Class 3B Laser Lighting Effect User Safety Guide ProLight Concepts Limited
Installation and Operation Notes
1. The laser should only be installed and operated by those that are aware of how
to operate laser, and what the various controls perform. The keyswitch provided
on the laser should help to prevent use by unintended people.
2. The laser should be mounted in a suitable and secure position in the venue, so
that once in position it is unlikely to be affected by unintended movement.
3. Prior to installation and operation of the laser, the paths of the beams and
effects should be considered, particularly with respect to how they will touch the
audience. If direct audience scanning is desired then the laser energy in the
effects needs to be considered to decide if the effects are safe for direct
viewing.
Introduction
Laser lighting products are used to create some of the most vivid and striking visual effects, and
are often noted for how they seem to produce solid shapes that cut through the air, and pick up
highly defined swirling smoke patterns. The light that is used to create these stunning effects is
different from normal light and therefore several precautions need to taken when using lasers to
ensure that the lighting effects are safe and enjoyable to view. The optical power output from the
kind of lasers used for lighting displays can be harmful if not properly setup or is misused. But
when used following the recommended health and safety guidelines, laser lighting effects no more
harmful than looking at any conventional lighting effect.
This guide has been put together to provide you with some background information about laser
safety, and guidance on the recommended health and safety requirements for using lasers in
public places. Although this guide covers the main points to consider when using laser effects,
users are advised to familiarise themselves with other guidance, particularly that issued by the
Health and Safety Executive, HS(G)95 The Radiation Safety Of Lasers Used For Display
Purposes, which is freely downloadable from the HSE website. Attending one of the laser safety
training courses, listed at the end of this guide, is also highly recommended.
Important Warnings
Class 3B Lasers have the potential to harm eyesight if viewed directly in the face, and
in many instances this may be the case, even if viewed over longer distances of several
tens of metres. Therefore before using the laser product you should familiarise yourself
with its operation, and also the safety aspects that need to be considered.
Laser lighting effects are quite safe to watch if installed and used correctly, and being
aware of a few basic factors will help you to achieve this. This guide has been prepared to
help provide a basic backgrounder to the key safety aspects, and is based on current UK
health and safety guidance on the use of lasers for public displays.

Equinox Geometrix Laser Safety
What is a laser?
A laser is device that produces a special kind of light that is different from normal light sources.
Laser light sources differ from normal light sources in that they can produce very intense beams
of light that can remain parallel over long distances. It is this high concentration of light that can
sometimes make lasers harmful to look directly into.
What is a Class 3B Laser?
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 you start to aim the laser effects
down into the audience area is when it becomes harder to tell if the effects could cause harm.
With a Class 3B laser lighting effect, the problem can arise if the beams or effects actually hit
someone’s face.
If in doubt, keep the effects above the audience.

Equinox Geometrix Laser Safety
What harm can a Class 3B Laser cause?
Class 3B laser devices can be harmful to eyesight if viewed directly. i.e. that is, the beam or effect
strikes the face of a person. The actual injury that a Class 3B laser can cause depends upon a
number of factors, including how long the laser beam enters the eye for, the intensity of light, and
what part of the eye it actually gets focused onto. The most susceptible part of the eye to receive
damage from a laser is the internal back wall of the eyeball, known as the retina. It is this part of
the eye that receives the light signals that are sent to brain. All light entering the eye gets focused
onto the retina.
Normal light sources such as traditional light bulbs and regular lighting effects are normally not
harmful to view. Lasers differ in that they can get focused down to very small points on the retina
that can literally burn holes on the back of the eye, which can lead damage to eyesight. This
process can happen in less time than it takes for a person to blink. There are no pain receptors
on the retina, so the person will be unaware of any damage taking place. Damage caused to the
retina is permanent, and can vary from unnoticeable loss of vision, through to severe loss of sight,
particularly if the damage occurs in the part of the retina that senses the central vision.
Are there any laws or licences relating to using Class 3B lasers?
There are no specific “laser licences” that anybody needs in order to own or operate a laser for
lightshow use. However, there is specific guidance issued by the Health and Safety Executive in
the form of a document called HS(G)95 The Radiation Safety of Lasers Used for Display
Purposes. HS(G)95 outlines a number of detailed points to consider when using lasers for
lightshow purposes.
Furthermore, since April 2010 new health and safety legislation was introduced in the UK that sets
legal limits as to the amount of laser light a person may be exposed to in the workplace. Class 3B
lasers have the ability to exceed the safety limits. The full title of the laser safety regulations is the
Control of Artificial Optical Radiation at Work Regulations 2010, which also define the need for risk
assessment of the exposure levels.
Most places of public entertainment operate under a Public Entertainments Licence, which is
issued by the Local Authority. The entertainment licence requirements will normally need to have a
specific provision covering the use of lasers at the venue, where it is expected that the laser instal-
lation, (whether temporary or permanent), is to operated in compliance with the HS(G)95 laser
safety guidance as part of the venue’s Public Entertainment Licence conditions.
The use of lasers, as any other equipment used for shows, will also be covered by more general
health and safety legislation, such as the Health & Safety at Work Act 1974, and the Management
of Health and Safety at Work Regulations 1999, etc. These regulations, among other things, state
that you must ensure the safety of people present at the event where the laser is used, and also
that a suitable risk assessment regarding the use of laser must be carried out.

