Noise Exposures and Hearing Protector Use at Small Logging Operations
2020
The study objective was to characterize noise exposures and hearing protector usage at small-scale logging operations. Noise dosimeters were used to measure exposures of 31 loggers at two cable operations and five mechanized operations in the United States. Activity cards were employed to evaluate hearing protector usage. Ninety-two percent of cable operation loggers were overexposed to noise according to National Institute for Occupational Safety and Health recommended criteria, but only 46% of cable loggers wore hearing protection. Six percent of mechanized operation loggers were overexposed to noise over the 8-h shifts observed, but this number increased to 33% when working 12-h shifts, which was a common practice among the participant companies. Only 6% of mechanized loggers wore hearing protection. Mean noise exposures and the proportion of hearing protection usage were both significantly greater at cable operations than at mechanized operations. None of the logging operations had hearing conservation programs in place. Despite the use of mechanized logging equipment and methods, the potential for noise-induced hearing loss remains a concern for workers employed at small-scale operations in the logging industry.
