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...

Twenty years of workers' compensation costs due to falls from height among union carpenters, Washington State
BACKGROUND: Falls from height (FFH) are a longstanding, serious problem in construction. METHODS: We report workers' compensation (WC) payments associated with FFH among a cohort (n = 24,830; 1989-2008) of carpenters. Mean/median payments, cost rates, and adjusted rate ratios based on hours worked were calculated using negative-binomial regression. RESULTS: Over the 20-year period FFH accounted for $66.6 million in WC payments or $700 per year for each fulltime equivalent (2,000 hr of work). FFH were responsible for 5.5% of injuries but 15.1% of costs. Cost declines were...

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].

Application of scaled world model for usability testing of fall arrest system in residential construction
Falls from heights in residential construction continue to be a leading cause of fatalities and severe injuries. Field studies are difficult to implement in residential construction, because companies are hesitant to allow observers on site to collect data while tasks are being conducted. Use of scaled world models has been recommended for experimental contexts that require high levels of ecological validity as well as internal (control) validity . In this project, we explored several attributes to design a scaled world model of residential roofing that would support controlled trials to evaluate...
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...
Analysis of the safety conditions of scaffolding on construction sites
This paper presents the results of a study whose aim was to analyse the safety conditions of supported scaffolds (i.e., ground supported scaffolding). In 2007 the authors examined the scaffolding erected on 105 building sites in Spain. The study provides a qualitative assessment of the safety conditions of bracings, anchor ties, toe-boards, guardrails, ladders, struts, long beams, cross beams, platforms, supports, etc. In the European Union there are no legal requirements for the manufacturers of supported scaffolds, but there are some regulations on the use of this type of scaffolding on construction...
Garde-corps sur toits plats : pour mieux prévenir les chutes
Tout travail en hauteur comporte des risques importants de chute pour les travailleurs. Pour prévenir ce type d’accidents, l’installation d’un garde-corps demeure le moyen de protection collective contre les chutes le plus approprié sur les toits plats. Or, les systèmes d’ancrage des garde-corps utilisés au Québec n’avaient jamais fait l’objet d’essais afin de déterminer s’ils étaient conformes au Code de sécurité pour les travaux de construction. Après avoir considéré...

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...
Identifying fall-protection training needs for residential roofing subcontractors
Falls remain the leading cause of injuries and fatalities in the small residential roofing industry and analogous investigations are underrepresented in the literature. To address this issue, fall-protection training needs were explored through 29 semi-structured interviews among residential roofing subcontractors with respect to recommendations for the design of fall-protection training. Content analysis using grounded theory was conducted to analyze participants' responses. Results of the analysis revealed six themes related to the design of current fall-protection training: (1) barriers...
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.
