Overview of Safety Risk Perception in Construction

Construction industry is a generally risky business; it remains one of the most dirty, difficult and dangerous with poor working conditions. Despite recent efforts to improve site safety, it still accounts for a disproportionate number of occupational-related fatalities what is supported by statistics. According to the International Labour Organization, it accounts for 30-40% of the world＇s fatal injuries. In The European Union around thirteen employees out of every one hundred thousands are killed each year. Hence, construction site safety is a matter of global concern. However it is not easy to describe and define how to deport safely at some actual site because the workers are exposed to many safety risks varying in con^nection with conditions of the construction realization and with technologies using. The paper provides a brief knowledge from the study comparing the construction safety in Europe and North America referencing to presented statistics. There are also analyzed, described and systemized the principal groups of construction safety risks; described the interdependencies among safety risks, affecting by spatial, technological and time parameters of the building process, as well as by the site conditions.

Roles and Responsibilities of Stakeholders towards Ensuring Health and Safety at Construction Site

Health and Safety issues in the construction industry are of much concern to stakeholders, particularly because of their impact on the industry. This paper explored the roles and responsibilities of stakeholders in ensuring health and safety at the construction site. A well-structured interview guide was adopted for the qualitative study. Content analysis was adopted for the analysis of the results. The study revealed that the twelve roles identified by the stakeholders are only limited to the few laws and regulations they are aware of. Whereas the Contractors identified provision of welfare facilities, provision of health and safety policy, and health and safety plan as their key roles, the Consultants’ role was mainly limited to provision of competent site agent and provision of site layout. Abiding by the contractors’ instruction was identified by the Construction Workers as their key responsibilities. The local government officials also identified enforcement of CHS laws and regulations and reporting of incidents to the appropriate authorities, whereas the traditional authorities identified the enforcement of CHS laws and regulations including bye laws and enforcement of customs as their key roles. The findings further show that the stakeholders failed to appreciate some key roles and responsibilities enshrined in CHS laws and regulations in Ghana. The findings contribute to knowledge on stakeholders’ responsibilities in ensuring CHS, and provide valuable reference and insight to practitioners on the roles and responsibilities of the various stakeholders. It is recommended to train and educate stakeholders on all the relevant laws and regulations on CHS in order to improve health and safety at the construction site. The government should also set up a body such as Construction Authority to educate, coordinate, monitor and audit the activities of stakeholders to improve CHS at construction sites.

OSH star enterprise pilot scheme——a partnership approach to improve the safety performance of construction industry in Hong Kong SAR

Background: The Occupational Safety and Health Council(OSHC) is committed to improve the safety performance of the high risk construction industry.In the past three years,about 40% of the fatal accidents in the construction industry were related to Renovation,Maintenance,Alteration and Addition(RMAA).Due to the poor safety record,some of the RMAA contractors have difficulty in obtaining the Employees' Compensation Insurance(ECI) cover in the market,or if they could obtain the ECI,the premium rate would be exceedingly high.In view of this,the OSHC,the Labour Department jointly launched"OSH Star Enterprise-Pilot Scheme on Safety Accreditation for the RMAA Industry",which prompts the industry to take practicable safety measures to improve the safety of working environment and reduce occupational injuries.The program also helps the stakeholders and insurers to identify safety-conscious contractors and thereby provide them with a favourable premium rate under the Employees' Compensation Insurance Residual Scheme(ECIRS).Objectives: The OSHC launches the Pilot Scheme to improve the safety performance of the RMAA industry through providing safety training,subsidizing enterprise to purchase safety equipment and providing safety audit.We also use financial incentive to encourage RMAA enterprises to join the Pilot Scheme-for those who are accredited as "OSH Star Enterprise"could receive a premium discount from the ERIRS when obtaining the ECI.The scheme also differentiates those safety-conscious and law-abiding enterprises from the poor performers,which helps the industry and public identifying the RMAA contractors who pay attention to work safety.Methods: The Pilot Scheme targets RMAA enterprises that employ less than 50 employees in Hong Kong.A three-pronged approach is used to improve the safety performance of the RMAA industry: the Pilot Scheme provides(1) financial support for the RMAA contractors to buy a transportable temporary anchor device and full body safety harness and its anchor system;(2) safety training on RMAA work safety and safety & health supervisor course;and(3) safety audit.Results: Enterprises that successfully pass the safety audit and satisfied the Scheme requirements will be accredited as"OSH Star Enterprise",which will be valid for two years.These enterprises can also be upgraded to"OSH Gold Star Enterprise"based on their continuous improvement in safety performance.OSHC will set up a register of OSH-accredited enterprises in RMAA works for reference of the public to facilitate their choosing of accredited contractors.The Employees' Compensation Insurance Residual Scheme Bureau will provide privileged premium rate for enterprises with OSH accreditation."OSH Star Enterprise"could enjoy 40% discounts when joining their insurance scheme.For example,a skilled worker's annual premium can be reduced by about HK $ 36,000.While,the "OSH Gold Star Enterprise"could enjoy 50% discounts when joining their insurance scheme,which means a skilled worker's annual premium can be reduced up to HK $ 45,000.Achievements: This Pilot Scheme offers practical assistance as well as attractive financial incentives for the RMAA industry to improve their safety performance.The Employees'Compensation Insurance Residual Scheme provides premium discounts for enterprises that have a good safety record.It provides incentive for RMAA contractors to actively participate in the Pilot Scheme.The Scheme demonstrates that by providing a safe working environment and appropriate personal protective equipment to workers,the enterprise not only helps to reduce the accident rate of the industry but also receive an economic return.The Pilot Scheme bridges stakeholders of RMAA industry,the government and the insurance industry creating an "all-win"situation.This partnership approach to prevent injuries and accidents in the construction industry could be an effective model for other industries.

