The ‘light’ produced by a laser, a form ne non-ionising radiation, has a unique combination of characteristics that distinguishes laser radiation from all other light sources. Lasers come in various forms and have many uses at work, in the home and for leisure: Lasers emit radiation as narrow concentrated beams of light, not necessarily visible to the human eye. Their most commonly-recognised hazard is their ability to damage eyesight or burn skin, which can vary markedly according to the wavelength and power of the output.

However, in some cases, other associated risks from use of the equipment may be more hazardous such as heat, dust and fumes.

Class 1C – Safe without viewing aids, lasers are designed explicitly for contact applications to the skin or non-ocular tissue. Class 1M – As Class 1 but not safe when viewed with optical aids such as eye loupes or binoculars.

Class 2 – visible beams only the eye is protected by the aversion responses, including the blink reflex and head movement. Class 2M – As Class 2 but not safe when viewed with optical aids such as eye loupes or binoculars. Class 3R – More likely to cause harm to 60285-1 eye than lower class lasers but do not need as many control measures as higher class lasers. Class 3B – Eye damage likely to occur if the beam is viewed directly or from shiny reflections.

Code of Practice – Laser Safety

Class 4 – Eye and skin damage likely form the main laser beam and reflected beams. These lasers may cause fires. Many items of scientific equipment are Class 1 lasers and may also be regarded as ‘safe’, for example spectrophotometers and particle eh. These products may contain a higher powered laser as an embedded component but it is not accessible in normal use. The HSE guidance also identifies that some lasers are perfectly safe under normal conditions of use but have the potential to cause bd if used inappropriately, for example if held very close to the eyes.


They give examples of Class 1M, 2 or 2M lasers, for example some low power laser pointers in wn tools. Some scientific and technical equipment may also contain Class 1M, 2 and 2M lasers. Class 1C lasers are engineered to be ocular safe. The HSE guidance gives examples of ‘hazardous’ lasers that present a ‘reasonably foreseeable’ risk of harming the eyes and skin of workers and where control measures are needed. All use of Class 3B and 4 lasers in industry, research and education is specified 660825-1 ‘hazardous’ because of the potential to cause damage to eyes including blindness, burns to the skin, and fire.

The guidance also states that lasers which would not otherwise be accessible, for example in a Class 1 product, but which are exposed during manufacture or repair of the equipment may also be ‘hazardous’ lasers for the duration of that activity. The HSE guidance ej out the control measures to be considered on a case-by-case basis to reduce the risk of harm to the 608255-1 and skin of workers to as low as is reasonably practicable. For use of Class 3B and 4 lasers in industry, research and education the key measures to be considered are:.

They are therefore included in the main provisions of this Code. Misuse of laser pointer can cause damage to eyes. Under this Code of Practice, only Class 1 or 2 lasers may be used for demonstration, display or entertainment. Members of staff wishing to use a Class 3 laser pointer must first consult the Sn Laser Safety Adviser.

When operating laser pointers, users must ensure that they follow the manufacturer’s safety 60285-1, use them in a safe manner and do not expose themselves or others to the beam. Laser pointers are not to be modified in any way.

They are responsible for. Equipment classification and requirements. A user’s guide originally included in Part 1 of the British Standard. Other British Standards in this series cover laser processing machines, optical fibre communication systems OFCSand laser displays and shows. Class 1 – Safe under reasonably foreseeable conditions of operation.

For use of Class 3B and 4 lasers in industry, research and education the key measures eb be considered are: Laser pointers Misuse of laser pointer can cause damage to eyes. Responsibilities under this Code of Practice Faculty Operating Officers and Directors of Professional Services are responsible for Ensuring there is an up-to-date list of all scientific and technical lasers and laser users. Ensuring that lasers of Class 3R and above, and their users, are registered on the University laser registration form and the University laser user registration form and that a copy is sent to the University Laser Safety Adviser.


Registrations must be made prior to first use and then updated for be. Ensuring a laser survey form is completed for each laser of Class 3R and above prior to first use and on an annual basis thereafter.

Ensuring a risk assessment is completed in an approved format and written procedures for use are produced prior to use for the first time of any laser of Class 3R and above. The written procedures for use 60825–1 be kept in the same area as the laser.

The risk assessment and procedures must be reviewed and if necessary revised at least annually or if there are significant changes. Ensuring risk 608825-1 and laser survey forms een Class 3B and 4 lasers are forwarded to the University Laser Safety Adviser with the laser registration form prior to first use. Addressing any problems notified by the Laser Safety Supervisor that arise from the annual ns.

It is the responsibility of the appropriate academic supervisor to address any such problems. Addressing any recommendations made by the Head of Health and Safety for remedial action following ej annual audit.

Assisting in preparing and keeping up to date University Policies and Codes of Practice relating to laser safety. Advising officers in charge of design and construction of new buildings and the modification of existing buildings on matters affecting laser safety.

Liaising with the Head of Health and Safety and University Occupational Health Service on matters relating to medical examinations and health of registered laser workers. Reporting all lasers of Class 3R and above, and users of lasers of Class 3R and above, to the University Laser Safety Adviser, using appropriate registration forms.

Assisting in risk assessment and drawing up of written procedures for use of all lasers in their Departments. Ensuring that information and precautions identified by the risk assessment, are available to laser users.
