The prevention of fall from height accidents has long been a popular topic in the field of construction safety. Previous research has indicated one of the potential hazards was induced by the use of steel bracket as scaffold support. While researchers are focusing to improve the existing scaffolding system, this research introduces a newly developed device to minimize fall accidents. The workin...
Both sand and pebble beach systems in Tasmania show an overall decrease in height seaward which may be correlated with a fall of sea-level occurring while they were being formed. This fall from the postglacial Milford shoreline was of the order of 2 or 3 ft. in south-eastern Tasmania, but about 5 or 6 ft. elsewhere.
UNLABELLED Age-based differences in fall type and neuroanatomy in infants and toddlers may affect clinical presentations and injury patterns. OBJECTIVE Our goal is to understand the influence of fall type and age on injuries to help guide clinical evaluation. DESIGN/SETTING/PARTICIPANTS Retrospectively, 285 children 0-48 months with accidental head injury from a fall and brain imaging betwe...
Posterior Mediastinal Hematomas (PMHs) secondary to a fall from standing height are uncommon, with only one previous case reported in the literature. We describe a case of a 78-year-old male with multiple medical comorbidities, who was transferred to Montreal General Hospital (MGH) with a posterior mediastinal hematoma (PMH) after sustaining a fall from standing height. On initial assessment, t...
Study Design In vitro biomechanical study. Objective To investigate the biomechanics of thoracolumbar burst and Chance-type fractures during fall from height. Methods Our model consisted of a three-vertebra human thoracolumbar specimen (n = 4) stabilized with muscle force replication and mounted within an impact dummy. Each specimen was subjected to a single fall from an average height of 2.1 m...
Isolated pancreatic injury due to blunt abdominal trauma is rare and may be clinically difficult to diagnose. Parenchymal injuries may not be recognized during initial evaluation. We report the case of a 30-year-old male presented to the Emergency Department (ED) with the complaint of persistent abdominal pain, nausea, and vomiting. His medical history revealed that he fell from a height of app...
Falls from height remain the most common cause of workplace fatalities among residential construction workers, accounting for 64% of the fatalities in residential building and 100% of the fatalities among framing contractors in 2010 (BLS, 2011). Despite a recent decrease in fall incidence rates (BLS, 2011), 164 of the 1,025 carpenter apprentices surveyed (16%) reported a fall from height in the...
OBJECTIVE To describe injuries and outcomes among children who fall from a height DESIGN Prospective, convenience hospital based study. SETTING Paediatric surgical wards of Kenyatta National Hospital, Nairobi, from November 2006 to February 2007. SUBJECTS Children aged 1-13 years who sustained injuries after failing from any height. RESULTS Eighty children were recruited. There were 61 ...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