The Importance of Occupational Health and Safety(OHS)and OHS Budgeting in terms of Social Sustainability in the Construction Sector

Nowadays,sustainability is one of the most important construction sector goals,as it is in most other sectors.However,sustainability in the construction sector is dealt mostly with its environmental and economic dimensions,and its social dimension remains in the background.This situation causes the Occupational Health and Safety(OHS),which is perhaps the most important issue within the scope of social sustainability,to be addressed on its own,and its relationship with sustainability to be not introduced clearly.This study discussed the relationship between social sustainability and OHS in the construction sector.Based on the fact that in construction projects,the sustainability goal should be revealed forward to a great extent at the design stage,how to contribute to OHS by budgeting OHS activities together with project activities was explained.We intended to contribute to the provision of OHS and thus the social sustainability of construction projects by revealing how the budgeting will be done and how much OHS budget will be,by referring to the studies in the literature conducted about OHS budgeting and presented robust numerical data.The study is expected to help construction sector stakeholders to understand the relationship between social sustainability and OHS and to provide a clear picture of the role of budgeting in this respect.

An Assessment of Occupational Health and Safety Regulations in Ghana: A Study of the Construction Industry

Occupational health and safety continues to be a major component of the built environment. The study investigates the effectiveness of occupational health and safety laws and regulations in the construction industry in Ghana and identifies the influencing factors. Face-to-face interviews were conducted among 49 stakeholders from four relevant groups—regulatory institutions, consultants, contractors, artisans and labourers. The findings of the study suggest that the existing occupational health and safety legal and regulatory framework is barely effective. Stakeholders were aware of the existence of some laws and regulations but mostly could not identify the specific laws and their relevant contents. Consequently, compliance is found to be irregular. The key recurring factors affecting effectiveness of occupational health and safety laws and regulations include: negligence and lack of priority for occupational health and safety, lack of training, lack of funds for occupational health and safety, lack of capacity of regulatory and supervisory institutions, and lack of occupational health and safety education within construction firms. The findings of the study are foundational in strategic interventions aimed at improving compliance with occupational health and safety laws and regulations in the construction industry of Ghana.

Construction Safety and Occupational Health Education in Egypt, the EU, and US Firms

The construction industry has been considered an accident prone industry. Alarming statistics indicate thatthe construction industry accounts for 55,000 fatal injuries each year. That is because construction sites are often filled with potential hazards that can lead to serious injury or death. Responsibility for these injuries may be attributed to a variety of individuals including owners, contractors or subcontractors, engineers, equipment manufacturers, and architects. This mandated a new safety culture to emerge resulting in a decline in the incidence rate of all recordable nonfatal injury and illness for construction workers. This study explores the safety culture encountered in twolarge construction companies in the USA and Egypt, over the last five years. Comparison of the results recorded in both companies was also conducted. The study also investigated the benefits of focusing on the occupational health in the construction field in Egypt and USA. In addition to the literature review, the research methodology used for this study was inspired by the Contextual Design (CD) Methodology. The study indicated thepositive impact of implementing safety programs on significantly reducing the recordable injuries. It also showed the benefits of focusing on occupational health and wellness, training, and education of workers.

Construction Workers’ Perceptions of Safety Practices: A Case Study in Mexico

Organizational characteristics and worker perceptions are among the main factors affecting the safety climate in construction sites. Although some perceptions of the workers may seem absurd to others, these components are part of their reality. Worker behavior is an extremely important factor in workplace safety as many accidents are often caused by insecure actions, in which combinations of human behavior are the consequence of such perceptions. The aim of this study was to explore workers’ perceptions of safety practices in their habitual work environment, a building site in Mexico. Worker perceptions of safety practices were captured using an instrument in which the following dimensions were taken into consideration: Education and training, Work motivation, Family and social integration, Work place integration, Safety awareness integration, and Accidents. The conclusion was that the workers have received very little education and possess a limited culture of safety awareness, which has led them to perceive that their lack of precaution is the main cause of accidents.

Framework for Improving Construction Health and Safety on Ghanaian Construction Sites

The enormity of the problem of construction accidents and hazards in the Ghanaian construction industry (GCI) calls for the need to engage in relevant research to equip stakeholders with the required knowledge to improve construction health and safety (CHS) and reduce site accidents and hazards. The complexity of the problem of accident causation explains a large number of conceptual models developed to aid the understanding of the dynamics involved in CHS. This paper involved a qualitative study to identify causes of accidents and hazards in the GCI and underlying issues requiring remedying and also a desk study to review Health and Safety related theories and concepts from extant literature to explain and contribute to the improvement of CHS. The paper contributes to the use of theories to advance studies on improving health and safety at construction sites, especially in developing countries like Ghana, where such studies have so far attracted little attention. The framework may enable construction stakeholders to easily identify problem areas on site and apply required improvement measures to create a healthier and safer construction site. The findings may provide useful knowledge to improve CHS and reduce site accidents and hazards, and also provide a multi-theory approach for understanding the dynamics of the complexity of the problems involved in CHS.
