Risk communication and public participation are considered in the context o
f the forthcoming requirements of the 'Seveso II' Directive. The discussion
draws substantially on the findings of a research project which has invest
igated public perceptions of the risks from major accident hazards in seven
communities in the UK. implications for the Directive's requirements on em
ergency information provision, public access to safety reports and consulta
tion on emergency plans are considered. Our conclusions stress the need for
risk communication to be seen as a long term and ongoing process, involvin
g active listening to public reasoning about risk and a sensitivity to the
context in which communication is taking place, in meeting both needs and r
ights to information and encouraging and enabling public participation, we
conclude that the Directive should contribute in some degree to an improved
environment for dialogue and the building of trust. (C) 1999 Elsevier Scie
