Injury Prevention Practices as Depicted in G- and PG-Rated Movies, 2008-2012.

Unintentional injuries are the leading cause of death among children in the United States. The use of recommended safety practices can reduce injuries. Children often learn behaviors from media exposure. Children's movies released in 1995-2007 infrequently depicted appropriate injury prevention practices. The aim of this study was to determine if injury prevention practices in children's movies have improved. The top grossing 25 G- and PG-rated movies in the United States per year for 2008-2012 were eligible for inclusion in the study. Movies or scenes were excluded if they were animated, not set in the present day, fantasy, documentary, or not in English. Injury prevention practices involving riding in a motor vehicle, walking, boating, bicycling, and four other activities were recorded for characters with speaking roles. Fifty-six (45%) of the 125 movies met the inclusion criteria. A total of 603 person-scenes were examined involving 175 (29%) children and 428 (71%) adults. Thirty-eight person-scenes involved crashes or falls, resulting in four injuries and no deaths. Overall, 59% (353/603) of person-scenes showed appropriate injury prevention practices. This included 313 (70%) of 445 motor-vehicle passengers who were belted; 15 (30%) of 50 pedestrians who used a crosswalk, 2 (7%) of 30 boaters who wore personal flotation devices, and 8 (29%) of 28 bicyclists who wore helmets. In comparison with previous studies, there were significant increases in usage of seat belts, crosswalks, personal flotation devices, and bicycle helmets. However, 41% of person-scenes still showed unsafe practices and the consequences of those behaviors were infrequently depicted.

Fatalities in recreational boating and sub-aqua diving

To establish the causes and circumstances of fatalities in recreational boating and sub-aqua diving inland or around the United Kingdom during the years 2006 and 2007, to comparefatal accident rates according to the type of boat, to identify causal patterns, and to discuss preventative measures to reduce the fatalities. Examinations of marine accident files and reports from the Marine Accident Investigation Branch and other sources, including the Royal National Lifeboat Institution, Maritime and Coastguard Agency, Association of Inland Navigation Authorities and the British Sub-Aqua Diving Club. There were 102 fatalities in recreational boating and 28 in sub-aqua diving with corresponding fatal accident rates of 12.0 and 48.0 per million participants. In recreational boating, fatal accident rates were highest for motor and power boats (20.2), yachts (19.3) and canal boats (16.0). Most fatalities (64%) occurred from April to September, with a peak during August. In recreational boating, 24% of fatalities were recorded as alcohol-related. These were most prevalent in canal boats, occurring largely during the autumn and winter months rather than during summer holidays, among people living on boats, often asa result of fires and falls overboard. Causal patterns of the fatalities varied strongly according to the type of recreational boat anddiving. Prevention of fatalities should include raising awareness of hazards, adequate training in diving, yachting and canoeing, etc., installation and maintenance of smoke alarms and fire extinguishers on residential boats, and increases in the use of personal flotation devices in recreational boating.

Escape from a Submersible Vehicle Simulator Wearing Different Thermoprotective Flotation Clothing

Winter road workers, who drive heavy vehicles on ice-covered waterways, are at risk for ice failure and subsequent drowning in frigid water. Some workers who are recommended to wear thermoprotective flotation clothing are concerned that buoyancy or bulk may impede underwater exit. Using a simulator, 10 volunteers (2 women) compared everyday winter clothing (Control), a flotation Jacket and Overall, and an inflated inflatable personal flotation device (Inflated Vest). On each study day, all clothing conditions were tested in either Cool (20 degrees C) or Cold (8 degrees C) water conditions using a randomized balance design. After each trial, subjective ratings for thermal sensation and exit tasks along with exit task times were determined. Exit task times were unaffected by clothing or water conditions. Compared to Control, the Inflated Vest was rated with higher exit task difficulty and impedance, while the Jacket and Overall were not (ratings for exit task difficulty and impedance in cold water were: Control, 'a little' and 'none'; Jacket, 'a little' and 'a little'; Overall, 'a little' and 'moderate'; and Inflated Vest, 'moderate' and 'moderate - a lot'). Finally, there was a training effect, with total exit times improving by 20% from trials 1-8 (12.3 to 9.8 s). Results suggest that, compared to Control clothing, flotation Jackets and Overalls do not increase exit time or impede exit during egress from a submerged vehicle while providing thermoprotection and buoyancy in 20 degrees C and 8 degrees C water. The Inflated Vest created the most perceived exit impedance in comparison to Control.

