Regulation 38
of Radiation Protection (Non-Ionising Radiation) Regulations
Regulation 38
Requirements for labelling of lasers
Subregulation 1
Every laser shall carry a label or labels in accordance with the requirements of this paragraph. The labels shall be permanently fixed, legible and clearly visible during operation, maintenance or service, according to their purpose. They shall be so positioned that they can be read without the necessity for human exposure to laser radiation in excess of the AEL for Class 1. If the size or design of the apparatus makes labelling impractical, the label should be included in the user information or on the package.
Subregulation 2
Every Class 1 laser shall have affixed an explanatory label bearing the following words:“CLASS 1 LASER PRODUCT”.
Subregulation 3
Every Class 2 laser shall have affixed a warning label as set out in the Fourth Schedule.
Subregulation 4
Every Class 3a laser shall have affixed a warning label as set out in the Fourth Schedule.
Subregulation 5
Every Class 3b laser shall have affixed a warning label as set out in the Fourth Schedule.
Subregulation 6
Every Class 4 laser shall have affixed a warning label as set out in the Fourth Schedule.
Subregulation 7
Every Class 3b and Class 4 laser shall have affixed a label close to each aperture through which laser radiation in excess of the AEL for Class 1 or Class 2 is emitted. The label shall bear the following words:“LASER APERTURE or AVOID EXPOSURE — LASER RADIATION IS EMITTED FROM THIS APERTURE”.
Subregulation 8
Every connection product, except a product specified in Class 1, shall be described on the explanatory label as shown in the Fourth Schedule by statements of the maximum output of laser radiation, the pulse duration (if appropriate) and the emitted wavelength or wavelengths.
Subregulation 9
Every connection, panel of a protective housing and every access panel of a protective enclosure which when removed or displaced permits human access to laser radiation in excess of the AEL for Class 1 shall have affixed a label bearing the following words:“CAUTION — LASER RADIATION WHEN OPEN”.In addition, such label shall bear the following words:
“DO NOT STARE INTO BEAM”.if the accessible radiation does not exceed the AEL for Class 2.(b) “DO NOT STARE INTO BEAM OR VIEW DIRECTLY WITH OPTICAL INSTRUMENTS”.if the accessible radiation does not exceed the AEL for Class 3a.(c) “AVOID EXPOSURE TO BEAM”.if the accessible radiation does not exceed the AEL for Class 3b.(d) “AVOID EYE OR SKIN EXPOSURE TO DIRECT OR SCATTERED RADIATION”.if the accessible radiation exceeds the AEL for Class 3b at any wavelength.
Subregulation 10
Appropriate labels shall be clearly associated with each safety interlock panel which may readily be defeated and which will then permit human access to laser radiation in excess of the AEL of Class 1. Such labels shall be visible prior to and during interlock override and be in close proximity to the opening created by the removal of the protective housing and shall bear the following words:“CAUTION — LASER RADIATION WHEN OPEN AND INTERLOCKS DEFEATED”.
Subregulation 11
If the output of the laser is outside the wavelength range 400 nm to 700 nm, the explanatory label shall be modified to read “Invisible laser radiation”, or if the output is at wavelengths both inside and outside this wavelength range, to read “Visible and invisible laser radiation”.
Subregulation 12
A laser is to be treated as complying with all the relevant requirements in this regulation if —
it is classified in accordance with any standard specified in the Seventh Schedule; and
it complies with the requirements for the labelling of lasers in that standard that correspond to the relevant requirements in this regulation.
