Work at Heights Training: Conventional Approach With and Without Immersive Virtual Reality
Sponsor: Universidad Autonoma de Occidente
Summary
This study focuses on the design and evaluation of an innovative training protocol aimed at working at heights in the construction sector in the city of Cali. The main focus of this protocol lies in the use of Immersive Virtual Reality (IVR) and the measurement of biosignals to enhance workers' safety and preparedness. The training protocol is developed by creating virtual environments that simulate hazardous working conditions, allowing workers to practice high-risk situations safely and effectively. Additionally, the integration of biosignal measurements, such as heart rate variability and respiratory rate, is used to assess workers' stress levels and decision-making abilities during simulations. The protocol evaluation is conducted through a pilot study with real workers in the construction field. The results are analyzed to determine whether the use of IVR and biosignal measurement improves assertiveness and, therefore, safety, reduces workplace accidents, and increases workers' confidence in high-risk environments. The findings of this study will provide valuable insights into the effectiveness of IVR and biosignal measurement as training tools in the construction sector, which could have a significant impact on reducing workplace accidents and injuries. This innovative approach has the potential to enhance occupational safety and workers' preparedness in high-risk environments, thereby contributing to a safer and more efficient working environment in the construction industry.

Inmersive virtual reality
In addition to conventional training, IVR training aims to provide a detailed preview of the tasks and procedures required in the standard training with selected virtual scenarios: Scenario 1: Inspection and Use of Personal Protective Equipment (PPE): In this scenario, the worker will inspect the equipment to ensure it is in good condition and properly used: Harness, Helmet, Lanyards, Carabiners, Lifelines, Energy Absorbers Scenario 2: Working on an Elevated Metal Structure: Structure Ascent: Ascent Method: Use specific ascent systems, ensuring you are always connected to an anchor point. Positioning on the Structure: Secure Anchorage: Once the working position is reached, secure the anchor to a fixed and reliable point. Structure Descent: Unanchoring and Reanchoring: Unanchor and re-anchor at secure points as you descend. Additional Safety Measures: Weather Conditions, signage and delimitation: Scenario 3: Rescue at Heights: Accessing the Person in Danger, rescue Techniques.
Conventional training
The working at heights training provided by the National Learning Service (SENA) in Colombia includes key steps to ensure safety and proper equipment use: * Harness Use: Inspect for damage, wear it like a vest, and ensure correct orientation. Adjust shoulder and leg straps for comfort and secure the chest strap. * Final Check: Verify D-rings are correctly positioned, and all buckles are securely fastened. * Helmet: Inspect for damage and adjust for a secure fit. * Lanyards: Select in good condition, connect properly, keep tension, and avoid overloading. * Carabiners: Use certified carabiners with functioning locks, connected to proper points. * Lifelines and Energy Absorbers: Install and tension lifelines properly; check energy absorbers before use. * Climbing/Descending: Maintain three contact points and secure tools to avoid accidents.
