Mechanical Contracting Safety Issues

The purpose of this paper is twofold: (1) to determine jobs/tasks associated with current injury, illness, and fatality trends in the mechanical contracting branches of the construction industry; and (2) to identify current safety practices associated with the reduction of risk of these injuries, illnesses, and fatalities. To achieve the project objectives, a survey was designed and sent to Michigan mechanical contractors. To design an adequate survey, the research team first collected background information using U.S. Bureau of Labor Statistics online database, published research, and contractor interviews. Fourteen of the 50 mechanical contracting surveys distributed were completed. The pilot study found eye injuries due to grinding and welding and upper extremity cuts due to sheet metal to be the most frequent mechanical contracting task/injury combination.

This paper presents and discusses the results of this study.     

Factors That Influence Safety Performance of Specialty Contractors

In the construction industry specialty contractors perform most of the construction work. Given their impact on the industry, the safety performance of specialty contractors should be of concern to the construction industry. This paper describes a study conducted to identify factors that significantly influence the safety performance of specialty contractors. The study was composed of separate surveys of three different specialty contractor populations—a variety of trade contractors located primarily in southern Nevada, roofing contractors in the state of Florida, and the regional offices of a large, nationwide mechanical contractor. While there appeared to be contradictions between the surveys in some areas, the study concluded that specialty contractor safety performance was consistently influenced, in part, by a number of factors. The factors shown to positively affect safety performance include minimizing worker turnover, implementing employee drug testing with various factors initiating the testing, and training with the assistance of contractor associations. Safety incentive programs were not necessarily associated with better safety performance. Growth in company size was found to be associated with improved safety performance as well.     

Center for Excellence in Construction Safety

The National Institute for Occupational Safety and Health (NIOSH) has funded the establishment of a Center for Excellence in Construction Safety at West Virginia University. The overall objectives of the Center include: (1) The promotion of hazard control components in engineering curricula; (2) the promotion of hazard awareness and safety‐related knowledge and skills specific to the construction industry; and (3) the promotion of the consideration of safety issues during project design for the purpose of reducing injury during construction. Specific tasks to be accomplished by the Center include: (1) The development of course materials and instruction on construction safety for civil engineering students at the undergraduate and graduate levels; (2) the promotion of such course materials for adoption by other civil engineering academic institutions; (3) the design and conduct of projects related to the improvement of current construction practices that would develop design parameters to reduce trauma during the construction phase; and (4) the establishment of techniques for the collection and dissemination of construction safety information, educational materials, developed guidelines, and design criteria to engineers, architects, contractors, and trade unions.     

The role of exhaustion and workarounds in predicting occupational injuries: A cross-lagged panel study of health care professionals.

Occupational injuries remain an important concern for employers, particularly in the health care industry where injury rates have increased despite decreases in other industries. Testing the notion of resource investment from conservation of resources theory, I predicted that exhaustion would be associated with a greater likelihood of safety workarounds (alternative work processes undertaken to “work around” a perceived block in work flow, such as a safety procedure). Furthermore, I hypothesized that safety workarounds would lead to a greater frequency and severity of occupational injuries. I found support for this mediation model with a 2-sample, 3-wave survey study of a variety of health care professionals (nurses, sonographers, and others). I discuss the implications of this research for future research in occupational safety and provide ideas for the reduction of injuries through action research strategies that reduce burnout and workarounds.

Construction Safety in Kuwait

In gulf region countries like Kuwait, the construction process can become very challenging. In this paper, we analyze construction-related accidents in Kuwait including type of accident, type of injury, body part injured, and accident outcome for the years 1996–2007. We present examples of recent cases and evaluate these cases presenting current Kuwaiti rules and legislation and providing suggestions for ensuring a safer construction environment. As this research shows, the construction industry is the most hazardous industry in Kuwait. On average, falls are the major type of accident (33.2%) followed by being crushed or struck by a falling object (25.2%). Use or misuse of tools caused the third largest number of accidents in Kuwait (18.1%). The most frequent type of injury is fractures (52.6%) and the most common injured body part is the upper body (53.4%). An average of (82.7%) of victims of construction accidents in Kuwait sustain permanent disabilities. It is clear that the Kuwaiti construction industry has a safety problem and that there is a pressing need to change current practices and legislation in construction and building sites.     

Comparative Study on the Perception of Construction Safety Risks in China and Australia

Safety is a major concern in the construction industry because fatalities and injuries from construction work bring great losses to individuals, organizations, and societies as a whole. This paper aims to understand how construction personnel perceive safety risks in China as compared with those in Australia. Postal questionnaire surveys were used to collect data on safety risk perceptions from the two nations. The safety risk factors were assessed using a risk significance index based on the likelihood of occurrences and the impacts on safety performance. The survey results revealed that in China the main perception of safety risks came from human-and/or procedure-related issues, with “low/no safety education” paramount, followed by “inadequate fire prevention and electrical prevention procedures,” etc. In contrast, the major safety risks perceived in Australia were related to the environment and physical site conditions with “contamination of land, water and air” ranked first, followed by “unforeseen excavation of soil,” etc. To minimize construction safety risks in China, this paper suggests that the government should develop collective legislation and safety protection procedures, and enforce safety education and training to all site participants. Risks related to environmental and site conditions were generally realized by the Australia construction industry, which were not highly acknowledged in China. This may also bring imminent attention in this regard to the Chinese government.     

Safety Management in Construction: Best Practices in Hong Kong

Safety issues have gained vital importance throughout the construction industry. Many construction companies around the world are implementing safety, health, and environmental management systems to reduce injuries, eliminate illness, and to provide a safe work environment in their construction sites. This paper describes an exploratory study of site safety management in construction sites’ environments. It explains a successful, modern safety, health and environmental management system for a leading construction company based in Hong Kong. A typical site-specific safety plan was utilized to provide safety guidance throughout the construction project. A safety management survey was conducted to determine the status of safety in the construction sites. All employees of the company and its subcontractors participated in the survey from 20 construction projects. In total, 1,022 valid records were obtained from the construction sites. The analysis provided useful information on eight aspects of construction safety, including safety policy and standards, safety organization, safety training, inspecting hazardous conditions, personal protection program, plant and equipment, safety promotion, and management behavior. The findings of the survey provide practical knowledge to construction project managers and construction safety practitioners in order to make their sites safer. Insights and discussions are given in this paper.     

Roofing Materials’ Contributions to Storm-Water Runoff Pollution

Development in sensitive watersheds continues to pose environmental problems for receiving waters. One contributor to this long-term pollution is building and other construction materials. However, the long-term effect of many building materials on the environment has not been quantified due to limited testing of these materials prior to sales and installation. Laboratory “leach” testing of commercially available roofing materials by this research group indicated that the potential for release (primarily nutrients, lighter hydrocarbons, pesticides, and metals) is substantial. Testing of metals’ release from aged roofing panels also has shown that the potential for pollutant release still exists after 60?years. The data missing from a complete evaluation of many roofing materials is behavior over the lifespan of the material, including the critical period of initial exposure. The 2?years of runoff data from a pilot-scale testing of these materials indicated substantial concerns regarding zinc from uncoated galvanized metals and copper from treated woods in this early part of the materials’ lifespan, plus the potential for long-term nutrient releases in the runoff from several roofing types.     

Safety Climate in Construction Industry: A Case Study in Hong Kong

Because of the characteristics of decentralization and mobility in the construction industry, safety culture is crucially important. A comprehensive safety climate questionnaire survey was conducted with all sites and employees of a leading construction company and its subcontractors in Hong Kong. In total, 4,719 records were returned from 54 sites. By means of factor analysis, a 15-factor structure that defines the dimensions of the safety climate has been extracted. Compared with previous research studies, the roles and influences of fellow workers, and safety resources on the safety climate are emphasized. The results also confirm the feasibility of exploring common factors of the safety climate in the construction industry. Through further analysis, logistic regression was used to explore the relationship between the safety climate and personal characteristics. Statistically significant relationships were found between safety climate and personal characteristics, including gender, marital status, education level, number of family members to support, safety knowledge, drinking habits, direct employer, and individual safety behavior. This research is a case study and the results are derived from the data of one company, but the methodology of this research may be useful as a model for further research, and the findings may provide useful information for construction managers and safety practitioners in the construction industry to improve their safety culture.     

Differences in Occupational Injuries, Illnesses, and Fatalities among Hispanic and Non-Hispanic Construction Workers

The U.S. Census Bureau estimates that one in four persons in the United States will be of Hispanic origin by 2050, up from one in eight in 2002. Driven by immigration, this dramatic growth in the Hispanic population will present unique challenges in the workplace. In construction, the increase in the Hispanic population has enabled the industry to meet its workforce demands. Unfortunately, this has occurred with costs in the health and safety of Hispanic construction workers. Using data from the U.S. Bureau of Labor Statistics’ current population survey, current employment survey, survey of occupational injuries and illnesses, and census of fatal occupational injuries, this study examines relative differences in injuries, illnesses, and fatalities between Hispanic and non-Hispanic construction workers by occupation. The findings show that differences in injuries, illnesses, and fatalities exist between Hispanic and non-Hispanic construction workers, although not always unfavorably toward Hispanics, and the difference does vary by occupation. The implication of the increasing size of the Hispanic construction workforce with respect to construction safety and health training needs is discussed.     

Development and Initial Validation of Sustainable Construction Safety and Health Rating System

This paper presents a study to develop and validate a sustainable construction safety and health (SCSH) rating system. The rating system provides an opportunity to rate projects based on the importance given to construction worker safety and health and the degree of implementation of safety and health elements. A Delphi survey using an expert panel of 12 experienced safety and health professionals representing different sectors of the construction industry was employed to develop the SCSH rating system. The study resulted in a rating system consisting of a total of 50 safety and health elements organized into 13 categories. Each category contains safety and health elements which carry credits based on their effectiveness in preventing construction worker injuries and illnesses. The rating system was initially validated based on data from 25 construction projects and found to accurately represent the safety performance of large projects. The SCSH rating system can be used as an effective tool to develop and plan construction safety and health programs and evaluate the potential safety performance of construction projects.     

Impact of Green Building Design and Construction on Worker Safety and Health

Sustainable, or “green,” rating systems, such as the United States Green Building Council’s Leadership in Energy and Environmental Design (LEED), are leading to changes in the way owners, designers, and contractors approach the design, construction, and operation of buildings. The processes and features included in green design and construction may have positive and/or negative impacts on construction worker safety and health. This paper presents the findings of a research study of the impact of green building design and construction practices on construction worker safety and health. Occupational Safety and Health Administration (OSHA) recordable and lost time injury and illness data from green projects (as identified by LEED) and from nongreen projects was collected through a structured questionnaire survey. The data collected was analyzed to test for the presence of a difference in OSHA recordable incident rates (RIRs) and lost time case rates (LTCRs) between green and nongreen projects. It was found that there was suggestive, but inconclusive evidence of a statistically significant difference in the RIRs of the green and nongreen building projects included in the study. No statistically significant difference was found between the LTCRs for the green and nongreen projects included in the study. The study findings provide valuable information to the construction industry for the purposes of project safety planning and the assessment of safety and health on projects.     

Psychosocial Factors and Musculoskeletal Disorders in the Construction Industry

Musculoskeletal disorders (MSDs) constitute more than half of the total injuries and illnesses within the construction industry. The aim of this study was to assess the prevalence of MSD among construction workers and identify the psychosocial and physical risk factors associated with their occurrence using an on-site survey instrument. One hundred forty seven construction workers (representing three trades) participated in the study. The 1-year prevalence of MSD was high with 61.2% reporting severe symptoms and 39.7% having some functional impairment due to MSD. Physical task requirement was the most important factor associated with MSD reflecting the physical nature of construction work. Economic and performance factors were the most stressful psychosocial factors reported and significantly increased the risk of reporting MSD. The findings of this research underscore the independent role that psychosocial factors play in the health and safety of construction workers. Understanding this role is imperative for practitioners and academics alike in the quest to make construction a safer work environment for all workers.     

Premium-Rating Model for Workers’ Compensation Insurance in Construction

Providing adequate workers’ compensation insurance (WCI) is mandatory by legislation in most countries for employers to hire workers. It is enforced to safeguard the interests of occupational injury victims while eliminating their employers’ financial burden of compensation. WCI’s significance in construction is immeasurable because the construction industry appears to be recording higher injury and fatality rates globally. On the other hand, insurance companies must be meticulous in deciding premiums for WCIs for construction projects. Traditionally, insurers have been adopting the experience modification rating technique for premium-rating of WCI. However, this technique has been proven ineffective for construction applications due to the unique characteristics of construction projects. Hence, a new premium-rating model for construction was developed and tested in the Singapore general insurance industry. The proposed model streamlines structured analyses of project hazards, contractors’ safety management systems, market conditions, and insurers’ internal factors to decide optimal premiums. Moreover, it infuses the partnering notion in WCI for construction. The implementation of the proposed model in the insurance industry would facilitate accident control in the construction industry and thereby loss minimization for insurers.     

