  1. NHCA 2010 HEARING LOSS PREVENTION TRAINING, NOISE MEASUREMENTS AND AUDIOLOGICAL EXAMS IMPROVES WORK CONDITIONS AMONG INDUSTRIAL FISHERMEN IN THE SOUTH OF BRAZIL Evelyn Albizu Fundacentro/Ministryof Labor Curitiba, Paraná, Brazil

  2. NHCA 2010 This presentation reports: partial findings from AquaForum, a Brazilian Government National Program which included hearing loss prevention training and education,noise measurements andaudiological testing and how it contributed to change occupational health practice among fishermen in Brazil.

  3. INTRODUCTION Fishing is: one of the humankind oldest productive activities; one of the most important global economical sectors (1% of global workforce); one of the most dangerous working activities; responsible for 75% of the all global mortality among workers; ~15 million fishermen are employed aboard fishing vessels operating in the marine capture fisheries, mostly on vessels less than 24 meters in length. SOURCE: ILO 2009

  4. COMMERCIAL FISHING: Vessels > than24 meters in length: Industrial Fishing Vessels < than 24 meters in length: Small-scale and Artisanal fishing Small-scale - use most advanced fishing technology and electronics on board, small fishing craft (high level of income and standard of living) Artisanal fishing -mostly poor fisherfolk, operate low-investment boats and fishing equipment. Most live in remote, coastal communities where living standards and quality of life keep them at the bottom of the socio-economic pyramid (developing countries) Source: ILO 2009

  5. BRAZIL artisanal fishermen (work > than 8 hours/ day, with less than 16 hours of rest and often > than 5 days/week, but they go home everyday): ~ 1.2 million (family based economic regime and small vessels); industrial fishermen work embarked from 20-30 days/trip, exposed to motorboats noise, hardly any acoustical rest due (1 hour sleep – 4 hours work): 45,000(employees of industrial fishing companies). Source: SEAP/PR, 2009

  6. METHODS Participants were interviewed on medical and work history, type of vessel used, occupational and non-occupational noise exposure. Noise measurements were conducted during representative fishing trips. Audiological tests were conducted after acoustical rest (14 hours). Lectures were given to the fishermen showing them the results (Training and Education).

  7. Sound Level Measurements Equipments used: • Integrating Sound Level Meter • Noise Dosimeters The standard used is based on TWA of 8 hours, 40 hours/week and a PEL of 85 dB (A) for 8 hours of exposure, with both 3 dB and 5 dB exchange rates.

  8. Sound level measurements

  9. Audiological Testing Pure-tone audiometry (air- 500 Hz- 8 kHz range- and bone conduction) & immitance audiometry ARTISANAL FISHERMEN

  10. Audiological Testing INDUSTRIAL FISHERMEN

  11. RESULTS Fishermen, artisanal and industrial are exposed to high sound levels – 85 to 114 dB(A) - from motorboats In both categories: The working conditions expose them to other unfavorable work factors such as climatic variations, humidity, vibration, sleep deprivation and night work.

  12. 2004: NUMBER AND % OF THE AUDIOMETRIC CLASSIFICATIONS OF THE STUDIED GROUPS 141 male artisanal fishermen GROUP 1: Exposed to high SPL / motorboats, no previous noise exposure; GROUP 2: Exposed to high SPL / motorboats, with previous noise exposure; GROUP 3: Not exposed / boats without engines, no previous noise exposure; GROUP 4: boats without engines and previous noise exposure. Paini, Morata, Corteletti, Albizu et al., 2009

  13. RESULTSIndustrial Fishermen

  14. TRAINING & EDUCATION Hearing Loss Prevention Artisanal fishermen (Paraná): 402 participants (2007 & 2008) Industrial fishermen (Santa Catarina): 193 participants (2008 & 2009)

  15. LEGISLATIONC188 Work in Fishing Convention, 2007(revision of Convention 113- Medical Examination, 1959) Article 11: Each Member shall adopt laws, regulations or other measures providing for: (a) the nature of medical examinations; (b) the form and content of medical certificates; Article 12:Ona fishing vessel of 24 meters in length and over, or on a vessel which normally remains at sea for more than three days: 1. The medical certificate of a fisher shall state, at a minimum, that: (a) the hearing and sight of the fisher concerned are satisfactory for the fisher's duties on the vessel;

  16. IN BRAZIL In 2009, due to our findings the Port Authority in Itajaí, a coastal city in Santa Catarina State, began requiring audiometric testing prior to issuing or renewing a fishing license.
