a cost—it is a responsibility.
As technology continues to evolve, from advanced impact protection systems to intelligent helmet monitoring solutions, we have an opportunity to make workplaces safer than ever before.
Because at the end of the day, protecting your head is protecting your life.
Hard Hat Awareness Week exists to raise awareness of these conversations and encourage businesses and individuals to continually improve their approach to head safety. Together, we can help ensure that every worker returns home safely at the end of every shift.
