Occupational Fatalities in the United States Commercial Fishing Industry, 2000–2009

ABSTRACT The occupational fatality rate among commercial fishermen decreased in the United States during 1992–2008; however, commercial fishing continues to be one of the most dangerous occupations in the United States, with an average annual fatality rate of 129 deaths per 100,000 fishermen in 2008. By contrast, the average annual occupational fatality rate among all US workers during the same period was four deaths per 100,000 workers. During the 1990s, numerous safety interventions were developed for Alaska fisheries that resulted in a significant decline in the states commercial fishing fatality rate. In 2007, the National Institute for Occupational Safety and Health (NIOSH) expanded surveillance of commercial fishing fatalities to the rest of the United States. The purpose of this report is to identify the hazards and risk factors for all causes of occupational mortality in the US commercial fishing industry, and to explore how those hazards and risk factors differ among fisheries and locations. During 2000–2009, 504 commercial fishing fatalities occurred in the United States. Most (261, 52%) occurred following a vessel disaster (defined as a sinking, capsizing, or other event in which the crew was forced to abandon ship) or a fall overboard (155, 31%). Fatalities occurred in Alaska (133, 26%), Northeast (124, 25%), Gulf of Mexico (116, 23%), West Coast (83, 16%), and the Mid- and South Atlantic (41, 8%) regions. Fatalities occurred most commonly while fishing for shellfish (226, 47%), groundfish (144, 30%) and pelagic fish (97, 20%). Average annual fatality rates were calculated for selected fisheries. The Northeast multispecies groundfish fleet had the highest average annual fatality rate (600 deaths per 100,000 full-time equivalent [FTE] fishermen) followed by the Atlantic scallop fleet (425 deaths per 100,000 FTE fishermen) and the West Coast Dungeness crab fleet (310 deaths per 100,000 FTE fishermen). To reduce fatalities among fishermen at greatest risk, additional prevention measures tailored to specific high-risk fisheries should be considered.

Worker satisfaction with personal flotation devices (PFDs) in the fishing industry: evaluations in actual use.

The purpose of this study was to determine which type of commercially available PFD resulted in the highest satisfaction among workers in the fishing industry. Fishing industry workers on four types of vessels wore and evaluated six different PFDs during their fishing seasons. Linear regression was used to test the differences in mean satisfaction scores, adjusting for clustered observations on vessels. The data were stratified by vessel type to determine the differences in PFD satisfaction within each vessel type. PFD D had the highest mean satisfaction score, but satisfaction with particular PFDs varied depending on the vessel type. Although the common objections by workers to wearing PFDs are that they are bulky and uncomfortable, some of the PFDs that were evaluated in this study received high scores for comfort and satisfaction. Given the availability of PFDs that are comfortable to wear while working, fishing vessel owners and operators should consider implementing policies mandating the use of PFDs on deck.

Drowning in Alaska: progress and persistent problems

Objectives. The purpose of this study is to evaluate and describe the current problem of drowning in Alaska, measure changes in the rates since earlier studies have been done and compare occupational and non-occupational drowning characteristics. Study design. This is a descriptive observational study, using existing records obtained from several sources to describe and compare drowning victims and event characteristics. Methods. Drowning fatality data were collected from death certificates, law-enforcement reports and news articles. Descriptive statistics and risk ratios were calculated to compare levels of risk based on incident and victim characteristics. Results. During 2000–2006, 402 unintentional drowning deaths, 108 of them occupational, occurred in Alaska, with an average annual fatality rate of 8.9 deaths per 100,000 Alaskans. The victim population was 86% male and 44% Alaska Native; 40% drowned in the south-west region of Alaska. For non-occupational cases with alcohol use documented, 33% were associated with alcohol consumption, as were 78% of those involved with all-terrain vehicle crashes. Only 17% of non-occupational victims who drowned while boating wore a Personal Flotation Device (PFD). Conclusions. The drowning rate in Alaska during 2000–2006 was 8.9 drowning deaths per 100,000 population. This shows a decrease from the rate reported in a 1996 study, but several problems persist. Males and Alaska Natives had elevated risks for drowning. A substantial portion of fatalities were associated with alcohol consumption. PFD use remains low, and child drowning rates were unchanged from earlier studies. Increased data on water temperature and immersion time may help demonstrate the benefits of PFD use to those at risk. Social marketing efforts should be adapted for at-risk populations.