Adaptation to Aquatic Risks due to Climate Change in Pangnirtung, Nunavut

We use a vulnerability framework to examine how residents of Pangnirtung, Nunavut, perceive the risks of aquatic activities in the context of adaptation to a changing climate. Our findings suggest that community members identify climate change as increasing the risk of many aquatic activities and have adapted some practices accordingly. However, further adaptation to these changing risks is impeded by three main barriers: (1) financial constraints, (2) Inuit resistance to adopting what some consider Euro-Canadian water safety practices, and (3) issues with the design of flotation devices. Participants suggested the following practical changes: (1) make personal flotation devices, lifejackets, and floater suits available to all residents at local stores at a subsidized rate, or provide them free of charge through the community; (2) create water safety promotional items that feature locally developed messages in both Inuktitut and English; (3) include traditional knowledge in water safety campaigns; and (4) use the local pool to train residents in water safety. These changes would not only help residents adapt to changing risks, but also help incorporate climate considerations into policies and programs.

Case analyses of all children’s drowning deaths occurring in Sweden 1998–2007

The goal of this research project was to explore circumstances surrounding each drowning death occurring to children and adolescents ages 0-17 in Sweden during the years 1998-2007. Records from the National Board of Forensic Medicine (NBFM) and other sources were analysed. We collected information on children's personal characteristics (sex, age, ethnic background, weight, height, physical condition, and pre-existing health conditions) and the circumstances of deaths (time and place of occurrence, type of drowning, resuscitation efforts and medical care given, for example). We also collected information on prevention factors: the physical environment, adult supervision, whether or not the child could swim, and if the child was using a personal flotation device at the time of death. Our analysis showed that 109 children had drowned in Sweden during the study period - of this group, 96 had died from unintentional causes. Children from immigrant backgrounds, particularly with families coming from the Middle East and Iran, were inordinately represented in the group of victims who had died from unintentional drowning deaths. Other risk factors included: coming from a single parent-headed family, alcohol use by older victims and a lack of ability to swim. Prevention efforts to prevent drowning in the future should focus on preventing alcohol use by young bathers; better fencing around swimming sites; improved coverage of swimming lessons to all children in Sweden, especially children from immigrant families; more education on drowning risks for single parents; and better awareness by adults on the need for constant supervision of children and adolescents in and near water.

Compliance with an ordinance requiring the use of personal flotation devices by children in public waterways.

Introduction:For children ages 1–14, 21.6% of drowning cases involve swimming, wading, or playing in natural bodies of water, such as rivers and lakes. Personal flotation devices (PFDs) are believed to be an effective prevention measure. We measure compliance with city and county ordinances, publicized but not actively enforced, requiring that PFDs be worn by children accessing public bodies of water in Sacramento County, California.Methods:During June–August 2010, volunteers conducted 79 observation sessions at three popular local river beaches where PFDs were available for use at no cost. They recorded personal characteristics and PFD use for 1,727 children in or very near the water and believed to be 0–13 years of age (the age covered by the ordinances). We used logistic regression to quantify differences in use by subject characteristics and study site.Results:The prevalence of PFD use was 29.9% overall, with large and significant differences by age: < 1, 55.6%; 1–4, 37.6%; 5–10, 29.4%; 10–13, 14.6%; P < 0.0001. Usage did not vary significantly by sex or race/ethnicity, and was somewhat higher at one study site (33.1%) than at the others (25.9% and 27.3%), P = 0.009.Conclusion:The combination of a statutory requirement and a cost-elimination strategy was associated with moderate rates of PFD use that were highest among young children.

