Is on-board noise putting fish harvesters’ hearing at risk? A study of noise exposures in small-scale fisheries in Newfoundland and Labrador

Abstract

Prolonged exposure to high noise levels is a common but under-studied hazard in fishing that can cause occupational noise-induced hearing loss (NIHL). This paper presents risk assessment for hazardous noise exposures spanning across seven different fisheries and 12 small fishing vessels (24.4 m and under in length overall) in the Canadian province of Newfoundland and Labrador (NL). We documented noise exposure levels using personal dosimetry on fish harvesters and a job-based approach during regular fishing trips, and collected data on fishing vessels skippers awareness on noise hazards and on typical work patterns using respectively structured questionnaires and un-structured interviews. The study (a) documented high, often hazardous noise exposures, in most of the analyzed fisheries, (b) found that all the participants were partially or completely unaware of being exposed, and, (c) identified which activities on board are the most exposed.Drawing on our results we present a series of recommendations including: (a) the use of adequate hearing protection devices; (b) the development of effective design solutions to mitigate hazardous noise levels on existing and future vessels; and (c) the design and implementation of programs to enhance fish harvesters’ awareness of this important occupational hazard and how to prevent injury.
