Risk assessment due to transmission of vibrations from olive electrical and pneumatic harvesters to the Hand-Arm System (HAV): definition and evaluation of levels and exposure time
The paper is focused on exposure to vibration during the olive harvest for farmers of Azienda
Agraria of Università Politecnica of Marche to highlight the importance of the exposure to
vibrations transmitted to the hand-arm system in agriculture and its consequences on human
health. To assess the exposure to mechanical vibration transmitted to operators during the olive
harvest, measurements were done using a vibration measuring equipment during the regular
working activity. The vibration samplings were carried out on electric and pneumatic
harvesters. The measured data were compared with the prevention values for the safety
requirements fixed by the normative. The analysis of the results shows that the electric
harvesters transmit vibrations equivalent and in some cases higher than ones provided by the
pneumatic harvesters. The paper, evaluating the risk to the hand-arm system due to vibrations,
give an overview of the exposure of workers to the risks arising from vibrations to which
operators are exposed when using olive harvesters
Risk due to noise during the olive harvest: the electrical and pneumatic harvesters
The review of trends in farm practices and machinery development suggests that noise problems are still prevalent in agricultural situations. The aim of this study is to assess the noise exposure
for workers during olive harvest in Azienda Agraria Didattico-Sperimentale of Università Politecnica delle Marche. A monitoring of noise levels is conducted in some days of the years 2010-2011.
Noise samplings were carried out on electric and pneumatic harvesters. For sound pressure levels measurements an integrating-averaging sound-level meter, B&K2250 type, was used and
the measurement procedure was set up in accordance with ISO 9612:2011. The tests have been carried out during the regular working activity with all the shakers operated by the same
worker expert in the use of this machines. The results allowed to evaluate noise exposure during the olive harvest. Every machine has been analyzed to establish the level of noise produced according to the laws in force. With the collected data it was possible to establish noise exposure for every instrument. The measured sound pressure levels (Lp,A,eq,T) for all the harvesters under test are included between 70,2 db(A) and 83,5 dB(A). Noise pressure levels are higher for pneumatic type harvesters compare to electric type harvesters. The highest C-weighted peak sound pressure level (Lp,Cpeak) measured is
equal to 109,8 dB(C), widely below the limits value. The daily noise exposure level determined
respects the limitations in D.Lgs.81/2008 on the minimum health and safety requirements
regarding the exposure of workers to the risks arising from physical agents (noise)
