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.

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.

Equinox Cirrus 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 Cirrus 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 installation, (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.

Equinox Cirrus Safety

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.
