Exhibition of Motives

This Law, in transposition of Directive No 2006 /25/CE of the European Parliament and of the

Council of April 5, 2006 adopts various provisions to protect the

workers in situations of exposure to risks due to artificial optical radiation, the

what can have effects on the safety and health of workers and provoke,

notably, eye and skin lesions.

The protection against the risks of artificial optical radiation follows the model of the protection

against the risks derived from other physical agents, namely vibrations and noise.

Employers must carry out the assessment of risks of exposure to optical radiation

artificial, in accordance with international standards and recommendations and use all the

means available to eliminate such risks or, if this is unfeasible, reduce them to a minimum

possible.

In the prevention of risks, they assume a central place, as the said Directive points out, the

design and installation of the sites and workstations and the choice of equipment of

work that are sources of optical radiation. Such equipment, when they are

manufactured in accordance with the applicable safety standards and have maintenance

proper periodical, provide an additional security guarantee for the

workers.

Are certain limit values of exposure that employers must ensure that

are not exceeded in any circumstance, without prejudice to provide that

the exposure of workers to artificial optical radiation, if it cannot be eliminated, be

the shortest possible.

CHAIR OF THE COUNCIL OF MINISTERS

Proposal for Law No. 19 /XI/1.

Prevention is also based to a large extent on information, consultation and training

of the employees and their representatives on the various aspects related to the

man-made optical radiation, its risks and the measures to be taken to prevent them.

Prevention is still based on regular monitoring of the health of workers exposed to

man-made optical radiation and, depending on its results, in the protective measures

additional or corrective ones that should be applied.

The present law was published for public appreciation in the Separata of the Bulletin of the Work and

Employment n ° 1 of January 7, 2010 having been weighted comments by associations

trade union and employers.

The self-governing bodies of the Autonomous Regions were heard.

Thus:

Under the terms of the paragraph d) of Article 197 (1) of the Constitution, the Government presents to the

Assembly of the Republic the following proposal for a law:

Article 1.

Object and scope

1-A This Law sets out the minimum requirements for protection of workers

against the risks to health and safety due to exposure, during the work, the

optical radiation from artificial sources, transposing Directive No 2006 /25/CE of the

European Parliament and of the Council of April 5, 2006 on prescriptions

Health and safety minimum workers ' exposure to risks

due to physical agents (artificial optical radiation).

2-A This Law shall apply to all activities of the private, cooperative and

social, central, regional and local public administration, public institutes and the

too many legal persons of public law, as well as workers on account

own.

national or international guidelines available and scientifically substantiated, up to

that standards or recommendations are adopted from the European Union.

ANNEX I

(as referred to in Article 3 (1) and Articles 5 and 7)

Non-coherent optical radiation

The exposure values to the relevant optical radiation from the biophysical point of view are

determined using the formulae mentioned below. The formulas to be used

depend on the range of radiation emitted by the source and the results should be compared

with the corresponding exposure limit values (VLE) indicated in Table 1.1. To

a given source of optical radiation there may be more than an exposure value, and

corresponding exposure limit, relevant.

Note 1:

The range of 300 a to 700 nm covers part of the UVB, all UVA and most of the visible radiation; the risk associated with it is commonly known at risk of "blue light".

The blue light, in a restricted sense, covers only the range of approximately 400 a to 490 nm.

Note 2:

For a constant clamping of very small sources with a angular position <11 mrad, LB can be converted into EB. As a rule, this applies only to instruments

ophthalmological or to a stabilized eye during an anaesthesia. The maximum clamping time of the look is given by: tmax = 100 / EB, being EB expressed in W m-2. Given the

eye movement during the normal functions of the vision, such does not exceed 100 s.

ANNEX II

(as referred to in Article 3 (2) and Article 5)

Laser optical radiation

The values of exposure to relevant optical radiation from a biophysical point of view are

determined using the formulae mentioned below. The formulas to be used

depend on the wavelength and the duration of the radiation emitted by the source and the

results should be compared with the corresponding exposure limit values

(VLE) indicated in tables 2.2-2.4. For a given source of laser optical radiation can

there is more than one exposure value, and corresponding exposure limit, relevant.

The coefficients used as calculation tools in tables 2.2-2.4 are listed in the

frame 2.5 and corrections for repetitive exposure are shown in Table 2.6.

A-In case there are two limits to the wavelength of the laser, the most restrictive one applies.

B-Se 1400 <λ <105 nm: aperture diameter = 1 mm for t <0.3 s and 1.5 t0, 375 mm for 0.3 s <t <10 s: if 105 <λ <106 nm: aperture diameter = 11 mm.

C-Due to lack of data for these conditions of duration and wavelength, CIPRNI recommends the employment of the limits of irradiance to 1 ns.

D-The frame presents values for a single laser pulse. In case of multiple laser impulses, the durations of the laser impulses, if the impulses occur in a Tmin range (see

frame 2.6), should be added and the resulting temporal value should correspond to t in the formula: 5.6 * 103 t0, 25.

B-For small sources that subunderstand an angle of less than or equal to 1.5 mrad, the visible dual limit E from 400 nm to 600 nm reduces to the thermal limits for 10 <<T1 and to the limits

photochemicals for longer durations. The values of T1 and T2 are listed in Table 2.5. The limit of the photochemical risk for the retina may also be expressed as the integrated radiance in

order to time G = 106 CB [J m-2 sr-1] for t> 10 s up to t = 10000 s and L = 100 CB [W m-2 sr-1] for t> 10000 s. For the measurement of G and L it should use γm as a mean field of view. The

official border between the visible rays and the infrared is 780 nm second to the CIE definition. The column with the names of the wavelength ranges is intended solely to give a

best panoramic to the user. (The G notation is used by the CEN: the Lt notation is used by CIE: the Lp notation is used by the CEI and CENELEC.)

C-For wavelengths 1400-105 nm: diameter of aperture = 3.5 mm: For wavelengths 105-106 nm: diameter of aperture = 11 mm

D-For the measurement of the exposure value the input of γ is defined as follows: If the (angular position of a source)> γ (maximum conical angle, indicated in the straight parentheses in the

corresponding column) then the field of view of the γm measurement should be the given value of γ. (If it were used a larger field of view of the measurement, then the risk would be overassessed).

If α <γ then the field of view of the γm measurement should be sufficiently large to fully involve the source but on the other hand it is not limited and it may be greater than γ.

Table 2.6

Correction for repetitive exposure

Each of the following three general rules should be applied to all exhibitions

repetitive arising from laser systems of repetitive or scanning impulses.

1. The resulting exposure of a single thrust of a series of impulses shall not exceed

the limit value of exposure of a single impulse with this pulse duration.

2. The resulting exhibition of a group of impulses (or impulse subgroup in a series)

issued in time t should not exceed the exposure limit value for t time.

3. Exposition resulting from a single impulse in a group of impulses shall not exceed the

limit value of exposure of a single impulse multiplied by the correction factor

cumulative thermal Cp=N-0, 25, where N is the number of impulses. This rule applies

only to exposure limits for protection against thermal lesions, where all the

impulses emitted in less than Tmin are treated as a single impulse.
