Code of Practice – Laser Safety
Many items of scientific equipment are Class 1 lasers and may also be regarded as ‘safe’, for example spectrophotometers and particle sizers. Supersedes BS EN Of most importance to the end user is the laser classification scheme it defines. 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. They are responsible for.
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.
They give examples of Class 1M, 2 or 2M lasers, for example some low power laser pointers in surveying tools. Advising officers in charge of design and construction of new buildings and the modification of existing buildings on matters affecting laser safety. Guidance for laser displays and shows http: The ‘light’ produced by a laser, a form of non-ionising radiation, has a unique combination of characteristics that distinguishes laser radiation from all other light sources.
Free to use BIM project management tool provides step-by-step help to define, manage and validate responsibility for information development and delivery at each stage of the asset life cycle in level 2 BIM projects. Again there may be more recent versions of the document.
BS EN – Safety of laser products. Equipment classification and requirements
It is the responsibility of the appropriate academic supervisor to address any such problems. This document defines things such as the 3m separation distance etc.
Addressing any problems notified by the Laser Safety Supervisor that arise from the annual survey. Class 1 – Safe under reasonably foreseeable conditions of operation. They are therefore included in the main provisions of this Code.
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. Lasers emit radiation as narrow concentrated beams of light, not necessarily visible to the human eye. Ensuring that information and precautions identified by the risk assessment, are available to laser users.
Assisting in preparing and keeping up to date University Policies and Codes of Practice relating to laser safety. Class 4 – Eye and skin damage likely form the main laser beam and reflected beams. It is primarily a product safety standard that manufacturers must adhere to.
Equipment classification and requirements. Lasers come in various forms and have many uses at work, in the home and for leisure: The reference EN 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. The risk assessment and procedures must be reviewed and if necessary revised at least annually or if there are significant changes.
The HSE guidance gives examples of ‘hazardous’ lasers that present a ‘reasonably foreseeable’ risk of harming the eyes and skin of workers 60285-1 where control measures are needed.
Class 1C lasers are engineered to be ocular safe. It is this product safety standard that defines what makes a laser applicable to a particular class. Class 2 – 6085-1 beams only the eye is protected by the aversion responses, including the blink reflex and head movement. Also known as IEC 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. Class 1M – As Class 1 but not safe when viewed with optical aids such as eye loupes or binoculars.
Under this Code of Ba, only Class 1 or 2 lasers may be used for demonstration, display or entertainment.
However, in some cases, other associated risks from use of the equipment may be more hazardous such as heat, dust and fumes. 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.
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.
Members of staff wishing to use a Class 3 laser pointer must first consult the University Laser Safety Adviser.
Other things EN Equipment classification and requirements IEC 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 HSE guidance sets out the control measures to be considered on a case-by-case basis to reduce the 608825-1 of harm to the eyes and skin of workers to as low 60825-11 is reasonably practicable. These lasers may cause fires. 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.
BS EN 60825-1:2014
These products may contain a higher powered laser as an embedded component but it is not accessible in normal use. What the standard is not, is a user guide for laser safety.
Class 2M – As Class 2 but not safe when viewed with optical aids such as eye loupes or binoculars. B 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.
Using any Class 3B or Class 4 product requires careful planning and operation by a person bx is knowledgeable of hs risk, and what precautions should be taken.
Misuse of laser pointer can cause damage to eyes. The highest risk category defined in the standard is Class 4, which pose a serious risk of eye damage from both direct and indirect reflections, is able to burn skin, and act as an ignition source for materials.
Liaising with the Head of Health and Safety and Rn Occupational Health Service on matters relating to medical examinations and health of registered laser workers. For use of Class 3B and 4 lasers in industry, research and education the key measures to be considered are:.
