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...
Équipements de travail pour l'exécution de travaux en hauteur
Ce dossier a pour objectif d'expliquer les consignes d'utilisation des différents équipements de travail et de protection pour les travaux en hauteur. Nous donnerons également un aperçu des moyens disponibles avec une brève description des applications et des éventuels aspects de sécurité spécifiques. L'utilisation des échelles, des différents types d'échafaudages, des élévateurs à ciseaux, d'autres types d'élévateurs ainsi que l'utilisation d'une...
Straight ladder inclined angle in a field environment
The relationship among actual angle, method of setup and knowledgee Ladder inclined angle is a critical factor that could lead to a slip at the base of portable straight ladders, a major cause of falls from heights. Despite several methods established to help workers achieve the recommended 75.5° angle for ladder setup, it remains unclear if these methods are used in practice. This study explored ladder setup behaviors in a field environment. Professional installers of a company in the cable and other pay TV industry were observed for ladder setup at their worksites. The results showed that...
Effects of foot placement, hand positioning, age and climbing biodynamics on ladder slip outcomes
Ladder falls frequently cause severe injuries; yet the factors that influence ladder slips/falls are not well understood. This study aimed to quantify (1) the effects of restricted foot placement, hand positioning, climbing direction and age on slip outcomes, and (2) differences in climbing styles leading to slips versus styles leading to non-slips. Thirty-two occupational ladder users from three age groups (18-24, 25-44 and 45-64 years) were unexpectedly slipped climbing a vertical ladder, while being assigned to different foot placement conditions (unrestricted vs. restricted toe clearance) and...
Researchers Count 113 Work-Related Ladder Fatalities in 2011
A paper published in the April 24 edition of CDC's Morbidity and Mortality Weekly Report is an evaluation of injuries and deaths resulting from work-related falls from ladders. The authors analyzed data from several injury surveillance systems and calculated there were 113 fatal falls, an estimated 15,460 non-fatal injuries resulting in at least one day of lost time, and 34,000 non-fatal injuries treated in hospital emergency departments in 2011 alone. They conclude that ladder fall injuries (LFIs) represent a substantial public health burden of preventable injuries for workers and there is...
Research to improve extension ladder angular positioning
A leading cause for extension ladder fall incidents is a slide-out event usually related to suboptimal ladder inclination. An improved ladder positioning method or procedure could reduce the risk of ladder stability failure and the related fall injury. The objective of the study was to comparatively evaluate the effectiveness of a multimodal angle indicator with other existing methods for extension ladder angular positioning. Twenty experienced and 20 inexperienced ladder users participated in the study. Four ladder positioning methods were tested in a controlled laboratory environment with 4.88...
Prévention des risques de chutes de hauteur
Face aux situations dangereuses posées par le travail en hauteur, une démarche de prévention adaptée s'impose. Cette nouvelle brochure réalisée conjointement par l'INRS et l'OPPBTP (référence ED 6110) fait le point sur cette problématique. Son objectif : aider les entreprises à faire leur choix parmi les équipements de protection disponibles. Source : http://www.inrs.fr/accueil/header/actualites/brochure-risque-chute-hauteur.html
Gripping control rather than just contact is critical for ladder climbing
This article asserts that the proper use of the three-point control ladder climbing strategy could prevent many of these ladder fall injuries and deaths. In addition to discussing principles of effective three-point control, the article reviews recommendations for design and process changes needed to better protect workers using ladders or stairs. The author maintains that three-point contact is an unsound means of positioning the body on a ladder or horizontal access route. To reasonably prevent uncontrolled falls, and prevent stepladder tipping, one hand must be able to grasp efficiently in a...
Ladder Use in Construction Guideline
Workers on construction sites continue to fall from ladders and become critically injured or killed. The Provincial Labour-Management Health and Safety Committee (PLMHSC) has prepared a guideline on safe ladder use in construction to assist workplace parties in understanding their obligations under the OHSA and its regulations. The Ministry of Labour views the guideline as a recommended set of industry best practices that may be used as part of an employer's health and safety program.
