6 Risk assessment and handling
6.1 Hazards
Pressure vessels according to this European Standard shall be designed, constructed, installed and
equipped under consideration of all significant hazards and risks that may arise when the vessel is
erected, tested and operated in accordance with the manufacturer’s instructions or else are reasonably
foreseeable.
Such hazards shall be analysed by the manufacturer prior to designing the vessel. Apart from normal
hazards connected to the operation of the vessel (see EN 13445-3:2014, 5.3), the following hazards
shall be considered (as applicable):
— corrosion and chemical attack;
— wear;
— external fire;
— reasonably foreseeable misuse of the vessel.
6.2 Hazard removal and risk reduction
6.2.1 General
As far as practically feasible, the vessel shall be designed as to remove or reduce the respective risk. If
removal of a certain hazard is not feasible, the vessel shall be designed and equipped to protect against
the respective risk or (as a final measure) information be given on the hazard and what measures are to
be taken to reduce the risks from the hazard. Such information shall be given through warning signs
and in the operating instructions.
NOTE The procedure to follow is outlined in Figure 6.2–1.
6.2.2 Design considerations
If it is envisaged that safety accessories will have to be fitted to the vessel, the vessel shall be equipped
with the necessary connections for such accessories.
NOTE The selection, application and installation of safety related accessories intended to protect pressure
vessels during operation are covered in EN 764-7:2002.
