General information and safety regulations
3.5.1 Clothing
Those working or carrying out maintenance on the
machine/partly completed machinery must always wear
clothing that is adequate for the type of operation to be
carried out. Furthermore, it must comply with the safety
requirements of the legislation in force in the country of
use of the machine/partly completed machinery itself.
In general, the operator must wear the correct PPE. The
operator must wear safety footwear with non-slip soles;
moccasins, clogs, slippers or other types of footwear
that can compromise the mobility of the person is not
allowed. Hair must be tucked under a special cap.
Clothing worn must be adequate for the work to be carri-
ed out, in particular avoid wearing:
•
Loose-fitting clothes
•
Wide sleeves
•
Ties and scarves
•
Necklaces, bracelets and rings
Both your clothes and hair could get caught in rotating
parts and result in serious consequences.
3.5.2 Access to the work area
The work area (in particular the areas where the control
panels and emergency pushbuttons are installed) must
never be occupied by material or anything else, so that
nothing interferes with the operator's freedom of move-
ment. In the event of an emergency, personnel in charge
must have immediate access to the BLAST CHILLER. It
is advisable to prohibit access to the work area to
persons not trained to use the blast chiller by using
appropriate warning signs.
The use of the BLAST CHILLER is prohibited to
children and all unsuitable persons; these persons
must therefore be kept at a safe distance from it.
During maintenance operations, especially when
operating with guards open or safety devices
disconnected, which is permitted only to personnel
formally authorised and duly instructed, great care
must be taken to ensure that THE WORK AREA IS
INACCESSIBLE TO PERSONS not directly involved
in these operations.
During maintenance operations, the area where this
operation is carried out must always be clean and
dry.
If it is necessary to carry out work near electrical
components, always work with dry hands and wear
electrical insulating gloves.
At the end of maintenance operations, check that
no tools used have been left inside the BLAST
CHILLER and that any guards removed have been
repositioned.
3.5.3 Environmental usage conditions
1) TEMPERATURE AND HUMIDITY
The BLAST CHILLER must be used in rooms with an
ambient temperature b 5°C and + 32°C and
with relative humidity below 55%.Exceeding this limit
does not affect machine functionality. In the case of a
blast chiller with a remote condensing unit (i.e. positio-
ned outside) outside air temperatures must NOT exceed
43°C.
2) OPERATING ENVIRONMENT
The BLAST CHILLER must be used in locations
protected from atmospheric agents (rain, hail, snow, fog,
etc.) and only in industrial/workshop environments. In
the case of a remote condensing unit, this must be
installed in a special machine room or if positioned
outside it must be protected from atmospheric agents
(rain, hail, snow, fog, etc.) and in a place sheltered from
the sun. In any case, minimum levels of ventilation must
be guaranteed. The BLAST CHILLER is not designed to
be used in an explosive or partially explosive atmosphe-
re: it is therefore forbidden for the user to use it in such
conditions.
3) LIGHTING
The place where the BLAST CHILLER is installed must
have a lighting system that makes it easy to identify the
pushbuttons and the emergency stop and control
devices. An indicative value of good industrial lighting
for acceptable accurate working is 300-600 lux).
4) ATMOSPHERES AND AGGRESSIVE
SUBSTANCES WITHIN THE CABINET
The freezing, cooling and tenderising of some food
products generates the release of particularly aggressi-
ve and corrosive vapours for the evaporator coil. Despite
being protected by surface treatment, caution must be
exercised with some products. In particular, the surface
treatment adopted for evaporator coils of trolley-type
blast chillers is not suitable in the presence of:
