Résistance des garde-corps en bois fixés sur des structures neuves et comportement sous charges de garde-corps métalliques fixés sur des structures existantes
Malgré les réglementations nationales et internationales qui exigent de protéger les travailleurs exposés à un risque de chute, les chutes de hauteur restent l'une des principales causes de décès pour les travailleurs de la construction. Elles sont la deuxième cause d'accidents en ce qui a trait aux coûts (397 millions de dollars par an sur la période 2010-2012) et représentent 16,1 % des décès au travail en 2017. Les garde-corps temporaires sont un moyen efficace de protection contre les chutes de...
Regulated working at heights training works and needed: studies

Occupational Fatalities Resulting from Falls in the Oil and Gas Extraction Industry, United States, 2005–2014
During 2003–2013, fatality rates for oil and gas extraction workers decreased for all causes of death except those associated with fall events, which increased 2% annually during 2003–2013 (1). To better understand risk factors for these events, CDC examined fatal fall events in the oil and gas extraction industry during 2005–2014 using data from case investigations conducted by the Occupational Safety and Health Administration (OSHA). Sixty-three fatal falls were identified, accounting for 15% of all fatal events. Among fatal falls, 33 (52%) workers fell from a height of >30...
Factors affecting fall severity from a ladder
Impact of climbing direction, gloves, gender and adaptation Ladder falls cause many fatal injuries. The factors that affect whether a ladder perturbation leads to a fall are not well understood. This study quantified the effects of several factors on a person's ability to recover from a ladder perturbation. Thirty-five participants each experienced six unexpected ladder missteps, for three glove conditions (bare hands, high friction, low friction) and two climbing directions (ascent, descent). Fall severity was increased during ladder descent (p < 0.001). Gloves did not affect fall severity...

Preventing Falls through the Design of Roof Parapets
Workers are exposed to risks from falls during construction, operation, maintenance, and demolition of buildings. Parapets are the parts of the wall assembly that extend above the roof [Rajendran and Gambatese 2013] and can prevent falls from low-sloped (flat) roofs. Other design features that can prevent falls include using guardrail systems and permanent anchor points (for use with personal fall arrest systems and lifelines) [See NIOSH 2013 for more information].

Hand breakaway strength model-Effects of glove use and handle shapes on a person's hand strength to hold onto handles to prevent fall from elevation.
This study developed biomechanical models for hand breakaway strength that account for not only grip force but also hand-handle frictional coupling in generation of breakaway strength. Specifically, models for predicting breakaway strength for two commonly-used handle shapes (circular and rectangular handles) and varying coefficients of friction (COF) between the hand and handle were proposed. The models predict that (i) breakaway strength increases with increasing COF and (ii) a circular handle with a 50.8mm-diameter results in greater mean breakaway strength than a handle with a rectangular cross...
Don’t Blow Fall Protection for the Wind Energy Industry
Vertical systems, harnesses, lanyards and climbing systems must be developed for the variety of fall hazards associated with tower construction, maintenance and rescue. The world is beginning to rely more on alternative energy, making wind power one of the largest sources of new electricity generation. As wind turbines begin to dot the landscape around the country, more workers will be required to install and service these structures. More workers on the job site means fall protection equipment designers and manufacturers must anticipate and address the unique challenges this growing industry demands...
Evaluation of safety nets by experiment-RR835
Safety nets have become a common means of providing collective protection, particularly in construction, to mitigate the effects of falls where it is impractical to use temporary edge protection. The reason for carrying out the research was to explore issues where there was doubt/concern about the performance of safety nets and their attachments. This research evaluated the effectiveness of safety nets, as used in the UK, to identify the risk (if any) of premature failure, in less than ideal conditions that could occur in the use. A series of non-ideal loading conditions involving a range of variables...
