Čl. I

Government Regulation No. 361 / 2007 Coll., laying down conditions for the protection of health at work, as amended by Government Regulation No. 68 / 2010 Coll., Government Regulation No. 93 / 2012 Coll., Government Regulation No. 9 / 2013 Coll., Government Regulation No. 32 / 2016 Coll. and Government Regulation No. 246 / 2018 Coll., are amended as follows:

1. At the end of footnote 1, the sentences are added on a separate line:

"Directive (EU) 2017 / 2398 of the European Parliament and of the Council of 12 December 2017 amending Directive 2004 / 37 / EC on the protection of workers from the risks associated with exposure to carcinogens or mutagens at work.

Directive (EU) 2019 / 130 of the European Parliament and of the Council of 16 January 2019 amending Directive 2004 / 37 / EC on the protection of workers from the risks associated with exposure to carcinogens or mutagens at work. ';

2. Paragraph 18 (2), including footnote 28, reads:

"(2) If the results of the evaluation indicate that the use of the chemicals referred to in Article 16 (1) (a) cannot be replaced for technical reasons by a chemical or in accordance with the procedure referred to in paragraph 1, the employer shall ensure that their use or production is carried out, where technically feasible, in a technologically closed system. If the introduction of a closed system is not technically feasible, the staff member's exposure must be reduced to the lowest technically achievable level and the work carried out only in a controlled way28). The establishment of a controlled zone is not required for works that are carried out in the short term, that is less than 4 hours per shift. Furthermore, the establishment of a controlled zone is not required for outdoor work in the case of exposure to emission exhaust gases from diesel engines or the use of petroleum hydrocarbons when petroleum hydrocarbons are used to power combustion engines.

28) § 7 of Act No. 309 / 2006 Coll., as amended by Act No. 362 / 2007 Coll. '

3. In Article 21 (6) (j), the words "the scope of preventive care racing 'are replaced by the words" occupational medical services provided to the extent provided by the occupational health service provider'.

4. Paragraph 25 (9) reads as follows:

"(9) For risk factors, which are physical loads or working positions, the employer may include work in the second category on the basis of an expert evaluation carried out by the holder of the authorisation to investigate in the field of labour physiology under Section 83a (1) (i) of the Act on Public Health Protection (9). The professional evaluation shall include data on the nature of the work, the place of work, the time of work, the exchange rate, information on the handled material, the mode of work and rest during the work, the tools used, the sex of the employees and their rotation at individual posts and the photo documentation relating to the work environment, if any. The first sentence shall not apply if the exclusion of work from risk work for risk factors is a physical burden or a working position. If there is an occupational disease or a threat to occupational diseases in the workplace for a risk factor, the employer shall, within a period of 6 months from the date of recognition of an occupational disease or an occupational disease threat, measure that risk factor under the Public Health Protection Act (9). The measurement and evaluation of the local muscle load shall be as set out in Annex 5, Part B, to this Regulation. ';

5. Part of Annex No 2 to this Regulation And including the title reads:

„ČÁST A

Dust lists and their permissible exposure limits

1. The permissible exposure limit for total dust concentration (inhalable fraction) is known as PELc and for the respirable dust fraction PELr. Inflatable dust fraction means a set of particles of floating dust that can be inhaled by the nose or mouth. Respiratory fraction means the mass fractions of inhaled particles which penetrate into the part of the airway where there is no mascara epithelium and into the larvae according to Czech technical standard ČSN EN 1540 Exposure to the workplace - Terminology.

2. The permissible exposure limit of the dust mixture (PELs) with the different permitted exposure limits shall be determined by calculating the permissible exposure limit of each dust according to the formula:

PELs =% x1100 × PEL1 +% x2100 × PEL2 +....... +% xn100 × PELn-1

where

PELs is a PEL mixture,

PEL1 to PELn is the exposure limit of the individual substances 1 to n,

% x1 to% xn is the weight of each substance from 1 to n as a percentage.

3. If the weight of the individual components in flydust cannot be reliably determined, the permissible exposure limit shall be determined according to the value applicable to the substance with the lowest permissible exposure limit.

In the event that the weight of the individual components in flydust cannot be reliably determined, PELs shall be determined according to the value applicable to the substance with the lowest permissible exposure limit.

4. If the powder contains a fibrogenic component, its respirable fraction and the concentration of the fibrogenic component shall always be determined. If the respiratory fraction contains more than 1% of the fibrogenic component, its PELr must not exceed the values given in Table 1. The permissible exposure limit shall be considered as complying with both PELr for the fibrogenic component and PELc for the dust type.

5. If dust contains less than 1% crystalline SiO2 and does not contain asbestos, it shall be considered as dust having a predominantly non-specific effect.

6. For dust having a predominantly non-specific effect PELc = 10 mg.m-3

7. The permissible exposure limit shall not take into account the potential sensitising effects and potential content of micro-organisms in dust.

Explanatory notes to Table 1:

(a) dust containing more than 1% of the fibrogenic component shall be regarded as fibrogenic.

b) Fr is the content of the fibrogenic component in the respiratory fraction as a percentage. The fibrogenic component is quartz, Kristobalite, tridymite or gamma-aluminium oxide.

(d) In the presence of a numerical concentration of respiratory fibres (so-called WHO fibres with a length of more than 5 μm, a diameter of less than 3 μm and a ratio of length to diameter of more than 3: 1) in the working air, the permissible exposure limit for asbestos must be complied with.

(e) For a chemical, carcinogenic effects cannot be excluded.

(a) Where iron alloys contain a higher proportion of metals for which they are set by the permissible exposure limit, dust shall be assessed even according to the permissible exposure limit of these metals. A condition whereby both the PELc for iron alloy and the permissible exposure limit for individual metals are respected shall be considered to comply with the permissible exposure limit, the lowest exposure limit being the limit. Alloys of non-ferrous metals shall be assessed in terms of dust according to the permissible exposure limit of the individual metals present in the alloy, the component of which is the lowest exposure limit being decisive.
