Warren, N.D. (author), Marquart, H. (author), Christopher, Y. (author), Laitinen, J. (author), van Hemmen, J.J. (author), TNO Kwaliteit van Leven (author)The regulatory risk assessment of chemicals requires the estimation of occupational dermal exposure. Until recently, the models used were either based on limited data or were specific to a particular class of chemical or application. The EU project RISKOFDERM has gathered a considerable number of new measurements of dermal exposure together with...article 2006

Kuijt-Evers, L. (author)The relationships of objective measurements (contact pressure and productivity) with subjective experienced comfort and discomfort in using hand saws was examined. Professional carpenters evaluated five different hand saws. The pressure-time integral during the static pressure measurement (beta = –0.24, p<.01) was highly related to comfort and...conference paper 2005

(author), TNO Kwaliteit van Leven (author)The aim of this study was to investigate the relationship between psychosocial work characteristics and neck and upper limb symptoms and to examine to what extent this relationship could be explained by other risk factors. Data were used from a prospective cohort study in a working population, with a follow-up period of 3 years. The 3-year...article 2005

Little is known of the preventive effects of physical activity in leisure time on neck and upper limb symptoms. Methods. A cohort of 1742 employees was selected from a prospective cohort study with a follow-up period of 3 years. Independent variables were sporting activities and physically active commuting. Outcome measures were neck...article 2005

(author), TNO Kwaliteit van Leven (author)The aim of the study was to identify predictors of comfort and discomfort in using hand tools. For this purpose, the comfort questionnaire for hand tools (CQH) was developed based on the results of a previous study. In the current study, four screwdrivers were evaluated on comfort (expected comfort at first sight and comfort after short time use...article 2005

Each seal has advantages and disadvantages. For shop assistants sealing bags could be a repetitive physically demanding action. Opening and closing the bags again can cause some discomfort or annoyance for consumers. Besides, it is an activity which can endanger safety, i.e., knives being used in opening...article 2005

(author), TNO Arbeid (author)To design comfortable hand tools, knowledge about comfort/discomfort in using hand tools is required. We investigated which factors determine comfort/discomfort in using hand tools according to users. Therefore, descriptors of comfort/discomfort in using hand tools were collected from literature and interviews. After that, the relatedness of a...article 2004

(author), TNO Voeding (author)Introduction: Limited quantitative information is available on dermal exposure to chemicals during various industrial activities. Therefore, within the scope of the EU-funded RISKOFDERM project, potential dermal exposure was measured during three different tasks: filling, loading and brushing.
