Laser pointers Misuse of laser pointer can cause damage to eyes. For use of Class 3B and 4 lasers in industry, research and education the key measures to be considered are: Of most bss to the end user is the laser classification scheme it defines.
The guidance also states that lasers which would not otherwise be accessible, for example in a Class 1 product, ns which are exposed during manufacture or repair of the equipment may also be ‘hazardous’ lasers for the duration of that activity.
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. 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. What the standard is not, is a user guide for laser safety.
Advising officers in charge of design and construction of new buildings and the modification of existing buildings on matters affecting laser safety.
Ensuring that information and precautions identified by the risk assessment, are available to laser users. The HSE guidance sets out the control measures to be considered on a case-by-case basis to reduce the risk of harm to the eyes and skin of workers to as low as is reasonably practicable.
Equipment classification and requirements IEC Equipment classification and requirements. However, in some cases, other associated risks from use of the equipment may be more hazardous such as heat, dust and fumes.
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.
It is this standardised scheme that indicates the risk involved in using the product, and hence, what precautions should be taken when the product is being used. Class 1 – Safe under reasonably foreseeable conditions of operation. Misuse of laser pointer can cause damage to eyes. The reference EN Laser pointers are not to be modified in any way.
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 2M – As Class 2 but not safe when viewed with optical aids such as eye loupes or binoculars. It is this product safety standard that defines what makes a laser applicable to a particular class.
LVR Optical – Laser and Optical Radiation consultants
Class 1M – As Class 1 but not safe when viewed with optical aids such as eye 68025-1 or binoculars. Class 4 – Eye and skin damage likely form the main laser beam and reflected beams. Addressing any recommendations made by the Head of Health and Safety for remedial action following the annual audit. These lasers may cause fires. Assisting in risk assessment and drawing up of written procedures for use of all lasers in their Departments.
Guidance for laser displays and shows http: Other British Eh in this series cover laser processing machines, optical fibre communication systems OFCSand laser displays and 6082-1. The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being maintained by the editorial teams at NBS.
Supersedes BS EN They are therefore included in the main provisions of this Code. The risk assessment and 608225-1 must be reviewed and if necessary revised at least annually or if there are significant changes.
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. 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.
This document defines things such as the 3m separation distance etc. It is the responsibility of the appropriate academic supervisor to address any such problems. If a manufacturer is claiming compliance with EN Class bss – Safe without viewing aids, lasers are designed explicitly for contact applications to the skin or non-ocular tissue. They give examples of Class 1M, 2 or 2M lasers, for example some low power laser pointers in surveying tools. Again there may be more recent versions of the document.
It is however useful for end users to be aware of though, as it allows them to check with their supplier that the product being purchased is compliant and legal to use.
Their committees work with the manufacturing and service industries, government, businesses and consumers to facilitate the production of British, 60825-11 and International standards.
Registrations must be made prior to first use and then updated for changes. The safety standard also bss what safety features must be included with each type of product based on the classification. 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.
It is primarily a product safety standard that manufacturers must adhere to. 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. Want access to British Standards? This document Older versions.
