A laser safety booth is an enclosed workspace designed to contain laser radiation during laser processing, creating a controlled environment that helps protect operators and nearby personnel from accidental exposure while handheld laser welding is carried out. For many industrial applications it forms an important part of an overall laser safety strategy alongside operator training, PPE and suitable risk assessments. Weldability SIF supplies the Cepro Unisonic Class 1 laser safety booth, and our Certified Laser Safety Officer can advise whether an enclosure is appropriate for your application.
What is a laser safety booth?
A laser safety booth is a dedicated, enclosed area that contains the laser process within defined boundaries. By separating laser welding from the rest of the workshop, it improves safety, reduces distractions, helps control access and creates a professional, organised environment for laser welding.
Because handheld fibre laser welders are Class 4 laser products, the working environment matters as much as the machine itself. A booth provides an engineering control: it contains the laser process in one place, which reduces the risk of accidental exposure and makes access far easier to manage than relying on temporary measures alone.
What does Class 1 mean in a laser enclosure?
A Class 1 laser enclosure is designed so that, during normal operation, laser radiation is contained within the enclosure, reducing the risk of exposure outside the booth. This is an important distinction: the laser process happening inside may use a Class 4 handheld welder, but the engineered enclosure brings the working environment around it to Class 1 during normal use.
Class 1 enclosures are widely used in industrial environments to help create a safer and more controlled laser welding workspace. They are a practical way to manage a powerful process without disrupting surrounding production.
Why does an enclosure simplify access control and compliance?
A purpose-designed enclosure offers defined boundaries, controlled access and a consistent working environment that temporary laser screens cannot match. Screens may form part of a strategy, but they do not provide the same level of controlled enclosure as a dedicated booth.
A booth supports your wider laser safety strategy in several ways:
- Protecting other employees. Containing laser operations within a dedicated enclosure helps separate welding from surrounding work areas, so other employees can continue working nearby without being exposed to the laser process, provided the booth is used correctly.
- Managing visitors. An enclosed booth clearly defines where laser operations take place, reducing the likelihood of visitors entering an active laser work area unintentionally. Visitors should always follow the site’s health and safety procedures.
- Supporting compliance. A laser safety booth supports a business’s overall laser safety strategy by providing an enclosed, controlled working environment. It should be considered alongside risk assessments, operator training, maintenance procedures and other appropriate control measures — see our guide to laser welding safety requirements.
Important features to look for in a booth include appropriate laser protection, robust construction, good operator visibility, reliable door interlocks, practical access, integration with extraction systems, ease of installation and future expansion options. Safety interlocks in particular help prevent the laser from operating if access doors are opened unexpectedly, forming a key part of the overall safety system.
What is the Cepro Unisonic laser safety booth?
The Cepro Unisonic is a Class 1 laser safety booth developed specifically for industrial laser applications. Weldability SIF selected it because its modular construction, engineered safety features and practical design make it well suited to businesses implementing handheld fibre laser welding, rather than offering a generic enclosure.
Its modular design brings real flexibility:
- Adaptable to your layout. Most laser safety booths, including the Cepro Unisonic, are designed to be installed within existing workshops without major structural changes. Weldability SIF can assess your available space and recommend a suitable layout that integrates with your production environment.
- Relocatable. Many modular booths can be dismantled and relocated if production requirements change or the business moves premises, making them a practical long-term investment for growing businesses.
- Extraction-ready. Laser welding produces airborne contaminants that should be controlled. The Cepro Unisonic can be specified as part of a complete solution that includes appropriate fume extraction, and we work closely with Extractability to integrate suitable extraction solutions.
Combined with professional installation and technical support, the Cepro Unisonic provides a robust platform for safe handheld laser welding.
Open workshop or enclosed booth — which is appropriate?
This depends on your workplace, the welding application and the findings of your laser risk assessment. The need for a booth is never assumed; it follows from the risk assessment.
Where handheld laser welding is carried out in an open workshop, suitable control measures are essential to protect operators and anyone nearby. In many situations an enclosed laser safety booth offers the most practical solution, because it provides a permanent, organised area where operators can work without repeatedly setting up temporary safety barriers. A dedicated booth can therefore improve workflow and productivity while maintaining a strong focus on safety.
A single booth can also serve multiple trained operators working at different times, provided suitable operating procedures are followed and the booth is used within its intended design. The space you need depends on the size of the laser system, the workpieces being welded and operator access requirements — a site survey helps determine the most suitable booth size.
How does a booth fit with PPE, controlled areas and the LSO?
A laser safety booth is one engineering control within a broader system, not a replacement for the rest of it. The safest installation considers both the equipment and the working environment together. A booth works alongside:
- PPE and safe operating procedures, which remain essential even with an enclosure in place.
- Risk assessment, which determines whether a booth is needed and how the controlled area should be defined.
- Operator training, so the booth and machine are used correctly and safely.
- The Laser Safety Officer. A Certified Laser Safety Officer helps bring these elements together — advising on machine safety, suitable enclosures, controlled areas and training to simplify implementation and reduce risk.
Good planning before installation helps the booth fit comfortably within the workshop, allows efficient material handling and integrates with power supplies, extraction systems and production flow.
Where do HPC Laser Systems and static enclosed systems fit?
HPC Laser Systems is a manufacturer of industrial fibre laser equipment designed for professional manufacturing and fabrication applications, including the handheld fibre laser welding machines Weldability SIF supplies. The booth provides the controlled environment in which these systems operate safely.
A successful laser welding installation includes more than just the machine: machine selection, laser safety, operator training, risk assessments, fume extraction, enclosure design and ongoing technical support all contribute to long-term success. Weldability SIF brings these elements together. As a supplier of handheld laser welders, Cepro Unisonic Class 1 laser safety booths and integrated Extractability fume extraction, supported by our Certified Laser Safety Officer, we help businesses implement laser welding with confidence.