Work-related traumatic injuries onboard freezer-trawlers and freezer-longliners operating in Alaskan waters during 2001–2012

BACKGROUND Workers onboard freezer-trawl (FT) and freezer-longline (FL) vessels in Alaska may be at high risk for fatal and non-fatal injuries. METHODS Traumatic occupational injuries onboard vessels in the FT and FL fleets were identified through two government data sources. RESULTS The annual risk of fatal injuries was 125 per 100,000 FTEs in the FT fleet, and 63 per 100,000 FTEs in the FL fleet. The annual risk of non-fatal injuries was 43 per 1,000 FTEs in the FT fleet and 35 per 1,000 FTEs in the FL fleet. The majority of injuries in the FT fleet occurred in the factories and freezer holds, whereas the most common injuries in the FL fleet occurred on deck while working the fishing gear. CONCLUSIONS The findings confirmed that workers in those fleets were at high risk for work-related injuries. Injury prevention should focus on removing hazards in the work processes injuring the most workers.

Occupational fatalities in Alaska: two decades of progress, 1990-1999 and 2000-2009.

INTRODUCTION Alaska had the highest work-related fatality rate of any state during 1980-1989. The National Institute for Occupational Safety and Health established the Alaska Field Station (AFS) to address this problem. METHODS AFS established surveillance systems to provide scientific assessments of occupational hazards. Interventions were developed in collaboration with partners and evaluated. RESULTS During 2000-2009, Alaska experienced a 42.5% decline in work-related fatalities over the previous decade of 1990-1999. In 2009, the workplace fatality rate for Alaska was 5.6/100,000 workers. Commercial pilot deaths were reduced by 50% and Bering Sea crab fishing death rates were reduced by 60%. Building on this success, AFS established national programs to improve safety in the commercial fishing and oil and gas extraction industries. IMPACT ON INDUSTRY A focused, epidemiological approach to reducing fatalities in high-risk occupations is effective. Ongoing commitment to this type of approach will assist in continued success in Alaska and elsewhere.

Utility of a Work Process Classification System for characterizing non-fatal injuries in the Alaskan commercial fishing industry

Background The US commercial fishing industry is hazardous, as measured by mortality data. However, research on non-fatal injuries is limited. Non-fatal injuries constitute the majority of occupational injuries and can result in workers’ lowered productivity and wages, lost quality of life, and disability. In the United States, a Work Process Classification System (WPCS) has previously been applied in Alaskan freezer-trawl and freezer-longline fleets to identify causes of injuries and specific hazards, but not to other fishing fleets. Objectives This descriptive epidemiologic study aimed to explore the application and modification of the WPCS in multiple Alaskan fleets, characterize non-fatal occupational injuries in these fleets, and identify work processes that could be targeted for further investigation and future injury prevention efforts. Design Traumatic, non-fatal injuries on-board Alaskan commercial fishing vessels were identified through United States Coast Guard investigative reports. Characteristics of injuries, as well as worker characteristics, were analysed. Injuries were coded using the WPCS. Results We successfully utilized the WPCS to code non-fatal injury cases (n = 136). The most frequent main work processes associated with non-fatal injuries included: on-board trawlers, handling frozen fish and processing the catch; on-board vessels using pot/trap gear, handling the gear and shooting/setting the gear; on-board longliners, traffic on board and hauling the gear; and on-board processor vessels, processing the catch, other work with the catch, and handling frozen fish. Conclusions The study confirmed that a WPCS can be applied to multiple Alaskan fleets to identify hazardous tasks. Hazards were unique for each vessel gear type. Future injury prevention efforts should target work processes associated with the most frequent and most severe injuries. Future studies should establish time estimates for work processes in order to determine risk estimates. Efforts to improve non-fatal injury reporting, especially on smaller commercial fishing vessels, should be undertaken.Background The US commercial fishing industry is hazardous, as measured by mortality data.

Reported traumatic injuries among West Coast Dungeness crab fishermen, 2002-2014.

BACKGROUND Commercial fishing is a high-risk occupation. The West Coast Dungeness crab fishery has a high fatality rate; however, nonfatal injuries have not been previously studied. The purpose of this report was to describe the characteristics of fatal and nonfatal traumatic occupational injuries and associated hazards in this fleet during 2002-2014. MATERIALS AND METHODS Data on fatal injuries were obtained from a surveillance system managed by the National Institute for Occupational Safety and Health. Data on nonfatal injuries were manually abstracted from Coast Guard investigation reports and entered into a study database. Descriptive statistics were used to characterise demographics, injury characteristics, and work processes performed. RESULTS Twenty-eight fatal and 45 nonfatal injuries were reported between 2002 and 2014 in the Dungeness crab fleet. Most fatalities were due to vessel disasters, and many nonfatal injuries occurred on-deck when fishermen were working with gear, particularly when hauling the gear (47%). The most frequently reported injuries affected the upper extremities (48%), and fractures were the most commonly reported injury type (40%). The overall fatality rate during this time period was 209 per 100,000 full-time equivalent workers and the rate of nonfatal injury was 3.4 per 1,000 full-time equivalent workers. CONCLUSIONS Dungeness crab fishermen are at relatively high risk for fatal injuries. Nonfatal injuries were limited to reported information, which hampers efforts to accurately estimate nonfatal injury risk and understand fishing hazards. Further research is needed to identify work tasks and other hazards that cause nonfatal injuries in this fleet. Engaging fishermen directly may help develop approaches for injury prevention.

