4 Laser safety regulations Laser Safety: European Norms Laser safety regulations Laser safety regulations have the purpose of defining the necessary guidelines to every operator working with lasers. They derive from theoretical and experimental activities carried out for several decades, and constantly updated, in the domain of laser-tissue interaction and laser hazard evaluations in animals and in humans. The results of this huge amount of work, and of the combined effort of scientists, are sets of indications of how, and how much, the operator should protect himself from laser injuries. The use of laser protection eyewear is of primary importance in this context, being the eye the most critical organ in relation to laser injury. Thus, most of the existing norms and guidelines are for the major part intended to deal with eye protection. Countries have evolved differently towards Norms in the domain of laser safety. Therefore, different Norms exist for the two major western continents, Europe and USA. These differences affect the marketability of eyewear products in the different areas, or in third countries that may adhere to either one or the other of the two. In this section we deal with the outline of the most common Norms, starting from the one valid for Europe. Laser Safety: European Norms The current European Norms concerning Laser Safety are basically Norms cin Europe there is a second criterion to be taken into consideration in addition to the Optical Density. This is the power/energy density (i.e. the power/energy per area of the laser beam). Diffuse viewing is not allowed: therefore all laser safety glasses must shield the operator against a direct hit of the laser beam. Protection with Optical Density alone is not sufficient when the material of the eyewear will not be able to withstand a direct hit. The regulations that follow are here called the norm, but they actually are legal requirements and enforceable. Other legal requirements (e.g. the regulations for industrial safety as well as the medical equipment regulations) refer to them as well.

5 EN - EN - According to the most recent classification norms (EN -, November ), major emphasis has been given to the so called accessible emission limits (AEL s). AELs are defined as the exposure levels which are inherently safe for the eye. Lasers, therefore, have been classified into several hazard classes, depending on the AEL s. The classification scheme is a measure of the laser, or the laser system, to produce injuries to the personnel. The table below shows the applicable classification of the different lasers. M M R B The radiation emitted is not dangerous under foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing The radiation emitted is not dangerous when used without optical instruments, however it may become dangerous if used in combination with optical instruments. They are generally lasers emitting between. and nm The radiation emitted (between and nm) is not dangerous due to aversion responses including the blink reflex The radiation emitted is not dangerous due to aversion responses including the blink reflex when used without optical instruments, however it may become dangerous if used in combination with optical instruments (between and nm) The radiation from these lasers, operating between. and,, nm, exceeds the maximum permissible exposure values (MPE s) for intrabeam viewing. AELs are within five times those of Class between and nm, and within times those of Class elsewhere. The risk is slightly lower than that of class B Direct laser view is dangerous. Diffuse reflections are not regarded as dangerous Direct view is dangerous. Also diffuse radiation can be dangerous. Additionally, there is danger of fire and danger to the skin There is no need for any protection equipment There is no need for any protection equipment, if used without optical instruments There is no need for any protection equipment There is no need for any protection equipment, if used without optical instruments Dangerous to the eyes, safety glasses are recommended Dangerous to the eyes, safety glasses are mandatory Personal safety equipment is necessary (glasses, screens

6 EN EN Requirements in relation to optical density EN EN requires that laser safety eyewear provide sufficient optical density to reduce the power of a given laser to equal to or less than the listed Maximum Permissible Exposure levels (MPE). It allows specification according to optical densities in extreme situations, but recommends the use of EN with a third party laser test. In neither standard is a nominal hazard zone allowed, the only consideration is protection against the worst-case situation i.e. direct laser radiation. EN EN () contains the requirements that the eye protection equipment should have in order to be safe for the laser operator. The requirements are of two types: (i) Requirements related to Optical Density (), (ii) Requirements related to Stability to laser radiation, and (iii) Requirements related to Minimum transmission in the visible. Requirements in relation to optical density Optical density (related to spectral transmission) is a very important parameter, which expresses the laser power/energy exiting the filter as a fraction of the power/energy entering into it. Optical density is a Wavelength-dependent parameter and is defined as: P = log in (λ) = -log (T(λ)) [ P out (λ) ] where Pin(L) is the power at the input of the filter Pout(L) is the power transmitted and exiting the filter, T(L) is the transmission factor. The following table specifies the relationship between optical density and transmission. In the table, for each value of the Optical Density the first row expresses the transmission in decimal notation, the second row expresses the transmission in exponential notation.

