3.2 Description of machines
Combined machines
The machines covered by this standard are designed to prepare soft ice cream machinery (soft ice cream, frozen
yogurt and milk shake, whose main ingredients are generally milk and its derivatives. When the tub is in the load
position, the machine receives the ingredients are weighed or measured. This operation is controlled by the operator
of the machine.
The machine works the ingredients over a period of time defined by a user cycle.
At the end of the processing cycle, the product is downloaded into a mobile container through a regulator controlled
by the tap.
The machine can be operated manually or fully automatically.
In Figure 1 is shown a machine for ice cream expressed typical single tank with the following main elements:
— closure of storage liquid soft ice cream’s tank;
— storage liquid soft ice cream’s tank;
— feed opening device;
— mixing device;
— cylinder;
— dispenser;
— condensing unit;
— wheels or feet.

4 List of significant hazards
4.1 General
This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this
European Standard, identified by risk assessment as significant for this type of machinery and which require action
to eliminate or reduce the risk.
4.2 Mechanical hazards
The example shown in Figure 2 illustrates the position of danger zones associated with mechanical hazards for each
type of machinery:

11
---------------------- Page: 13 ----------------------
oSIST prEN 16876:2015
prEN 16876:2015 (E)
Zone 1: Access to trapping points between the storage liquid soft ice cream’s tank and the lid of the storage liquid
soft ice cream’s tank.
— crushing hazard of fingers and hands between the edge of the storage liquid soft ice cream’s tank and the lid.
Zone 2: Access to the rotating devices through the cylinder opening;
— hazards of trapping and shearing of arms between the blades of mixing device and the cylinder.
Zone 3: Access to the transmission mechanism of the mixing device;
— hazard of trapping and shearing of whole part of body.
Zone 4: Loss of stability of machine – access to areas adjacent to the machine;
— hazard of trapping and crushing of whole or part of body if machine overturns.
4.3 Electrical hazards
Hazard of electric shock from direct or indirect contact with live components.
Hazard of external influences on electrical equipment (e.g. cleaning with water).
If liquids such as spilled products or cleaning agents such as water come into contact with the electrical conductors,
there is a danger of electric shock.
4.4 Thermal hazards
High temperature of external parts and hand operated components creates a hazard of scalds and burns.
This hazard can be present also when the machinery is switched off.
4.5 Hazards generated by noise
Machinery can generate an airborne noise being able to involve a deterioration of hearing or to cause accidents due
to the interferences with the oral communication and the perception of the acoustical signals.
The noise can produce:
— ringing in the ears;
— tiredness, stress, etc.;
— other effects such as loss of balance, loss of perception;
— interference with speech communication;
— inability to hear acoustic warning signals.
4.6 Hazard generated by neglecting ergonomic principles
During operation, cleaning and maintenance, there could be the risk for safety and health resulting from awkward
body postures or from an excessive effort.
Movement or filling of the storage liquid soft ice cream’s tank especially at heights can create a risk of injury to the
body from lifting, pushing and pulling of heavy loads.

oSIST prEN 16876:2015
prEN 16876:2015 (E)
4.7 Hazard generated by neglecting hygienic design principles
The neglect of hygienic principles can create unacceptable contamination of foodstuff and therefore a risk to human
health of the operator and consumer, i.e. through physical, chemical or microbial pollution.
4.8 Hazards generated by loss of stability or tipping
Risk of impact or crushing of the body, in particular resulting from machinery with castors.
5 Safety and hygiene requirements and/or protective measures
5.1 General
Machinery shall be designed according to the principles of EN ISO 12100:2010 for hazards relevant but not
significant, which are not dealt with by this standard (e.g. sharp edges).
This specific risk assessment shall be part of the general risk assessment of the machine.
When fixed guards or parts of the machine acting as such, are not permanently fixed, e.g. by welding, their fixing
systems shall remain attached to the guards or to the machinery when the guards are removed.
5.2 Mechanical hazards
5.2.1 Elimination of hazards by design
Unless otherwise specified, interlocking guards shall be at least interlocking without guard blocking as defined in
EN ISO 14119:2013, 4.2, and they shall comply with EN ISO 14119:2013, Clause 5, 7 and 8.
Access to dangerous zones of drive shafts, coupling between the motor and the reduction gear shall be prevented
by fixed guards or movable interlocking guards in accordance with EN 953:1997+A1:2009.
Any gaps between moving parts and fixed parts of the machinery shall be so arranged that either it is not possible
for a finger to enter the gap (i.e. a gap of 6 mm or less), or the gap shall be sufficiently large to prevent trapping and
crushing in accordance with EN 349:1993+A1:2008, Table 1.
The safety-related parts of the control system shall meet at least a performance level “c” defined in accordance with
EN ISO 13849-1:2008. Openings in guards shall comply with EN ISO 13857:2008, Table 4.
5.2.2 Zone 1 – Access to trapping points between the reserve tank mixture and the reserve tank mixture
lid
Covers of the storage liquid soft ice cream’s tank shall be stable when they are in the open position to prevent
unintentional closing (e.g. with balancing systems). The speed of closure of lids of the storage liquid soft ice cream’s
tank shall not be greater than 50 mm/s when the distance from the tank to the front edge of the cover is less than
200 mm. For ergonomic requirements, see 5.6.
5.2.3 Zone 2 – Access to the rotating devices through the cylinder opening
Access to moving parts that contribute to the work, e.g. mixing devices, shall be prevented by fixed or movable
guards in accordance with EN 953:1997+A1:2009. Movable guards shall be designed with interlocking devices in
accordance with EN ISO 14119:2013. The opening of the interlocked guard shall stop any dangerous movements
within 4 s with the machine being empty.
Openings in guards shall be in accordance with EN ISO 13857:2008, Table 4.
Access to mixing device shall be prevented through the dispenser device, e.g. using a fixed or interlocked guard.
Guards shall prevent the access from any side of the machinery. The dimensions of the guard shall comply with the
13
---------------------- Page: 15 ----------------------
oSIST prEN 16876:2015
prEN 16876:2015 (E)
safety distances in EN ISO 13857:2008, Table 2. Guards shall fulfil the requirements given in
EN 953:1997+A1:2009. The guards shall be designed so that there is a good view of the area behind it, e.g. using
grids. Openings in guards shall be in accordance with EN ISO 13857:2008, Table 4.
It shall not be possible to operate the mixing element when the guards are opened, and the opening of a guard shall
stop the mixing element with 4 s when the machine is empty. If this is not possible, guards shall be interlocked with
guard locking which is released only when the mixing device is stopped.
5.2.4 Zone 3 – Access to the transmission mechanism of the mixing device
Access to the area in which the mixing device operates shall be prevented by an interlocked solid guard, movable
with lock control guard (see EN ISO 14119:2013, 4.3). Openings and/or loading slides in cover or in the tank shall be
in accordance with EN ISO 13857:2008, 4.5. For small openings shall be used to EN ISO 13857:2008, Table 4.
5.2.5 Zone 4 – Loss of stability of machine – access to areas adjacent to the machine
Machines shall be designed to be stable. For machines designed to be fixed to the floor, the instruction handbook
shall indicate the values of forces at the fixing points and the d
