The impact of construction related accidents to the individual, the construction sector and the economy is huge. In Malaysia about 6000 workers’ related accidents are reported annually. Scaffold accidents are one of the major causes of injury and death on Malaysian construction sites. This research investigated the scaffolding accidents during maintenance work in the Malaysian construction industry. This study provides answers to two questions: 1) what are the causes of scaffolding accidents during maintenance work? and 2) what are the possible measures to reduce scaffolding accidents during maintenance work? Primary data were collected through survey interview techniques involving 10 maintenance construction stakeholders. The research revealed that the scaffold accidents that occurred during maintenance works are due to lack of a fall protection system, lack of proper baseplate, user behavior, lack of proper guardrail and weather conditions. To reduce scaffolding accidents during maintenance works adequate poor cross bracing, safety netting, jack base, pin lock and adequate inspection of the scaffolding during operations are required. Implicit in the findings of this research is that scaffold accidents are due to behavioral issues of the sites operative and contractors’ organizations as whole. The findings provide feedback and feed for-ward information and knowledge to construction site operatives.

Construction falls are a leading cause of fatalities in almost every construction industry around the globe, and fall protection systems are the key measures to ensure the safety of labor crews. This study develops a fuzzy multi-criteria decision-making model integrating analytical hierarchy process, fuzzy set theory and Technique for Order Preference by Similarity to Ideal Solution approach to analyze the overall performance of various fall protection plans for construction projects, which focuses on evaluation and selection of the appropriate protection plan considering the most influential safety, productivity, and economy factors. Results show that the optimal plan can be effectively identified and determined among all potential alternatives. Besides, the model overcomes the shortcoming of weight value uncertainty and ambiguous decision information through membership function calculations. As a result, it provides guidance for the improvement of construction performance, intending to minimize fall risks, improve labor productivity, and save economical cost on the jobsites.

Sudáfrica se enfrenta en la actualidad a nuevos retos en el sector de la construcción. Por un lado, la necesidad de un nuevo modelo de sector energético que ayude al crecimiento sostenible del país así como a su modernización, y por otro lado la necesidad urgente de mejorar las altas cifras de siniestralidad que el sector de la construcción sigue teniendo a fecha de hoy. Para ello, en febrero del año pasado, 2014, el Ministerio de Trabajo sudafricano publicó un nuevo texto legal – Construction Regulations 2014 -, modificando al que ya existía en vigor– Construction Regulations 2003, regulando las nuevas obligaciones en materia de seguridad y salud de todos los intervinientes haciendo especial hincapié en la figura del Promotor (“client”) como eje vertebrador de la promoción de la seguridad y salud en las obras de construcción. La aparición de la designación obligatoria de nuevos profesionales en materia de seguridad y salud tanto para el promotor como para las empresas participantes (“principal contractor” y “contractor) dotan a la actual organización preventiva de obra de una mayor estructuración y claridad a la hora de acometer la implantación de los principios básicos de la gestión preventiva a través del seguimiento de los trabajos por parte de dichos profesionales basándose en documentos de gestión preventiva establecidos de igual forma (“risk assessment”, “health and safety specification”, “fall protection plan” y el “health and safety file”). El registro de dichos profesionales ante la SACPCMP - “South African Council for Project and Construction Management Professions”, obligatorio a partir del 6 de agosto de 2015, dotará de una mayor profesionalización de los técnicos que desempeñen dichas funciones; cuestión fundamental para seguir trabajando en la mejora de los índices de siniestralidad del sector de la construcción en Sudáfrica. Abstract South Africa is currently facing new challenges in the construction sector. On the one hand, the need for a new model of energy sector to assist the sustainable growth of the country and its modernization, and secondly the urgent need to improve the high number of accidents rates that the construction sector still keeps to date. On last February, 2014, the Ministry of Labor released a new construction regulations – construction regulations 2014 – modifying to Construction Regulations 2003, regulating the new duties and obligations on health and safety belong to all agents involved with special emphasis on the role of “Client” as the backbone of promoting the health and safety matters on construction sites. The emergence of new mandatory professionals appointments on health and safety both for client and principal contractor – contractor, endow to current safety organizational chart on site with a better structure and clarity to undertake the implementation of the basic principles of preventive safety management through monitoring by these professionals based in all new safety documents established likewise ("risk assessment", "health and safety specification", "fall protection plan "and" health and safety file "). The register of these new safety roles through SACPCMP - “South African Council for Project and Construction Management Professions”, will come into in force on 6th august, 2015. This register will provide better professionalism of technicians who perform those duties, essential point to keep improving the accidents – incidents rates on construction sector in South Africa.
