This study examined the architecture of the relationships between component
s of organizational safety climate, including employee attitudes to safety
issues and perceptions of the work environment, and related this to self-re
ported levels of safety activity. Data were collected from a large multinat
ional manufacturing organization by questionnaire. A total of 915 valid que
stionnaires were returned and formed the basis for structural equation mode
lling and subsequent analyses. These data showed that a common structure, o
r architecture, of attitudes to safety issues and perceptions of the work e
nvironment could be constructed that explained levels of safety activity. T
he strength of employees' attitudes with regard to safety management played
a pivotal role in this model through both direct and indirect paths. This
is consistent with earlier findings on the importance of management commitm
ent in organizations with well developed safety cultures. An examination of
the differences between plants/sites showed that employees differed in the
ir attitudes to safety issues, such as the management of safety and communi
cation, and in their perceptions of workplace hazards. It is intended that
this model be further utilized within the organization under study as a bas
is for monitoring safety performance and planned improvements in safety.
