Material working conditions<br />

research on material working conditions has largely fol<strong>low</strong>ed two<br />

approaches. clinically-oriented studies have often investigated very<br />

specific types of working conditions in specific occupations. in those<br />

studies, social inequalities often remain unaddressed. social<br />

epidemiological studies mostly rely on broad, self-reported material<br />

working conditions. in the overview be<strong>low</strong>, essentially the latter<br />

approach is fol<strong>low</strong>ed. Material working conditions are discussed in<br />

different groups: load-related hazards, vibrations, noise, extreme<br />

temperatures, dangerous situations, ergonomic risk factors and<br />

toxic exposures.<br />

load-related risks are the result of mechanical shocks, forceful<br />

gripping of tools and machines, external loads related to the use of<br />

force and the impact of hard or sharp edges (Muggleton, allen, &<br />

chappell, 1999). important risk groups include various kinds of<br />

industrial workers (hansson & Jensen, 2004), maintenance<br />

personnel (Kumar & Kumar, 2008), construction workers<br />

(hildebrandt, Bongers', dul, Van dijk, & Kemper, 2000) and health<br />