Safety Climate in Construction Site Environments

This paper discusses empirical research aimed at examining the relationship between the safety climate and safe work behavior in construction site environments. A literature review has identified a number of independent constructs with the potential to affect the safety climate. A research model was developed based on the hypothesis that safe work behaviors are consequences of the existing safety climate, which, in turn, is determined by the identified independent constructs. A questionnaire survey was used in order to facilitate the collection of information from construction sites. The model was tested using structural equation modeling. The paper presents the results of testing the research model. The results corroborate the importance of the role of management commitment, communication, workers’ involvement, attitudes, competence, as well as supportive and supervisory environments, in achieving a positive safety climate.     

Effect of Safety and Environmental Variables on Task Durations in Steel Erection

In spite of the efforts by government agencies, labor organizations, and researchers in the field of health and safety, injuries and fatalities continue to affect the construction industry. In 2002 the construction industry had the undesirable distinction of having two of the most dangerous occupations in the United States, with fatalities among structural steel workers at 58.2 per 100,000 workers (fourth highest rate) and among construction laborers at 27.7 per 100,000 workers (ninth highest rate). Costs associated with construction accidents, such as increased insurance premiums and medical expenses, and loss of productivity are also concerns in the industry. It has not been demonstrated how unsafe working conditions affect worker performance, and the impact of unsafe work practices on worker performance has not been quantified. This paper describes a methodology that included direct observation of steel erection activities and statistical analysis of task duration data. The data collected at steel erection sites included safety conditions such as the use of personal protective equipment (PPE), elevation of the work area, environmental conditions such as temperature and humidity, and worker performance in the form of task durations. Analysis of variance (ANOVA) analysis of 186 of steel erection task durations collected over a six-month period showed that the use of personal protective equipment (PPE), the time of day during which the operation was being performed, the elevation at which the work was being performed, and the presence of decking below the work area had statistically significant effects on the durations of steel erection tasks.     

Structural Failures During Construction

Structural failures involving components, assemblies or partially completed structures often occur during the process of construction. Many minor failures are not reported in the media, but these events contribute cumulatively to the costs of construction. Significant catastrophic collapse is always economically disastrous, and may result in injury or death to construction workers. An overview is presented of the factors contributing to the frequency of these occurrences, and to the vulnerability of structures during the construction phase. Recommendations for improved practices are also presented. Public interest has recently focused on the safety record of the construction industry, with over 2,200 deaths recorded in 1984. The inherent risks in construction arise from a variety of causes, including excavation problems, equipment failures, and trenching accidents. Understanding and minimizing the potential for structural failure during construction is one important aspect in the improvement of the construction industry safety record.     

Developing a Model of Construction Safety Culture

The concept of safety culture is relatively new in the construction industry; however, it is gaining popularity due to its ability to embrace all perceptional, psychological, behavioral, and managerial factors. To address the lack of a verifiable process to analyze construction safety culture, this technical note presents a robust conceptual model that has its roots firmly entrenched in pertinent academic and applied literature. It provides a critical review of the term “safety culture”; along with distinct yet related concepts (i.e., safety climate, behavior-based safety, and safety system). It also compares the proposed model with available safety culture models in order to demonstrate its applicability in construction site environments.     

Measuring Safety Climate of a Construction Company

Safety climate can benefit contractors, specialty contractors, and owners of industries by providing them with the knowledge of attitudes and perceptions that can help to consistently achieve better safety performance. The objective of this research was to determine safety climate that would enhance safety culture and positively impact perceived safety performance on construction projects. A safety climate questionnaire survey was conducted on the construction sites of a leading construction company and its subcontractors in Hong Kong. Approximately, 1,500 hard copy questionnaires were distributed and the response rate was excellent, resulting in 1,120 valid questionnaires being collected from 22 construction projects. By means of factor analysis, two underlying safety climate factors were extracted, accounting for 43.9% of the total variance. Multiple regression analysis confirmed that these climate factors, “management commitment and employee involvement” and “inappropriate safety procedure and work practices” were significant predictors of workers’ perceptions of safety performance. The findings indicated that the relationship between perceived safety performance and “inappropriate safety procedure and work practices” was inversely correlated. The results suggest that safety climate can be used as an effective measure of assessing and improving site safety for projects under construction. The findings of this study and the methodology might be useful for research at other construction sites in other regions and countries. This work provides useful information for project managers and safety practitioners who desire to improve safety climate and safety performance on construction sites.
