Heinrich's Accident Triangle is an industrial accident theory proposed by HW Heinrich in 1931. It is based on an assumption that the frequency of incidents is inversely proportional to the severity of the incident. Heinrich's assumed numbers are - for every incident that causes a major injury, there are 29 incidents that cause minor injuries and 300 incidents that cause no injuries.
