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 hauteur, par ailleurs, s'agissant d'un moyen de protection passif, ils permettent de maintenir une productivité élevée. [...] En ce qui concerne les garde-corps en bois installés sur des solives ajourées ou murs préfabriqués (lors de la construction du bâtiment), aucune étude n'a été menée à ce jour, il est donc difficile de s'assurer de leur résistance aux charges prescrites par le Code de sécurité pour les travaux de construction (CSTC) en vigueur au Québec. Pour les garde-corps métalliques généralement utilisés pour les travaux d'étanchéité sur des bâtiments existants, la résistance dépendra du fond de vissage, qui est souvent inconnu de l'entrepreneur. Il est possible d'effectuer une estimation de la résistance des garde-corps métalliques en se basant sur des formules empiriques caractérisant la résistance à l'arrachement des vis. Cependant, la variabilité de la résistance à l'arrachement établie selon ces formules empiriques peut être importante. De plus, les conditions du bois in situ sont la plupart du temps inconnues (type de bois, humidité, pourrissement, présence de nœuds). Ainsi, la résistance de la fixation de garde-corps sur des structures réelles est très souvent approximative. Les objectifs des travaux de recherche sont (i) de vérifier la résistance des garde-corps en bois fixés sur des structures neuves reconstituées en laboratoire, de type solives ajourées, (ii) de vérifier la résistance des garde-corps en bois fixés sur mur préfabriqué reconstitué en laboratoire, (iii) de comparer le comportement sous charges de garde-corps métalliques installés sur des toits plats de structures existantes de différents âges. Lors de cette étude, 262 essais de résistance sur des garde-corps en bois construits à partir de 2 po x 4 po et fixés sur des solives ajourées ont été réalisés en laboratoire. Ces essais ont permis d'analyser l'influence des variables suivantes : hauteur du garde-corps (1 m ou 1,2 m), hauteur de la solive (9,5 po, 12 po, 14 po, 16 po), configuration d'essai (1 travée, 3 travées, 2 travées avec force appliquée directement sur le montant), et types de fixation (à l'aide de clous lisses, clous annelés, clous vrillés, vis à bois, tirefonds). L'influence de ces paramètres a aussi été étudiée en laboratoire lors de 98 essais de résistance pour des garde-corps en bois fixés sur un mur préfabriqué construit à partir de 2 po x 4 po. Au cours de ces essais sur solives ajourées et sur mur préfabriqué, la force horizontale était appliquée sur la lisse supérieure du garde-corps à l'aide d'un treuil manuel et mesurée à l'aide d'une cellule de charge et d'un système d'acquisition des données avec une fréquence de 10 Hz. La charge verticale était un poids mort appliqué sur la lisse supérieure du garde-corps. Enfin, 36 essais ont été réalisés sur le terrain avec des garde-corps métalliques installés sur des structures réelles : deux bâtiments (l'un de 2008 et l'autre de 2013), et quatre parapets différents (dimensions et construction différentes), tous en bon état avant les essais (taux d'humidité inférieur à 10 % et absence de dommage apparent). Trois modèles de garde-corps métalliques ont été mis à l'essai, dont deux avaient déjà fait l'objet d'une étude précédente en laboratoire. Pour ces garde-corps, plusieurs moyens de fixation sur les parapets ont été étudiés : fixation sur une face ou deux faces (avec serre-parapet ou plaque stabilisatrice), différents types de vis (vis noire, vis autotaraudeuse et tirefonds) [...]

Regulated working at heights training works and needed: studies

Special Report
Two recently released Ontario studies demonstrate why mandatory, standardized working at heights training is so critical to worker well-being. 
One study undertaken by the Institute for Work & Health (IWH) conducted an evaluation of the impact the province's working at heights training standard had on workers and their work sites. A second and earlier probe prepared by the Ministry of Labour (MOL) for the Chief Prevention Officer undertook root cause analysis of worker deaths from falls from heights.
Significant results from WAH training standard
The IWH evaluation consisted of surveys with working at heights training participants, training providers and employers in construction. Interviews with MOL inspectors, an examination of MOL administrative records and lost-time workers' compensation claims were also taken into account.

Vêtements de protection en salle blanche, une performance parfois compromise

Une étude récente révèle que que les vêtements réutilisables sont vulnérables aux dommages causés par le blanchissage et la stérilisation.

Les vêtements réutilisables utilisés dans la production stérile et aseptique nécessitent des cycles répétés de lavage et de stérilisation pour maintenir leur efficacité, en utilisant des techniques telles que l'irradiation gamma. Les données de propriétés physiques sont souvent disponibles pour les nouveaux vêtements de salles blanches : cependant, elles le sont moins tout au long du cycle de vie du vêtement. Une étude réalisée par DuPont vise à combler cette lacune d'information.

