Laser Classification
Laser safety classes
Laser systems are classified according to NF EN 60825-1 based on the level of risk for the user. Industrial laser cleaning systems typically fall into Class 3B and Class 4.
Class 3B
Class 3B lasers can cause eye injury when directly exposed to the laser beam. Diffuse reflections are generally safe, but protective measures are required.
Characteristics:
- Eye hazard risk
- Protective eyewear required
- Controlled work area
- Operator training
Class 4
Class 4 lasers present the highest level of risk. They can cause eye and skin injuries and may also present a fire hazard. High-power laser cleaning systems typically fall into Class 4.
Characteristics:
- High eye and skin hazard
- Dangerous direct and diffuse reflections
- Protective measures required
- Controlled work zone
- Risk assessment required
Safety and Regulations
Key safety requirements for operators
Laser cleaning systems classified as Class 3B and Class 4 present increased safety risks. They can cause serious eye and skin injuries if used improperly.
Operation requires:
- Appropriate protective equipment
- Risk assessment
- Operator training
Standards and Regulations
Systems are designed in accordance with the following standards.
Applicable standards and directives:
- NF EN 60825-1 - Bezpieczeństwo urządzeń laserowych
- EU Directive 2006/25/WE - Protection of workers from optical radiation
- Code du Travail (France) - French Labour Code
- CE - Compliance with European Union requirements

Recommended safety measures
To ensure the highest level of protection for operators and bystanders, it is recommended that appropriate safety measures be taken.
Basic protective measures:
- Laser safety glasses
- Safety zone
- Laser warning signage
- Restricted access
Laser Safety Training
Comprehensive preparation for safe operation
The use of industrial laser systems of Class 3B and 4 requires appropriate safety training in accordance with European Union regulations on optical radiation.
The employer is required to:
- Perform risk assessment
- Implement protective measures
- Train exposed operators
These requirements are defined by:
- EU Directive 2006/25/WE - optical radiation
- NF EN 60825-1 - laser equipment safety
- National regulations applicable in each EU country
Training includes:
Training does not include:
