Guidance on Safety in Concrete Pumping

The aim of this guidance is to improve standards of safety during concrete pumping and reduce the incidence of collapse of concrete pump rigs and injuries due to incidents involving pressurisation of pipework or other equipment.

As with all construction equipment, the safe operation of concrete pumps depends on a number of factors including the selection and maintenance of the pump and placing boom, the planning and supervision of their
use and the competence of the operator and other personnel. If any of these are deficient, the risk of a serious accident increases significantly, so it is essential that site managers ensure that all concrete pumping operations are planned, supervised and carried out safely.

Fault tree analysis and risk mitigation strategies for mine hoists

Mine hoist are an essential part of an underground mine. In addition to extracting the ore from the mine, this machine transports the miners from the surface to the various underground levels of the mine. The two main hazards to which minors in the cage are exposed to are rope severance and loss of control of the hoisting machine. In both cases, the risk is the crashing of the cage at one end of the shaft. Hoisting accident and fatalities are rare but still happen despite the use of safety catches to retain the cage in the event of rope severance. The objective of this article is to improve mine hoist safety and to prevent the crash of a cage (of more generally any conveyance) at the shaft boundaries. Fault Trees (FT) are used to analyze the accidents scenarios of a cage crash in a shaft. Two generic fault trees are presented: one based on rope severance and the other based on loss-of-control of the conveyance. Results of the study indicate that, in the case of a rope severance, most of the root causes are based on secondary failure of the safety catches. In the case of a loss-of-control of the conveyance, most of the root causes are based on command failures that prevent the cage from stopping before reaching the shaft boundaries. This article suggests general mitigation measures and recommends the use of machinery safety standards in order to improve the reliability of hoisting machines.

Hazardous Energy Control (Lockout and Other Means)

It is a matter of life and death. Hazardous energy control is more than Lockout. It encompasses Machine Guarding, Alternative Measures (alternative guarding arrangement that prevents exposure to hazardous energy), Lockout, and other methods of ensuring worker safety from contact with hazardous energy. Here you will find information on regulatory requirements, general guidance and procedures that your company can use to implement an effective Hazardous Energy Control (Lockout/Tagout) Program and prevent unexpected energizing, start-up or release of stored energy which could cause serious injury or death to workers. Injuries related to Lockout often occur when an employee services or repairs a machine or tries to clear a jam but fails to de-energize the machine and lockout sources of energy.  Problems can also occur during the process of re-energizing.
Sources of energy are not only electrical; they can also include mechanical, hydraulic, pneumatic, chemical, thermal, or other sources of energy. The failure to develop and use hazardous energy control (Lockout) procedures is one of OSHA's annual top 10 most frequently cited workplace safety violations. Injuries and fatalities that happen for failure to implement a Lockout Program are much more costly than the citations (not only in economic terms). A comprehensive, written, diligently planned and executed Hazardous Energy Control (Lockout) Program protects the life, and the safety and health of workers; it is a very important part of machine maintenance and production servicing operations.

Ponts roulants - Manuel de sécurité

Longtemps restée dans le domaine de l'empirisme, l'utilisation des engins fait aujourd'hui l'objet de règles nombreuses touchant à la fois au choix, aux vérifications et à la maintenance du matériel, à la formation du personnel, ainsi qu'à la conduite proprement dite.
C'est pourquoi ce manuel comprend deux parties : l'une consacrée aux aspects purement réglementaires, l'autre plus spécifiquement dédiée aux règles de bonnes pratiques en matière de conduite d'engins.
Un large public pourra ainsi trouver dans ce manuel les références qui lui seront nécessaires : chefs d'établissements, chargés de sécurité, formateurs, et bien sûr les conducteurs eux-mêmes (pontiers, conducteurs de ponts roulants, de portiques et semi-portiques).

