Adopting incorrect positions is the main cause of falls from scaffolding and ladders

06.06.2008
Adopting incorrect positions is the main cause of work accidents produced by falling from platforms and ladders, and is also related to workers’ lack of knowledge of regulations, according to a study prepared by researchers from the University of Vigo (Pontevedra) and published in the online version of the magazine Science Safety.

One of the authors of the study, Teresa Rivas, from the Mining Engineering School at this university explained to SINC that job duration is also related to adopting bad positions and lack of knowledge of regulations, as a result of which shorter tasks are associated with more falls and less well-trained workers. On the other hand, workers that carry out longer tasks are better prepared for dangerous situations.

To carry out this study, authors surveyed almost 400 workers from 103 companies from industry, construction and the services sector while performing their tasks at height. Bayesian networks, one of the so called “automatic learning” statistical techniques enabling graphic expression of relations of dependence between variables, as well as making estimates in probalistic terms of the influence of each variable and its interaction in the type of fall, were used to analyse researchers’ data.

In previous work these scientists have already analysed the capacity of predicting and interpreting different automatic learning techniques and concluded that Bayesian networks, apart from having a comparable predictive capacity to other statistical methods, “have an excellent interpretative capacity”. Rivas points out that Bayesian networks can be improved with new data, as a result of which they are a very useful tool for identifying causes of accidents and establishing the bases of understanding for a “solidly based” prevention policy.

José María Matías, mathematician from the Department of Statistics at the University of Vigo who also participated in the study, says that these types of techniques can be used for analysing causes “because there is continuous data on victims of work accidents, but beyond just the numbers what we need to look for is how to avoid such accidents, and this is where these methodological contributions play an important role”.

The researcher Rivas concluded that knowing the dependence relationship between the causes of the accident offers experts useful information for improving health and safety at work management models.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
