From the end of 2013, all the Laser Embedded Laser Harp we craft, are classified as Class IV Laser devices.
This means that they follow safety standard, which we applied also in the old Class 3b products in the past. Even if it was not required for 3b classes.
On top of all, they must be used only from specialized person and/or the musician that has to play with, must be very careful and read out, understand, all the Safety recommendations are written also on the Manual given with the devices.
Her/his behavior is expected to be very strict to what the Manual declares and even more severe than it, but certainly not lighter than that.
Taking into consideration that our Laser Harps are Musical Instruments and not devices that should be used for other purposes than this or in dangerous environment (e.g. with explosive gases etc), the safety systems installed, should be able to protect the personnel, and at the same time permit the use tf the Laser Harp in the goal they are designed for.
LASER HARPS by KROMALASER are PROFESSIONAL MUSICAL INSTRUMENTS
The laser Harps we craft, are intended to be used as Musical Instrument and the Musician/DJ plays them, should have read the Manual with all the instructions and warnings
From the moment you receive the Laser Harp, you are the person that's aware about all what concerns the instrument and the way in which you handle it, because clearly reported into the documentation we release together with the Instrument
All the parts of the laser Harps which are hazardous, are clearly signaled by conventional/standard labeling placed just aside that zones.
Please take care to these signalization/labeling and respect them carefully.
Those labels and the danger notes are also reported into the manual.
FORBIDDEN TO OPEN THE DEVICE
In all the nations of Europe (EU), there is the application of what is called "Common Sense".
To enforce this, we seriously declare here that's strongly forbidden for any user, to open the device for any reason.
The opening of the device, is admitted only by Laser technical Specialist personnel.
We strongly encourage you to send your Laser Harp, in case you need any reparation's intervention, directly to our Laboratories.
We are not responsible about any damage against persons/animals/things, if you violate any of the requirements expressed above, hereby, and into the manual.
Laser beams must never be pointed toward any reflective surfaces, that can point them toward the eyes/body of any living being.
In case of white Ceiling, we always suggest to put a black tape or not reflective surface, in the ceiling's zone where the lasers are pointed.
We are selling the tape in our Accessories section.
On stage, take care that laser are going directly into sky or they are not reflected by any surface like the scaffold or else.
If you use the SkyCeil to create the spectacular Laser Ceiling, you are responsible to prevent that the deflected Laser Beams, are hitting any living being/reflective object.
MIRRORING for UPRIGHT LASERS
The use any not-Kromalaser Laser Projector with ILDA Controller to have the Laser Harp, implies the installation of external 45 degrees mirrors to deflect the laser beams, so that they become vertical
This manner to use the projector, suggested or indicated by other companies, is very dangerous. Indeed a simple misalignment of the mirror, due small accidental movements on the Stage or else, can hazard the eyes of the public.
To avoid this, we have designed and built special projectors, that have the mirror system internally installed and carefully set up. So that our projectors are really safe
With our projectors, you have the warranty that lasers beams are always emitted upright, and you don't need any external mirror, hence you have not to worry about vibrations or movements when you are on Stage
Each Laser Harp, with laser projector embedded, have a Keylock system, that interdicts the device in case the key is not inserted and turned.
Who has the key, is the formal responsible of the use of the harp.
When the key is out, or is placed in but not turned, there's no way to activate the Laser Harp
The remote interlock connector Class 4 lasers should be connected to an emergency master disconnect interlock or to room, door or fixture interlocks.
We provide this connector as it's required on any Laser 4 device ( IEC 60825 )
KEYLOCK ENFORCEMENT and INTERLOCK ENFORCEMENT
FOOTSWITCH LOCKING SYSTEM (the enforcement)
Safety norms are just describing the requirement to have a keylock. We did more.
Since the beginning, we have enforced this requirement, applying the necessity to press contemporaneously the pedals 1 and 4, to activate the lasers.
This, together with the keylock, avoids accidental turns on, by personnel which is not supposed to have access to the Laser Harp, nor to it's use and handling.
Light weight instruments, can by tilted down/flipped by rough use (by a strong kick for instance).
While the heaviest ones, due an not attentive use during the setup of the stage.
It means that there is the risk that the laser beams are reaching the eyes of any the people and this must be avoided.
Norms are prescribing the interlock system, which deactivates the lasers by disconnecting a plug or pushing an emergency button.
What the TILT SENSOR does as INTERLOCK ENFORCEMENT:
The interlock foreseen by norms has a dangerous drawback: it takes too long to be activated, and lasers are damaging eyes in milliseconds.
To be more effective than what norms are suggesting, our Interlock system is a tilt sensor.
Indeed our laser harps must be used with lasers coming out upright, in vertical!
Or at an angle determined by the laser Fan itself, which we established during manufacturing process, which has not any risk for accidental laser hit (anyhow you should always take care for!)
For the reasons above, if ever the Laser Harp is bumped, with risk of tilt, and/or tilted the laser system and the whole circuitry goes immediately off, avoiding any accidental possible contact with the eyes of any body surrounding it.
At the same time an acoustic alarm turns on and the only one way to reset the Laser Harp restarting the lasers, is to put the laser harp in its working position, as foreseen by its Manual, to unplug and re-plug the power by the mechanical switch.
This solution is much more effective and quick than any pushbutton in the world, and it's meant to protect you much more.
We placed the Tilt Sensor also in the projectors we are crafting and selling, for Laser Harp as Musical Instrument Purposes
In certain cases, especially when the Laser Harp is more portable, thus subjected to be easily handled by not so expert personnel, there is a cover with 2 locks.
Closing it when the instrument is not used, as recommended, with the keys we give when we ship the laser harp, prevent access to the harp itself.
Who owns the keys of the laser harp is formally responsible of any damaged caused by any imprudence
Goggles are special protective glasses. they are NOT Sunglasses, thus please do not make any confusion amount the two types of glasses!
The following items are the feedback of the major certified goggles manufacturers
Goggles are made with special lenses that are attenuating only a specific wavelength.
Moreover they are not meant to protect you against long direct contact between your (or third parties) eyes and the lasers.
They are meant only to protect against brilliant reflections of the lasers (accidental hits) which can accidentally reach your or third parties eyes.
moreover, goggles are generally made to protect against one specific wavelength, thus only one color.
There are goggles protecting against two colors, which are very expensive and very difficult to find and to order. But if you ask for, we can order them
Multicolor goggles, made for three or more wavelengths at the same time, are not existing in the world, because they are very difficult (almost impossible) to be built. So far goggles are not employable for this application, because whenever thy are built, the y are so dark that are not usable for these application. Indeed, because the human visible spectrum lies between 380-780 nm, to protect from all the radiations, you need a totally non-transparent material. black. Thus on rainbow effects etc, you are using the whole visible radiations and you need to see the lasers in order to use them. Thus it's physically impossible to build such kind of goggles: which protects you, but permits you to watch the lasers
With CLASS IV to protect your eyes is MANDATORY But the current norms are not specifying the degree of protection and/or the wavelength on which the glasses should protect your eyes
To protect your eyes, be attentive, careful and applying your common sense.
Playing in certain rooms the reflections from the ceiling may give some issue.
Indeed, especially with green lasers, the reflected light is so strong that you can easily read and write documents with.
To prevent any strange behavior of the laser harp with strong reflecting surfaces as low and white ceilings (these last ones: frequently used in US and North Europe), we suggest to apply this special tape to the ceiling and all the issues will be solved.