Preventing fatal winch entanglements in the US southern shrimp fleet: A research to practice approach

INTRODUCTION During 2000-2011, 35 injuries (8 fatal) involving winches were reported to the Coast Guard in the Southern shrimp fleet. Injuries involving the main winch drums had a higher risk for fatal outcomes compared to injuries involving the winch cathead (RR=7.5; 1.1-53.7). The objective of this study was to design effective solutions to protect deckhands from entanglement hazards posed by winches found on the vessels in the Southern shrimp fleet. METHODS Based on injury characteristics, site visit observations, and input from vessel owners, NIOSH determined that the design and implementation of effective main-winch guarding was a feasible first-step in mitigating the entanglement hazard. Design considerations for stationary guards favor systems that are simple, affordable, durable, unobtrusive, and will not interfere with normal fishing operations. In addition, an auxiliary-stop method was tested to prevent entanglements in try-net winches. RESULTS Standardized passive guards were designed for three commonly found main winch models. Initial prototype guards have been sea-tested. The design of six additional guards is underway, for a total of three iterations for each winch model identified. These will incorporate features found to be valued by fishermen, will be more efficient, and will reduce the overall cost of fabrication and maintenance. Sea testing of these iterations continues. The auxiliary-stop circuit control prototype system was designed to prevent entanglements in the try-net winch and is currently being sea tested. DISCUSSION NIOSH has completed initial designs for stationary-winch guards. Through collaborations with shrimper associations and safety groups, the successfully tested winch guard and auxiliary stop designs will be made available to qualified welders and craftsmen to use. This approach has proven effective in preventing other types of winch injuries. PRACTICAL APPLICATIONS Injury epidemiologic methods and industry input are an effective way to identify workplace hazards and to design effective safety interventions to control hazards.

Work-related injuries in the Alaska logging industry, 1991-2014

BACKGROUND Although loggers in Alaska are at high risk for occupational injury, no comprehensive review of such injuries has been performed since the mid-1990s. We investigated work-related injuries in the Alaska logging industry during 1991-2014. METHODS Using data from the Alaska Trauma Registry and the Alaska Occupational Injury Surveillance System, we described fatal and nonfatal injuries by factors including worker sex and age, timing and geographic location of injuries, and four injury characteristics. Annual injury rates and associated 5-year simple moving averages were calculated. RESULTS We identified an increase in the 5-year simple moving averages of fatal injury rates beginning around 2005. While injury characteristics were largely consistent between the first 14 and most recent 10 years of the investigation, the size of logging companies declined significantly between these periods. CONCLUSIONS Factors associated with declines in the size of Alaska logging companies might have contributed to the observed increase in fatal injury rates.

Factors associated with crewmember survival of cold water immersion due to commercial fishing vessel sinkings in Alaska

Occupational fatality surveillance has identified that fishing vessel disasters, such as sinkings and capsizings, continue to contribute to the most deaths among crewmembers in the US fishing industry. When a fishing vessel sinks at sea, crewmembers are at risk of immersion in water and subsequent drowning. This study examined survival factors for crewmembers following cold water immersion after the sinking of decked commercial fishing vessels in Alaskan waters during 2000-2014. Two immersion scenarios were considered separately: immersion for any length of time, and long-term immersion defined as immersion lasting over 30 minutes. Logistic regression was used to predict the odds of crewmember survival. Of the 617 crewmembers onboard 187 fishing vessels that sank in Alaska during 2000-2014, 557 (90.3%) survived and 60 died. For crewmembers immersed for any length of time, the significant adjusted predictors of survival were: entering a life-raft, sinking within three miles of shore, the sinking not being weather-related, and working as a deckhand. For crewmembers immersed for over 30 minutes, the significant adjusted predictors of survival were: wearing an immersion suit, entering a life-raft, working as a deckhand, and the sinking not being weather-related. The results of this analysis demonstrate that in situations where cold water immersion becomes inevitable, having access to well-maintained, serviceable lifesaving equipment and the knowledge and skills to use it properly are critical.
