Dungeness crab fishermen perceptions of injury causation and factors in staying safe
Background: Commercial fishing is a hazardous occupation in the United States (US). Injury surveillance data relies heavily on US Coast Guard reports, which capture injuries severe enough to require reporting. The reports do not incorporate the fishermen’s perspective on contributing factors to injuries and staying safe while fishing.
Materials and methods: We conducted a pre-season survey of Dungeness crab fishermen during 2015 to 2016. Community researchers administered surveys to fishermen. Respondents reported their opinions about factors contributing to injuries and staying safe, which were grouped into similar themes by consen- sus. Descriptive statistics were calculated to explore the number of injuries, crew position, age, and years of experience. Chi-square tests compared perceptions of injury causation, staying safe, and other factors.
Results: Four hundred twenty-six surveys were completed. Injury causation perceptions were sorted into 17 categories, and staying safe perceptions were sorted into 13 categories. The most frequently cited causes of injury were heavy workload (86, 21.9%), poor mental focus (78, 19.9%), and inexperience (56, 14.3%). The most frequently cited factors in staying safe while fishing were awareness (142, 36.1%), good and well-maintained fishing gear/vessel (41, 10.4%), and best marine practices (39, 9.9%). Opinions were not significantly associated with experiencing an injury in the past while fishing, but some opinions were significantly associated with crew position, age, and years of experience.
Conclusions: The perceptions of fishermen can be evaluated further and incorporated into training or intervention development. The fishermen-led approach of this project lends itself to developing injury pre- vention strategies that are effective, realistic and suitable. The resources available at FLIPPresources.org, such as informational sheets for new fishermen, sample crew agreements, and first aid kit resources, supply workers in this fishery with real solutions for issues they identified through their survey responses.

Safety voice for ergonomics (SAVE) project: protocol for a workplace cluster-randomized controlled trial to reduce musculoskeletal disorders in masonry apprentices
Background:
Masons have the highest rate of overexertion injuries among all construction trades and rank second for occupational back injuries in the United States. Identified ergonomic solutions are the primary method of reducing exposure to risk factors associated with musculoskeletal disorders. However, many construction workers lack knowledge about these solutions, as well as basic ergonomic principles. Construction apprentices, as they embark on their careers, are greatly in need of ergonomics training to minimize the cumulative exposure that leads to musculoskeletal disorders. Apprentices receive safety training; however, ergonomics training is often limited or non-existent. In addition, apprenticeship programs often lack “soft skills” training on how to appropriately respond to work environments and practices that are unsafe. The SAVE program – SAfety Voice for Ergonomics – strives to integrate evidence-based health and safety training strategies into masonry apprenticeship skills training to teach ergonomics, problem solving, and speaking up to communicate solutions that reduce musculoskeletal injury risk. The central hypothesis is that the combination of ergonomics training and safety voice promotion will be more effective than no training or either ergonomics training alone or safety voice training alone.
Methods/design:
Following the development and pilot testing of the SAVE intervention, SAVE will be evaluated in a cluster-randomized controlled trial at 12 masonry training centers across the U.S. Clusters of apprentices within centers will be assigned at random to one of four intervention groups (n = 24 per group): (1) ergonomics training only, (2) safety voice training only, (3) combined ergonomics and safety voice training, or (4) control group with no additional training intervention. Outcomes assessed at baseline, at the conclusion of training, and then at six and 12 months post training will include: musculoskeletal symptoms, general health perceptions, knowledge of ergonomic and safety voice principles, and perception and attitudes about ergonomic and safety voice issues.
Discussion:
Masons continue to have a high rate of musculoskeletal disorders. The trade has an expected increase of 40 % in the number of workers by 2020. Therefore, a vetted intervention for apprentices entering the trade, such as SAVE, could reduce the burden of musculoskeletal disorders currently plaguing the trade.Keywords: Safety voice, Ergonomics, Masons, Construction industry, Injury prevention, Apprenticeship trainin

Injury Risk Perception of Commercial Dungeness Crab Fishermen
The Fishermen Led Injury Prevention Program is the first and only research focused on non-fatal injury prevention among commercial fishermen.
• No fishermen reported that they had zero chance of injury, regardless of injuries sustained in career and/or in the past year.
• Fishermen who have sustained an injury in their career and/or in the past year, have a higher perception of injury risk.
• There is no connection between a fisherman’s history with injury and the amount they worry about sustaining an injury.• Commercial fishing is one of the most dangerous professions in the United States.
• Between 2002-2014 Dungeness crab fishermen had 209 fatalities per 100,000 full-time equivalent workers.
• 405 surveys were collected by community researchers before the 2015-2016 Dungeness crab season.
• We examine here the association of injury and risk perception

