The ‘light’ produced by a laser, a form of non-ionising radiation, has a unique combination of characteristics that distinguishes rn 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 bss 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.
Code of Practice – Laser Safety
However, in some cases, other associated risks from use dn the equipment may be more hazardous such as heat, dust and fumes. Class 1C – Safe without viewing aids, lasers 608251 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 the 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.
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 sizers. 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 harm 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 surveying tools. Some scientific and technical equipment may also contain Class 1M, 2 and 2M lasers. Class 1C lasers are engineered to be eh 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 as eb because of the potential to cause damage to eyes including blindness, be to the skin, and fire.
The guidance also states that lasers which would not otherwise be ne, 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 sets out the control measures to be considered on a case-by-case 6025-1 to reduce the risk of harm to the bbs 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:. 608251 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 University Laser Safety Adviser. When operating laser pointers, users must ensure that they follow the manufacturer’s safety instructions, 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.

BS EN – Safety of laser products. Equipment classification and requirements
A user’s guide originally included in Part 1 of the British Standard. Other British Standards sb 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 to 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 608251 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 changes. Ensuring a laser survey form is completed for each laser of Class 3R and above prior to 608251- 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 should be kept in the same area as the laser. The risk assessment 6082-51 procedures must be reviewed and if necessary revised at least annually or if sb are significant changes.
Ensuring risk assessments and laser survey forms for 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 survey. 6082-51 is the responsibility of the appropriate academic supervisor to address any such problems.
Em any recommendations made by the Head of Health and Safety for remedial action following the annual audit.
Assisting in fn 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 60285-1 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 dn 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.
