Introduction

A laser pointer, or laser pen, is a small visible laser device designed to highlight something of interest by projecting a small bright spot of coloured light onto it. They are usually portable, low powered, battery operated hand held laser devices. For more information about laser pointers visit the HPA’s website on Laser Pointers.

Safe laser pointers

The University only allows laser pointers to be used for presentation purposes and it is strongly recommended that an alternative presentation tool is used.

Laser pointers used in the University must meet the following conditions.

• The laser pointer classification is lower than Class 2.

• The laser pointer is purchased from a reputable manufacturer or supplier.

•  The laser pointer is not ‘home made’.

• The laser pointer has not been modified in any way, for example optics added to focus the beam.

• The laser pointer is only used for presentation purposes.

Higher class laser pointers are strictly prohibited by the University because the power output can cause significant eye damage and flash blindness. If the laser class is unknown or it is suspected that it may be greater than a Class 2, do not take unnecessary risks and do not use it. A Laser Pointer Toolbox Talk has more information on the harm from powerful laser pointers. Laser pointers used in a malicious way or used for recreational purposes can present a significant risk to health and safety and is prohibited.

Advice is available from the University Non-Ionising Radiation Protection Advisor (UNIRPA) if you are unsure.

Good practice in the use of laser pointers

Below is good practice in laser pointer use.

• Consider an alternative presentation tool or aid.

• Use laser pointers Class 2 or below.

• Follow the manufacturing safety instructions.

• Restrict use to the owner only.

•  Store the pointer securely, ideally with the batteries taken out.

• Carry out a visual check of the room before the presentation to ensure there are no reflective surfaces which might divert the beam back into the audience or towards the presenter  e.g. mirrors, chrome fixtures and fittings, white boards.

• Switch the pointer off and put it down when it is not in use.

Examples of unsafe practice.

•  Allow others to borrow the laser pointer, especially children.

• Direct the beam towards the audience.

• Look into the laser aperture when it is off or on.
