Understanding Safety Helmet Standards

Industrial safety helmets may look similar, but different standards define different protection requirements, testing methods, and classifications.

For companies purchasing PPE, understanding the difference between EN 397 and ANSI Z89.1 helps ensure workers receive the right protection for their working environment.

This guide explains the key differences between these two major industrial helmet standards and how to choose the right safety helmet based on workplace risks.

What Is EN 397?

EN 397 is a European standard for industrial protective helmets. It defines requirements for helmet design, performance, testing, and marking.

EN 397 focuses mainly on protection against workplace impact hazards, especially falling objects.

EN 397 Type 1 vs Type 2

Type 2 helmets are designed for workplaces where workers may face more complex impact risks.

What Is ANSI Z89.1?

ANSI/ISEA Z89.1 is an industrial head protection standard commonly used in the United States.

ANSI helmets are classified by:

Impact Type

Type I

• Designed mainly for top impact protection

Type II

• Provides additional lateral impact protection from the front, rear, and sides

Electrical Classification

Electrical classification is important for workers in power, utility, and electrical maintenance industries.

EN 397 vs ANSI Z89.1: Key Differences

Although both standards provide industrial head protection, they are not interchangeable. A helmet certified to one standard does not automatically meet the requirements of the other.

How to Choose the Right Safety Helmet?

The right helmet should always be selected according to workplace hazards.

1. Identify the Working Environment

Different industries require different protection:

• Construction

• Electrical work

• Mining

• Oil & gas

• Manufacturing

2. Evaluate Impact Risks

Consider whether workers may face:

• Falling objects

• Side impacts

• Moving equipment hazards

For higher impact risks, helmets with enhanced lateral protection may provide additional safety.

3. Check Electrical Requirements

For electrical environments, confirm the required electrical protection level before selecting a helmet.

Class E electrical helmets are commonly used in applications involving electrical hazards.

4. Consider Comfort and Fit

Workers often wear helmets for many hours. Important features include:

• Ventilation

• Suspension system

• Adjustable fit

• Lightweight design

A comfortable helmet improves long-term wearing compliance.

FAQ

Is EN 397 the same as ANSI Z89.1?

No. They are different industrial helmet standards with different testing and classification systems.

What is the difference between Type I and Type II helmets?

Type I focuses mainly on top impact protection, while Type II provides additional lateral impact protection.

How do I choose the right safety helmet?

Choose based on workplace hazards, impact risks, electrical requirements, and required certification standards.

Conclusion

Choosing the right industrial safety helmet is not only about certification. The best helmet should match the actual workplace environment and protection requirements.

By understanding EN 397 vs ANSI Z89.1, companies can make better PPE decisions and improve worker safety.
