Participatory Safety and Health Protection: Noise Impact Test Instrument
ABSTRACT
Forest harvesting is unquestionably hard work with high accident and health problem risk. The risk is generated not only due massive logs, uneven forest floor, wind blow, or uncertain weather, but also due to forestry work equipments used. Improper maintained chainsaw is widely recognized as the most common machines use for tree harvesting activity in most developing countries. Even though this kind of chainsaw generates noise and vibration that may badly influence health of chainsaw operator, most of the operator hesitated to wear earmuff or earplug in protecting their hearing. Previous research showed that the most reason of this misbehaves is attitude lacking of the operators. Therefore, a different approach in developing their working attitude through participatory safety and health protection is objective of this research. Worker‘s concentration measure instrument, designed in simple and easy to use with minimum bias potential, is proposed. Results shows that the instrument can prove that using earplug or earmuff would lessen the work concentration decrease due to noise generated by chainsaw. As this instrument can directly applied by anyone even those with low literacy ability or low educational background which is a common characteristic of forestry workers in most developing countries, this approach is believed as the most effective strategy as it would give a direct impact to the safety and health of the operators.