7 Stability to laser radiation Minimum transmission in the visible... T (decimal)..... T (expon.) EN requires that laser eyewear is labelled with a number expressing the maximum transmission factor for a given set of wavelengths, and that this maximum transmission value (minimum Oprical Density) value should never be exceeded under test regime. The above requirements hold for both filters and frames. Stability to laser radiation This is a requirement that is not present in the US Norm. It states that the filter and the frame, labelled with a given value of transmission/optical density should resist to a direct hit of laser radiation of specified power/energy and duration, and should not lose, during the hit, their blocking properties. Minimum transmission in the visible Transmission of the eyewear in the visible should be, according to the Norm, at least % (integrated over the whole spectrum), unless a recommendation for a higher value is issued to the manufacturer.

8 Considerations in relation to the adherence to the norms Considerations in relation to the adherence to the norms A consequence of the combination of the two requirements is that, if a filter showing a transmission factor of -, but only passes the stability test for a filter with transmission factor of -, it should be labelled for the second. Therefore, especially in the light of amount of power/energy that the filter/frame combination must withstand, stability is a far more strict requirement than transmission, especially with high values of optical densities. The ensemble of above requirements is summarized in the Table below. SCALE NO.

9 Filter/Frame coding The conditions for testing are summarized in the Table below Pulse durations and number of pulses for eyewear testing according to EN TESTING LASER TYPE CONDITIONS FOR TYPICAL LASER TYPE PULSE LENGHT (S) NUMBER OF PULSES D continuous wave laser I pulsed laser - to - R Q-switched pulsed laser - to - M modelocked pulsed laser < - Filter/Frame coding Every eyewear is a unique component according to Univet s policy. The marking code is expresely intended to caratterized the combination of the two items, to accomplish the norm s requirement. A code is permanently marked in every filter/frame combination and holds valid for the combination of the filter of the frame. A typical marking code of an eyewear has the following marked coding R L The following applies: The notation R identifies the pulse duration range for which the eyewear is intended to be used (q-switched regime) and with which it has been tested; The notation identifies the wavelength (wavelength ranges are specified with the notation Min- Max), in this case Nd:YAG monochromatic laser radiation; The notation L identifies the test conditions according to EN : the eyewear should have resisted without transmission degradation to at least pulses of duration - to - seconds and with energies of at least.joulse/m.

10 EN US Laser Safety Norms EN EN is limited to the family of glasses for laser alignment. These glasses are intended to limit the incident power of a laser to the power that a Class laser (see ) would have. According to EN, alignment glasses must be able to resist under exposure of the laser radiation for at least seconds (CW) or pulses (pulsed mode). Requirements for the testing of alignment glasses accordino to EN SCALE NUMBER ACCORDING TO EN R R R R R CW LASERS AND PULSED LASERS HAVING PULSE LENGTHS >X-S MAX. POWER IN W.. PULSED LASERS HAVING WITH PULSE LENGTHS BETWEEN - AND -S MAX. PULSE ENERGY IN J US Laser Safety Norms Laser safety in the USA is based on the Norm ANSI Z. This norm requires a specification of the safety equipment according to (optical density). ANSI Z allows a Nominal Hazard Zone (NHZ) to be determined by the laser safety officer. Outside of the NHZ, diffuse viewing eyewear is allowed. Most Asian countries refer to this regulation. Australia has recently adopted new laser safety regulations, which are based on the European laser safety regulations (EN /EN ).
