Quebec Research Group Develops App for Designing Horizontal Lifeline Systems
IRSST developed the web-based tool for engineers.
The Montreal, Quebec-based research group IRSST has developed a web-based tool intended primarily for engineers who specialize in designing horizontal lifeline systems for fall protection. IRSST is a nonprofit scientific research organization.
The analytical method developed by IRSST has been validated by using dynamic fall tests and with realistic simulations conducted using structural analysis software, according to the organization, which reports the dynamic fall-testing campaign consisted of 42 tests. It reports that the tool offers a user-friendly way to calculate variables such as tension in the cable at fall arrest, deflection of the cable, and clearance required. The app is intended to complement Protecting against Falls from Heights—Horizontal Lifeline Design, IRSST's technical guide.
Bertrand Galy, an IRSST researcher and co-developer of the app, explains the method and the use of the tool, in English, in a video posted on the organization's website. The goal was to develop a simple methods to help the engineers, he explains, adding the the tool is not intended for use by workers who will wear fall protection equipment.
