Technological Risk Prevention Plan — Grey Zone — Dunkirk Urban Community
Description
Plans for the prevention of technological risks (PPRT), created by the Law of 30 July
2003 following the AZF disaster in Toulouse, aim, by dealing with situations
inherited from the past, to improve and sustain the coexistence of the activity of the sites
industrialists called “high risk” with their neighbors. They are intended to ensure the
protection of people while offering industrial sites the opportunity to invest in their
future without questioning the security of their neighbourhood. They are an indispensable tool for
development of industrial zones in safe conditions.
The PPRTs provide, after a prior risk reduction at source (at the expense of the operator of the
industrial site):
“Bottom” measures on existing urbanisation, consisting of expropriations and rights
voluntary abandonment of property;
“Additional” risk reduction measures at source proposed by the operator
going beyond regulatory requirements, where implementation is less costly
whereas the land measures they help to avoid;
Restrictions or rules on future urban planning, on the use of future buildings, roadways
existing or future communication of equipment..., as well as restrictions on use or
building rules on future buildings built near the industrial site;
Work to be carried out on existing constructions in the vicinity of the industrial site, to
reduce vulnerability, work the amount of which may not exceed 10 % of the market value of the
all right.
** The different risk levels are staggered as follows:**
**TF+** Very Strong +
Effects whose consequences on human life are judged
very serious and whose cumulation of probability classes of occurrence of phenomena
dangerous at this level of intensity leading to these effects is
strictly
greater than D
.
**TF** Very Strong
Effects whose consequences on human life are judged
very serious
and
of which cumulation of probability classes of occurrence of phenomena
dangerous at this level of intensity leading to these effects is
between
D and 5E.
**F+** Fort +
Effects whose consequences on human life are judged
very serious
and
of which cumulation of probability classes of occurrence of phenomena
dangerous at this level of intensity leading to these effects is
strictly
less than 5E
Or
Effects whose consequences on human life are judged
serious
and of which
cumulation of probability classes of occurrence of dangerous phenomena
at this level of intensity leading to these effects is
strictly superior to D.
**F** Fort
Effects whose consequences on human life are judged
serious
and of which
cumulation of probability classes of occurrence of dangerous phenomena
at this level of intensity leading to these effects is
between D and
5E.
**M+** Medium +
Effects whose consequences on human life are judged
serious
and of which
cumulation of probability classes of occurrence of dangerous phenomena
at this level of intensity leading to these effects is
strictly less than 5E
Or
Effects whose consequences on human life are judged
significant
and
of which cumulation of probability classes of occurrence of phenomena
dangerous at this level of intensity leading to these effects is
strictly
greater than D.
M
Average
Effects whose consequences on human life are judged
significant
and
of which cumulation of probability classes of occurrence of phenomena
dangerous at this level of intensity leading to these effects is
between
D and
5E.
**FAI** Low
Effects whose consequences on human life are judged
significant
and
of which cumulation of probability classes of occurrence of phenomena
dangerous at this level of intensity leading to these effects is
strictly
less than 5E
Or
Potentially subject to an effect the consequences of which are broken
glass windows.
**The grey area**
Perimeters of industrial enclosures within which PPRT does not apply. These sectors are subject to specific risk prevention plans depending on the industrial processes present.
