MEPs debated a report on preventing accidents involving dangerous substances during the plenary session in the European Parliament on 13 June 2012.
The Environment Committee voted in October last year in favour of updating accident prevention rules for dangerous substance sites.
The committee's recommendation called for updates to the Seveso Directive rules - first introduced in the 1970s after an accident in the Italian town, Seveso.
MEPs voted for improved chemical classifications, clearer information for the public and more frequent inspection of sites.
They say inspections should be made at least every three years, and at least once a year for higher-risk sites.
Whilst some Seveso sites already meet these rules under the Industrial Emissions Directive, this means that others will be inspected more often in future.
MEPs have called on the Commission to examine whether the scope of the Seveso Directive should be extended to include offshore oil exploration, pipelines and certain nanomaterials.