Class 3B Laser Product Features
Class 3B laser products are required to have several specific safety features as part of their
design. These features are laid out in the British Standard on Laser Product Safety BS/EN 60825-
1:2007 and are a requirement of the product meeting CE approvals.
The important ones are listed below:-
1) Laser Safety Warning Labels
2) Key switch
3) Emissions Indicator
4) Remote Interlock Connector
Summary of each features purpose
The Class 3B laser projector should contain three Laser Safety Warning Labels; the starburst
symbol, aperture label, and the warning/classification label. The starburst is intended to show that
the product is a laser product, using the starburst symbol in the warning triangle. The aperture
label is located to indicate where the laser projector emits its beams. The warning/classification
label states the class of the laser product, the maximum output power, and the wavelength(s)
(colours) of the laser, along with a warning ” Laser Radiation – Avoid Exposure To The Beam”
The Keyswitch is provided to help limit the use of the laser projector to those that have key
access. Without the key inserted and in the on position, the laser will not emit an output. The idea
behind laser products having key switches is that only those people that are aware of how to
operate the laser safely should be given access to the keys.
The emissions indicator is intended to show when the laser is ready to produce a light output.
The Remote Interlock Connector will only allow the laser to function when the two pins are shorted
together. For lightshow use it is recommended by HS(G)95 laser safety guidance laser effects can
be overridden by a remote Emergency Stop switch. The remote interlock connector provides a
convenient way for such a switch to be easily added to the laser system, to provide this control.
Audience Scanning
Audience Scanning is the term commonly used to describe when laser effects are being directly
aimed at the viewing audience. This creates a very dramatic looking effect, as people can touch
the light, and look down smoky tunnels. But because the laser light can touch or scan past
people’s faces, it also carries a risk that it could cause damage to people’s eyesight, if they are
overexposed to the laser light.

Maximum Permissible Exposure (MPE)
The amount of laser light that a person can be exposed to without it causing harm to eyesight is
known as the Maximum Permissible Exposure (MPE) or Exposure Limit Value (ELV). These
levels are defined the in the British Laser Safety Standard BS/EN 60826-1:2007, and more
recently in the Laser H&S regulations. When people are exposed to laser light which is above the
MPE, it poses a risk of causing eye damage. This could be of concern when the laser effects are
viewed directly in the face or there is a chance that they could be.
How do I know what the MPE is?
Knowing what the MPE and exposure level is for a given laser effect is quite a complex and
involved process to establish. For it is dependant on a whole number of conditions and variables
that need to be taken into account. The laser safety standard BS/EN 60825-1:2007 contains the
data required to calculate the safe levels, but it is not straightforward to interpret. Laser Safety
\Calculation Software has been developed to help ease the task of establishing laser effects
exposure.
Laser Safety Officer
The PD IEC/TR 60825-14:2004 Laser Safety Guidance recommends that all establishments that
use, or businesses that work with Class 3B laser products, should appoint a Laser Safety Officer
(LSO). The Laser Safety Officer should be aware of the safety issues when using lasers, and is
responsible for overseeing how the laser is used. In smaller businesses, the LSO will probably
also be the installer, operator, owner etc.
Diffraction vs Direct X-Y Scanning Lasers
Diffraction type lasers have become increasingly popular in recent years creating laser effects that
split the beam into hundreds, if not thousands of less powerful beamlets. This type of effect is
usually much safer to view directly than traditional scanned beam effects, for the simple reason
that as the beam is split into smaller beams, the power in each beam is reduced. With x-y
scanning systems, even though it may look as if the power is being reduced by the movement,
the moment any beam crosses a person’s face, the full power of the beam may briefly enter
someone’s eye. Caution should still be used with diffraction effects, in particular ensuring that the
brighter central beams are kept above head height.
Separation Distances
Health and Safety guidance states that for supervised installations laser light above the Maximum
Permissible Exposure (MPE) should not be accessible to members of the audience. It also
recommends the area where the MPE may not be exceeded, extends from 3m above, and 2.5m
laterally from any location in the venue where members of the public may gain access during the
display. The following diagrams illustrate this.
Equinox Geometrix Laser Safety

Diagrams showing Separation Distances
Note. The 3 metre height specified is not the height of the actual projector, but it refers
to the height of the laser effect. Therefore having the laser projector positioned at 3m
height and aimed directly down is not what the guidance is saying.
Equinox Geometrix Laser Safety

What types of effect are safe to scan directly at audiences?
Fast moving laser effects with evenly distributed scan patterns, such as circular tunnels are
generally safer than effects such as finger beams, or effects with pronounced bright spots in them.
Diffraction grating type effects are typically safer to point towards an audience, as long as the
bright central spots are kept above head height. The important thing is to not guess if an effect is
safe or not, and if in doubt keep it above head height. Being aware of the laser’s hazard distance
is useful to know.
Hazard Distances
All display lasers have a characteristic known as the hazard distance for direct viewing (NOHD).
This is distance at which the hazard of viewing the laser directly no longer presents a hazard. i.e.
at any point between the laser projector and the calculated hazard distance, it may be hazardous
to view the laser directly. But viewing the laser directly from beyond the hazard distance is
considered to be safe.
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 10mW 30mW 50mW 100mW 250mW 450mW
Hazard Distance 12m 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 is reduced.
Laser Output Power 10mW 30mW 50mW 100mW 250mW 450mW
Hazard Distance 5m 9m 11m 16m 26m 35m
