The assumed efficacy of the ergonomic measures was based on evidence when possible, or
based on professional and ergonomic recommendations applied by
the Dutch Health and Safety Institute for the Construction Industry
when no scientific evidence was available.
The campaign was supported by an informative web site (www.
lichterwerkt.nl). The web site provided both workers and employers
with information about physical risks for each occupation,
MSDs resulting from those physical risks, and occupation-specific
ergonomic measures for reducing the physical exposure. The web
site included both written information and YouTube videos. Employers
were invited to use a freely available toolbox (with advice,
handy hints, and examples aimed at reducing the physical work
demands) and posters for their workplaces. The web site was
publicized through social media, radio, the Arbouw magazine, and
the Arbouw web site. The campaign lasted for 2 years, and in every
trimester another occupation received more specific attention.
