5. RISK ANALYSIS AND HAZARDOUS SITUATIONS ACCORDING TO PED DIRECTIVE
N° Event Effect Risk
Actions to Eliminate the
Risk Information to minimise the
occurrence of a risk
1A
Violent Chocks,
Static or Dynamic
Loads applied
Appearance of
cracks, distor-
tions, possibility of
rupture
Leaks, liquid or gas
projections, Metal
parts projections. Only handling the units using
the chassis and lifting rings if
available. Handling procedure shown
in the IOM supplied with the
unit.
2A
Unit not installed
properly or
leveled to the
ground
Unusual stress in
the frame leading
to possible and
strains vibrations
and cracks
Leaks
Level the machine during
commissioning. In the case
where the unit is installed on
anti-vibration mountings, all
supporting points must be
used and the block hardness
must be selected according
to the type of units being
installed.
Indications on general
mechanical drawings in the
technical guide and the IOM
supplied with the unit.
3A
Unsuited hydrau-
lic or refrigeration
pipe- work
Unusual stress on
the pipe-work lead-
ing to possible and
strains vibrations
and cracks
Leaks
Proper support and fi tting of
the pipe-work on site.
Indications in the technical
IOM supplied with the unit.
4A
Outdoor tem-
perature below
freezing Strains, vibrations
and cracks, pipe
bursting.
Partial or complete
destruction of the
circuit, liquid/ gas
could be thrown out
of the unit
Provide anti-frost protection
(ei: Water treated with Glycol,
or trace heaters along the
pipe-work)
Indications in the technical
IOM supplied with the unit.
5A
Circuits exposed
to an unusual
heat source.
Modi fi cation of the
mechanical proper-
ties of certain ma-
terials with a risk
or rupture or pipe
bursting, leaks or
cracks appearing. Partial or complete
destruction of the
circuit, liquid/ gas
could be thrown out
of the unit
Recommended minimum and
maximum outdoor tempera-
ture– 20°C to 50°C during
operation.
Indications of the Min and
Max outdoor temperature on
the unit nameplate
–30°C to 50°C during storage
Do not expose any part of the
machine to a naked
fl ame
6A
Unusual increase
in the tempera-
ture of the Chilled
water return to
the evaporator
or the hot return
water to the
condenser
Increase of the
refrigerant pres-
sure in the heat
exchanger witha-
riskofexceeding the
working pressure
leading to possible
strains, vibrations,
cracks and pipe or
vessel bursting.
Partial or complete
destruction of the
circuit, liquid/gas/
metal parts could be
thrown out of the unit
Maximum chilled water return
temperature: 45°C
Indications in the technical
IOM supplied with the unit.
Maximum hot return water
temperature: 50°C
Install a temperature limita-
tion device
7A
Possibility of a
unit being hit by
lightning
Extreme heat, ex-
plosion, cracks.
Partial or complete
destruction of the
circuit, liquid/gas/
metal parts could be
thrown out of the unit
Provide an appropriate pro-
tection against lightning. Indications in the technical
IOM supplied
