In the ISA, we meticulously monitor the evolution of our cherished sport. Since the beginning of the growth of our activity around 2009 we have diligently documented accidents and near misses, presenting our findings through annual presentations and reports. <\/strong><\/h3>\n

For a glimpse into the unpredictable sides of our sport and in the attempt to give practitioners the opportunity to learn from the mistakes of others, we here provide the summary of the data we collect. Also check out our FailFriday segment on social media, featuring selected incidents, aiming for a safer and more informed community.<\/p>\n<\/div>

Risk Calculations by Slackline Variation<\/span><\/h1><\/span>

Just like any sport, our activity carries inherent risks, with a few unfortunate cases resulting in fatalities. Since the 1970s, the slackline variations have diversified, which prompts us to categorize them based on associated risks. <\/strong><\/h3>\n

The following table gives an overview on the risk of death while slacklining:<\/strong><\/h3>\n<\/div><\/div><\/div>

How does this work?<\/strong>
\nSuch death rates are calculated as the number of deaths in a given period (one year) divided by the average population number exposed to risk of death in that period (e.g. all highliners). This allows to calculate a death rate without knowing who highlines how often, and allows comparing the risk of dying while highlining to other sports activities, since this is a common approach of calculating risk.<\/span><\/p>\n

For comparison we provide you with a list of death rates from other sports:<\/strong><\/p>\n
