This study deals with the safety of reindeer herding work. The possibi
lity of developing preventive measures and influencing the reindeer he
rders' behaviour by providing information were investigated. Since rei
ndeer herders in Finland work as private entrepreneurs (like farmers),
safety measures for them are voluntary; hence a great success rate wa
s not expected. The study population consisted of male herders age 16-
64 years (N=3324). The reindeer herding districts (N=53) were divided
randomly on a geographical basis into three groups: one group received
information about accident prevention in eight ''theme'' letters, ano
ther received it from occupational health personnel during medical exa
minations, while the third received general information from the press
. Data on accidents that had occurred were collected in two questionna
ires before and after distributing the information. As a result, a tot
al of 34 preventive measures were successfully developed for reindeer
herding work. The follow-up questionnaire showed that the herders had
implemented an average of 5.8 measures/respondent. The accident rate d
ecreased in two years from 20 to 15 accidents/1000 working days. Howev
er, there was no statistical difference between the groups that receiv
ed information from different sources. In conclusion it can be stated
that it is possible to develop preventive measures and to influence th
e safety behaviour in the reindeer herders' work by disseminating info
rmation. The press and journals would be most effective in the dissemi
nation in an occupation like this.
