Reasons for Applying Innovations for Scaffolding Work

Jong A. M., Molen H. v. d., Vink P., Eikhout S., Koningsveld E.

International Journal of Occupational Safety and Ergonomics

2003

Vol. 9, No. 2

161--175

In this paper reasons for applying and for not applying technical and organizational innovations in scaffolding work are studied. In a participatory ergonomic approach these innovations were developed to reduce problems concerning physical load of scaffolders. In this study reasons for the adoption of the innovations in the scaffolding sector are evaluated in 2 studies, in 48 companies. More than half of the scaffolding sector in the Netherlands adopted the innovations. Reasons for applying innovations concerned improvement of work and health and satisfaction with usage. The reason for not applying the innovations concerned specific situations, such as offshore work, in which innovations were not applicable.

Physical Effects of New Devices for Bricklayers

Vink P., Miedema M., Koningsveld E., Molen H. v. d.

International Journal of Occupational Safety and Ergonomics

2002

Vol. 8, No. 1

71--82

Bricklaying is a physically demanding job. Bricklayers frequently flex their trunk to pick up bricks and mortar and position these in a wall. The experienced workload is highest working with bricks at 0 to 50 cm from the floor. In this study the effects of 2 devices that have proven to be feasible in practice are evaluated. The 50 cm raise due to the 2 devices is experienced as comfortable, the estimated lumbar compression force was reduced, and observations indicate likewise. It is discussed that the field experiments have many drawbacks. Nevertheless, based on this study in combination with other literature the improvements could be recommended.
