Laser safety from JustLaser

The possible applications of a JustLaser laser machine are nearly limitless. Giving employees sound training guarantees they’ll work with the laser safely and efficiently. We offer our customers the option of having special laser safety training for their entire team. The safety-relevant theoretical knowledge of laser technology will be linked with practical examples. An experienced expert with more than twenty years of practical experience with lasers and a relevant degree will come to your premises and train your staff with direct reference to your laser system and its specific applications. Of course, they will have many years of experience, extensive expertise and an open ear for any questions about challenges in day-to-day work.

With a JustLaser laser machine, you can rely on a product that conforms with the highest safety standards. Nevertheless, suitable protective measures are to be implemented for day-to-day work. Our laser safety training courses offer an ideal basis for handling a laser machine safely.

You can rely on the four-class classification system – obligatory throughout the world – to help you be able to assess how dangerous a laser beam is. Class 1 includes harmless laser machines, while those with the highest potential danger fall into class 4. Laser machines fall into the following laser safety classes depending on their accessible emission limit (AEL):

• Class 1: This includes harmless laser machines. Either their output is very low, or they are encased by protective housing that shields the laser beam.
• Class 2: Visible laser beams (400 - 700 nm) with a power output of <1mW, like that emitted by a laser pointer, fall into class 2. Class 2 lasers are safe as long as they interact with eyes for <0.25 seconds (i.e. the instinctive eyelid closing reflex, or the averting reaction kick in).
• Class 3: In this class, incorrect usage carries the risk of eye damage. Training employees who work with these laser machines is imperative.
• Class 4: Laser machines with an output over 0.5 W fall into this class. If used incorrectly, there is a risk to skin and eyes – both through direct or reflected laser beams and through scattered radiation. There is also a risk of fire through contact with flammable materials. It is, therefore, imperative that comprehensive laser safety training takes place before the first work cycle!

Laser safety training courses consist of two parts (and an optional test at the end): a) the direct risks of laser beams and: b) the secondary risks.

The latter is often inadequately recognised and includes (potentially hazardous) resulting chemical reaction products, fine dust, risk of fire, risks from laser pointers (usually underestimated), mechanical and electrical risks and risks from plasma emissions.

The training course revolves around work and safety-related questions such as:

• What are the basic dangers? How can they be identified?
• What are the dangers specific to lasers, i.e. dangers which are not associated with other processing methods?
• Which materials must not be thermally corroded (i.e. engraved or cut) using a laser?
• What protective measures are necessary, and what should be considered when choosing protective equipment?
• What secondary dangers are there?
• What needs to be taken into special consideration with regards to work safety?

In addition to a comprehensible theoretical part, you can expect our laser safety courses to include references to your operating practice, the materials to be processed and the processes to be applied to them. We therefore request a brief coordination meeting and / or an inspection of the production environment in advance.

There’s also an option for a written test to be carried out to quantify and document the expertise transferred. We can then go through the solutions to the test together to better cement the newly-acquired knowledge in your employees’ heads through repetition.

Length of training courses (guideline times – depends on the number of questions):

• Laser safety, 1 hour
• Secondary dangers, 1.25 hours
• Test, 0.5 hours
• Test solutions, 0.25 hours

OVERALL LENGTH (including two breaks) 3.5 hours
