Reduce noise exposure!!!

• S.C NUTRICOM S.A OLTENITA was found as a
  productive unit of concentraded forages in year
  1964. After 1990 is ghange into a company and in
  1995 became joind-stock company,today she have
  entirely joind-stock capital
• Because of massive capital investments mayde
  after she became joind-stock company,todaz she is
  a match more known name on the marchet of
  garden stuff.Concentreded forages factory is
  making food for animals from different farm, but
  also for personal farms were we breed pigs in
  Sohatu, Chirnogi, Manastirea,Dragalina and farms
  were we breed birds Dragalina, S.C. Avicola
  Calarasi.

Reduce noise exposure!!!

• Flow sheet unfolded to produce concentraded
  forages is
•     Purveyance and reception of raw materials
• Ø    Storage raw materials
• Ø    Weighing,measuring each component wich is
  used into job mix formula
• Ø    Grind macrodimensional components
• Ø    Mixing-for final product homogenization
• Ø    Graining forages with steam help
• Ø    Storaged final product(concentaded forages)
  warck or into a sack

Reduce noise exposure!!!

• Flow sheet is taking place with help from next
  devices
• Ø     Beltcarrier and elevating belt of raw
  materials
• Ø     3 electronic weighing equipaments and 2
  bonded strain gange
• Ø     2 automatica tare unit-bug for cereales
  and final product
• Ø     1 raw materials blender-4 t capacity
• Ø     2 mills to grind raw materials of 40t/h
  capacity
• Ø     3 graining machines -30t/h capacity
• Ø     3 coolers and 3 cruching mills
• Ø     tehnological water installations,vegetable
  oil, compressed air,steam
• Ø     control unit from were the flow sheet is
  supervised by a computer and automated.

Reduce noise exposure!!!

• Maximum design capacity of forages factory
  production is 40 t/h concentraded forages.
• Annual output was in 2004 of 67.000 tone
• Production tehnology was provided by a dutch
  company VAN AARESEN, and is being used sinse
  1997,with a contract which contain studies,
  production tehnology design and complet delivery
  of the line production,having all the equipament
  to the europen standars in that year.
• Those were certicated regarding tehnical quality,
  but also reguarding requirements of heath and
  safety at work.

6
Reduce noise exposure!!!

• Noise is a risk factor which can lead to hearing
  disabilitites and match more negative effects
• harm to internal ear
• increased risk of workplace accidents
• work related stress
• Going from this premises,the management of S.C
  NUTRICOM S.A OLTENITA and Work protection
  department allway thought that noise at workplace
  can not be neglected.
• Knowing the fact that machines used in the flow
  sheet generate noise ,S.C NUTRICOM S.A OLTENITA
  is allways taken action to reduce this risk
  factor.

7
Reduce noise exposure!!!

• Noise problem was approached into the next
  directions
• 1. Assessing the risks linked to
  noise,this thing is made with competent persons
  from Work protection department,under straight
  guidance of I.T.M Calarasi inspectors
• 2. Eliminate noise sources,there were this
  thing is possibile
• 3. Combating noise by adopting prevention
  policy and limited exposure
• 4. Reviewing and checking workplaces- to
  establish possible changes

8
Reduce noise exposure!!!

• Assessing the noise
• Is made by the peoples from Work Protection
  Department wich analyse workplaces exposed to
  noise ,noise sources,level,type and time exposure
  to noise of the employes.
• Also is taking into account informations given by
  the technical equipament producers and
  informations received from medical examination.

9
Reduce noise exposure!!!

• We found the workplaces wich are probable more
  expoused to noise as a professional insult
•   Graining machines workplace occupied by
  maitenance electrician and engine attendant which
  is taken care of the graining machines.Exposure
  to noise is permanently during the 12h shift
• Salt supply workplace occupied by an
  worker who supplyed with salt taking into
  account electrical measuring.Noise exposure is
  periodical,of approximated 6-7h/day during
  the 12h shift
•  Mills and Classification mills- flow sheet
  components were are not workplaces,but were
  noise is high and affect other workplaces from
  inside and outside

10
Reduce noise exposure!!!

• S.C NUTRICOM S.A OLTENITA allways maded
  measures to the level of noise with help from
  DSP Laboratory and under direct guidance of I.TM
  Calarasi inspectors.
• Last recordings was made in this year 2005 and
  this are the values
• Graining machines 99 dbA
• Salt supply 94 dbA
• Clasification mill 98 dbA
• Mills 104 dbA

11
Reduce noise exposure!!!

• Eliminate noise sources
• S.C NUTRICOM S.A OLTENITA is preocuped to
  eliminate noise sources, there were this is
  possible.
• Renewal found started with reversing line
  production in 1997 it meant not only adopting
  some modern solutions to made concentrateded
  forages,but also eliminate important noise
  sources, a lower consuming of energy,
  improvement work conditions.
• Also in 2002,the management of S.C NUTRICOM S.A
  OLTENITA takes a decision to interrupt tow
  cereale dryers US-14,from grain elevator,machines
  which contained important noise sources.

12
Reduce noise exposure!!!

• Combating noise
• 1. Combating noise at source though tehnical
  measures
• Avoiding impact metal on metal
• Regulary monitor and review machines and
  equipament
• Placing noise and vibration dampers(for example
  rubber bumper at mills)
• Cheking all machises with sound absorbent
  cabines

13
Reduce noise exposure!!!

• 2. Group measures to fight against noise
• Access restriction near noisy areas(for example
  workes access restriction near mills and graining
  machines,were are allowed only workes nominated
  on establish schedule
• Use for protection only materials soun
  absorbent, today in the building whith containd
  all the machines is put on panels type
  EcoPanel,type sandwich, having role to protect
  againt fire and sound isulation. This thing is
  made to reduce noise propagation outside and
  though other workplaces.
• Organised work program, so that work in noisy
  area can be limited
• Alternating workes at workplaces expouse to noise
• Planning all activitys which is making noise so
  that can affect a small number of worker.

14
Reduce noise exposure!!!

• 3. Individuals means of hearing protection
• People who works at places were noise is a risk
  factor most have individual hearing protectors
  internal and external(headset)
• Individual hearing protectors is necessary and
  obligatory
• Workes have possibility to choose the type of
  individual hearing protector much cozy and they
  are teached to use them

15
Reduce noise exposure!!!

• Workplaces reviewing submited to noise
• S.C NUTRICOM S.A OLTENITA is taking into account
  all workplaces submited to noise under straight
  guidance of I.T.M Calarasi inspectors.
• Periodical are made measures to the level of
  noise,and the last set of measures was made this
  year.
• For future our society it want to act against
  noise, to diminish this profesional insult,
  especialy that the european standard will be at
  a level of 87 dbA

16
Reduce noise exposure!!!

• Our measures to reduse noise in the future is
• Use only sound-proof housing near noise sources
• To build sound abrorbent cabines for our workers
  
• More individual hearing protectors but also for
  vibrations
• Program to hold under controll noise exposure
• To acquire only equipament that are protected
  against noise

17
Reduce noise exposure!!!

• Noise problem is more complex and from this
  point of view things are far from being good.
• S.C NUTRICOM S.A OLTENITA have not register until
  today any illness realted to noise and will be
  carrying on
• with the same attention to respect work
  legislation in
• long-term of european integration
• VA MULTUMESC !!!
