The main cause for the generation of airborne noise on the machines are the blowing nozzles.
The success of the applied noise reduction measures is assessed on the basis of the actual noise emission
values determined according to Annex A in relation to other machines of the same family.
4.8 Measures to prevent hazards due to cleaning
Bovine animals and equidae for which the traps are intended for are not food yet. In this case, hygiene
aspect only deals with cleaning requirements in the following subclauses.
Because the traps are soiled during use, they shall be cleaned according to information given in 7.1 b).
Cleanability shall be considered in the design and construction by assuming that the whole trap
represents a splash area (see Annex B).
Surfaces shall be designed and manufactured to prevent liquids from being retained (e.g. self-draining,
surface condition) so that the residual liquid can be removed by other means.
Chemical (detergent) and physical (high pressure water) risks are prevented according to the prevention
given in the instruction handbook (see 7.1 b)).
4.9 Measures regarding compliance with ergonomic principles
Unfavourable postures shall be avoided during the intended use of the machine and during maintenance,
cleaning, and other operations.
Suitably positioned lifting devices and/or transport carriages shall be provided for installation, removal
and transport of any part of the slaughtering traps weighing more than 25 kg.
If the mass of any part to be moved to fulfil the task exceeds 25 kg, a handling device shall be fitted.
If pushing and pulling is required, excessive effort shall be avoided.
5 Verification of safety requirements and/or protective/risk reduction
measures
This clause contains the verifications of compliance with the safety and health requirements of the
standard that shall be carried out in accordance with Table 1.
If partial dismantling proves necessary for certain tests, it shall not invalidate the result of the check.
Table 1 shows, for each identified parameter, whether the checks concern each box of the same series
(individual verification / I.V) or only one box (type verification / T.V), as well as whether it is a visual
inspection (V), by tests (T) or by measurement (M).
