7 – HAZARDS ANALYSIS
Analysis of hazards that may occur during normal working, installation and maintenance. In line with what is required by
PED Directive 2014/68/UE, the manufacturer must follow the principles set out below in the following order to arrive at
the most appropriate solution:
a) eliminate or reduce hazards as far as is reasonably practicable
b) apply appropriate protection measures against hazards which cannot be eliminated
c) where appropriate, inform users of residual hazards
CAUSE
External environment – HEARTQUAKE (valid for ITALY only)
EFFECT
Deformation, structural settling
RISK
Breaking or deformation of pressure equipment, leakage of fluid.
SOLUTION
a) All the generators are equipped with suitable supports designed according
ASME
VIII Div.1 Ed. 2015,
for the following seismic zones : ZONE 1 – 2 – 3 – 4
on category A ground.
According to Ordinanza n° 3274 date 20.03.03 GAZZETTA UFFICIALE DELLA
REPUBBLICA ITALIANA
b) Make sure that the foundation ground is in “A” category, other type of grounds must be
certified as “A” category
Appliances weights are indicated on technical leaflets and on the constructive drawings.
The values can be also required at Servicing Department tel. +39 039 651762.
To avoid the separation of the foundation bolts, fix them to the ground with suitable
plinths. The rods must be fixed to the supports by washer, bolt and safety bolt or by anti-
screw washer.
Foundation rods diameters:
model 4-5… N° 4 rods M14 ( n° 2 on each support )
model 6-7-8-9… N° 4 rods M18 ( n° 2 on each support )
c) Make extremely sure whicht zone your city and the ground belong to. Some
discrepances about the parameters may cause structural settling and a general collapse
of the pipeworks with a dangerous appliance moving and falling or risk of leakage of fluid
(danger of burns).
CAUSE
External environment – WIND (valid for ITALY only)
EFFECT
Deformation, structural settling
RISK
Breaking or deformation of pressure equipment, leakage of fluid.
SOLUTION
All the generators are equipped with suitable supports designed
according ASME VIII
Div.1 Ed. 2015
with following parameters:
ZONE 1 – 2 - 3 – 4 – 5 – 6 – 7 - 8
CLASS A – B – C - D
CATEGORY I – II – III – IV – V
According to D.M.LL.PP. 16
th
January 1996 and Circ. LL.PP. 04
th
July 1996
a) To avoid the separation of the foundation bolts, fix them to the ground with suitable
plinths. The rods must be fixed to the supports by washer, bolt and safety bolt or by anti-
screw washer.
Our conformity declaration is referred to the support anchoration to the ground. Every
elevation of the appliance from the reference ground (ex: addition of supports or joists)
makes the declaration invalid.
Foundation rods riameters:
model 4-5… N° 4 rods M14 ( n° 2 on each support )
model 6-7-8-9… N° 4 rods M18 ( n° 2 on each support )
b) Make extemely sure that :
¾
Your country zone type
¾
Ground roughness class
¾
The consequent exposure class
Some discrepances about the parameters may cause structural settling and a
general collapse of the pipeworks with a dangerous appliance moving and falling or risk of
leakage of fluid (danger of burns).
