Laser Warning Labels to Current Laser Safety Standards
Standard Labels according to European and International Standard EN 60825-1 and IEC 60825-1
These are required on all lasers above Class 1
These are required on all Class 3R, Class 3B and Class 4 lasers
If your laser product contains a laser which is Class 1 even when all housings have been stripped away then it is exempt from the requirements of EN / IEC 60825-1, including labelling requirements.Otherwise your laser will need a Classification label.
PROTECTIVE HOUSING LABELS
These are required on all panels or connections which when removed, opened or displaced will give access to radiation in excess of Class 1. The class of this label is determined by the class of the laser radiation accessible once the panel is opened (eg a panel on a Class 1 laser product, which when removed gives access to Class 3B laser radiation will require a Protective Housing Class 3B label).
INTERLOCKED HOUSING LABELS
These are required on all interlocked panels which when opened will give access to radiation in excess of Class 1 when the Interlock® is overridden. The label should be fixed in close proximity to the opening and must be visible prior to and during Interlock® override. The class of this label is determined by the class of the laser radiation accessed once the panel is opened and the Interlock® overridden (eg an interlocked panel on a Class 1 laser product, which when opened and the Interlock® overridden gives access to Class 4 laser radiation will require an Interlocked Housing Class 4 label).
INVISIBLE / VISIBLE AND INVISIBLE RADIATION WARNINGS
Where the laser radiation is invisible, the ‘invisible radiation’ versions of Classification, Protective Housing and Interlocked Housing labels should be used.Where the laser radiation is both visible and invisible, the ‘visible and invisible’ versions of Classification, Protective Housing and Interlocked Housing labels should be used.
PRODUCT INFORMATION LABELS
These are required for all laser products exceeding Class 1. When used in conjunction with classification labels these need only contain the following:
- Maximum output power or energy
- Pulse duration (if appropriate)
- Number and publication date of standard to which the product is classified
Alternatively we can supply Blank labels (listed above) for you to write or print on. These are particularly of use when only a small number are required.
Standard Labels for Laser Laboratory / Operating Theatres
Generally people use the following:
Usually the larger ones such as 150 x 150 or 200 x 200 mm
Use the class appropriate to the highest class of laser which is used in the room
LARGE SHATTERPROOF WARNING NOTICE
Can be fitted to a door using double sided tape, or drilled and screwed or hung up and turned round as required.
Alternatively you can use Laser Controlled Area labels or Illuminated Laser Warning signs which indicate the status of the laser. These are also very often used as administrative control to avoid personnel entering a room while a laser is in operation.
Standard Labels according to 21 CFR 1040.10 (USA/CDRH)
The FDA’s Laser Notice 50 states that the FDA will now accept IEC classification and labelling. Therefore, for the US market, manufacturers can use the same labels as are shown in the section above on European and International Standard Labels. However, for those manufacturers wishing to use the distinctive CDRH labelling, this is outlined as:
Classification, product information and the laser warning symbol labels must be combined into one label.
This means that these labels are all custom made. Contact our sales department for a quotation.
PROTECTIVE HOUSING AND INTERLOCKED HOUSING LABELS
The wording of these is slightly different to the EN / IEC labels, notably in the use of the word ‘Danger’ in place of ‘Caution’.
Aperture labels must be located at all apertures that emit laser radiation. In some cases, only apertures which exceed Class 1 levels are required to be labelled.