Tower crane safety on construction sites: A complex sociotechnical system perspective

Tower crane is the lifeline of the construction industry, but tower crane accidents are still too frequent. Despite the significant progress in tower crane safety research, system thinking-based approaches are lacking. The aim of this paper is to analyze tower crane safety from a complex sociotechnical system perspective through implementing both qualitative and quantitative analysis methods. Characteristics of five tower crane safety system components are summarized with a new framework comprised of five system-based levels based on Rasmussen's risk management theory. Fifty-six contributing factors of tower crane safety were identified. The AcciMap technique was applied to qualitatively build a generic model for tower crane safety, which comprehensively presents the systems levels and casual paths of the contributing factors. A survey was conducted to quantitatively research the tower crane safety system. Nine main dimensions and 25 critical factors were found pertaining to the tower crane safety system. These results provide a new lens for tower crane safety and contribute new systems thinking applications in tower crane safety management.

Literature review on the incentives and solutions for the bypassing of guards and protective devices on machinery

Bypassing guards and protective devices on machinery can lead to serious and fatal accidents. The aim of this paper is to conduct a comprehensive review that sheds light on the definition of bypassing, related regulations and standards, workers' incentives to bypass, and possible solutions to overcome this issue. The review generated 72 incentives to bypass guards and protective devices and 82 solutions. Some of the most frequent incentives included the necessity to remove safeguards in order to perform activities (e.g. adjustment, troubleshooting, maintenance, and installation), a lack of visibility, failures and a lack of reliability of the safeguards. This literature analysis suggests classifying the incentives into five categories: ergonomics, productivity, machine or safeguarding, behavior, and corporate climate. The solutions, which are related to the design, manufacturing, and usage phases, are classified into technical, organizational, and individual factors. These are all factors that influence the prevention of bypassing. The review shows that there is a lack of an integrated tool to prevent bypassing. This paper serves as a foundation to develop such a tool, as well as to provide useful insights into the incentives for bypassing, as well as preventive solutions that could be used as a guideline for researchers and OHS preventionists.

Estimation of probability of harm in safety of machinery using an investigation systemic approach and Logical Analysis of Data

In safety of machinery, estimating the probability of occurrence of harm is a recurrent problem. This paper proposes and applies a new method to estimate that probability. Information regarding accidents involving machinery that is gathered and analyzed by experts is formatted based on a systemic-inspired model using the MELITO concept. Then, Logical Analysis of Data (LAD) is used to extract knowledge automatically to characterize accidents. MELITO describes the context in which the accident has occurred, gathering information about the moment (M), equipment (E), location (L), individual (I), task (T) and organization (O). LAD is a data mining algorithm that infers knowledge learning from a database. In this paper, a case study consisting of twenty-three fatal and serious accident reports involving belt conveyors is presented. Data on these accidents is classified according to MELITO. The inferred knowledge is presented in the form of interpretable patterns that characterize and distinguish fatalities from non-fatal harm. Each pattern consists of a Boolean equation from MELITO and covers a subset of accidents. Based on each pattern, the probability of the occurrence of harm related to a hazardous situation is estimated. Such probability is useful in monitoring risk behavior after the occurrence of a new accident, for instance.

Worker safety and injury severity analysis of earthmoving equipment accidents

Introduction: Research on construction worker safety associated with construction equipment has mostly focused on accident type rather than injury severity and the embedded factor relationships. Significant variables and their effects on the degree of injury are examined for earthmoving equipment using data from OSHA. Four types of equipment, backhoe, bulldozer, excavator, and scraper are included in the study. Accidents involving on-foot workers and equipment operators are investigated collectively, as well as separately. Methods: Cross tabulation analysis was conducted to establish the associations between selected categorical variables, using degree of injury as a dichotomous dependent variable (fatal vs. nonfatal) and a number of independent variables having different values. Odds ratios were calculated to determine how much a certain variable/factor increases the odds of fatality in an accident, and the odds ratios were ranked to determine the relative impact of a given factor. Results: It was found that twelve variables were significantly associated with injury severity. Rankings based on odds ratios showed that inadequate safety training (2.54), missing equipment protective system (2.38), being a non-union worker (2.26), being an equipment operator (1.93), and being on or around inadequately maintained equipment (1.58) produced higher odds for fatality. Conclusion: A majority of the earthmoving equipment accidents resulted in fatality. Backhoes were the most common equipment involved in accidents and fatalities. Struck-by accidents were the most prevalent and most fatal. Non-OSHA compliant safety training, missing seatbelt, operator not using seatbelt, malfunctioning back-up alarms, and poorly maintained equipment were factors contributing to accidents and fatalities. On-foot workers experienced a higher number of accidents than operators, while fatality odds were higher for the operators. Practical applications: Safety professionals should benefit from our findings in planning and delivering training and providing oversight to workers in earthmoving equipment operations.