Predictors of personal flotation device (PFD) use among workers in the Alaska commercial fishing industry

IntroductionThe purpose of this study was to identify the predictors of personal flotation device (PFD) use among workers in the Alaska commercial fishing industry.MethodsThis study analyzed data from a questionnaire administered to fishing industry workers on four types of commercial fishing vessels in Alaska. Workers’ risk perceptions of falling overboard, attitudes regarding PFDs, and other factors were compared using Chi-square tests. A forward stepwise procedure was used to fit multivariate logistic regression models predicting PFD use.ResultsPFD usage ranged from 0% reporting always using a PFD among longliners to 51% among trawlers. Among the statistically significant predictors of PFD use identified in multivariate models, the belief that PFDs were an entanglement hazard was inversely associated with any use of PFDs among longliners (OR 0.38; 95% CI: 0.20, 0.73) and gillnetters (OR 0.38; 95% CI: 0.19, 0.76). The belief that PFDs interfered with work was inversely associated with high use of PFDs among crabbers (OR 0.16; 95% CI: 0.06, 0.45) and with always using PFDs among trawlers (OR 0.35; 95% CI: 0.16, 0.78). Other significant predictors were specific to each vessel type.ConclusionsInterventions to increase PFD use in the fishing industry should be tailored to each vessel type and focus on addressing the significant barriers to PFD use. Workers may increase PFD usage if they are familiarized with newer PFDs that have been tested and accepted by their peers.

Review of Occupational Hazards Associated With Aquaculture

ABSTRACT Aquaculture is an emerging sector that is associated with most of the same hazards that are present in agriculture generally, but many fish farming tasks entail added danger, including working around water and working at night. Comprehensive studies of these hazards have not been conducted, and substantial uncertainty exists as to the extent of these hazards. The question addressed in this investigation was, “What is known about potential hazardous occupational exposures to aquatic plant and animal farmers?” In this review, causes of death included drowning, electrocution, crushing-related injury, hydrogen sulfide poisoning, and fatal head injury. Nonfatal injuries were associated with slips, trips, and falls; machines; strains and sprains; chemicals; and fires. Risk factors included cranes (tip over and power line contact), tractors and sprayer-equipped all-terrain vehicles (overturn), heavy loads (lifting), high-pressure sprayers, slippery surfaces, rotting waste (hydrogen sulfide production), eroding levees (overturn hazard), storm-related rushing water, diving conditions (bends and drowning), nighttime conditions, working alone, lack of training, lack of or failure to use personal flotation devices, and all-terrain vehicle speeding. Other hazards included punctures or cuts from fish teeth or spines, needlesticks, exposure to low temperatures, and bacterial and parasitic infections.

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.

An Analysis of Sea Kayaking Incidents in New Zealand 1992–2005

The objective of this study was to investigate trends, medical problems, and contributory factors that occurred in 50 sea kayaking incidents in New Zealand between October 1992 and September 2005. There are currently very limited validated data available worldwide about the epidemiology of sea kayaking incidents. The research will raise awareness of how these events happened and their potential for serious harm. It will assist kayakers to manage their sport safely. This was a retrospective epidemiological study of incident reports originally collected by Paul Caffyn for the Kiwi Association of Sea Kayakers (KASK). Variables investigated in this study were geographic location, month, year, participant demographics, incident severity, type of kayak and trip, environmental conditions, safety gear carried, medical problems, cause of deaths, and contributory factors. Tables and graphs were developed to analyze the results. Incidents occurred around New Zealand throughout the year, often in rough seas in offshore winds. More people were involved in September. Fifty-six percent of incidents involved groups; 20% were overseas tourists and 72% were recreational private trips. Eighty-five percent of participants were male, mostly aged 24 to 39 years old, and 48% had little or no experience. The severity of incidents increased with time. Severity was lower for women. Severity was higher in calm conditions and light winds, when the capsized kayaker became separated from the kayak, and when a personal flotation device (PFD) was not worn. Fishing incidents had a higher severity and involved inexperienced kayakers. Human factors contributed to most if not all incidents and occurred more frequently than physical events. Where medical problems were reported, hypothermia and sprains were common. Collision with a powered vessel was often fatal. The study was limited because it was based on relatively small numbers, was unlikely to capture all incidents in New Zealand, and denominator data were unknown. All incidents were complex events with many variables interacting in different ways and all had the potential to be serious and life-threatening. Human actions were more important than physical events and young men were most often involved. Staying with the kayak after capsizing and wearing a PFD may have reduced the severity of an incident.

