Regional Basic Professional Training Course (BPTC) on Nuclear Safety
hydrocarbons. The former are found in fixed depots and are transported by road and rail.
The latter are stored and transported in the following physical forms:
5.4.2.3. Fire
Pressurized liquid at ambient temperature (propane);
Cryogenic liquid at ambient pressure (liquefied natural gas);
Pressurized gas at ambient temperature (acetylene);
Gas at ambient pressure (tanker degasing products).
A hydrocarbon leak may cause not an explosion, but a fire. Note that fires can also be
caused by aircraft crashing just after takeoff while carrying large quantities of fuel.
5.4.2.4. Dispersion of toxic gases
The presence of such products, likely to be released accidentally and suddenly, sometimes
in large quantities, is a hazard both to people and to equipment, both directly and
indirectly:
The toxic gases may get into the buildings through the ventilation network air
intakes and reach personnel directly, in particular those in the control room
operating the power station;
One example of a delayed action is corrosion, likely to cause operating failures of
systems, structures, or components.
It is therefore necessary to take stock of potential sources of toxic materials (chlorinated
substances, etc.) and corrosive substances (various acids, etc.) in the site's environment.
The maximum concentrations that might reach the site will be evaluated on the basis of
this survey, estimates of the maximum quantities of the substances likely to be discharged
