1. Any device that contains a laser has to be classified depending upon the amount of laser light that someone might be exposed to During design and manufacture of the product the manufacturer assigns the laser product to one of the various classes defined in the Laser Product Safety Standard BS EN 60825 1 2007 The classes range from the safest which is Class 1 through to the most hazardous which is Class 4 For example CD and DVD players contain lasers to read the disk and because they are normally inaccessible to people they are classified as a Class 1 laser products Laser Pointers output more accessible power than CD DVD players and are normally limited to being Class 2 devices While most laser lighting effects products are Class 3B and Class 4 laser products These two classes have the highest potential to cause harm because they emit the greatest light output This is of course desirable and necessary for laser lighting effects A laser product that emits more than 5mW of light and less than 500mW is normally classified as a Class 3B laser product meaning it carries a risk of harming eyesight if viewed directly Are Class 3B Laser Lighting Effects safe to view Yes if used responsibly and in accordance with the relevant the guidance issued by the Health and Safety Executive In the simplest terms generally keeping the beams and effects above the audience will not present a hazard to those viewing the show or effects When you2. The worst case effect to look at directly is a static single beam because all the light energy is concentrated into one point The hazard distances for several different powers of typical Class 3B laser are shown in the table below to give an idea of the distances involved Laser Output Power 100mw 250mw 450mw Hazard Distance 20m 25m 36m 56m 76m Table 1 Static Beam Hazard Distances Note The values have been calculated assuming the characteristics of a typical laser lightshow device which has a beam spread of 2mradians Actual devices may differ in practice so this table should only be used as a guide Details of how to calculate laser hazard distances are detailed in the British Safety Stand ard and many laser safety text books It is also one of the topics usually covered in laser safety courses It can been seen that static laser beams can remain hazardous for considerable distances which is why projecting such effects into peoples faces in not recommended Remember projecting these beams overhead is fine as long as they or any reflections are not hitting anybody When an effect such as a tunnel is projected the continual scanning reduces the time the eye is directly exposed to the laser energy These types of effect are less harmful to aim at the audience directly The table below shows the hazard distances of a stationary circular tunnel with a spread of 50 degrees and a scan rate of 20Hz to give an idea of how it i
