“…Por otra parte, estudios en Japón y Nueva Zelanda plantean la relevancia de la regulación para homologar los sistemas anticaídas y reconocen la importancia del uso de protección de bordes temporales para disminuir el riesgo de caída. Sin embargo, en el caso de Nueva Zelanda, aún faltan evaluaciones previas sobre recomendaciones de aspectos estructurales (Escamilla, 2016). Por otro lado, los estudios han analizado el tipo de proyectos en los que los sistemas de protección se deben utilizar.…”

El objetivo principal de este trabajo es presentar un análisis técnico de los distintos sistemas de protección de borde (barandas) y aportar al desarrollo de normativa sobre su uso en Chile. La metodología incluye una amplia revisión bibliográfica nacional e internacional para describir el contexto del uso de barandas. Se realiza un levantamiento de información en terreno para describir los principales problemas de uso de estos sistemas, tales como ritmo de avance del proyecto, singularidad de aspectos geométricos y arquitectónicos, requisitos estructurales y uso de soluciones artesanales. Se realizan 16 entrevistas semi-estructuradas a profesionales de la construcción y de empresas proveedoras nacionales para describir las distintas necesidades respecto a temas técnicos en el uso de barandas, destacándose aspectos como calidad de la información, trazabilidad, homologación y estandarización de productos. En conclusión, este estudio contribuye a especificar los criterios necesarios a aplicar en la industria de la construcción para promover el uso adecuado de protecciones de bordes para evitar caídas.

“…The construction industry has one of the greatest accident rates worldwide (Escamilla et al 2016), and an elevated probability of injuries and occupational illnesses (Yuan et al 2018). In Chile, the construction industry has an accident rate of 3.9%, much higher than the national average of 3.1%, considering 38 casualties due to workrelated accidents in 2018 (Superintendencia de Seguridad Social 2018).…”

The construction industry is known for its high rate of accidents. Among the different possible causes of this situation, we could find lack of sleep and fatigue. Chronic sleep deprivation is a determining factor in the deterioration of vigilance and alert, and consequently a risk factor for occupational accidents. Fatigue is the answer of our organism to sustained physical and mental stress. Regretfully, those topics have been ovelooked in the construction industry. The objective of this study is to understand better these phenomena, such as sleep duration and fatigue, and whether they are interrelated, and to propose strategies to mitigate them and contribute to the reduction of accidents in construction projects. We worked with 154 male construction workers from one Chilean construction company. To assess sleep quality, we used the Pittsburgh Sleep Quality Index (PSQI). To evaluate fatigue, we used a personal computer version of the Psychomotor Vigilance Test (PC-PVT) that measures alertness and vigilance. This 5-minute test was performed on construction workers on-site in the morning. Those people who took part in the test were classified into various groups according to self-reported sleep hours, namely: 7–9 h (26%), 5–7 h (61.7%), and <5 h (12.3%). These results were compared for three variables (Mean Reaction Time (RT), 10% faster, and 10% slower) using an Analysis of Variance (ANOVA) test. Differences were found for Mean RT and Slowest 10%, the difference being greater in the group that reported sleeping <5 h, but without statistical significance. Studies with a greater number of subjects and measurements are required throughout the working day.

The construction industry is known by its high rate of accidents. Among the different possible causes of this situation we could find lack of sleep and fatigue. Chronic sleep deprivation is a determining factor in the deterioration of vigilance and alert, and consequently a risk factor for occupational accidents. Fatigue is the answer of our organism to sustained physical and mental effort. Construction workers are prone to fatigue, since their work is characterized by heavy lifting and awkward work postures, so it is relevant to study it more thoroughly, especially regarding its association with sleep efficiency and quality. Regretfully, those topics have been very poorly studied in the construction industry. To understand better these phenomena and to propose strategies to mitigate it and contribute to the reduction of accidents in construction projects, the objective of this study was to understand if there is a relation among sleep duration and fatigue. We worked with 154 male construction workers from one Chilean construction company. To asses sleep quality we used the Pittsburgh Sleep Quality Index. One of their questions asked for average sleep hours in the last 4 weeks. To evaluate fatigue, we used a personal computer version of the Psychomotor Vigilance Test (PC-PVT) that measure alertness and vigilance. This 5-minute test was performed by construction workers on site in the morning. People was classified into groups according to self-reported sleep hours, namely: 7-9 hours (26%), 5-7 hours (61.7%) and <5 hours (12.3%). These results were compared for 3 variables (Mean Reaction Time, 10% faster and 10% slower) using an ANOVA test. Differences were found for Mean RT and Slowest10%, the difference being greater in the group that reported sleeping <5 hours, but without statistical significance. Studies with a greater number of subjects and measurements are required throughout the working day.