Common human factors underlying worker fatalities in the waste and recycling industry

Research was carried out to identify common human factors underlying fatal incidents and to provide insights into possible options for concerted action to help reduce the likelihood of serious incidents or fatalities. The research reviewed 18 fatal incidents and included in-depth interviews with HSE inspectors involved in the incident investigations. Of these incidents, 12 were in ‘small and medium enterprises', SMEs (with less than 250 employees) and 6 in large enterprises (250 or more).
The research identified two priority human factors areas to tackle to reduce worker fatalities: equipment factors including design, use and maintenance; and safety management systems. For example, whilst it is foreseeable that some organisations (both SMEs and large) may think their SMS is adequate and well documented the analysis indicated this was not always the case.
The research also identified potential options for solutions to tackle these human factors issues. These options are intended to act as discussion points between the regulator and industry to inform decisions on what will work in practice and what can be adapted to work within industry. The options focus on: equipment selection, use and maintenance in the industry; and raising awareness of the risks associated with equipment and the legal requirements for equipment use and maintenance. Related to this is the need for effective safety management systems and the sharing of good practice.

Qualitative study on the control of hazardous energy on machinery using lockout and alternative methods

In Canada, like many countries, the national standard and provincial regulations require that workers performing maintenance, repair, and un-jamming activities on machinery must follow lockout procedures. However, the high number of accidents linked to hazardous energies and machinery shows that organizations have difficulty with the application of lockout arrangements or use of alternative methods. Therefore, it is important to understand how organizations implement lockout programs and procedures, and the extent to which they are in accordance with relevant standards and regulations. In this qualitative research, the application of lockout and alternative methods was studied in 13 organizations in Quebec, through a group interview, document review and site observation in each organization. In each organiztion, the researchers conducted a group interview and completed a questionnaire, which included more than a hundred questions on the lockout program, application of lockout procedures, alternative methods, sub-contractor management, training, and audit/inspection. The researchers then used observation data and documentation collected from each organization to verify interviewee responses and to finalize the questionnaire. The shortcomings found included: (i) incomplete lockout programs; (ii) missing steps in general lockout procedures; (iii) not reading the placards; (iv) using alternative methods without risk assessment; (v) poor training for alternative methods; (vi) absence of supervision and coordination of subcontractors; (vii) and lack of audit tools and documentation of audit results. Despite the shortcomings, actual lockout practices in the organizations visited were better than what was described in their lockout programs. Recommendations for addressing identified shortcomings are proposed.

Critères d’aménagement sécuritaire et ergonomique des postes de haleur et de support à casiers des homardiers du Québec

La pratique de la pêche commerciale est reconnue comme l'un des métiers les plus dangereux à l'échelle mondiale. Entre 2012 et 2014, elle a fait l'objet de deux projets de recherche qui ont été réalisés en Gaspésie et aux Îles-de-la-Madeleine. Le premier visait à analyser les activités de travail et les risques de chute par-dessus bord des homardiers ainsi que leurs déterminants, tandis que le deuxième consistait en l'étude des aménagements aux postes de travail « haleur et support à casiers ». La présente recherche découle de ces projets et porte sur l'amélioration de l'ergonomie et de la sécurité de ces deux emplacements. Les objectifs poursuivis sont : 1) mettre en évidence les avantages du point de vue de l'efficacité, de la sécurité et de l'ergonomie de certains aménagements aux postes de haleur et de support à casiers; 2) formuler des paramètres de conception et étudier la faisabilité de leur mise en œuvre lors de modifications d'installations existantes; 3) démontrer cette faisabilité en réalisant trois bancs d'essai; 4) décrire et analyser la démarche de coconception avec la collaboration des pêcheurs.