Injury-Prevention Practices as Depicted in G- and PG-Rated Movies, 2003–2007

Our goal was to determine if the depiction of injury-prevention practices in children's movies is different from what was reported from 2 earlier studies, which showed infrequent depiction of characters practicing recommended safety behaviors. The top-grossing 25 domestic G-rated (general audience) and PG-rated (parental guidance suggested) movies per year for 2003-2007 were included in this study. Movies or scenes were excluded if they were animated, not set in the present day, fantasy, documentary, or not in English. Injury-prevention practices involving motor vehicles, pedestrians, boaters, and bicyclists were recorded for characters with speaking roles. Sixty-seven (54%) of 125 movies met the inclusion criteria for this study. A total of 958 person-scenes were examined: 524 (55%) depicted children and 434 (45%) adults. Twenty-two person-scenes involved crashes or falls, resulting in 3 injuries and no deaths. Overall, 311 (56%) of 555 motor-vehicle passengers were belted; 73 (35%) of 211 pedestrians used crosswalks; 60 (75%) of 80 boaters wore personal flotation devices; and 8 (25%) of 32 bicyclists wore helmets. In comparison with previous studies, usage of safety belts, crosswalks, personal flotation devices, and bicycle helmets increased significantly. The entertainment industry has improved the depiction of selected safety practices in G- and PG-rated movies. However, approximately one half of scenes still depict unsafe practices, and the consequences of these behaviors are rarely shown. The industry should continue to improve how it depicts safety practices in children's movies. Parents should highlight the depiction of unsafe behaviors and educate children in following safe practices.

Britain's most hazardous occupation: Commercial fishing

The main objectives of this study were to investigate the causes and circumstances of all fatal work-related accidents in the UK fishing industry from 1996 to 2005, to compare fatal accident rates with those in all other British occupations and industries and in the general British workforce, and to establish long term trends in the fatal accident rate in UK fishing since 1919. Of 160 deaths from work-related accidents in the UK fishing industry from 1996 to 2005, 86 arose from incidents involving fishing vessels and 74 were from personal accidents, with a fatal accident rate of 102 per 100,000 fishermen-years. After fishermen, the next most hazardous occupations were dockers and stevedores (28 per 100,000), refuse and salvage workers (25), agricultural machinery drivers (18), steel erectors, road construction workers (both 15), roofers (13) and scaffolders (12). The fatal accident rate among fishermen was 115 times greater than in the general British workforce, while there has been little reduction in the fatal accident rate in the UK fishing industry in the last 60 years. This study shows that commercial fishing is by far the most hazardous occupation in Britain. Prevention of fatal accidents should focus on increased use of personal flotation devices, reductions in lone fishing and the use of unstable, unseaworthy and badly maintained fishing vessels.