A 10-year descriptive analysis of UK Maritime and Coastguard data on lifejacket use and drowning prevention

The study investigated if incidences of death by drowning in the UK could have been prevented through the use of lifejackets over a ten year period. This study was a retrospective analysis of fatal maritime incident data collected by the Maritime and Coastguard Agency (MCA) between the years 2007 and 2016. A Casualty Review Panel (CRP) met annually to categorise incidents into five groups based on the likelihood of a lifejacket preventing death. Descriptive analyses were performed on the overall fatalities, data were stratified by year, sex, age, and activity. Ten year data were categorised based on the outcome of the CRP, these data were further stratified by year and activity, with trends being reported. Potentially 180 lives (82% of all cases successfully categorised) could have been saved if a lifejacket had been worn. An 18% reduction in the number of cases referred to the CRP was observed from the first 5?years (2007–2011?=?59% of all referrals) to the last 5?years (2007–2011?=?41% of all referrals), with 42% less cases referred in 2016 compared to 2007. The data generated by the CRP over the ten years has provided a unique insight into coastal deaths, it has provided a clear rationale for the use of lifejackets and has helped target national and activity-specific campaigns for water safety and lifejacket use.

Slips, Trips, and Falls Among Home Care Aides

A Mixed-Methods Study
Objective: To address the gap of knowledge about slips, trips, and falls (STFs) among home care aides (HCAs) who work in clients' homes.
Methods: This mixed method study used survey and focus group data of HCAs in a Medicaid-funded homecare program.
Results: STFs were common with over 12% of HCAs reporting occurrence in the previous 12 months, of whom 58% fell to the ground. Both survey and focus group data identified ice, clutter, workload, rushing and other hazards. Focus group data explained the reasons for not reporting STFs, even among those who sustained injury, and added HCAs' voices to the understanding of causes, consequences and prevention strategies for STFs.
Conclusions: Empowering HCAs with knowledge, training, and involvement may transform “near miss” STFs into opportunities to prevent STFs among care workers and their clients.

Risk of self-contamination during doffing of personal protective equipment

Background: The aim of this study was to describe the risk of self-contamination associated with doffing of personal protective equipment (PPE) and to compare self-contamination with various PPE protocols.
Methods: We tested 10 different PPE donning and doffing protocols, recommended by various health organizations for Ebola. Ten participants were recruited for this study and randomly assigned to use 3 different PPE protocols. After donning of PPE, fluorescent lotion and spray were applied on the external surface of the PPE to simulate contamination, and ultraviolet light was used to count fluorescent patches on the skin.
Results: After testing 30 PPE sequences, large fluorescent patches were recorded after using “WHO coverall and 95” and “North Carolina coverall and N95” sequences, and small patches were recorded after using “CDC coverall and N95” and “Health Canada gown and N95” sequences. Commonly reported problems with PPE use were breathing difficulty, suffocation, heat stress, and fogging-up glasses. Most participants rated PPE high (18/30) or medium (11/30) for ease of donning/doffing and comfort. PPE sequences with powered air-purifying respirators (PAPRs) and assisted doffing were generally associated with fewer problems and were rated the highest.
Conclusion: This study confirmed the risk of self-contamination associated with the doffing of PPE. PAPR-containing protocols and assisted doffing should be preferred whenever possible during the outbreak of highly infectious pathogens.

Identification and Characterization of Failures in Infectious Agent Transmission Precaution Practices in Hospitals

A Qualitative Study
Importance: Using personal protective equipment (PPE) and transmission-based precautions are primary strategies for reducing the transmission of infectious agents.
Objective: To identify and characterize failures in transmission-based precautions, including PPE use, by health care personnel that could result in self-contamination or transmission during routine, everyday hospital care.
Design, Setting, and Participants: This qualitative study involved direct observation inside and outside patient rooms on clinical units from March 1, 2016, to November 30, 2016. Observations occurred in the medical and/or surgical units and intensive care units at an academic medical center and a Veterans Affairs hospital, as well as the emergency department of the university hospital. Trained observers recorded extensive field notes while personnel provided care for patients in precautions for a pathogen transmitted through contact (eg, Clostridium difficile, methicillin-resistant Staphylococcus aureus) or respiratory droplet (eg, influenza). Specific occurrences involving potential personnel self-contamination were identified through a directed content analysis. These occurrences were further categorized, using a human factors model of human error, as active failures, such as violations, mistakes, or slips.
Conclusions and Relevance: Active failures in PPE use and transmission-based precautions, potentially leading to self-contamination, were commonly observed. The factors that contributed to these failures varied widely, suggesting the need for a range of strategies to reduce potential transmission risk during routine hospital care.

