Show laser safety is not magic - it's pure know how!An insightful article by Dirk Gantefort.
The problem: You find hardly or no for you useful info about it in the net
Why is that so?
Nowadays, anyone can download the laser protection regulations of any country from the Internet. However, prospective customers who want to operate their show laser "safely" often do not find the answers they would like. Practical application varies so much from user to user that questions such as "what is the distance from the laser to the audience" simply cannot/does not make it into the technical literature.
Example: you have a laser with 2W output power and you want to know how far away from the audience you need to be in order to safely laser into the audience.
There can be no answer to this on the web!Why not?!
Just one example:Nobody knows how big they set the output angle of their laser!
To illustrate, put their laser on their living room table. Now you can laser an area of 10m x 10m on their wall, or also an area of 1m x 1m! Everyone should be clear that at 10m x 10m the laser power is distributed over much more area and is therefore far less dangerous to the eye than at 1m x 1m. So the "output angle" of the laser is very relevant to laser safety.
So without discussing the output together with you, no one can give you an indication of distance from the laser to the audience - and that's just one example.
Another very important point is, the movement of the output image, which also plays a role in the distance from the laser to the audience. The difference between a fast moving laser beam, to a very slow, or even "standing beam" ( which, by the way, is "never" allowed into the audience ) is logically important.
Alone these two examples illustrate why they do not find information on the distance of show lasers to the audience on the Internet. And we haven't yet talked about the fact that all lasers have different beam sizes and divergences, which play a bigger role than you might think.
To be on the safe side, therefore, seek expert advice on the subject of "laser safety." Last but not least, we work with Dr. G. Uhlig, who is regarded in professional circles as "the" expert for laser systems and their acceptance "on site" according to BGV B2. He has worked for TÃV Sued Industrieservice for more than 30 years until the end of 2020.
Discuss the framework:
Discuss with us spatial conditions such as the ambient brightness, the nature of reflective surfaces, or the minimum height at which your laser will be used. Together with the issues already addressed, we can then provide you with the best possible advice.
As long as you take these things into account, safe laser output is straightforward and not magic, or incomprehensible theory.
Call us anytime to ask your questions, and remember: On this topic, there are "definitely" no stupid questions - and "no stupid answers from us!
Lasering is fun - if you have a safe feeling about it - even more!
The definition of laser safety officer ( LSB ):
When using a class 3R, 3B or 4 laser (according to accident prevention regulation "Laser Radiation" BGV B2), a Laser Safety Officer must be appointed in writing by the entrepreneur. The entrepreneur can take over this task himself. The basis for the appointment is Â§ 6 of the BGV B2 regulation. Laser safety officers must have sufficient expertise. This can be demonstrated either by professional training or by experience. Furthermore, the implementation instruction recommends participation in a training course that complies with the regulations of the professional associations.
The laser protection officer must clearly mark the laser protection areas and must regularly test the emergency stop for their function. In most cases, the laser safety officer is also responsible for reporting the laser to the relevant occupational health and safety authority and coordinating the acceptance by a state expert. Furthermore, he has to advise the entrepreneur in many areas, for example, in the selection of protective equipment, instruction of employees and investigation of accidents with laser radiation together with the specialist for occupational safety.>.