Arm insulation and swimming in cold water

To test whether adding insulation to the arms would improve cold water swimming performance by delaying swimming failure (SF). Novice (n = 7) and expert (n = 8) swimmers, clothed and equipped with a personal flotation device, each performed two trials in a swimming flume filled with 10 degrees C water. During free swimming (FS), subjects performed swimming until failure, followed by the Heat Escape Lessening Posture. In free swimming with additional insulation (FSA), subjects wore custom-fitted armbands. Trials ended when rectal temperature decreased to 34 degrees C or after 2 h of immersion. Measurements included: rectal and skin temperatures, heat flow, and various appraisals of swimming performance. FSA was thermally advantageous versus FS. Rectal temperature cooling rates during swimming (dT/dt Swim) were faster for FS compared to FSA (0.050 +/- 0.007 degrees C min(-1) vs. 0.042 +/- 0.006 degrees C min(-1), P < 0.01). Armbands maintained arm skin temperature about 10 degrees C warmer, for approximately 70 min (P < 0.001). Although additional insulation did not greatly improve physical performances, video analysis showed that swimming technique in FSA was maintained 10-15% better than in FS between minutes 30 and 50 (P < 0.001). SF was achieved in 5/30 trials, with increases in stroke rate (6.6 str min(-1)) and decreases in stroke length (0.24 m str(-1)) observed. In this simulation of cold water swimming survival, equipping subjects with neoprene armbands appears to have partially preserved muscle function, but with unimpressive effects on overall performance. SF is a complex entity, but is evidently related to both triceps skinfold and arm girth.

Fatal falls overboard on commercial fishing vessels in Alaska

Falls overboard are a major contributor to commercial fishing fatalities in Alaska. The National Institute for Occupational Safety and Health has repeatedly identified falls overboard as a critical issue in commercial fishing safety. This article describes the problem of falls overboard and discusses possible ways to reduce the risk factors. Data from the Alaska Occupational Injury Surveillance System on fatal falls overboard in Alaska between 1990 and 2005 were used. An in-depth descriptive analysis of these fatalities was performed to identify areas for intervention. There were 71 fatal falls overboard on commercial fishing vessels in Alaska during the 16-year time period. Falls overboard did not decline significantly during those years. The most common circumstances associated with falling overboard were working with fishing gear, being alone on deck, losing balance or slipping, heavy weather, gear entanglement, and alcohol. The level of involvement of those circumstances varied by region and gear type. Many fatal falls overboard may be prevented by understanding the circumstances involved and targeting interventions at those specific risk factors. Interventions include creating more enclosed work spaces, managing lines, avoiding fishing alone, wearing personal flotation devices and man overboard alarms, and reducing alcohol use. Subsequent research should identify further interventions for each circumstance and evaluate the effectiveness of these interventions with the fishing industry.

Self-rescue swimming in cold water: the latest advice

According to the 2006 Canadian Red Cross Drowning Report, 2007 persons died of cold-water immersion in Canada between 1991 and 2000. These statistics indicate that prevention of cold-water immersion fatalities is a significant public health issue for Canadians. What should a person do after accidental immersion in cold water? For a long time, aquatic safety organizations and government agencies stated that swimming should not be attempted, even when a personal flotation device (PFD) is worn. The objective of the present paper is to present the recent scientific evidence making swimming a viable option for self-rescue during accidental cold-water immersion. Early studies in the 1960s and 1970s led to a general conclusion that "people are better off if they float still in lifejackets or hang on to wreckage and do not swim about to try to keep warm". Recent evidence from the literature shows that the initial factors identified as being responsible for swimming failure can be either easily overcome or are not likely the primary contributors to swimming failure. Studies over the last decade reported that swimming failure might primarily be related not to general hypothermia, but rather to muscle fatigue of the arms as a consequence of arm cooling. This is based on the general observation that swimming failure developed earlier than did systemic hypothermia, and can be related to low temperature of the arm muscles following swimming in cold water. All of the above studies conducted in water between 10 and 14 degrees C indicate that people can swim in cold water for a distance ranging between about 800 and 1500 m before being incapacitated by the cold. The average swimming duration for the studies was about 47 min before incapacitation, regardless of the swimming ability of the subjects. Recent evidence shows that people have a very accurate idea about how long it will take them to achieve a given swimming goal despite a 3-fold overestimation of the absolute distance to swim. The subjects were quite astute at deciding their swimming strategy early in the immersion with 86% success, but after about 30 min of swimming or passive cooling, their decision-making ability became impaired. It would therefore seem wise to make one's accidental immersion survival plan early during the immersion, directly after cessation of the cold shock responses. Additional recommendations for self-rescue are provided based on recent scientific evidence.
