Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2016, Vol 32, Issue 1
Abstract
In 2015, the Commission met at four sessions, in which 10 documentations for recommendedexposure limits of chemical substances were discussed. Moreover, the Commission discussed: – draft text of the MAI (NDN) for electromagnetic fi elds in the context of the implementationof the Directive 2013/35/EU of the European Parliament and of the Council of 26 June 2013 on the minimum health and safety requirements regarding the exposure of workers to the risks arising from physical agents (electromagnetic fi elds) (20th individual Directive within the meaning of Article 16(1) of Directive 89/391/EEC) and repealing Directive 2004/40/EC (OJ L 179, 29.6.2013, p. 1) and – a proposal to amend provisions regarding the dust listed in section B of Annex 1 to the Regulation of the Minister of Labour and Social Policy of 6 June 2014.The Commission suggested to the Minister of Labour and Social Policy the following changes in the list of MAC values:– adding two new chemical substances to the list of MAC values: 3,3’-dimethoxybenzidine (CAS: 119-90-4, Carc. 1B), ethyl carbamate (CAS: 51-79-6, Carc. 1B) – changing MAC values for 8 chemicals: chromium(VI) compounds (as Cr(VI), 1,4-dichlorobenzene (CAS: 106-46-7), 2-ethylhexane-1-ol(CAS: 104-76-7), diethyl phthalate (CAS: 84-66-2), n-butyl acetate (CAS: 123- -86-4), sec-butyl acetate (CAS: 105-46-4), isobutylacetate (CAS: 110-19-0) and lithium hydrogen (CAS: 7580-67-8)– introduction in Annex 1 in Part A of the list „Chemicals” the dust agreed at the 80th meeting of the Interdepartmental Commissionfor MAC and MAI on 23 September 2015. For wood dust, the Commission adopted a simplifi ed recording, leaving onlydust oak and beech, whose carcinogenic effects are proven epidemiologically, until new research fi ndings in this area are published and a new document is developed: (a) the wood dusts – the inhalable fraction NDS (TWA): 4 mg/m3 ; (b) wood dusts ofbeech and oak – the inhalable fraction NDS (TWA): 2 mg/m3– removal of „Comments” currently listed in Annex 1 for the list in Part B. Occupational Exposure Limits for 1,2-dimethoxyethane(NDS (TWA): 10 mg/m3 NDSCh (STEL): not determined) and propane-1,2-diol (propylene glycol - inhalable fraction and vapours; NDS (TWA): 100 mg/m3 NDSCh (STEL): not determined) proposed by the Group of Experts of Chemical Agents were adopted by the Interdepartmental Commission for MACs and MAIs at 81st meeting on 12 November 2015, but will beapplied to the regulation of the minister responsible for labour affairs after developing methods for the determination of their concentrations in the working environment in 2016. Four issues ofthe Principles and Methods of Assessing the Working Environment were published in 2015. The following were published: 11 documentation of occupational exposure limit, 8 methods of determining chemical concentrations in the working environment, 5 articles, procedure for measuring ultrasonic noise, report on the activities of the Interdepartmental Commission for MAC and MAIin 2014 and indexes of documentations, methods and articles published in 2000–2015. Three sessions of the Commission are planned for 2016. MAC values for 13 chemicals substances will bediscussed at those meetings.