Occupational exposure to extremely low frequency magnetic fields and brain tumour risks in the INTEROCC study
BACKGROUND: Occupational exposure to extremely low frequency magnetic fields (ELF) is a
suspected risk factor for brain tumours, however the literature is inconsistent. Few studies have
assessed whether ELF in different time windows of exposure may be associated with specific
histologic types of brain tumours. This study examines the association between ELF and brain
tumours in the large-scale INTEROCC study.
METHODS: Cases of adult primary glioma and meningioma were recruited in seven countries
(Australia, Canada, France, Germany, Israel, New Zealand, United Kingdom) between 2000 and
2004. Estimates of mean workday ELF exposure based on a job exposure matrix assigned.
Estimates of cumulative exposure, average exposure, maximum exposure, and exposure duration
were calculated for the lifetime, and 1-4, 5-9, and 10+ years prior to the diagnosis/reference date.
RESULTS: There were 3,761 included brain tumour cases (1,939 glioma, 1,822 meningioma) and
5,404 population controls. There was no association between lifetime cumulative ELF exposure
and glioma or meningioma risk. However, there were positive associations between cumulative
ELF 1-4 years prior to the diagnosis/reference date and glioma (odds ratio (OR) ≥ 90th percentile
vs < 25th percentile = 1.67, 95% confidence interval (CI) 1.36-2.07, p < 0.0001 linear trend), and,
somewhat weaker associations with meningioma (OR ≥ 90th percentile vs < 25th percentile =
1.23, 95% CI 0.97-1.57, p = 0.02 linear trend).
CONCLUSIONS: Results showed positive associations between ELF in the recent past and glioma.
IMPACT: Occupational ELF exposure may play a role in the later stages (promotion and
progression) of brain tumourigenesis.Keywords: glioma, meningioma, occupation, case control study, extremely low frequency magnetic field

Efficacy of text messaging apprentices to reinforce ergonomics and safety voice training.
INTRODUCTION: Injuries and work-related musculoskeletal disorders (MSDs) are common among masons. SAfety Voice for Ergonomics (SAVE) integrates training in ergonomic and safety problem-solving skills into masonry apprenticeship training. The purpose of this study was to assess the efficacy of text messaging to reinforce SAVE program content.
METHOD: SAVE effectiveness was evaluated at masonry apprenticeship training centers across the United States by comparing three experimental groups: (1) Ergonomics training, (2) Ergonomics and Safety Voice training, and a (3) Control. Apprentices received SAVE training with their standard instruction. To reinforce classroom training, refresher training was implemented by sending weekly text messages for six months. Half of the text messages required a response, which tested knowledge or assessed behavior, while the remaining reiterated knowledge. Apprentices (n = 119) received SAVE text messages. Response rates and percentage of correct responses were compared with chi-square tests and independent group t-tests. Multivariable logistic regression analysis predicted apprentice response with selected demographic and work experience variables. Finally, feedback on of the use of text messaging was obtained.
RESULT: Of 119 participants, 61% (n = 72) responded to at least one text message. Logistic regression revealed that being a high school graduate and a brick and block mason significantly affected the odds of responding. Sixty-nine percent of apprentices agreed that text messages reinforced SAVE content.
CONCLUSION: Even though there was no training center requirement to respond, the high response rate suggests that text messaging can effectively be used to reinforce ergonomics and safety voice training for both knowledge and behavior. Practical Application: The prevalent use of text messaging creates opportunities to reinforce health and safety training and engage workers, especially for populations that may be at various locations over time such as construction sites. Instructors and practitioners should consider the utility of text messaging for supporting their training and safety programs

Silicone Wristbands as Personal Passive Samplers
Active-sampling
approaches are commonly used for personal monitoring,
but are limited by energy usage and data that may not represent an
individual’s exposure or bioavailable concentrations. Current
passive techniques often involve extensive preparation, or are developed
for only a small number of targeted compounds. In this work, we present
a novel application for measuring bioavailable exposure with silicone
wristbands as personal passive samplers. Laboratory methodology affecting
precleaning, infusion, and extraction were developed from commercially
available silicone, and chromatographic background interference was
reduced after solvent cleanup with good extraction efficiency (>96%).
After finalizing laboratory methods, 49 compounds were sequestered
during an ambient deployment which encompassed a diverse set of compounds
including polycyclic aromatic hydrocarbons (PAHs), consumer products,
personal care products, pesticides, phthalates, and other industrial
compounds ranging in log <i>K</i><sub>ow</sub> from −0.07
(caffeine) to 9.49 (tris(2-ethylhexyl) phosphate). In two hot asphalt
occupational settings, silicone personal samplers sequestered 25 PAHs
during 8- and 40-h exposures, as well as 2 oxygenated-PAHs (benzofluorenone
and fluorenone) suggesting temporal sensitivity over a single work
day or week (<i>p</i> < 0.05, power =0.85). Additionally,
the amount of PAH sequestered differed between worksites (<i>p</i> < 0.05, power = 0.99), suggesting spatial sensitivity

Prevalence of work-related musculoskeletal pain in masonry apprentices.
The construction industry, specifically masonry, reports more work-related musculoskeletal disorders (WMSD) rates than the general industry. Masonry apprentices are assumed to be healthy, yet may have WMSDs. The purpose of this study was to evaluate the prevalence of musculoskeletal symptoms (MSS), time loss, and healthcare use among apprentices. 183 brick and block masonry apprentices completed surveys on demographics, work history, MSS, and functional well-being. The prevalence of MSS was calculated by body region, time loss, and healthcare use. The relationship between MSS, and perceived global physical and mental health was assessed. Approximately 78% of apprentices reported MSS, most in several body regions. Low back and wrists/hands were most prevalent, although few missed work or sought healthcare. Lower functional health and well-being was reported. Apprentices reported MSS comparable to previous studies of journey-level masons. Apprenticeship programmes could integrate ergonomics education to help apprentices develop safety culture early in their careers
