Comfort is an issue that has gained relevance within the aeronautical industry due to the necessity of manufacturers and airline companies of differentiating themselves in a market that has become more and more competitive each day. This study's aim is to analyze the comfort/discomfort of passengers, based on the analysis of the activities performed in the aircrafts' cabin during real flights, in order to create ergonomics requirements and a methodology of comfort analysis. The study has been performed during domestic commercial flights, and the adopted data collection techniques have been: the application of 219 questionnaires to passengers, 44 registrations of postures and actions through filmings and 12 semistructured interviews. The method has made possible the reconstruction of the user's action course in performing activities in real flight situations, and the calculation of the area occupied by the passenger during his or her actions. The integrated analysis of the results corroborates data from previous studies in which both the space made available to each passenger and the activity performed interfere in their perception of comfort. From this study it has been concluded that the method constitutes itself as an innovative tool within the process of aircrafts' cabins project enabling the calculation of the action space based on the reconstructed course.

This article presents results obtained from some ergonomics intervention in the project for the conception of aircraft´s cabins. The study's aim is to analyze the contribution of the method adopted in the passengers' activities analysis in reference situations, real-use situations in aircraft´s cabins, applied to analyze typical activities performed by people in their own environment. Within this perspective, the study shows two analyses which highlight the use of electronic device. The first analysis has been registered through a shooting filming in a real commercial flight. In the second one, the use is developed within the domestic environment. The same method has been applied in both contexts and it is based on activity analysis. Starting with the filming activity, postures and actions analysis, self-confrontation interviews, action course reconstruction and elaboration of postures envelopes. The results point out that the developed method might be applied to different contexts, evincing different ways of space occupation to meet human personal needs while performing an activity, which can help us with the anticipation of the users' needs, as well as indicate some innovation possibilities.

During the first step-Basic Characterization-BC-the appraiser collects available information to allow reliable estimates of the exposure of the workers and to take the decision whether or not to perform exposure measurements. The second step, or 'Initial Assessment-IA', consists of performing at least 3 (screening test) to 6 representative exposure measurements for the workers of each SEG, in order to demonstrate by using a statistical test whether less than 5% of exposures in the SEG exceed the OELV (compliance). In a third step and based on IA results, a program of 'Periodic Reassessment-PM' determines time intervals ranging from 1 to 3 years for performing new measurements, depending of the levels of exposure. This is based on the assumption that no major changes (e.g. process, RMM, quantities and nature of chemicals) have occurred during this period.The new EN-689 also takes into consideration simultaneous exposure to several chemicals, and workshift durations higher than 8 hours. The informative annexes give recommendations to determine for example: sampling duration, statistical distribution of exposure measurements results and treatment of representative results lower than the limit of quantification (LoQ).The new EN 689 is a helpful tool, especially when expertise/science/evidence does not help in the decisions to protect workers exposed to chemicals. 1717b REGULATORY ADVANCES IN CONTROLLING HAZARDOUS SUBSTANCESBridget Ginnity. 10.1136/oemed-2018-ICOHabstracts.565The REACH and CLP Regulation have given rise to a rich source of information on chemicals and introduced new mechanisms for regulatory control of hazardous chemicals. Occupational health and hygiene practitioners (OHPs) can contribute to the regulatory decision making and can use the increased information and regulatory control to promote the safe use of chemicals in the workplace.The registration element of REACH has received most attention to date and the final registration deadline under the REACH Regulation for chemical substances manufactured or imported into Europe is imminent, 31 st May 2018. The registration process generates an immense amount of information on the hazardous properties of substances and on how they can be used safely. Some of this information is provided with safety data sheets, such as DNELs (Derived No Effect Levels) and exposure scenarios. Much more information, including toxicological data, is available on the website of ECHA, the European Chemicals Agency.REACH and the CLP Regulation provide for the regulatory control mechanisms of authorisation, restriction and harmonised classification and labelling. These mechanisms are intended to protect workers, consumers and the environment. OHPs can engage with these processes to ensure that decisions are made with reliable, up-to-date information on what is happening in the field. By knowing the regulatory status of chemicals used on site, OHPs can ensure regulatory compliance and promote the safe use of chemicals in their company. 1717c BIOLOGICAL MONITORING AND THE USE OF...