Preventing falls: Choosing compatible Fall Protection Supplementary Devices (FPSD) for bridge maintenance work using virtual prototyping

Apart from struck-by safety incidents, fall-related injuries are a major concern in bridge maintenance work. To protect against falls from bridge decks, maintenance workers largely rely on existing bridge guardrails. However, a large number of bridge guardrails do not comply with the regulatory height requirement of 42 ± 3 in. for sufficient fall protection – although appropriate for vehicular traffic. To address this fall protection issue, a few departments of transportation (DOTs) have adopted Fall Protection Supplementary Devices (FPSDs). These devices are temporarily installed on existing bridge guardrails to sufficiently increase the barrier height while work is performed on bridge decks. However, not all FPSDs are compatible with every bridge guardrail. Therefore, to provide sufficient protection, DOT decision makers are tasked with identifying FPSDs that are compatible for each guardrail application. This generally has involved physically installing FPSDs and assessing compatibility on a trial-and-error basis. The use of such inefficient techniques have resulted in significant errors, wasted resources, productivity losses, and an increased likelihood of struck-by safety incidents. To address this issue, the objective of this study is to propose an efficient, cost-effective, and safe approach to assessing compatibility using virtual prototyping methods. In addition, to illustrate the use of the proposed method, a case example of the compatibility testing between two bridge guardrails in North Carolina and three separate FPSDs is presented. It is expected that the proposed method will provide a useful mechanism for DOTs to select suitable FPSDs to protect their workforce.

Chemical, Biological, Radiological, and Nuclear (CBRN) Respiratory Protection Handbook

Since 2001, the U.S. Department of Health and Human Services (HHS), Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH) has established performance and design standards for respiratory protective devices (RPDs) to protect against chemical, biological, radiological, and nuclear (CBRN) hazards and toxic industrial chemicals. Prior to 2001, there were no standards for the use of RPDs by U.S. emergency response personnel that covered the full range of expected CBRN threats. Federal regulations require emergency response personnel to use respirators approved by NIOSH for the expected hazards. Equipment performance standards were needed to protect against CBRN threats. Neither industrial nor military respirators provided protection from all potential CBRN respiratory hazards. Several federal agencies partnered to provide research and testing to produce the necessary standards: Department of Justice (DOJ); Department of Homeland Security (DHS); Department of Defense (DoD), U.S. Army Research, Development and Engineering Command (RDECOMa); Department of Commerce (DOC), National Institute for Standards and Technology (NIST); and the Department of Labor (DOL), Occupational Safety and Health Administration (OSHA).

ASTM F2130 - 11(2018) - Standard Test Method for Measuring Repellency, Retention, and Penetration of Liquid Pesticide Formulation Through Protective Clothing Materials

Significance and Use: This test method can be used for laboratory screening of protective clothing material used to manufacture garments and accessories worn by pesticide workers. This test method can be used for the development and evaluation of new protective clothing materials. This test method can be used for the evaluation of protective clothing materials against new pesticide formulations.
Scope: This test method measures repellency, retention, and penetration of a known volume of liquid pesticide when applied to protective clothing material. No external hydrostatic or mechanical pressure is applied to the test specimen during or after the application of the liquid pesticide. This test method is designed to measure performance of protective clothing materials at two levels of contamination. Low level of contamination is achieved by applying 0.1 mL liquid formulation and high level by applying 0.2 mL. This test method does not measure resistance to permeation or degradation. This test method is suitable for field-strength pesticide formulations. This test method may not be suitable for testing protective clothing materials against volatile pesticides.

Influences on use of hand moisturizers in nurses

Background: Nurses are at high risk of hand dermatitis. Regular hand moisturizing can prevent dermatitis, but nurses' use of hand moisturizers is suboptimal.
Aims: To establish (i) what beliefs about hand dermatitis and hand moisturizer use are associated with hand moisturizer use by nurses at home and at work and (ii) if hand moisturizer use behaviours in nurses are associated with the prevalence of hand dermatitis.
Methods: We used a questionnaire to investigate nurses' knowledge, beliefs and behaviours regarding hand dermatitis and use of hand moisturizers.
Results: The response rate was 55/65 (85%). Forty-two (76%) participants agreed that applying hand moisturizers reduced the risk of dermatitis, and 53 (96%) agreed that dermatitis increased the risk of skin carrying pathogenic organisms. Frequent moisturizer application was associated with beliefs that it was part of the nurse's role to apply hand creams, a belief that they had had training in the use of moisturizers and believing that patients approved of them moisturizing their hands.
Conclusions: Hand moisturizer use by nurses can be improved by enhancing their beliefs that it is part of their professional role to apply hand cream regularly.
