— 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.
